To be more precisely, Dycem is an anti-slip solution that used for on zimmer frames to not slip on it. Same with jars, people who can't opend them who needs better grip.
Read more about it on www.Dycem.com

But I like Lint roller much more

i have heard some robots apply a tape to their wheels for grip

How effective is this?

Lint roller is a bit like a double-sided sticky tape. Dycem isn't exactly sticky but it sure clings to lots of things!
True double-sided sticky tape is really TOO sticky, but does give some fun effects!

What you really need above all is a large surface area in contact with the floor, so wide, soft tyres are the order of the day. The thicker mouse-mat foam is good, especially with elastic band or Dycem "tread" over the top.
Avoid very soft "open cell" foam, since it is just too weak and gets torn apart by the torque of the wheels.
You can make elastic bands sticky by spraying them with WD-40, which attacks the rubber and makes it sticky. Of course the bands need replacing frequently, but at least they're cheap.

Double sided stick tape is only useful until your bot hits debris, dirt, grease, shavings, muck, dust, lint or anything...

Basically things get stuck to the wheels then your grip goes... The lint roller stuff is the same after a fashion, but it can be cleaned...

Hunt out dycem if you can find it.

A question for the commitee members regarding a design I'm currently working on;

If a robot had a peice of metal that was a wedge, but was also bent down at the sides to become the side armour of the robot, would that be allowed in the current/upcoming rules? The single peice for the sides/wedge is the only peice of metal on the robot.

I would have thought it depends on how much of the robot is covered by the metal. If it is just a scoop at the front say covering less than half the robot I would have thought it was OK but if it affords protection to much more than that I would say no. Perhaps you could put up a sketch.

Classified information I'm afraid

but the Wedge is the whole weidth of the front of the robot, and the side armour (folded down from the wedge) runs all the way from the front to the back of the robot. So I assume that would be a no from you?

I take it to mean as long as the whole armour of the robot isn't one continuous plain, then it would be ok. But I've had problems understanding this rule myself, and broken it on one occasion with a superant.

Badger? That wasn't metal, I thought it was butter? Well it cut like butter
