Botstop was a 3kg R/C Sumo competitor built by Team RoboMaster that competed in ROBOlympics 2004. It was a two-wheeled, box-shaped robot with a white hump on the top, and instead of a wedge it possessed a plow.
It is unknown how well BotStop did in competition, and it did not return the following year. However the team would later go on to reform as Team Scotbots, and build the highly successful Middleweight, and Heavyweight Combat Robots Ragin Scotsman , and Who's Your Daddy Now?.
