Commodore Robotics Page
This is my attempt to interface the Commodore 64/128 with LEGO Mindstorms/Technic built robots.  I used a device called the B100 interface unit from a kit that was called the Robotic Workshop, which was manufactured circa 1986.  I wrote a program which reads a joystick and moves the arm in the direction that the joystick is pointing.  In addition the B100 unit has a built in infrared transmitter/receiver which I programmed to detect when an object is placed between them. Sort of like a motion dectection sensor.  When the beam is interrupted, the program signals that there is an object for the arm to pick up.

This is the arm that I built with my Mindstorms Robotic Invention Kit 2.0.  It is from the LEGO Pro Challenges.  I disconnected it from the RCX and connected it to a B100 interface module for the Commodore computer. As will be seen in another photo.
The B100 interface unit plugged into the user port of my C128.

I used leads with alligator clips to attach the leads of the B100 unit to the Mindstorms motor leads.
