Good god. How does that thing turn?

6" wide wheels...But with 1/8" effective drop on the center wheels. We had 1/16" drop for the previous competition and had problems until later in the competition when the floor was coated with a thin layer of dirt and debris.
The tread in the middle is actually just a bumper I taped on during testing to keep the lifting arm from banging up our own frame too badly when it rotates back.

Just seeing it in a match with that tread, I knew it had to be someone FIRST related.

I am a Team 79 alumnus and mentor. I designed and built Gruff as part of an Undergraduate Honors Thesis project at USF and now compete in competitions with the USF Robotics Interest Group.
