Python Driver for Robotiq Grippers.

PyRobotiqGripper Logo

Python Driver for Robotiq Grippers.

pyRobotiqGripper is a Python library designed to facilitate control of Robotiq grippers using Modbus RTU communication via serial port or over ethernet. It is compatible with 2F85, 2F140, and Hande.

Documentation: pyRobotiqGripper Documentation

1. Disclaimer

This library can be seen as a starting point for a Robotiq integration project. You are responsible for what you do with this library. The author takes no responsibility for any malfunction.

Warning This library is not maintained by Robotiq.

2. How to Install

Install the pyRobotiqGripper python package using PIP.

python3 -m pip install "pyRobotiqGripper[all]"

The all extra includes the optional dependencies used by the joystick CLI and history/data helper methods.

Note The way python is called (python3 vs python) may depend on your system configuration. If the above command does not work, try replacing python3 with python.

3. Typical Usage

3.1 Robotiq gripper connected at PC USB port via a USB to RS485 converter

import pyrobotiqgripper as rq

#Create a Robotiq gripper object.
gripper = rq.RobotiqGripper()

By default, the serial port on which the gripper is connected is automatically detected. However, you can manually specify the serial port name if you want to. Refer to the API documentation for more information.

3.2 Robotiq gripper connected to a UR robot with RS485 URCAP installed

Replace <UR_ROBOT_IP> with the actual IP address of your UR robot.

import pyrobotiqgripper as rq

#Create a Robotiq gripper object.
gripper = rq.RobotiqGripper(connection_type="RTU_VIA_TCP", tcp_host=<UR_ROBOT_IP>)

3.3 Gripper control

Activate the gripper and do whatever you want with the gripper: open, close, get position feedback, etc.

gripper.activate()
gripper.calibrate(closemm=0, openmm=40)
gripper.open()
gripper.close()
gripper.move(100)
position_in_bit = gripper.position()
print(position_in_bit)
gripper.move_mm(25)
position_in_mm = gripper.positionmm()
print(position_in_mm)

Note: During activation, the gripper is going to fully open and close. Do not disturb this process. Do not place an object inside the gripper.

Note: Position, Speed and Force varie from 0 to 255. It is coded on 8 bits.

You can print the current status of gripper registers using printStatus().

gripper.printStatus()

For realtime control use the realTimeMove method.

gripper.realTimeMove(requestedPosition=100)

The realTimeMove method is designed to be called in a loop with a high frequency. It will move the gripper to the requested position with a speed that depends on the distance to the target position. This allows for a smooth and responsive control of the gripper.

4. Joystick CLI Feature

pyRobotiqGripper includes a command-line interface (CLI) tool for controlling the gripper using a joystick or gamepad.

This CLI requires the all extra.

To use the Joystick CLI, run:

pyrobotiqgripper-joystick

You can also check the available options:

pyrobotiqgripper-joystick --help
