Looks great!
Full rack capabilities and being able to lift up two robots at once is always nice
One question/caution I have for you is (I am assuming that you plan on lowering all 4 pneumatics at once to lift both yourself and the two robots you are carrying off the ground) how are you going to make sure that all four pistons extend at the same rate and same time? In 2004 we had 3 pnuematics lift our robot about a foot off the ground, then we had a hook that latched onto the bar and we simply retracted our pneumatic feet to score. The problem was we could never quite get the robot to raise up evenly, even after endlessly fidling with the variable pressure valves on each pneumatic to try and balance them. I am worried that if you dont get it just right the robot will go up crooked and perhaps drop one of the robots over the side or even bend a pnuematic shaft.
I like the idea though and its great you got it finished so soon so you have plenty of time to test
