Team 40's robot seems pretty simple to me. It is simply an aluminum ball on the end of an arm that telescopes and rotates on a shoulder. Its very simple, yet very effective, just drive up to the auto loader and get the ball somewhere inside the tetra, the lift the arm and you have one tetra perfectly placed and ready for delivery. Oddly enough, we got the Driving Tommorow's Technology Award for putting a ball on the end of an arm
From what I've seen, it seems that the simpler the design, it more effective a robot is, at least this year.
