Look for a local Wheel chair sales and repair place.
They probably will have old wheels chairs that you can buy from them cheap.
Or keep an eye on the local classified ads for used wheels chairs. This includes Craigs list, free cycle and some other online personal market places.

You only chance to do this cheaply is to obtain used and scavenge parts.

You can also look into car starter motors at auto wreckers or craigslist. Motorcycle starter motors might be a little harder to find cheap. Wiper motors and window motors might also work for you but they are not as powerful as the starter motors. Nice thing about car parts is you will be able to find them well into the future if your robot brakes.
