Fiery Half Body Robot Pushes Shopping Cart

This Fiery Half Body Robot Pushes Shopping Cart is just what I need to push my groceries home from the store. I would love to film this thing walking into a Walmart past the greeter. 🙂

"An electric motor was used to drive the rear axle of the shopping cart. The same motor turned a bicycle camshaft which pulled slowly, then released quickly 2 cables. The radio control consisted of 2 channels. 1 would be a simple switch (forward/stop). The second was connected to a H-bridge constructed from 2 Double Throw Double Pole switches. The switches were made from wire and glue and a coat-hanger."
