Hopefully there will be an officially sanctioned solution soon.

actually this is a mechanical solution.
The rule that allows the chain is R05

<R05> Exterior or exposed surfaces on the ROBOT shall not present undue hazards to the team members, event staff or GAME PIECES.

We are not affecting traction as required by R06

<R06> ROBOTs must use ROVER WHEELS (as supplied in the 2009 Kit Of Parts and/or their equivalent as provided by the supplying vendor) to provide traction between the ROBOT and the ARENA....
No other forms of traction devices (wheels, tracks, legs, or other devices intended to provide traction) are permitted.

The chain is a mechanical device fastened to the robot frame and does not violate R41

<R41> All wiring and electrical devices, including all control system components, shall be electrically isolated from the ROBOT frame. The ROBOT frame must not be used to carry electrical current.

By adding a brass chain to the robot frame we have eliminated the buildup of electrical charges. This is a safe and legal method for protecting humans from electrical shock. It also protects the electrical components on the robot.
