     git clone --recurse-submodules git@git.cps.unileoben.ac.at:Niko/UR_Robotiq.git 
     

How to Start the Docker Compose

1. Prerequisites

   • Ensure you have Docker and Docker Compose installed on your system (Instructions can be found on the official Docker website: https://www.docker.com/)

2. Starting the Containers

   • Navigate to the project directory in your terminal:

      cd UR-Robotiq 
     

   • Run the following command to start the Docker Compose:

     docker compose up -d 
     

   • Give X11 permission to accept the stream of the container window:

     xhost +
     

   • Get the name of the container:

     docker ps
     

   • Access the terminal of the docker container

     docker exec -it <name of docker container> /bin/bash
     

Working with UR + Robotiq

In general you need to start up the UR Robotiq Controller, here the robot_ip has to be defined and if you want to start up the real robot or use fake hardware and if you want to launch rviz!

ros2 launch ur_robotiq_description ur_robotiq_control.launch.py robot_ip:=aaa.bbb.ccc.ddd use_fake_hardware:=<true/false(default)> launch_rviz:=<true/false(default)>

In addition you can start up the moveit interface:

ros2 launch ur_robotiq_moveit_config ur_robotiq_moveit.launch.py use_fake_hardware:=<true/false(default)>

use_fake_hardware:=true

Terminal 1:

ros2 launch ur_robotiq_description ur_robotiq_control.launch.py robot_ip:=aaa.bbb.ccc.ddd use_fake_hardware:=true launch_rviz:=false initial_joint_controller:=joint_trajectory_controller

Terminal 2:

ros2 launch ur_robotiq_moveit_config ur_robotiq_moveit.launch.py use_fake_hardware:=true

servoing

Terminal 3:

ros2 launch ur_robotiq_servo ps5_servo.launch.py

After launching you need to change the controller to enable the servo mode.
Terminal 4:

ros2 control switch_controllers --deactivate joint_trajectory_controller --activate forward_position_controller
