LUKE Arm System
This chapter provides an overview of the LUKE arm system which includes the
socket, arm, batteries, AC Adapter, charging pad, and arm inputs and outputs.
Prior to using the LUKE arm system you must have met with your prosthetist.
During the meeting(s) the prosthetist will have performed a number of steps such as:
•
design and build a custom socket to attach the arm
•
pick the arm configuration and arm parts to best fit your needs
•
set up and configure the arm
•
allow you to test the arm system in a controlled setting
Once the prosthetist feels that you have met all demands in order to use the arm
they will allow you to use the arm. You should clearly understand how the
prosthetist has set up your arm prior to using the arm.
Indications for Use
The LUKE arm system consists of a prosthetic arm and accessories which are used
by a certified prosthetist to create a full upper extremity prosthesis indicated for
individuals, age 18 years and older, who have partial or full upper limb amputations
or congenital defects. The device is used to assist in activities of daily living (ADLs).

Chapter 1: LUKE Arm System
LUKE Arm System
The LUKE arm system is comprised of a specific arm type and several accessories
depending on the arm type. The arm system is described below.
RISK OF DEATH OR SERIOUS HARM
Do not take apart or change the arm or connected parts. This could lead to
harm.
Based on your arm’s type and setup you may not have some of the following
parts.
Note the following concerning the LUKE arm system:
•
The arm is internally powered (when under battery power).
•
The arm is designated Class II (when plugged into the AC Adapter).
•
The arm and all body worn accessories are Type BF applied parts.
The IMUs have an IP57 rating. The other body worn components of the arm
system, when installed and covers are in place, have an IP52 rating. The IP
rating specifies the strength of the enclosure against solids (such as dust) and
liquids. An IP52 rating provides resistance to light rain and fine dust. An IP57
rating provides resistance to fine dust and submersion to depths of 1 m.

LUKE Arm System
Arm Types
Your LUKE arm is one of the three types listed below and shown in Figure 1. Your
prosthetist will have chosen the arm type that best fits your needs and set up the
arm for the right or left side as well as proper length.
Shoulder Configuration (SC)
This arm type is for those amputees with little or no residual limb or for those
amputees with limited movement or other restricting factors in their residual limb.
Humeral Configuration (HC)
This arm type is for those amputees with a residual limb below the shoulder but not
including the elbow.
Radial Configuration (RC)
This arm type is the shortest of the three and is for amputees with a residual limb
below the elbow.

LUKE Arm System
Batteries and Holster
There are two battery types used to power the arm. Which battery type is used
depends on your arm type and how your prosthetist configured the power to the
arm. The two batteries are:
Internal Battery
This battery may be used to power the SC and HC arms and is located within the
arm’s forearm. See Figure 2.
Depending on how your prosthetist configured your arm you may not have an
internal battery.

Chapter 1: LUKE Arm System
External Battery
This battery, see Figure 3, is normally worn on a belt or in a pocket and is used in
one of two ways:
•
In SC and HC arms, with an internal battery, it may be used to supplement
power to the arm.
•
In RC arms and in SC and HC arms, without an internal battery, it is used
standalone to power the arm.
The external battery is used with an external battery holster to power the arm. See
External Battery Holster for more information.

(Outside the Arm)
SC, HC, and RC Arms
External Battery Holster
The external battery is mounted in a holster which in turn can be clipped to a belt or
worn in a pocket. See Figure 4. The belt clip can be attached to the holster so that
the external battery is in either the vertical or horizontal position. There are two
versions of the holster; one with an ON/OFF button and power LED and one
without. For more information see Power ON/OFF Button Location.

Battery Chargers and Charging Dock
There are three components used for charging the batteries: a charging pad, an AC
Adapter, and a charging dock. The AC Adapter is used with the charging dock to
charge the external battery. To charge an internal battery, the AC Adapter plugs
directly into the arm.

The ACI Module, see Figure 8, receives signals from user inputs (e.g., surface EMG
electrodes and pressure transducers) and sends them to the MAC which in turn
controls the arm. The ACI Module provides four user inputs and connects to the
arm.
The arm supports up to four IMU/ACI modules at a time in multiple
combinations, with a maximum of two IMUs. For example, your prosthetist
may configure the arm to support two IMU modules and two wired ACI
modules or four wired ACI modules and no IMUs.

LUKE Arm System
Input and Output Control Devices
The arm uses several input devices and a single output device to control the arm.
The following sections describe these devices.
IMUs (Inertial Measurement Units)
IMUs are placed on top of your shoes and command motion or grip selection by
having you tilt your foot. See Figure 9. To install the IMUs see Installing IMUs.
Figure 9. Example Inertial Measurement Unit
Inertial
Measurement
Unit
EMG (Surface EMG Electrodes)
EMGs are placed on your skin or embedded into your socket to maintain contact
against your skin. EMGs are used to read electrical signals from underlying muscle
contractions. EMGs command motion by having you contract the selected muscle.
Figure 10 shows an example of a type of EMG.
Figure 10. Example EMG
Surface EMG
Electrodes
When donning the arm system, static electricity discharge to EMGs can
damage them. To minimize the chance of EMG damage, touch any metal on
the arm before touching the EMGs. If you think the EMG is not working
correctly, see Troubleshooting the Arm.

