Overview

This driver collaborates closely with other ROS packages:

ur_bringup

Package to launch the driver, simulated robot and test scripts.

ur_calibration

Package containing the calibration extraction program that will extract parameters for correctly parametrizing the URDF with calibration data from the specific robot.

ur_controllers

Controllers specifically made for UR manipulators.

ur_dashboard_msgs

Message packages used for the dashboard communication.

ur_moveit_config

MoveIt! configuration for a plain robot. This is good as a starting point, but for a real application you would rather create your own MoveIt! configuration package containing your actual robot environment.

ur_description (separate repository)

URDF description for UR manipulators
