Robots in TDW is handled via the PhysX physics engine. If you haven't done so already, we strongly recommend you read the physics tutorial.
TDW includes a full robotics API. You can add robots to a scene and either set target angles or positions for their joints, or apply forces and torques.
This tutorial will cover how to add and control robots in TDW using a higher-level API (the Robot add-on) and lower-level API commands.
Robots are agents but are not avatars in TDW. Avatar commands won't work with robots.
