This service provides API access to the ROS2 Web API. It utilizes ROS2 to trigger topics, actions and services exposed by the dobot and ROS2 implementation. As such it uses the implementation of Jan Kaniuka (https://github.com/jkaniuka) provided here https://github.com/jkaniuka/magician_ros2. An extension/fork is implemented by OMiLAB and accessible here https://code.omilab.org/omilab-package/dobot-magician-ros2.
These topics are accessible using an MQTT Explorer (like https://mqtt-explorer.com/)
