Budget Extensions - 30lb Combat Robot
In my second year in the UIUC iRobotics club, we set out to design a robot with the goal of having a huge spinning weapon on top. We designed a 30lb "Featherweight" class combat robot with a large 20" overhead blade. As the chassis lead on the team, I led discussions involving overall robot-architechture questions and designed and manufactured much of the robot.
