Sorry Chris, but the geometry of our claw isn't what centers the ball. The bottom tusks spin, actively centering the ball. We have an acceptance range that is over 20" wide, wider than is possible with geometry alone. I have yet to see any other robot which spins the lower part of the claw (but I'll happily be corrected if someone else knows of one.)
