Take a look at the brochure describing the Gemini robot. Amazingly the robot does all this with microprocessors that ran at one megahertz and with less than sixty-four kilobytes of memory each.

Several articles were written about the Gemini robot, see what Radio-Electronics, Robotics Age and Robot Experimenter all had to say.

The Gemini robot was controlled by several computers and sensor boards. Here are some of the specifications, a picture and schematics on each;

1. •Voice I/O System