Setting Up the Arm
This chapter provides information on how to set up the arm. Based on how your
prosthetist configured your arm, you may need to install some arm parts and then
don the arm to ensure proper fit prior to using the arm.
Topics in this chapter include:
•
Installing IMUs
•
Donning (Putting On) the Arm
Before installing the arm parts and donning the arm be sure to visually inspect
all the arm parts and the arm for any sign of damage. If there is any sign of
damage, contact Technical Support. See Contacting Technical Support.
Installing IMUs
If your arm’s control scheme calls for IMUs with shoe clips, you can install them at
this time. There are two steps to installing the IMU:
1. Attaching the IMU to the shoe clip.
2. Attaching the shoe clip to your shoe.
If you need help putting on and taking off the IMUs with shoe clips, have your
caregiver available at this time.
The IMUs have an IP57 rating. The IP rating specifies the strength of an
enclosure against solids (such as dust) and liquids. An IP57 rating provides
resistance to water at depths up to 1 m (39 inches) and resistance to fine dust.

r49
Chapter 4: Setting Up the Arm
The IMUs will not provide data if dramatically tipped (close to vertical). Be sure
to position the IMU as close to level as possible when installing the IMU. If you
attach the IMU to your shoe at a severe angle to begin with, the IMU will not
provide the full range of motion after zeroing.
Installing the IMU to the Shoe Clip
To install the IMU to the shoe clip see Figure 21 and perform the following steps:
Be sure to install the IMU(s) onto the correct foot as configured by your
prosthetist. DO NOT SWAP THE IMU(s) DURING INSTALLATION.
1. Slide the tabbed end of the IMU into the open end of the shoe clip.
When installing the IMU onto the shoe clip, please ensure the following:
•
The Front Arrow label on the bottom of the IMU is facing towards your
toes.
•
Keep the IMU aligned with the direction of movement. This will prevent any
cross talk from occurring.
2. Press down on the IMU until the shoe clip retention tab snaps into the IMU slot.
Ensure the IMU is fastened securely to the shoe clip.
50
•
The shoe clip can be put on the shoe either before or after the IMU is
installed on the shoe clip.
•
You can attach the IMU to the shoe by alternate means (i.e., straps or
pockets) as long as it is securely attached.

Installing the Shoe Clip to Your Shoe
To install the shoe clip to your shoe see Figure 22 and perform the following steps:
•
Note that the shoe clip can be installed onto your shoe with the shoe off
your foot or on your foot.
•
Once you have installed the shoe clip, the shoe clip can remain on the
shoe.
1. Orient the shoe clip so that the open end of the clip is facing towards your toes.
2. Slide the shoe clip under the laces of the shoe (left or right).
When installing the shoe clip to the shoe, please ensure the following:
•
The shoe clip passes through at least two of the shoe’s laces to ensure the
clip is secure and stable.
•
The Front Arrow label on the bottom of the IMU is facing towards your
toes.
3. Tighten the laces to secure the IMU and shoe clip to the shoe.
4. If you have not already done so put on the shoe.
5. Once you have installed the IMUs you can don (put on) the arm. See Donning
(Putting On) the Arm.

Waking a Sleeping IMU
The IMUs do not contain an ON/OFF button. An IMU that is awake and set
up to communicate with an arm will do so once the arm is powered ON. See
Waking a Sleeping IMU and Initializing the Arm.
Location and Orientation of the IMUs
During the configuration process your prosthetist will have located and oriented the
IMUs to ensure proper operation of the arm. Be sure to locate and orient the IMUs
per your prosthetist’s instructions.
Waking a Sleeping IMU
When an IMU has not communicated with the arm for more than 30 minutes, the
IMU reverts to a sleep mode to conserve the battery. When in sleep mode the IMU
is not listening for arm communication.
As a result, if the IMU is in sleep mode when the arm is turned on, it will not
connect with the arm. This results in the Grip Select LEDs sweeping while the arm
is trying to find the IMUs. If no IMUs are found, the System Fault Icons on the wrist
display blink along with an “IMU Comm Lost” fault code. Shaking your foot with
the IMU attached wakes the IMU from sleep mode so that the IMU is ready to
communicate with the arm once the arm system is powered up.
An IMU that has been shaken awake is waiting to communicate with the arm. IMUs
that are not actively communicating with an arm blink the battery state of charge
whenever they are shaken, regardless of whether they are sleeping or not.
If the IMU does not communicate with the arm within five (5) minutes of being
shaken awake, the IMU reverts back to sleep mode to conserve the battery.

