Limits on objects in Alliance Station area?

[Whippet]

T21 The only equipment, provided it does not jam or interfere with the remote sensing capabilities of another Team, including vision systems, acoustic range finders, sonars, infrared proximity detectors, etc. (e.g. including imagery that, to a reasonably astute observer, mimics the Vision Guides), that may be brought in to the ALLIANCE STATION are as follows:

A. the OPERATOR CONSOLE,
B. non-powered signaling devices,
C. reasonable decorative items,
D. special clothing and/or equipment required due to a disability
E. devices used solely for the purpose of planning or tracking strategy provided they meet all of the following conditions:

1. do not connect or attach to the OPERATOR CONSOLE
2. do not connect or attach to the FIELD or ARENA
3. do not connect or attach to another ALLIANCE member
4. do not communicate with anything or anyone outside of the ARENA.
5. do not include any form of enabled wireless electronic communication (e.g. radios, walkie-talkies, cell phones, Bluetooth communications, Wi-Fi, etc.)
6. do not in any way affect the outcome of a MATCH, other than by allowing PLAYERS to plan or track strategy for the purposes of communication of that strategy to other ALLIANCE members..

These are the only restrictions, but pay attention to the definition of OPERATOR CONSOLE:

OPERATOR CONSOLE – the set of COMPONENTS and MECHANISMS used by the DRIVERS and/or HUMAN PLAYER to relay commands to the ROBOT.

(Emphasis mine)

This means that the argument can made that if whatever is being worn by the drivers is not used to assist in controlling the ROBOT, it can be ruled illegal.
