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)

I'm certain that the optics need to be insanely close to the surface they are monitoring, causing a clearance problem. If such a device was hacked, would placing it in the center of a synchro or Killough platform prove useless in a spin? Rob (...) (...) (23 years ago, 30-Jun-02, to lugnet.robotics)
