Since you can import SketchUp models into ThreeJS using glTF export (Khronos) seems like you ought to be able to make a 3D  visualizer for the robot.

I prototyped this before but this enhancement brings in individual parts to be moved independently so you could do a walking cycle. Unfortunately at the moment I still have not learned things like inverse kinematics (if they apply) and how to automatically move the legs for gaits, so these movements are manually programmed.

Some notes:

• PerspectiveCamera, fourth param is camera frustum near plane (rendering) set that very close 0.01
• light controls the colors
• each gltf has meta info including its model (scene) where you can translate or rotate it
