Wandering through the Kay-Bees toys at Barton Creek Mall, I noticed a small robot named BART that was on sale from $17.99 to $1.99. For 2 bucks, it has some nice parts and would make a cool robot chassis. I bought a couple of them and included their autopsy pictures here. I would like to find a schematic for the electronics, but I haven't been able to dig one up yet.
