Our dimensions (before bumpers) are 22.5 x 24.5 x 35.5, and we have discussed the potential for falling over. Luckily, about 80% of the weight here is within 8" of the ground, and that only looks better when we add bumpers and a battery.

We took a lot of inspiration from 111, 1918, and 2775's 2009 robots here.

Thanks for letting us know, with such certainty, how our robot will perform. I can only assume you're building the exact same robot and have already driven it?

Personally, I'm curious about how that ramp is getting raised and lowered. I'm liking the concept though--this is borderline cheesecake-able to help a team operate at a higher level.
Without going into too much detail about our game analysis, we identified 2009 very early on as our primary year of focus in robot design.

That ramp (elevator carriage) is supported on each corner by a 3D printed bracket bolted to a linear bearing. The bearings are each riding on a stainless steel rod, one in each corner. The current plan is to have a run of #25 chain on either short side of the robot (two total) and bolt the chain to the carriage. Idler sprockets at the top of the robot will be connected by a shaft and we'll tuck a gearbox in the drivebase to power it on one side.