Chapter 5: Using the Arm
IMU - Walk Detect
The IMUs are designed to detect rapid foot movements (such as those seen while
walking) and not use these movements as arm commands. For example, if you
shake your feet the IMUs would detect this as motion other than a normal
command. When walk detect is active, the white Arm Mode LED blinks rapidly and
the blue IMU LED is solid. Note that when walk detect is active you will not be able
to move the arm using the IMUs, however, non-IMU controls will continue to
function as configured. If you are concerned about arm movement while walking (or
at other times) put the arm in Standby mode prior to walking.
When you stop walking and the IMUs come to rest, the arm reverts back to the
previous mode (Arm or Hand) the arm was in prior to entering walk detect and
resumes normal operation. This happens automatically when the IMU commands
return to zero. If the walk detect LED continues to blink, this indicates that the arm
is still receiving a command from one of your inputs. To resolve this issue, make
sure your IMUs are positioned correctly, your feet are flat/normal to the ground and
you are not activating any other inputs.
If you cannot resume normal operation of the arm and the white Arm Mode LED
continues blinking with your feet flat on the ground, the IMU zero point is incorrect
and the current signal level is above a set threshold. To fix this issue you need to
re-position the IMUs on your feet or zero the IMUs by going into Standby mode.
See Zeroing the IMUs.
IMU - Angle Limit Detect
The IMUs are designed to detect when you exceed the IMUs’ angle limit. This
occurs when you tip the IMUs more than 45 degrees since the last time the IMUs
were zeroed or were out of range. As a result, the white Arm Mode LED on the
Wrist Display blinks rapidly informing you of the problem.
If the IMUs exceed 45 degrees, you will not be able to move the arm with the IMUs,
however, non-IMU controls will continue to function as designed. To resume normal
operation you need to return your foot/feet to the rest or zero position.
If the white Arm Mode LED continues to blink, you need to reposition the IMUs,
re-position your feet, or zero the IMUs by going into Standby mode. See Zeroing
the IMUs.

Key Concepts
Mode Change Interlock
If you are in the process of switching modes (Standby to Hand mode or Hand to
Arm mode) and the system detects a command to move, the mode change
interlock becomes active. As a result, the white Arm Mode LED on the Wrist
Display blinks rapidly informing you of the problem.
You can switch modes when mode change interlock is active, however you will not
be able to command the arm. When the IMUs are returned to the zero position or
the wired input falls below the activation threshold you will be able to command the
arm.
If the problem does not clear automatically and the white Arm Mode LED continues
to blink, you need to re-position the IMUs/feet or zero the IMUs by going into
Standby mode (See Zeroing the IMUs) or you need to ensure the wired inputs are
not activated.
Zeroing the IMUs
Zeroing the IMUs establishes a neutral position. When you take the arm out of
Standby mode the system zeros the IMUs by taking a snapshot of the IMU’s
position and identifies that position as neutral. For example, if you should take the
arm out of Standby mode while your feet and attached IMUs are in an inclined
position the IMUs will be zeroed at that position. If you should then place your feet
and IMUs in a different position without zeroing the IMUs the result could be
unintended arm motion. To ensure this does not occur re-zero the IMU s by
performing the following steps:
1. Using the designated mode input place the arm in the Standby mode.
2. Place your feet at the position you want to zero the IMUs (usually feet flat on the
ground).
3. Using the designated mode input take the arm out of Standby mode.
4. The IMUs are now zeroed for that position and the IMU LED blinks blue once
every five (5) seconds.
If you have to continually re-zero the IMUs while not changing the neutral
position you should check to ensure the IMUs and shoe clips are securely
attached to your shoes.

Chapter 6: Charging the Batteries
Charging the IMU Battery
To charge the IMU battery you need to remove the IMU from its shoe mounting clip
and place the IMU on the charging pad. Note the following when charging the IMU
battery:
•
IMUs cannot be charged during use. The prosthesis stops functioning
and the System Fault Icon on the wrist display illuminates if this is
attempted.
•
Do not place any objects on the charging pad other than the IMUs.
•
Mobius Bionics suggests that you charge the IMU battery overnight.
•
The estimated time to recharge an empty IMU battery to 80% capacity is
less than 2.0 hours.
•
You can charge up to two IMUs at a time on the charging pad.
See Figure 43 to see how the IMU is placed on the charging pad and Table 17 for a
description of the IMU charging status LEDs.

Quality of Service Provisions
Any debris or clutter between the bottom of the IMU and the
Charging Pad may prevent IMU charging. Any increase in the
distance between the IMU and Charging Pad will increase
communication interference. This interference, however, will not
cause any incorrect data to be sent and will not cause any harm to
the LUKE arm system.
Loss or corruption of data between the IMU and Charging Pad for
more than 2 seconds can result in the interruption of charging.
In these cases, communication problems can usually be resolved by
ensuring the top of the Charging Pad is clean and clear of clutter,
the IMU is clean and its label is free of wrinkles, and that IMUs are
placed label side down and placed as close as possible to the center
of the charging pad targets.

