Stealth and Apache two small autonomous mobile robots that will play games of "tag" in an arena at Carleton University. These two Robots are the hard work of three engineering students: Yasser, Halim and Bassam. Total cost of the project over $5000 CND and total time to complete the project was 8 long months :) Both Robots use the HandyBoard as the main brain, and Stepper motors to move the cool scooter wheels (no gears). A Wireless camera gives you the Robot's view from the maze and an Optical mouse is used for motion feedback! (replaces bump switches) other features of the robots: MR11 lighs, 4 Sharp GP2D12, IR emitter & receivers, RF communications, 7 pic 16f84 per robot, relays, photocells, low voltage detector and much more...
