Subzero Leaps to the Attack

THE D49 CYLINDER WAS USED IN SUBZERO ON BATTLEBOTS

Jerry Clarkin and Jon Durand entered their robot SubZero in a regional Battlebot contest. They used a D49 cylinder with some recommended changes from Motion Controls for their robot, SubZero. Dual onboard CO2 bottles were used for power – looks like it did the trick. They placed third in the competition, 120# class. They said they should have had 1st or 2nd, but there were some bad calls by the referees….

The Motion Control pneumatic cylinders will be doing battle again soon, June 16-18 in San Francisco at ROBOlympics, www.combots.net
