very very cool!
I must admit that when I first saw your concept for climbing I picked my jaw up from the floor and said: "wow, no way they can make that work!"
Seeing it now, I think I might need to buy a new hat!
It looks amazing both in concept and implementation. I love how the rotating arm can be used both to aim the frisbees, get into/out-of starting configuration, gets you to the feeder slot, AND is integral to the climb. very impressive!
what motors are you going to use for the climb? (assuming the two CIM on the arm are for rotating the arm)
