Motors Help

OK so im completely new to using motors with Arduino. I am looking for motors that will work with these tracks http://www.vexrobotics.com/276-2168.html I am thinking of using 2-4 motors. !st of what is the easiest way to control and power these motors. They need to be able to move a robot around that could weigh anywhere from 25-50 lbs.

Thanks for your help and guidance.

I'd be surprised if these plastic treads are going to be capable of supporting a 50-pound robot.

Looks like they are designed to be powered by a continuous-rotation servo.

Do you have any idea of treds and motors that could support that?

Have you thought about homebrew?:

Take a gander around that website a bit, and you'll see what people have done on the homebrew front for tank treads; maybe you can get some ideas?

A google search for 'robot tread heavy' turned up some sources:

That's listed under the heading "Series 820". If you look further down the results for McMaster-Carr you will find six choices for Series 820 drive sprockets and four choices for Series 820 idler wheels.

Wow, i completely missed that! Sorry thanks so much!
