So I am starting a WALL-E project with my kids. I like robots, they like WALL-E, its a fit :-) I am using square steel tubing, wheel chair motors, 2 Deep Cycle batteries, and so on. I need to find motor control boards still. I'm guessing when all is said and done he will weigh around 400lbs, a lot of the weight coming from the batteries.
