Since the optical mouse is a miniature camera, the same type of principal could be applied using the Lego Camera, maybe even with a custom template in VC. This would at least be an "all lego" solution (for the purists out there). The focal point (...) (23 years ago, 1-Jul-02, to lugnet.robotics)

One other interesting thing about this idea-- If it works, not only will you get the optical sensor, but you can probably get up to 5 touch sensors and a rotation sensor at the same time. I'm not sure how the signal is sent, but will the RCX be able (...) (23 years ago, 1-Jul-02, to lugnet.robotics)

Just use the bottom half of the mouse, trimmed as much as possible, as a skid plate. It will need to be mounted to allow vertical movement, but it should work alright. This wouldn't solve the spin issue, but the clearance shouldn't be a problem. A (...) (23 years ago, 1-Jul-02, to lugnet.robotics)

Another idea would be to get a big piece of dry erase (white board). I got a 4x8 ft piece from Home Depot for about $10. Then, your ant could draw all over the 'floor'. You could put a black 'wall' around the edge, to keep your robot inside. This (...) (23 years ago, 1-Jul-02, to lugnet.robotics)
