Other than that, very simple designs seem to prevail this year. A simple t-bar seems to work quite well. |
While it is cool that they can pickup 2 tetras at a time there was a minor flaw in the elevator system. During the (I believe) quarter finals in LA, a force was applied to the tetra grabber by pulling down and away from the robot by an opposing team. The top of the elevator mechanisms came off of the robot rendering them useless for the remainder of the match. It was fixed in time for the next round. I think if they had designed it a little simpler by using less string and metal that was a little more structurally sound, this might not have happened.
