Static warning!!!

Team 135 · #1 10-02-2009, 10:34

As for testing, we have been using a drag wire to discharge the potential difference between the bot and the floor. We know that we cannot do it at the competition, but it is a good thing to do while you are in the shop testing.

What rule prevents you from doing it?

Russ Beavis · #3 10-02-2009, 11:00

As long as it doesn't add traction, damage the floor or connect to either battery terminal, a discharge wire sounds good to me.

Anthony,

As Alan and Russ have advised, yes you can have a discharge wire, In addition to their guidance, I would add to be sure that the wire is always within the "bumper perimeter" and does not pose an entanglement hazard.

Regards,

Mike

As I said this is for testing only for us. The rule says that the only contact with the floor must be with the wheels provided in the kit.

Again I ask: what rule? So far as I can tell, neither the manual nor the GDC's Q&A responses make a static drain wire illegal.

Actually, that's not what the rule says. You'll be safe if you use this simplification but it's not technically accurate.

Does this rework thing solve the problem or should teams still take other precautions?

Russ Beavis · #9 11-02-2009, 11:13

Should solve the problem but other precautions wouldn't hurt. It's always good practice to ground yourself before working with/around electronics.

Thank you. I need to show this one to the rest of the team. It took me a day to convince the team to mount the CRIO on non-static materian (wood). They didn't believe the frame would carry a charge.

<R41> should have convinced them in a matter of seconds.
