"I'm a bit fuzzy on the whole good/bad thing here. "
In Section 8.3.1 under R08 it states:
Quote:

ROBOT wheels, tracks, and other parts intended to provide traction on the carpet may be purchased or fabricated (“traction devices” include all parts of the ROBOT that are designed to transmit any propulsive and/or braking forces between the ROBOT and the FIELD). In no case will traction devices that damage the carpet or other playing surfaces be permitted. Traction devices shall not have surface features such as metal, sandpaper, hard plastic studs, cleats, or other attachments. Anchors (i.e. devices that are deployed/used to keep one’s ROBOT in one place and prevent if from being moved by another ROBOT) shall not use metal in contact with the carpet to “stay put.” Gaining traction by using adhesives or Velcro-like fastener material is not allowed.

I believe the whole intent of R08 is to prevent damage to the field which is good but the Rule seems ambiguous and general and as a result overly restrictive when it comes to materials and design of a track.
Specifically my questions are:
- Can you use a metal track that has "treads" (not "studs" or cleats")?
- What is "hard" plastic? Is "hard" quantified using the Durometer or Rockwell scales?
- What is meant by "other attachments"?
A conservative interpretation could be that you couldn't use metal or "hard" plastic chain but a "hard" rubber chain (or timing belt) is okay.
More importantly if you "fabricate" a track using commercial components then what qualifies as an "attachment"?
