New Tread from AndyMark - Pebbletop Tread

[Michael Hill]

Also of particular note is a new pressure transducer. It's very exciting to see an affordable pressure transducer (with a datasheet).

I'm willing to bet this is a product that AnyMark had moulded for them.

I doubt that. I get offers from our suppliers to buy the same stuff.

I'm sure a lot of FTC teams wish this had come out a few months earlier - it looks like a great tread for climbing the churros on the mountain.

That is debatable. The Various FRC treads generally* don't work well on the mountains.

* From personal experience and observations at various competitions.

My point is that the tread pattern here is different from the other FRC treads, in that it has transverse grooves across the whole width rather than angled or interrupted grooves, holes, or a solid tread. If the widths of these grooves and ridges are appropriate, it would mechanically engage the churros better than a solid or angled tread pattern.

We're using 4x 4" colsons for FTC and have no problem driving up to mid. More than high enough for our climbing mechanism to engage the pull up bar for our 80pt hang. It has nothing to do with your tread pattern or which wheel. Teams around us have tried every combination of wheel and it really has nothing to do with engaging your wheel on the churros.

If the geometry of your drive base is done correctly and your COG is far enough forward (something we struggle with every time we add or remove a mechanism), I'm confident a much less grippy wheel like roughtop on the plastic pyramid would work just as well.


That being said, this is a cool alternative for FRC teams who use treaded wheels. The pattern is much closer to the VexPro W-Cut wheels which is probably the best COTS wheel for traction in the forward/backward direction due to the nature of the horizontal cuts.
