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.

Robotiq Hand-E Gripper - Instruction Manual

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.

0x1 - 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 rACT bit 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.
l

0x0 - Stop.

0x1 - 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).
l

0x0 - Normal.

0x1 - Emergency auto-release.
Caution

Robotiq Hand-E Gripper - Instruction Manual

0x03 - Fingers are at requested position. No object detected or object has been loss / dropped.
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

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).
l

This feature is automatically set according to the force request rFR.
Info
Feature is off at force request rFR = 0, otherwise it is on.

Re-grasp will keep the position setting:
l

Finger motion will stop when rPR position is reached, even if there is no object.

Force 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.

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.
l

0x00 - Fingers are in motion towards requested position. No object detected.

0x01 - Fingers have stopped due to a contact while opening before requested position. Object detected.

0x02 - Fingers have stopped due to a contact while closing before requested position. Object detected.

0x03 - 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.

4.6. Control Logic Example

Fig. 4-2: Example of Gripper control logic with corresponding registers.

Robotiq Hand-E Gripper - Instruction Manual

4.7. Modbus RTU Communication
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.

Modbus register(0x07D0) is composed from the first 2 Robotiq 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.

Robotiq Hand-E Gripper - Instruction Manual

4.8. Control over Universal Robots with URCaps
The URCap package contains many features to program and control the Gripper. The package provides:
l

Gripper toolbar: The Gripper toolbar is automatically installed with the URCaps package. It allows jogging and testing of the Gripper. It is a great tool to try grasps with the Gripper while programming.
Gripper node: The URCaps package adds a Gripper node that is used to add a Gripper command. A node can make the Gripper
move to a specific opening, grasp an object and modify the speed and force applied by the Gripper.
Caution
Starting from Gripper URCap version 1.0.2, the gripper activation script command (rq_activate() or rq_activate_and_wait())
must be preceded by the reset command (rq_reset()). This will force the gripper's activation routine. Thus, if the gripper was
already activated, it will activate again.

Info
The Gripper needs to be activated before it can receive a command. To do so, use the rq_activate_and_wait() function script
at the beginning of the program or activate with the Gripper toolbar. Starting from Gripper URCap version 1.0.2, the Gripper
activation script command (rq_activate() or rq_activate_and_wait()) must be preceded by the reset command (rq_reset()). This
will force the Gripper's activation routine. Thus, if the Gripper was already activated, it will activate again.

Command window
The Command window shows the requested action parameters for the Gripper node. Depending on the position, speed and force
parameters, warning messages may display.
To edit the Gripper node, tap Edit action (please refer to the Edit action screen section for more details).

Edit action screen
Tap Edit action from the Command window and use the Edit action screen to edit the Gripper’s parameters and adjust its position,
speed and force. In normal usage conditions, the Gripper will move as soon as you change the position setting. The Gripper will not
move if it is not properly powered, connected and activated.
Caution
The Gripper needs to be activated before it can receive a command. To do so, use the rq_activate_and_wait() function script
at the beginning of the program or activate with the Gripper toolbar. Starting from Gripper URCap version 1.0.2, the gripper
activation script command (rq_activate() or rq_activate_and_wait()) must be preceded by the reset command (rq_reset()). This
will force the gripper's activation routine. Thus, if the gripper was already activated, it will activate again.

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
following modifications:
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:
l

rq_print_fault_code -> rq_print_gripper_fault_code

rq_print_num_cycles -> rq_print_gripper_num_cycles

rq_print_driver_state -> rq_print_gripper_driver_state

rq_print_firmware_version -> rq_print_gripper_firmware_version

rq_print_driver_version -> rq_print_gripper_driver_version

Robotiq Hand-E Gripper - Instruction Manual

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 :
l

Assign initial values to the global variables in the Init Variables section.

Initiate the communication with the Gripper in the BeforeStart section.

The Robot Program section contains the commands sent to the Gripper:
l

Activate 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.

Move 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.

Close the Gripper with rq_close_and_wait.

Watch for object detection status:
l

If an object is detected, the script moves the robot and opens the Gripper.

If 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

105

4.9.3. Custom Programs
You can create your own program that commands the Gripper with the provided templates :
l

Open basic_template.script in the list of provided templates;

Push play to test the Gripper. The program will activate the Gripper and then do a loop of closing and opening the Gripper;

Add 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:
l

Assign initial values to the global variables with the Init Variables section.

Initiate communication with the Gripper with the Before Start section.

The Robot Program section contains the commands sent to the Gripper:
l

Activate the Gripper with SubP_rq_activate_and_wait.

Close the Gripper with rq_close_and_wait.

Open 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.

Robotiq Hand-E Gripper - Instruction Manual

4.9.4. Provided Variables and Functions
The file rq_script.script contains function definitions and variables that enhance the programming of the Gripper. Here is the list of
these variables and functions.

6.1.2. Fingers and fingertips
The contact grip points for Hand-E are its two fingertip pads.
Fingertip options are supplied by Robotiq (please refer to the Spare Parts, Kits and Accessories section). Users can create their own
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:
l

Forces 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.

Refer to Mechanical specifications section to evaluate the grip force according to your fingertip design.
Info
You can install custom fingertips directly on the rack or on the fingertip holder.
Tip
Fingertips can be mounted directly on the racks or on fingertip holders.

Payload and force
Actuation force model used to calculate the recommended friction payload (W):

where:
l

F is the force that is applied to the load by the Gripper.

Cf is the friction coefficient between the fingertip and the part load.

Sf 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
l

The Actuation Force is the force that can be applied to an object by the motor of the Gripper.

The 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.
