Pushing and lifting

Since the triangular arm that ur outriggers fold out from ("wing sheaths") are a few inches of the ramp (~12in i figure from picture) it would be very easy for bots to combine a push with a upward lifting force on these arms . In this situation very little force will actually opposes the bot pushing you (your wheel base is off ramp). The reactionary force supplied by ur outriggers reacting against the mid-barrier will become a torque (instead of opposing pushing) which will be added to the torque of the bot pushing and lifting ur bot. This could cause ur bot to tip over in an incredibly spectacular fall.

With the number of pushers with wedges and forklift stackers i expect to see in this competition, many bots should have the potential to do this. I wouldn't rely on the refs to DQ a bot for flipping u, since u are pretty much fair game on top of the ramp and ur outriggers technically flipped u as much the other bot. U might want to figure out a design mod (suction cups maybe) to combat this strategy.

As for the notion that another bot will be disabled for pushing against u and ur arms damaging the playing field, that probaly will not happen. If the refs are anything like last year, T3 bot will be DQed for any playing field damage. MOEhawk was DQed for bunching the carpet when other robots pushed on our well anchored bot. No damage would have occurred if the the other bot hadnt pushed on a system that takes over 500lbs of force to overcome static friction. They actually caused more damage to the carpet by spinning wheels while pushing. We had 4 or more DQs last year while our opponents had 0 DQs.
