grip on dusty plywood

[Denman]

our mentor brought us in some little square blocks of rubber, maybe an inch or 2 by 3 or 4. I think unfortuneately they are like 5 or so years old so i dont know if they still make them. One of them could pretty much take its own weight when vertical on a hard back book. I'll ask about it for you on thursday.

Check out Skyway wheels. The bead-lok line looks promising.

They make a wide range of wheels though. The ones that sprung to mind are intended for powered applications like robotics. Their tread is designed to produce traction on a wide range of materials, supporting weights in the neighborhood your talking of. They have a good range of sizes and hub options.

Besides that, they are (relatively) cheap! The folks there have been very good to FIRST teams in the past and seem to genuinely like dealing with small guys like us. Mention its for a robotics project and they will probably get into it. You may even be able to talk to their engineers about their products, and get their view.

The Bead-Lok wheels generally come with a foam type tire that is not very durable at all. You might want to look and see what you can find at www.robotmarketplace.com
