I really like the way your robot looked at Sacramento. Simply one of the more creative looking robot outs there.

From a robot design stand point, I want to ask why you guys didn't put the motors on each arm together and have it drive 1 telescope up to the bar instead? I noticed that you need both arm on the bar to have enough power to pull up, and having 2 arms create the risk that both might not be on at the same time.

I think I have a quick solution. Simply program the arms to go up at the same time, and joint the end of the arm together so even if only 1 of the grabber reach the bar, you can still pull up.

It's kind of like drive train with 4 motors, do you join the 2 motors on each side together? Or do you have 1 motor at each wheel. What people found out is, if you have 1 motor at each wheel, when only 1 wheel is touching the ground, you only have the power of 1 motor. If you join the 2 motors together and have a tank drive, each side's wheels have 2 motor's power even if only 1 wheel is touching the ground.
