Named the “Boten Ana” by Aleksey Ermenko, this robot competed in the 2008 FRC robotics competition Overdrive. The drive system had problems at first and ended up becoming a two-wheel powered drive with caster wheels in the back.
There were two main mechanisms for the Boten Ana. The atomic plunger in the middle of the robot used a winch system to push up a PVC tubing and knock-off balls from the overhead rack.
The second mechanism was an extend-able ball catcher that also used PVC tubing, meant to corral the ball around the track.
