These 4 robots where created for a project. I didn't have any use for them outside of that so I decied to send them here.

All of these robots come with user friendly IK rigs that makes animation easier. There are no textures, and they are not UV unwrapped. only given simple principled bsdf colors, and emission. Robot # 1 features 5 alternative shape key powered eye poses. while robot #3 features 2.Robot #1 eye size differncal differential is controlled by a driver in its rig. The Driver controller is a Transformation constraint in the rig constraint tab. This shape key is driven by the X min value of the constraint. Robot #1 & #2 have B bone rigs for arms that operate similar to IK arms.
The bots are native to a .Blend file for blender 3d, but are in a state that could be easy to convert to any other model format that you see fit.