Quality of Service Provisions
Interruption or corruption of communication between the Arm and
IMUs can lead to interruptions in arm motion. Interruption of
communication for more than 2 seconds may lead to the system
reverting to Standby mode. Interruption of communication for more
than 8 seconds results in the system declaring a fault.
Common consumer electronic devices that transmit in the same
frequency band used by the LUKE arm system may prevent the
Arm and IMUs from communicating. Microwave ovens, Bluetooth®
devices, Wi-Fi® networks and 2.4 GHz cordless phones, when
transmitting or receiving, can cause interruption of communication
between the Arm and IMUs. During testing, the LUKE arm system
experienced occasional communication interruptions in the
presence of Bluetooth mice. It is likely that other devices operating
in similar frequency ranges can have a similar effect. This
interference, however, will not cause any incorrect data to be sent
and will not cause any harm to the LUKE arm system.
Some metal detectors and anti-theft detection systems at store exits
transmit in the same frequency band used by the LUKE arm system.
These devices can cause interruption of communication between
the Arm and IMUs. Again, this interference will not cause any
incorrect data to be sent and will not cause any harm to the LUKE
arm system.
In each of these cases, communication problems can usually be
resolved by turning off or moving away from other RF transmitting
devices.

a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the LUKE arm system is used exceeds the applicable RF compliance level above, the LUKE arm system
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the LUKE arm system.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Overview
This chapter provides an overview defining the client needs as they relate to the
LUKE arm and system components in order to fit, set up, and configure the arm.
Topics in this chapter include:
•
The Client
•
LUKE Arm System
The Client
The first and foremost task in fitting, setting up, and configuring the arm is to meet
with the client and determine their needs as they relate to the LUKE arm. As each
client is different, you need to work with them to determine the appropriate arm
configuration and system components that best fit them. You need to determine
their physical and mental abilities as they relate to controlling and using the arm.
Once you have determined the arm configuration and system components, you
then need to examine the client and determine the type of socket and harness
needed to securely attach the arm to them.
Once you have determined the arm configuration and fabricated the socket and
harness, you need to determine the input control scheme for the client. Again, as
each client is different you need to work with them to determine the types of user
inputs they can use in the control scheme in order to control the arm.
Finally, you and/or a therapist should evaluate the strength and range of motion of
the client as related to their prosthetic arm treatment and, if indicated, prescribe a
home exercise program to address any limitations prior to the client engaging in
active use of the prosthesis. This program could include exercises to strengthen the
shoulder muscles including the rotator cuff, and the muscles of the upper arm if
indicated. It is suggested that the client advance their activities with the LUKE arm
on a gradual basis to minimize muscle soreness associated with using their new
prosthesis.

27
Chapter 1: Overview
This initial meeting with the client to clearly define their physical and mental ability,
the arm configuration, socket type and harness, user inputs, and to evaluate their
strength and range of motion is a critical first step in the setup and configuration of
the arm.
Indications For Use
The LUKE arm system consists of a prosthetic arm and accessories which are used
by a certified prosthetist to create a full upper extremity prosthesis indicated for
individuals, age 18 years and older, who have partial or full upper limb amputations
or congenital defects. The device is used to assist in activities of daily living (ADLs).
Contraindications For Use
The LUKE arm system may only be fit by an accredited prosthetist experienced in
the setup and configuration of powered prostheses.
The following list of contraindications is included to provide guidelines for client
evaluation/consideration. With clients having one or more of the conditions listed
below, further evaluation/consideration may be required. The client’s healthcare
providers should provide the final decision as to whether the client is suitable to use
the prosthesis. Some clients may require more extended training or a longer period
of time to adapt to using the device.
Areas to consider in the evaluation of prosthesis suitability or which may require
special consideration during the fitting of an arm system for a specific client include:
28
•
Skin conditions of their residuum such as burns, poor skin coverage, and severe
contractures that prevent current or prior wearing of a prosthetic arm.
•
Significant peripheral neuropathy, uncontrolled diabetes, inadequate extremity
sensory perception, severe phantom pain or a history of skin ulcers.
•
Significant comorbidities which in the opinion of the clinician would interfere
with the client’s ability to control the prosthesis.
•
Severe circulatory problems including peripheral vascular disease and pitting
edema.
•
Clients undergoing chronic renal dialysis with co-morbidities associated with
skin changes and poor wound healing deficits.
•
Communication deficits, neurocognitive deficits, or mental health problems that
would limit their ability to properly learn and control the prosthesis.
•
Significant uncorrectable visual deficits that would impair the ability to see
prosthesis movement, its controls or its indicators.

