I would avoid using nail polish, unless it was made by lego :)

I would use lego colored rubber bands on the wires, and colored lego stickers on the EV3. In the past, there were rules specifically against lego stickers, but I don't see it this year. Remember, the stickers (and all lego equipment for that matter, except string) must be in original factor condition, so you can't cut the sticker.

While it does say you "may mark parts for identification on hidden areas", I always took that to mean "identification" as in team name, phone number, robot number (for teams with multiple robots), etc. Not really for identification for what wire goes where, but that could be a valid argument made with a ref. Hard to say.

Other options for marking could be small dots of colored nail polish or the tiny cable ties.

I have no experience whether these would be approved by FLL referees

Hi Leyla

There is a rechargeable battery so you dont have to replace batteries. Get one of those.

Where are you located? I might be able to loan you the extrawe have.


The other way would be the length of cable exactly reaching the right port..

Thanks

Hi all,

I’m sorry if this question has been answered before. Can we use markers to mark the cables? Or use small stickers on them? We are having difficulty putting the cables back every time we change the battery. 

Thanks,
Leyla
