The two robots; Hear no evil and See no evil, where created for a module on Autonomous behavior. The robots use a Lego RCX CPU for processing, and they are not connected to any external hardware.
The first part of the movie shows the EMR seeker robot, which marks all of the areas with high EMR noises. The second robot tries to avoid the areas marked by the first.
The second movie shows what happens if ‘hear no evil’ is set loose by itself.
