Legal Anchoring?

That is illegal due to rule R06

"ROBOTs must use ROVER WHEELS (as supplied in the 2009 Kit Of Parts and/or their equivalent as provided by the supplying vendor) to provide traction between the ROBOT and the ARENA."

So the actuator would be providing traction, therefore, illegal

Remember, there's a decently sized strip of carpet around the outside edges that should provide much more traction than the Regolith.

I would do this shooting down a rubber pad on a pneumatic linear actuator that would "grip" the floor. The examples in <R06> are for traction devices that propel you, not that stop you, although the wording kind of covers anchoring devices.

The rules seem to be written so that nothing except the wheels is allowed to ever touch the floor. You can interact with the arena walls though <G29>, so perhaps you could figure out a way to anchor yourself that way.

I wonder how much more traction you actually get? Running one of the kit wheels on carpet seemed just as slippery to me as everything else... maybe someone could measure the coefficient of friction just for fun.

I'll probably get in trouble for posting this here, but...is there any rule that prevents you robot from grabbing onto an opponents trailer.

yes <G29>

<G29>
Arena Interaction –ROBOTS may push or react against any elements of the ARENA, provided there is no damage or disruption of the ARENA elements. With the exception of a ROBOT towing a TRAILER, ROBOTS may not grab, grasp, grapple, or attach to any ARENA structure. If a ROBOT violates this rule, the TEAM will be given one warning. If the referee determines that the TEAM is disregarding the warning, their ROBOT will be disabled for the remainder of the MATCH. ROBOTS that become entangled in the ARENA elements will not be freed until after the MATCH has finished, unless the entanglement represents a safety hazard.

I'll grab our wheels tomorrow and see what I can find; we've got some carpet pretty close to the stuff FIRST usually uses.

Unless someone wants to beat me to it.

Regardless, it's gonna be better than on Regolith.

i don't see the wheels providing good traction on anything except maybe lava, tar, sandpaper or any other non-slick surface. lol

You're right. We have some carpet from past WI regionals at our shop. We have not driven a robot on it with the wheels, but from testing by hand, it does not grip well at all.

Tested the regolith vs carpet today. While there is a difference, the grip is still minimal. Hard plastic is not going to get great grip on nearly any surface.
