Barbot by Aaron Wilson

Barbot was first a photropic design but evolved into a
whisker driven unit. Barbot uses a PIC16C84 brain programed
through a PicBasic Pro compiler. For motion the Barbot uses
two hacked servos with RC airplane tires. The whisker
sensors ride on pingpong balls attached to pieces of
welding wire that pivot on a shaft. When the ping pong
balls drop (edge of the bar) or raise (the bar counter
lip) the ir beam is broken and the PIC turns the Barbot
the other direction. The ir sensors are from an old mouse.