LUKE Arm System
Do not fit this system for a client unable to properly interpret your instructions or
the LUKE Arm User Guide. In addition, the anatomy of the individual’s residuum
may impact the suitability of the prosthesis, including excessive length – elbow
disarticulation, wrist disarticulation and partial hand amputations, or inadequate
residual limb length deficits may require further evaluation or special consideration.
LUKE Arm System
The LUKE arm is an upper-extremity prosthesis that accommodates Transradial
through interscapulothoracic (including Shoulder Disarticulation and short
Transhumeral) amputees. The arm provides a wide range of degrees of freedom and
several control options for controlling arm movement.
The LUKE arm is available in several different configurations and the system
components used to support the arm are dependent on the arm’s configuration.
One LUKE arm system may be used at a time by an individual.
For each arm that is to be fit on a client Mobius Bionics offers all the materials,
aside from 3rd party supplied input sensors, to configure the arm system. Materials
that are typically used to fabricate sockets and fit conventional prosthetics are not
supplied by Mobius Bionics.
Depending on the client’s arm configuration you will need to order certain
components from Mobius Bionics. Prior to setting up and configuring the arm you
should review and understand the components available from Mobius Bionics.
RISK OF DEATH OR SERIOUS HARM
Do not disassemble or modify any of the provided modules. Do not connect
any type of sensor not described in this guide without authorization of the
manufacturer. Please connect and configure the LUKE arm system per
instructions. Failure to do so could lead to injury.
The LUKE arm configurations and system components are described in the

Chapter 1: Overview
Arm Configurations
The arm is available in the three configurations listed below and shown in Figure 1.
Once you have determined which arm configuration best fits your client’s needs,
you need to specify if the arm is for the right or left side and the proper length as
well as which battery type will power the arm. For more information on arm
configurations and battery type used to power the arm see System Battery Types.
Shoulder Configuration (SC)
This arm is configured for those amputees with little or no residual limb or for those
amputees with limited movement or other restricting factors in their residual limb. In
most instances this arm configuration is powered by an internal battery located
inside the forearm of the arm and with an external battery used to supplement
power.
Humeral Configuration (HC)
This arm is configured for those amputees with a residual limb below the shoulder
but not including the elbow. In most instances this arm configuration is powered by
an internal battery located inside the forearm of the arm and with an external
battery used to supplement power.
Radial Configuration (RC)
The radial configuration is the shortest of the three configurations and is for
amputees with a residual limb below the elbow. Radial arm configurations are
powered by the external battery.

User Inputs/Outputs and the Control
Scheme
Prior to setting up and configuring the arm you need to determine which types of
user inputs the client can and will use to control the arm. To determine this control
scheme, you and the client need to decide which types of inputs the client can
physically operate in order to manage arm controls. This section provides
information on the arm controls as well as the types of user inputs used to control
the arm.
Topics in this chapter include:
•
Arm Controls — Switching vs. Motion
•
User Inputs
•
User Output - Tactor
Arm Controls — Switching vs. Motion
User inputs are used to select the two arm controls, switching and motion. You
need to identify and configure a specific user input to control switching of arm
operating modes while configuring the remaining user inputs to control hand and
arm motion.
Table 5 lists the arm controls and provides a description of the control.
Table 5.
Arm Controls
Arm Controls
Description
Switching
A user input used to change or toggle through the
operating modes: Standby mode, Hand mode, and
Arm mode (if available).
Motion
A user input used to vary the speed and position of a

Chapter 3: User Inputs/Outputs and the Control Scheme
User Inputs
Listed below are the user inputs used to control the arm. Following the list is a
description of each of the inputs, a description of how they are used, and any
restrictions when using the inputs.
•
IMUs (Inertial Measurement Units)
•
EMG - Electromyography (Surface EMG Electrodes)
•
Pressure Switches
•

IMUs (Inertial Measurement Units)
Description
IMUs command motion by having the client tilt their foot to control the configured
arm motions. See Figure 10.
The IMUs have an IP57 rating. The IP rating specifies the strength of an
enclosure against solids (such as dust) and liquids. An IP57 rating provides
resistance to water at depths up to 1 m (39 inches) and resistance to fine dust.

User Inputs
Places Used
Inertial Measurement Units (IMUs) are installed on top of client’s shoes using a shoe
clip or custom fabricated strap or pocket. For detailed information on installing and
setting up the IMUs see Chapter 8, “Installing IMUs”.
Arm Controls
IMUs are used to control arm motion and certain switching functions other than
mode select. See Restrictions below.
How They Are Used
If you intend to use IMUs, the first task you need to perform is to examine the
client’s feet and decide if they can be used for viable control inputs. The client has to
have the physical mobility to move their feet with enough dexterity to operate the
IMU.
The IMU designated for motion controls uses all four directions: anterior (toe),
posterior (heel), medial (inside), and lateral (outside). You and the client determine
which of these four motions are used to perform a specific arm motion. You
configure this using the Prosthetist Interface (PI). When configuring the IMUs using
the Prosthetist Interface you can adjust the output gains to vary the speed of the
arm’s motion.
The Prosthetist Interface allows you to configure up to two (2) sets of IMUs. The
client is able to switch between sets. This is useful when an IMU battery runs low;
the client can switch to the second set of IMUs while charging the first set. For
instructions on switching between IMUs, see Swapping IMUs.
The arm supports up to four IMU/ACI modules at a time in multiple
combinations, with a maximum of 2 IMUs. For example, you may set up and
configure the arm to support two IMU modules and two wired ACI modules or
four wired ACI modules and no IMUs.
Up to two pairs of IMUs can be assigned to an arm system, however only one
pair may be used at a time. See Swapping IMUs for more information about
switching between pairs of IMUs.
Restrictions
The IMUs CANNOT be used to control Switching (Mode Select) of the
arm. The system will not allow Mode Select to be assigned to an IMU input. This is
to eliminate the risk that the client can activate or deactivate the arm inadvertently
through the simple act of walking.

