4. Control
Info
Unless specified, all values in this section are in hexadecimal values.
4.1. Overview
The Robotiq Hand-E Gripper is controlled directly via Modbus RTU using a RS485 signal. It can also be controlled via an optional
Robotiq Universal Controller using an industrial protocol (refer to the instruction manual of the Robotiq Universal controller). The
programming of the Gripper can be done with the Teach Pendant of the robot or by offline programming. The communication method
used to control the Hand-E Gripper does not change the control logic or register setups described in the following subsections.
Tip
Robotiq suggests using the Robotiq User Interface test software to explore the various features of the Gripper, like object
detection and forcecontrol.
Since the Robotiq Hand-E Gripper has its own embedded controller, high-level commands, such as "Go to requested position" are
used to control it.
Info
The operator can:
- Control force, speed and position of the Gripper fingers.
- Finger movement is always synchronized, movement is initiated via a single "Go to requested position"command.
- Parallel or encompassing grip is performed automatically.
- A built-in object detection feature is available; the user can be notified after an object is picked once the "Go to" command
has been initiated. The feature also works for lost or dropped objects, and the user can be alerted if an object is dropped
after being detected.
- Engage directional (open or close) auto-release for emergencies.
Control using registers
The Gripper has an internal memory that is shared with the robot controller. One part of the memory is for the robot output; gripper
functionalities. The other part of the memory is for the robot input; gripper status. Two types of actions can then be performed by the
robot controller :
1. Write in the robot output registers to activate functionalities;
2. Read in the robot input registers to get the status of the Gripper.
The Gripper Register Mapping section will map the different registers used to control the Gripper or to read its status while theRobot
Output Registers &Functionalities section will detail the output (write) register functions, and the Robot Input Registers &Status section
will detail the input (read) register status. The figure below is a representation of the memory and the control logic of the Gripper.

Fig. 4-1: Hand-E control logic overview
Control using Universal Robots packages
Robotiq provide Universal Robots packages to be used with URCaps (require controller CB3 or higher)
Please refer to the Control section for instructions on how to use the Gripper URCap; this method will provide you with a Gripper
Toolbar to test and a Gripper node to program via the URCaps tab.
Please refer to the Control over Universal Robots without URCaps section on how to use without URcaps, this method will provide you
with a similar Gripper Toolbar but the robot program will be built using subprograms and scripts.

any fault status.
l0x0 - Deactivate Gripper.
l0x1 - Activate Gripper (must stay on after activation routine is completed).
Warning
When setting rACT (rACT ==1), the Gripper will begin movement to complete its activation feature.
Info
Power loss will set rACT (rACT == 1); the rACTbit must then be cleared (rACT == 0), then set again to allow operation of the
Gripper.
Caution
The rACT bit must stay on afterwards for any other action to be performed.
rGTO
The "Go To" action moves the Gripper fingers to the requested position using the configuration defined by the other registers, rGTO
will engage motion while bytes 3, 4 and 5 will determine aimed position, force and speed. The only motions performed without the
rGTO bit are activation and automatic release routines.
l0x0 - Stop.
l0x1 - Go to requested position.
rATR
Automatic Release routine action slowly opens the Gripper fingers until all motion axes reach their mechanical limits. After all motions
are completed, the Gripper sends a fault signal and needs to be reinitialized before any other motion is performed. The rATR bit
overrides all other commands excluding the activation bit (rACT).
l0x0 - Normal.
l0x1 - Emergency auto-release.
Caution
43
Robotiq Hand-E Gripper - Instruction Manual
The automatic release is meant to disengage the Gripper after an emergency stop of the robot.
The automatic release is not intended to be used under normal operating conditions.
Automatic release requires the rACT to be cleared (rACT == 0) then set (rACT == 1).
44

Caution
In some circumstances the object detection feature may not detect an object even if it is successfully grasped. For instance,
picking up a thin object may be successful without the object detection status being triggered. In such applications, the
"Fingers are at requested position" status of register gOBJ is sufficient to proceed to the next step of the routine.
Tip
47
Robotiq Hand-E Gripper - Instruction Manual
Checking for the correct position of the fingers (byte 4), as well as object detection (byte 0, bit 6 & 7) before proceeding to the

