The Fast and the Furry-ousThe 7.5-foot slippers are each powered with a 36-volt system that uses six YellowTop 12-volt optimus. The two front wheels are driven by a 7-inch brushed DC motor from Advanced DC motors. There is a welded steel and plywood frame, covered with pink rugs. There is a caster wheel at the back for steering (apparently only fork-lift trucks use this system) and the driver sits on a tractor seat. Top speed is 15 mph.
