Robot Grounded Link

The robot grounded link component allows you to specify the grounded link for a robot, controlled using the integrated robot controller component. The robot controller detects the grounded link entity as an entity that has a physics component, with a joint with the base property set to null. For more details about the robot grounded link component, please see the API documentation.

If you want the robot to be attached to a dynamic rigid body (such as a vehicle), then you will need to set the base property for the first link to any entity of that vehicle. The robot controller will then be unable to determine the grounded link (since no joint has a base set to null). This component is therefore required to allow the robot controller to know what the grounded link is.