4.5. Picking Features
As stated in previous sections, object picking is done via a simple "Go To" command, rGTO bit calls for movement, while rPR byte is
the aimed position, rSP and rFR will be the desired speed and force settings respectively. This section describes key features in object
picking applications:
lForce control
lRe-grasp
lObject detection
lObject contact loss
4.5.1. Force control
The gripping force is controlled via the rFR byte (please refer to the Robot Output Registers &Functionalities section).The Gripper
behavior will change according to the rFR forcerequested.
lrFR = 0 : Very fragile objects or deformable objects mode
lLowest force
lRe-grasp feature is off
l1rFR 255 : Solid & firm objects
lHigh torque mode
lRe-grasp feature is on
50

Coming soon
Measured grip force for silicone of specific hardness (Durometer)
Coming soon
4.5.2. Re-Grasp
Re-grasp feature is a built-in feature meant to prevent object lost due to slipping or inaccurate initial grip. The Re-grasp feature will
allow the Gripper to initiate a movement when an object is slipping or dropped. When Re-grasping, the Gripper will attempt to close
until it reaches the position request (rPR).
lThis feature is automatically set according to the force request rFR.
Info
Feature is off at force request rFR = 0, otherwise it is on.
lRe-grasp will keep the position setting:
lFinger motion will stop when rPR position is reached, even if there is no object.
lForce and speed settings are not used, Re-grasp force and speed will automatically adjust to keep the object from being lost /
dropped.
Info
While your initial settings for force and speed are not used for Re-grasp, they will never be eceeded to prevent damaging the
part.
Caution
The rOBJ status is cleared when a motion is detected.
51
Robotiq Hand-E Gripper - Instruction Manual
4.5.3. Object detection
When the Gripper grabs an object, the gOBJ status will allow you to know if contact with the object was successful. This is a built-in
feature for adaptive grippers meant to be used by the robot controller (or PLC) commanding the overall application. The Object
detection feature will change the gOBJ status and can be used inside your robot program.
As stated in the previous section:
gOBJ: Only valid if gGTO = 1.
l0x00 - Fingers are in motion towards requested position. No object detected.
l0x01 - Fingers have stopped due to a contact while opening before requested position. Object detected.
l0x02 - Fingers have stopped due to a contact while closing before requested position. Object detected.
l0x03 - Fingers are at requested position. No object detected or object has been lost / dropped.
Example of contact detected with an object:
1. Set position, speed and force at maximum (full closing):
a. rPR == 0xFF, rSP == 0xFF, rFR ==0xFF,
2. Set ''go to requested'' will initiate movement :
a. rGTO == 0x01
3. Then object detection status will be "in motion"
a. gOBJ == 0x00
4. Until an object is picked, object detection status will then be "stopped due to contact while closing"
a. gOBJ == 0x02
5. The user can now assume it is holding the payload, and proceed to the next step.
Example of contact lost with an object:
1. From the previous example, after an object is picked
a. gOBJ == 0x02
2. If the gOBJ status displays 0x03 after it was 0x02, user can assume contact with the object has been lost.
4.5.4. Brake engagement
The Hand-E Gripper is equipped with a brake that engages at the end of each and every Gripper move, and thus disengages between
each of these moves.
For instance, when fully closing on an object, the Gripper makes contact with the surface of the object and activates the brake before
sending the object detection signal to the robot.

