one thing i noticed and will bring up to my mentors is that when we would do "safe move" auto and get out of the way, the other team would ram the goal into our side and the front omni wheel axles would bend and the chain would fall off. have a "safe" auto.. go infront of the ramp instead of the side so when a team goes staright at the goal and hits it it wont hit your robot and mess it up as much. 
edit: even though we still had 3 wheel drive we still made it to the top and hung every matcht hat the chain fell off, also we had screwed it and pinned it 3 times to the frame, what a mess i have in the pits in atlanta.