Installing IMUs
Once the ACI Modules have been installed and connected you can then install the
IMUs. The IMUs can be installed on a client's shoe or lower appendage using either
the shoe clips or an alternate means such as custom straps or pockets in the shoe.
There are two steps to install the IMUs on a shoe: attaching the shoe clip to the
client’s shoe and attaching the IMU to the shoe clip. If your client needs help putting
on and taking off the IMUs/shoe clips have the person who is providing the help
available at this time. IMUs can be installed on a lower appendage by alternate
means, as long as they are securely attached. If you create a label to indicate which
IMU your client uses on the left or right side or to designate IMU sets, avoid
covering the LED on the IMU.
The IMUs will not provide data if tipped more than 83 degrees. Be sure to
position the IMU as close to level as possible when installing the IMU. If you
mount the IMU at an angle of more than 38 degrees to begin, the IMU will not
provide the full range of +/- 45 degrees after zeroing because they are out of
range when they reach the 83 degree limit. See IMU - Angle Limit Detect.
Note that IMUs connect to the arm through a wireless connection. This wireless
connection is configured through software using the Prosthetists Interface. See
Chapter 11, “Configuring the Arm Using the Prosthetist Interface”.

Chapter 8: Installing IMUs
Installing the IMU/Shoe Clip on the Client’s Shoe
To install the shoe clip on client’s shoe, see Figure 66 and perform the following
steps:
•
Note that the shoe clip can be installed onto the shoe with the shoe on or
off the client’s foot.
•
Once the shoe clip is installed, the shoe clip can remain on the shoe.
•
If the IMU is in the clip, make sure to attach the clip and IMU to the
correct foot per the client's configuration.
1. Orient the shoe clip so that the open end of the clip is facing towards the client’s
toes.
2. Slide the shoe clip under the laces of the shoe.
When installing the shoe clip to the shoe, please ensure the following:
•
The shoe clip passes through at least two of the shoe’s laces to ensure the
clip is secure and stable.
•
The Front Arrow label on the bottom of the IMU is facing towards the
client’s toes. See Figure 65.
3. Tighten the laces to secure the IMU and shoe clip to the shoe.
4. If the client has not already done so, have them put on the shoe.

Waking a Sleeping IMU
The wireless IMUs do not contain an ON/OFF button. An IMU that is awake
and set up to communicate with an arm will do so once the arm is powered
ON. See Waking a Sleeping IMU and Initializing the Arm.
Waking a Sleeping IMU
When an IMU has not communicated with the arm for more than 30 minutes, the
IMU reverts to a sleep mode to conserve the battery. When in sleep mode the IMU
is not listening for arm communication.
As a result, if the IMU is in sleep mode when the arm is turned on, it will not
connect with the arm. This results in a sweeping pattern on the Grip Select LEDs
while the arm tries to connect with the IMUs. If the arm doesn’t connect with the
IMUs after about 10 seconds, an “IMU Comm Lost” fault will occur. Having the
client shake their foot with the IMU attached wakes the IMU from sleep mode so
that the IMU is ready to communicate with the arm once the arm system is powered
on. See Swapping IMUs for details on switching between sets of IMUs or
Troubleshooting the Arm for troubleshooting information.
An IMU that has been shaken awake is waiting to communicate with the arm. IMUs
that are not actively communicating with an arm blink the battery state of charge
LED whenever they are shaken, regardless of whether they are sleeping or not.
After shaking the IMU awake if it does not communicate with the arm within
five (5) minutes the IMU reverts back to sleep mode to conserve the battery
charge.

Chapter 11: Configuring the Arm Using the Prosthetist Interface
Understanding Thresholds and Gains
Thresholds and gains are two terms used in configuring the arm. These terms are
described below.
Thresholds
A threshold is the signal level which specifies the point at which the signal
commanded by the client is translated into motion or switching command by the
arm. Upper and Lower Thresholds in the PI are represented by a pair of horizontal
bars on the vertical scale in the configuration screen.
Gains
Gain is the amplification or scaling factor of the input signal. Gain is calculated as
the ratio of output over input. When you adjust the gain using the gain dial, you are
changing how the arm responds to a user input signal.
Setting Joint or Motion Speed Limits
When setting joint or motion speed limits you need to note the following:
190
•
Mobius Bionics recommends that clients NOT watch the Prosthetist Interface
configuration screens while configuring the arm. Allowing the client to watch
the screens prompts them to respond to the signal level intensity by visual
response. This can interfere with the clients response of inputs to outputs and
affect their comfortable exertion levels.

