After seeing all the triple balances this weekend, I remembered a small robot I helped a rookie team (2250) design and build in 2007. It's purpose was to climb any robot ramp that year. Here's a video..........

If you built a similar bot this year it could easily 'sandwich' between two other bots making a triple balance easy. You could easily fabricate a chassis and integral bumpers that would weigh less than 30 lbs. Together with a minimum of COTS components you could easily fabricate and drive a robot like this on the Thursday of a regional. You might also do well with this bot balancing on the coopertition bridge during qualifying matches. Then in elimination rounds with the right other two bots you could easily help make 40 plus scores a probability.
