Electronics Update:

I designed and printed a new box for the electronics. It was made of two 3d-printed halves, which I plastic-welded together. I then added some Bondo and spray paint to make the box look cohesive. I also added some connectors to easily detach the electronics from the robot arm.

Base Update:

I mounted the robot to a 3/4" piece of MDF. I added some 1/2" bolts on the corners to prop the piece up and make room for the mounting screw heads/ends.
