Wheels for robot

[dirkwillem]

Hello

I'm building a robot with my Raspberry Pi and Arduino, and I've got almost all the parts. The only thing I'm missing are wheels.
I've searched every place I could think of, but I haven't found anything.

I've got two types of motors, one is a slow geared motor, so it will have to drive a wheel directly.
The other type is a fast, not-geared motor, so it'll need some gears.

The geared motor has an axle diameter of 5 mm.
The non-geared motor has an axle diameter of 2mm.

Does anyone know where I can get wheels (and eventually gears and axles) for this?

Many robot shops have wheels, including robotshop.com, pololu.com, sparkfun.com, and servocity.com.
You can also use RC car/truck wheels for some kinds of mountings/motors.

In general, there are three options:
1) Wheels with the exact diameter you have, and some kind of fastening option.
2) Wheels with a known mounting pattern, and a shaft adapter that goes from you shaft to the wheel. RC style "hex hubs" are an example of this.
3) Wheels with no center; you drill your own hole.

Thanks, I didn't know those sites were there. That was just what I needed!
