Rover wheels on carpet?

[gorrilla]

ok,

there is a similar thread dealing with static elec. and the rover wheels but that was on the regolith...

So each year my school (mount dora bible) holds an expo at the end of January for potential new students, and each year we bring a robot to show off.

Now, the stage in our gym where we hold the expo has carpet on it, not usually a problem, but with these fancy rover wheels there is the chance for the production of high amounts of static-electricity. Compounded with Florida's climate, this is even worse, and could lead to possible human or robot injury.

Discussing this with one of our mentors (also my science teacher) I suggested this problem and that led to "I dont know what we could do but we need to do something" and "we wont have time to change the wheels". And we honestly wont have time to change the wheels, so I've been thinking about other solutions to this problem.

#1. Drag a wire? The stage is all wood, so would having a ground wire dragging still work?

#2. Simply cover the wheels with duct-tape? would that eliminate the static?(easy and cheap)

#3. Do nothing?

#4. Find time to change the wheels? (also includes removing and mounting sprockets and tensioning chain)(then prevents us from playing Lunacy in the future)

thats all I've come up with so far...

what are you guys' thoughts on this?
