Microrobot Motor Mover?

Does anyone know exactly what this <http://home.cfl.rr.com/rigdon14/microrobot/box.jpg> is? I found it in a pile of surplus material yesterday. It appears to be a computerized controller for a robotic arm. The box is marked Microrobot Motor Mover. Inside it has a large circuit board with a 6502 CPU, two 68B05 MCU ICs, a 6522 VIA IC and an EPROM and two external DB-25F connectors. It looks like a complete microcomputer controller that can be controlled by a computer or via the front panel. There's also a daughter board that sits on top of the main circuit board. It also has two Opto 22 OAC% solid state relays that appear to control the AC sockets on the back of them box. Around the large hole in the main board, there are a number of connectors that have cables that run to the back of the box. The connectors are marked Wrist (2 each), Grip, Elbow, Base and Shoulder.