Setting Joint or Motion Speed Limits
Input Gains
When setting Input Gains note the following:
•
Mobius Bionics recommends an IMU range of motion of +/- 35 degrees from
zero reference. Note that any client inputs above 45 degrees will be ignored.
•
Set input gains based on comfortable exertion levels.
•
The input gains should be adjusted so that the client can reach 100% input
signal at comfortable exertion levels.
Performing the steps above for Input Gains caps the maximum input signal at
these exertion levels.
Input Thresholds
When setting Input Thresholds note the following:
•
Start with an input threshold setting of 15 to 20 above the resting signal level
when the axes are configured independent or coupled.
•
Only decrease these settings as the client develops proficiency in using the arm.
Output Gains
The output signal level represents a fraction of the maximum joint speed the client is
allowed to use. The output gain is the final control you should use to define the
output speed.
When setting Output Gains note the following:
•
Adjust the output gains so that the output signal at the client’s comfortable
maximum exertion level produces the desired joint or motion output speed.
•
Mobius Bionics recommends starting with an output signal level of 30 to 50%.
•
Only increase these settings as the client develops proficiency in using the arm.

Chapter 11: Configuring the Arm Using the Prosthetist Interface
Step 4: Configure Inputs
To configure the IMUs you must select the Activation Channel and set the
Thresholds and Gains for the left IMU anterior/posterior, left IMU medial/lateral,
right IMU anterior/posterior, and right IMU medial/lateral. If you have configured
the client’s system to have two sets of IMUs, these settings will apply to both sets.
Prior to configuring the inputs you need to verify that the input signals are
functioning properly by viewing the View Input Signals screen. See Viewing
Input Signals.
To configure the IMUs perform the following steps:
1. In the PI main screen click the Step 4: Configure IMUs button.
The IMU Setup screen opens. See Figure 125 and Table 24 for more
information.

Description
The type of input used to control the arm.
The selections on the screen are:
• IMU
• Rate Sensitive
• Pattern Recognition
NOTE: Selections that are not available are grayed
out.
Activate/Zero IMUs
Activates and zeros the IMUs.
Independent
Allows output of only the intended command axes
with the greater signal intensity on an IMU.
Coupled
Allows for simultaneous output of both axes of an
IMU.
Walk Detect
Enables (active) or disables (inactive) walk detect. Walk
detect ignores commands from the IMU when the
client is walking.
2. Select the corresponding motion for the correct IMU as indicated in the IMU
Setup screen.
The input level should hover or “zero” somewhere around the midpoint of the
scale. If it does not, perform the following to “re-zero” the IMUs:
a. Have the client stand with the IMUs in the desired zero position (usually feet
flat on the floor).
b. Press the Activate/Zero IMUs button. See Figure 126.

Chapter 11: Configuring the Arm Using the Prosthetist Interface
Figure 126. Activate/Zero IMUs
The client should be standing during IMU configuration as there is less
freedom of movement when the client is bearing weight on their feet.
3. Communicate and demonstrate to your client that the IMUs, mounted on each
foot, function by measuring the pitch (anterior/posterior movements) and roll
(medial/lateral movements) of the client’s foot.
4. Configure the Upper and Lower Gains for the Left IMU.
Adjust the Upper and Lower Gain dials so that full signal is displayed on the bar
graph when the client pitches and rolls the IMU at a comfortable maximum
position.
5. Configure the Thresholds for the left IMU.
Start with an input threshold setting of 15 to 20 above the resting signal level
and the IMU axes configured to coupled.
When configuring Thresholds in a coupled configuration the goal is to set
thresholds to prevent unintended crosstalk of pitch and roll commands while
making the activation range as symmetrical as possible in the coupled
movement directions (anterior/posterior and medial/lateral). This is
accomplished by:
a. Setting the Anterior and Posterior Thresholds such that Medial and Lateral
movements do not cause the Anterior/Posterior signal level to cross the
thresholds and cause unintended motions.
194
Use or Disclosure of Data Contained on this Page is Subject to the Copyright Restrictions on the Inside Title Page of this Document -- Rev. 1.5
Step 4: Configure Inputs
b. Setting the Medial and Lateral Thresholds such that Anterior and Posterior
movements do not cause the Medial/Lateral signal level to cross the
threshold and cause unintended motions.
c. Setting the Thresholds by entering the threshold value in the threshold box
or by dragging the corresponding threshold sliders.
6. Repeat Steps 4 and 5 for the Right IMU.
7. If the client is unable to independently actuate each motion of the IMU with
modest thresholds, the independent option for the IMU axes should be selected.
This allows for command of one axis at a time. If the independent option is
selected repeat steps 1 through 7 above.
8. Click the Update Arm button.
If, after configuring the action (STEP 5 in the configuration process), the arm
moves due to crosstalk of the pitch and roll commands, check that the IMUs
are properly positioned then increase the Threshold until the unintended
motion stops. As an alternative, selecting the independent option allows for
command of only one axis at a time.