Robotiq Hand-E Gripper - Instruction Manual
4.7. Modbus RTUCommunication
The Gripper can be controlled by Modbus RTU directly with RS485 or over USB using the ACC-ADT-USB-RS485. This section is
intended to provide guidelines for setting up a Modbus master that will adequately communicate with the Gripper.
For a general introduction to Modbus RTU and for details regarding the CRC algorithm, the reader is invited to read the Modbus over
serial line specification and implementation guide available at: http://www.modbus.org/docs/Modbus_over_serial_line_V1_02.pdf.
For debugging purposes, the reader is also invited to download one of many free Modbus scanners such as the CAS Modbus Scanner
from Chipkin Automation Systems available at: http://www.store.chipkin.com/products/tools/cas-modbus-scanner.
Info
Modbus RTU is a communication protocol based on a Big Endian byte order. Therefore, the 16-bit register addresses are
transmitted with the most significant byte first. However, the data port is in the case of Robotiq products based on the Little
Endian byte order. As such, the data parts of Modbus RTU messages are sent with the less significant byte first.
Tip
Modbus RTUspecifications and details can be found at www.modbus.org.

Each register (word - 16 bits) of the Modbus RTU protocol is composed of 2bytes (8 bits) from the Gripper. The first Gripper output
Modbus register(0x07D0) is composed from the first 2Robotiq Gripper bytes (byte 0 and byte 1).
Info
200 Hz is the maximum speed when commanding / reading from the Robotiq Gripper. It is therefore recommended to send
commands with a minimum delay of 5 ms between them.
Info
120 Ohms termination resistor is already present on the converter and the Gripper. If multiple grippers are connected in
parallel on the same RS485 cable, termination resistor must be set to OFF in communication parameters.

4.8.5. Retro-compatibility of URCaps with legacy driver programs
The Gripper URCap can be used within programs that were made with the legacy driver package. To do so, you need to do the
followingmodifications:
1. Open your .urp program in PolyScope and execute it.
a. You should see an error message that tells you that some functions are double defined. This is because the URCap
embeds the functions directly in the program preamble, so there is no need for a BeforeStart section.
2. Comment all the lines of the BeforeStart section from your older .urp program.
a. You will still get an error. It arises because we changed some functions names due to a naming conflict.
3. To solve the problem, you can either suppress those functions or rename them.
Since they are probably not used in a production program, the fastest would be to suppress them, as shown in the figure
below.
Fig. 4-15: Older program's subprograms to suppress or rename to use with URCaps package.
Here is the list of the functions that were renamed:
lrq_print_fault_code -> rq_print_gripper_fault_code
lrq_print_num_cycles -> rq_print_gripper_num_cycles
lrq_print_driver_state -> rq_print_gripper_driver_state
lrq_print_firmware_version -> rq_print_gripper_firmware_version
lrq_print_driver_version -> rq_print_gripper_driver_version

4.9. Control over Universal Robots without URCaps
If your Universal Robots controller is not compatible with the URCap package (see Installation for Universal Robots section) for
compatibility), you can install the driver package. This package allows programming of the Gripper with scripts in a PolyScope
program. It includes program templates and examples to help you get started with your own custom program. It also contains the
Gripper toolbar for jogging and controlling the Gripper.
4.9.1. Gripper Toolbar
Overview
The Gripper toolbar is automatically installed with the driver package. The Gripper toolbar allows you to jog and test the Gripper. It is a
great tool to try grasps with the Gripper while programming.

Info
The driver state "RQ_STATE_INIT" means the driver is attempting to connect to a Robotiq Gripper. When connection is
established, the normal toolbar detailed above will appear.
Tip
If you see the following toolbar with communication not established, check if your Gripper is powered first, then check if the
RS-485 to USB converter is properly wired.

