2012 KOP wheels

[apalrd]

We used Plaction wheels in 2010, and (like many teams that year) started breaking them going over the bumps (although we were a bit rough with the bumps...)

We ended up cutting two pieces of polycarbonate that perfectly fit the space between the spokes, and bolting them together, to strengthen the wheel. Due to weight concerns, we used this to repair wheels that were starting to crack, and did not put these in every spoke cavity of every wheel.

You could do something like this for any 6" or 8" plaction or kit wheels if you are concerned with breaking on a field object, although this is highly game/field specific.

The kit wheels worked great for us for our practice robot, but for our real robot, we used Plactions.

In an effort not to derail this thread, I started a new topic discussing coefficient of friction:

If anyone from this thread did some quantitative testing, I'd love for you to chime in.

One thing I'd love to see from AndyMark: 4" versions of the 2012 kit wheels. I'd definitely order a set if they were available.

we tested with KOP wheels, wedgetop and blue tread (McMaster).

We found that the blue tread got better grip on the ramp and on the carpet.
It also holds up well when dusty / dirty.

JVN - for your question, see your other thread.

Id like an 8 in version

We used them all season. 6WD...loved them. We were always able to get to where we wanted to go. Excellent traction on carpet and especially on the bridges. We never spun when pushing another bot up the bridge.

AndyMark has done an excellent job with these wheels.
