Recycled Materials Robot Craft

I'm always looking for good craft ideas for a hot summer afternoon.  Yesterday, Jack wanted to make a robot.  Hmm... of course, I turned to Pinterest.  We scrolled through hundreds of ideas before I compiled a few.  All we needed was cardboard from a box in the recycling pile, foil, a hot glue gun, a Sharpie, googly eyes, and different-colored craft foam.  I also offered him pop can tabs and milk jug lids, but he didn't use them.
First step: cut out cardboard in the shape of a body, head, arms, and legs. Cover them with foil and tape the back.  Hot glue the pieces into place. 

Second step: decorate however you want!
