: Here it is. The arm movement at the time of tipping is autonomous. The gyro is used on the arm for the purpose of maintaining its position under load (the arm fights the force trying to change its position).

Actually, to correct Ben, the arm movement that resulted in the tipping of Bay Bombers was not autonomous. The arm will only react when the angle of the robot base is changed in relation to the playing field. The Gyro works perfectly for what we use it for.

Now for the real story, the arm was being moved up and down for the last 30 seconds or so of that match in order to jolt our robot up onto the puck. We were working with our CG. We had to do this because the opposing robot was pinning ours between the puck and the edge of the playing field. Our robot was only able to get up onto the puck after the force from the pinning robot was removed. It was removed because the robot was tipping. If you watch closely, the 192 robot only gets fully onto the puck after the Bay Bombers begin to tip (and then drive their base out from under their own robot).

However, I am not posting this message to dispute the judges call. The judges call is final and our team is well aware of that fact. We are mearly posting this clip to clear the GRT name. Our team is not "unsportsmanlike" as the judges made us out to be. The call is final.


Hope the video cleared things up!
See you in Florida!!
