IMPORTANT: THIS IS ONLY THE OBJ! IT IS NOT RIGGED!
The images are only for reference.
If you want the arm rigged check my profile and select the rigged one.
The robot arm is an unique mesh and unwrapped:
the wirst and fingers are without overlapping, instead the arm is overlapped to save uv space, I show the overlap in one picture.
The preview image is rendered in mental-ray and occlusion.
