pool noodles

[hrench]

If you get the the store at just the right time, when they're clearing out the pool supplies for fall, you can talk to the manager and offer $1 a noodle for the case(s) and no foolin', that works.

Did get all pink noodles, but that's no big deal. Can't see 'em on the 'bot anyway.

As for 'solid' noodles, can you foam 'great-stuff' into the center? I think maybe you want your bottom noodle to be solid and the upper noodle hollow, so you'll get a wedge-effect that gets the other robots' weight onto your machine so you get the traction. Would that work?
