Other than that, it is a very innovative and creative last minute decision.
I applaud the team for their efforts that seemed to have worked out for them.

After the pic was taken, the safety inspector said about the same thing regarding the 80/20 posts. The competing version of the robot had 4 very tightly secured L-brackets above the plate to keep it from bouncing around. My only other picture of it is from a distance where a ref and the signs are obscuring the mounts though.
The vices were removed during inspection, as they were deemed a safety hazard.
Engineering tidbit about those zipties: The unnamed main proponent of the zip ties was saying "they're 100lb test, therefore they can hold this 35lb weight". However, you have to consider that while ramming robots/walls/the ramp, the robot will probably decelerate at 5-10g's, thus applying up to 350lbs of force to the zipties as the weight decelerates. When thinking about test strengths, you must also consider the accelerations that those things will undergo.
