The robot circuit boards are inside the first frame: open the white door and
you should see them mounted on the back wall. The one time this happened to
us, the robot was jammed (installation error: retaining pin left in place)
such that it blew a safety fuse on the board. A flashlight and a Radio Shack
fuse might get you back into operation quickly if you find it to be something
like this (as in the case of a dropped tape blocking movement).
