We made this robot from various junk items: boxes, lids and bottle caps of different shape and size. All you need is to unfold the boxes, then fold them inside out and glue. Afterwards assemble the robot, paint it and attach bottle caps for eyes, ears, knobs and buttons. We also used drinking straws for the mouth. You can play with the robot or use it as a wall decoration, and even give it a hug if it's big enough :)
By the way, you must see the robots Gail from "That artist woman" made with her kids!
