Chain contacting BUMP

[RoboTigers1796]

I know you referenced the rule so its not like you haven't read it. Simply showing it for visual purposes.

<R08> ROBOT wheels, tracks, and other parts intended to provide traction on the FIELD 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 also see you say it isn't to gain traction so it is slightly in conflict with the rule. Even with that in mind I don't think it would permitted. Simply because there is too high a chance of it possibly getting caught in the rug as your moving over it and ripping the rug or simply because it will dirty the rug with the grease/oil transmitted from the chain to carpet. Last year we had to cover up a chain system that was a foot above the floor just because it was splashing too much grease/oil supposdly. It also violates the general rule that metal should not be in contact with the carpet. So I would have to say no, the GDC would not permit it, and also your inspector at your regional would not allow it.
Is there that much if an issue you cant bring your chain system higher to avoid contact with the bump while moving over it?
