How many chair legs are in your house? Store the location and size of every obstruction (...) (21 years ago, 5-Nov-03, to lugnet.robotics)

I don't want to spend my life trying to develop fancy ways of representing inch square "occupiedness" by any (...) (21 years ago, 5-Nov-03, to lugnet.robotics)

I know as a programmer, I always try to seek software solutions that maximize the hardware available. Other (...) (21 years ago, 5-Nov-03, to lugnet.robotics)