the action.
Configuration Screens - Arm Actions
When you click the Configure Action button the configuration screen for the
selected arm action is displayed. The configuration screen sets the threshold and
gain and is similar to the process performed in STEP 4. See Figure 128 and
Table 26 for more information.
You may need to work through the configuration process with the client a
couple of times to let them experiment with different configurations until they
settle on one setup that is intuitive and is most easily controlled.
When you select an IMU for a particular action, changing the input gains and
thresholds requires returning to the IMU configuration. See Step 4: Configure
Inputs. If, after configuring the action, the arm moves due to crosstalk of the
pitch and roll commands, the thresholds should be increased until the
unintended motion stops.

Description
Input Gain
For Single Site and Dual Site inputs, this should be
adjusted so that the client can reach 100% input
signal at a comfortable exertion level.
Threshold Value
Input signals below this level are ignored by the
system.
Select Activation Mode
(Single Site only)
This parameter selects how the system reacts to
command signals when the system transitions from
Standby to Hand or Arm (if applicable) modes. The
Active Zero option allows you to set a “zero” point at
a selected level of the input signal. Changes relative to
the “zero” of the input signal are treated as command
inputs. The Conventional option turns off this feature
in single site inputs.
Active Zero is built into IMU input functions, and can
be selected for Single Site inputs, but not Dual Site
inputs. Note that the Active Zero function of the IMUs
cannot be shut off.
Output Gain
Allows you to increase or decrease the amount of
output gain in order to achieve an ideal response after
you have properly set up the input gains. This
effectively sets the velocity response of the joint being
configured.
Switch Direction
Allows you to change the direction of movement that
occurs when an input is active.
Velocity Control
Allows you to configure the controls in velocity mode
where the velocity of the joint is controlled based on
how hard the client presses on the sensor. This
control is similar to using a joystick.
Position Control
Allows you to configure the controls in position mode
where the joint is controlled to a desired position
commanded by the client. This control is similar to
using a mouse or a touchpad.
Go to each appropriate Action and configure settings according to what the client
wants (the process is similar to the steps used in Step 4). You may go through this
process a couple of times to let the client experiment with different configurations
until they settle on one setup that is intuitive to them and is most easily controlled.

Quality of Service Provisions
Any debris or clutter between the bottom of the IMU and the
Charging Pad may prevent IMU charging. Any increase in the
distance between the IMU and Charging Pad will increase
communication interference. This interference, however, will not
cause any incorrect data to be sent and will not cause any harm to
the LUKE arm system.
Loss or corruption of data between the IMU and Charging Pad for
more than 2 seconds can result in the interruption of charging.
In these cases, communication problems can usually be resolved by
ensuring the top of the Charging Pad is clean and clear of clutter,
the IMU is clean and its label is free of wrinkles, and that IMUs are
placed label side down and placed as close as possible to the center
of the charging pad targets.

Arm Radio Specifications (Continued)
Parameter
Quality of Service Provisions
Range/Explanation
Interruption or corruption of communication between the Arm and
IMUs can lead to interruptions in arm motion. Interruption of
communication for more than 2 seconds may lead to the system
reverting to Standby mode. Interruption of communication for more
than 8 seconds results in the system declaring a fault.
Common consumer electronic devices that transmit in the same
frequency band used by the LUKE arm system may prevent the
Arm and IMUs from communicating. Microwave ovens, Bluetooth®
devices, Wi-Fi® networks and 2.4 GHz cordless phones, when
transmitting or receiving, can cause interruption of communication
between the Arm and IMUs. During testing, the LUKE arm system
experienced occasional communication interruptions in the
presence of Bluetooth mice. It is likely that other devices operating
in similar frequency ranges can have a similar effect. This
interference, however, will not cause any incorrect data to be sent
and will not cause any harm to the LUKE arm system.
Some metal detectors and anti-theft detection systems at store exits
transmit in the same frequency band used by the LUKE arm system.
These devices can cause interruption of communication between
the Arm and IMUs. Again, this interference will not cause any
incorrect data to be sent and will not cause any harm to the LUKE
arm system.
In each of these cases, communication problems can usually be
resolved by turning off or moving away from other RF transmitting
devices.

electromagnetic site survey should be considered. If the measured field strength in the location in which
the LUKE arm system is used exceeds the applicable RF compliance level above, the LUKE arm system
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the LUKE arm system.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P
is the maximum output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE 1: At 80 MHz, 460 MHz, 470 MHz, 690 MHz, 800 MHz, 965 MHz, and 1.39 GHz, the
separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
