I was able to get a few pictures of the robots. Some of them had frantic owners scrambling to make last minute repairs and software adjustments during the segments of the race, so I did not want to disturb them. All the robot owners I did ask were happy to share.

This one uses LIDAR!

This robots owner was dressed like Mario!

The Ant from tangibletec.com

This one weighs 25lbs and goes 60mph (97Km/h)

This has mostly recycled parts.

I didn't believe it the first time, but this one is only prop driven.