Robotiq Hand-E Gripper - Instruction Manual
4.9.2. Demo Scripts
The following section details the demo scripts provided with the driver package.
pick_and_place_demo_with_subprograms.script is a demo script for pick and place applications using provided subprograms. The
script uses subprograms included in the package such as rq_set_force, rq_set_speed, etc.
Info
All provided subprograms are identified with the prefix rq_.
The script uses rq_speed and rq_force as speed and force parameters to be used during the program. They can be modified using
values from 0 to 255 (please refer to the Provided Variables and Functions section).
The script executes the following actions in sequence :
lAssign initial values to the global variables in the Init Variables section.
lInitiate the communication with the Gripper in the BeforeStart section.
lThe Robot Program section contains the commands sent to the Gripper:
lActivate the Gripper with SubP_rq_activate_and_wait.
Info
Remember that all _and_wait subprograms will wait for the action to be completed before going to the next step.
lMove the robot to a predetermined position
Tip
Run with Universal Robots simulator first or make sure that the UR robot work area is totally cleared before running the
script, as it will move therobot.
lClose the Gripper with rq_close_and_wait.
lWatch for object detection status:
lIf an object is detected, the script moves the robot and opens the Gripper.
lIf no object is detected, the script prompts a warning
.pick_and_place_demo_async_partial_opening_without_subprograms.script is similar to the previous demo, but without using
subprograms. This demo uses asynchronous commands so that the robot and the Gripper will move at the same time (the previous
example had the Gripper and the robot move separately).
Robotiq Hand-E Gripper - Instruction Manual
4.9.3. Custom Programs
You can create your own program that commands the Gripper with the provided templates :
lOpen basic_template.script in the list of provided templates;
lPush play to test the Gripper. The program will activate the Gripper and then do a loop of closing and opening the Gripper;
lAdd your instructions under the robot program section. Program instructions can be added with PolyScope.
When programming an object pick up, use the rq_is_object_detected subprogram and rq_object_detect variable to know if
an object has been picked. The subprogram sets the rq_object_detect variable to 1 if an object is detected, 0 otherwise.
Subprograms with the _and_wait will wait for the instruction to be completed before going to the next step. For example, rq_
close_and_wait will wait for the motion to be completed before continuing to the next step, while rq_close will initiate motion
and go to the next programmed step.
As shown in the figure below, the basic_template program will execute these instructions in a sequence:
lAssign initial values to the global variables with the Init Variables section.
lInitiate communication with the Gripper with the Before Start section.
lThe Robot Program section contains the commands sent to the Gripper:
lActivate the Gripper with SubP_rq_activate_and_wait.
lClose the Gripper with rq_close_and_wait.
lOpen the Gripper with rq_open_and_wait.
Fig. 4-17: Basic template as shown in UR PolyScope.
When using the advanced_template, you have access to all of the subprograms listed in the Provided Variables and Functions section.
Unused subprograms can be removed from the list. You must use global variables to pass information, not arguments.

fingertips from scratch. The figure below represents the fingertip holder, the permanent, non customizable part of the Gripper finger on
which the fingertip must be mounted.
Custom fingertip design must meet the following specifications:
lForces exerted at the end of the fingertips must not exceed 100 N , regardless of the direction. Please refer to the Moment and force
limits section for more details.
Warning
The following limits must be respected at all times.
Calculation of maximum moment and force should include robot acceleration and safety factors.
lRefer to Mechanical specifications section to evaluate the grip force according to your fingertip design.

Robotiq Hand-E Gripper - Instruction Manual
Payload and force
Actuation force model used to calculate the recommended friction payload (W):
where:
lFis the force that is applied to the load by the Gripper.
lCf is the friction coefficient between the fingertip and the part load.
lSf is a safety factor to be determined by the robot integrator.
Fig. 6-15: Actuation force on the fingertip of the Hand-E Gripper
Info
lThe Actuation Force is the force that can be applied to an object by the motor of the Gripper.
lThe Gripper has a power off brake. This means that when no power goes to the Gripper, the fingers are blocked.
Info
For example, if the silicone fingertips (HND-TIP-SLC-KIT) are used to lift a lubricated steel part (machine tending with cutting
oils), the friction coefficient would be 0.3 (tested static coefficient of friction).
Maximum weight with a safety factor of 2.4 and maximum force would be:
W = (2 x 130 N x 0.3) / 2.4 = 32.5 N
This calculation means that a 3.3 kg part will be held by the Gripper when not moving (standing still). When accelerating, the
payload will decrease.
The biggest factor in such calculations will always be the friction coefficient, we recommend testing the coefficient.
Warning
You must consider the robot acceleration in your payload calculations.
Robot emergency stops will lead to major deceleration velocities.
