Jumbonator is a 12lb battlebot designed by Jon Gowa, CAD'd by Will Langford, and built by the two of them. It first competed at Motorama 2009 and later the same year at the Franklin Cup. To our knowledge is the only hobby-weight pneumatic flipper in the Northeast Region.
For Motorama 2010 we redesigned the flipper arm and added an IR sensor to the front of the robot to allow it to semi-autonomously flip the other robots. Check out how awesomely it works in the Motorama 2010 vid!
