Hello, it's Grayson!
I wanted to talk about Team 610's shooting alignment mechanism from their 2013 robot. We saw this robot in action at Granite State Regional that year and it was one of the most effective and efficient robots there.

This is a video of their robot in action. I was most impressed with the mechanism they used to line up their shooter with the goal using the pyramid as a marker. Their robot could not be touched because it was in contact with the pyramid, and the mechanism was sort of passive and simple. The robot would line itself up by basically just extending hooks and driving up to the bar of the pyramid, and then would PUMP frisbees into the goal almost indefensibly. And at the very end of the game, the robot would line itself up one last time to achieve a 10-point climb. This mechanism was good in two ways: it worked well and was reliable, and the strategic theory behind it was uniquely thought-out.
