Allow me to suggest a test as to whether something is attaching to the carpet. Take a large chunk of wood and attach an eyebolt to the "top" (and, just for good measure, to one side--I'll explain that one in a moment). Set it on a section of playing field carpet, then pick it up with a fish scale or similar device. You will get a force needed to lift it. Now coat the bottom with your choice of traction material. Pick it up with the fish scale again. (Note: You may want to use the side eyebolt to get the new weight of the block first.) If you use more force to pick up the block with the material on it than you do the un-coated block, you're probably attaching to the carpet. There may be some cases where you're not--"other factors" come to mind including statistical variation--but I'd be willing to bet that you'll be ruled as attaching if spotted at competition. Now here's the real reason for that side eyebolt. Put something heavy onto the block and drag it, again using the scale. Change the traction material and repeat. Which one takes more force to pull (and thus has a higher coefficient of friction, and thus more traction)? Maybe that's the one you ought to use...or not, if your strategy doesn't need more traction from that source. |

The vacuum device must use legal motors or pneumatic vacuum generators. Teams have used certain items to gain better friction with the carpet, but these do come at a cost. |
