Robot On a Hoverboard - Try 1 By Caitlin, Max, Tycho, Darshan, Omar, Evan, Ethan, and Jayesh

Task: Try to drive the hoverboard with the competition bot

In the middle of Saturday's event we decided it would be a GREAT idea to put the competiton robot on the hoverboard and try to drive it around. Theoretically if we got it centered correctly it could only drive forward and backwards. We could extend the cliff hanger to move our center of gravity forwards, and then retract to bring it back.

Reflections

We were able to make the board speed up by tilting the cliff-hanger out and extending it, but we couldn't control it enough to completely stop it or keep it steady. We believe that the robot frame isn't completely rigid and is torquing at the center, making the robot unbalanced left/right. Since it's only slightly off balance we can't really adjust it by hand. It seems doomed to drive in circles forever. We tried to turn the robot to a correct alignment by driving with the main treads a little, but the change in center of gravity was too dramatic. The robot quickly veered into Evan, who was sitting nearby.
