Matt,
The rules that come into play here are 1) will there be any chance that this would allow metal to come into contact with the floor? 2) will it cause any damage to the carpet.
I think you will find that driving will cause this setup to heat considerably from the friction with the carpet. If the answer to either of the questions above is yes, it will not be allowed. The first is an inspection issue reguiring a close up look at construction and implementation. The second is to be determined by field people. If they think any damage is possible, they may disable your robot and disqualification for repeated offenses is a real consideration for your team. Without close inspection, only you can make a determination at this point.
