RobotCAD 4.0.0 functionality demo
Moreover you can extend RobotCAD controllers by adding your generic controller to ros2_controllers repository by pull request (or locally at your computer). And after that you will be able to construct your specific controllable tool via RobotCAD GUI and automatically generate code of ROS2 package and docker for it.
