Making Mobile Robot…?

How might one go about making a mobile robot that could pick up stuff and move it a few feet? The trick is… it’s gotta fit into a 30 cm qualifying cube (you can squish it in there…as long as it fits) and pick up: ping-pong balls, legos, 9-V batteries, a tennis ball. We can get a pre-made thing…but have to alter it somehow. The goal is to get all the objects into a coffee can about 2 feet away from the starting point. It’s also gotta get over (and come back over) like a small crown
molding thing. Its gotta be remote contolled, too. If anyone knows anything about this or knows somewhere I could order or go buy one, let me know! Thanks!

Not sure about a premade, but a platform that was car shaped, using four electric motors to turn large foam wheels or spoked wheels would over come the crown moulding. Hook the right side motors together, and the left side motors together, and you could turn it, much like a tank does by stopping one track while the other turns. A boom that hangs over the side could be used as a crane, and just position the vehicle next to the item and lift it, then drop it into the container. You might could use a Tonka Toy type vehicle, that was already remote controlled, and mount the guts on a peice of plywood to make it fit the cube. Toys-r-Us time, and good luck!!!
