Let's Make Robots!

Ideas needed for a quiet, high quality, small form factor chassis, wheels, and motors.

I'm looking for a source of a small (think deck of cards size) chassis for a robot.  I'm not interested in two wheel or cheap robots, I'd like a decent aluminum or plexi chassis with some higher quality motors and wheels.  Anyone have an idea or recommendation?

How about the Tiny Tank from Rocket Brand Studios? Chris has some other small robots that I don't see listed on his site yet, but if you email him he can probably sell them to you. His Little Line and Ledge robot is a very neat desk robot that can line follow and avoid cliffs. He also has a 'Tadpole' design, which I've seen and is very cool. He's working on more that I know about, but it's not really my place to spill the beans.

Try giving a look at robotshop or robotsavy. They seem to have a good selection of parts and items. You could also try to grab a microwavable plastic container from your local store. There are usually some high quality ones there, though the toughness makes them hard to cut. On the flip side, you get a neat removable lid. No screws required!

Good luck finding anything.

The 3pi is a good high quality, fast, small robot. but it is two wheeled.

You could start by specifying what type of motors you want to use. For example, geared DC motors will need encoders if you want precise control of speed and distance. Stepper motors do not need encoders but can loose accuracy if the robot gets stuck. You should really provide more information on what you want the robot to do.
