M17: robot wheels, tracks, and other parts intended to provide traction on the playing field ("traction devices") may be purchased or fabricated. in no case, will traction devices that damage the carpet or other playing surfaces be permitted. traction devices may not have surface features such as metal or hard plastic studs, cleats, or other attachments. the other surface of off-the-shelf wheels may be modified by removing tread material only. in no case may a traction device protrued beyond the bottom surface of the Ramp mesh. gaining traciton by using adhesives or velcro-like fasteners material is not allowed.

ok... so i've got a few questions:
1. if you have a foam thingy on the bottom of your wheels, and the weight of the robot presses it into the mesh so part of it protrudes through, is that in violation of the rules?
2. i saw a robot last year that used a belt with metal upside-down 'U'-shaped things to grab onto the carpet... that isn't allowed this year, right?
3. our mentor used some polyurethane foam stuff with some traction pattern cut out of it attached to their wheels last year. is that not allowed this year? it says that the outer surface of off-the-shelf wheels may be modified by removing tread material only.
