How to Build a Small Fake Robot


The great thing about small fake robots is that they can easily be made out of discarded household junk. Recycled cans, broken pieces of toys and even old discarded appliances can furnish the building blocks for your very own junk robot. And because you are making robots out of junk, each will have its own character.

Things You'll Need

  • Scrap metal
  • Discarded appliances
  • Containers and lids
  • Kitchenware
  • Wire
  • Broken toys
  • Various other bits of junk
  • Nuts, bolts, screws and other fastenings
  • Paint
  • Soldering iron
  • Solder
  • Tin snips
  • Tape
  • Epoxy
  • Glue
  • Find or make a body for your robot. The easiest way to do this is to find an old container that looks like a robot body. Pop cans, old hairspray bottles, metal cases from small appliances and other bits of household junk will work.

  • Find a robot head. Again, feel free to use anything that works. Small tins such as the ones Altoids come in make good robot heads. Small metal lampshades and compact jars work well.

  • Find arms and legs. You can use silverware for arms and sometimes for legs as well. You can also use limbs from old broken action figures or bendy metal necks from desk lamps.

  • Find feet. You need one or two broad, flat surfaces to balance the robot on. Jar lids work well and are easy to find.

  • Attach eyes, a nose and a mouth to the head. You can also add antennas, ears or any other features you want. A good way to make the face is to desolder electronic components from a circuit board. You can use resistors, capacitors and other basic components for the eyes and nose and integrated circuits for the mouth. You can then attach them to the head with solder or epoxy. You can also use nuts and bolts for eyes.

  • Attach the rest of the body together. An easy way to do this is to epoxy everything together. For a tighter fit, you can cut holes in the body and fit the arms and legs in. For example, if you are using a metal can for the body, you can cut small holes with tin snips and then slide the ends of the limbs in before sealing them with epoxy. You can also use duct tape.

  • Decorate your robot. You can paint it or, if you prefer, just glue more junk on to it.

Tips & Warnings

  • You will probably encounter quite a few sharp edges in this project. Take care not to cut yourself.
  • Before cutting into an aerosol container such as a pressurized shaving cream can, press the nozzle to make sure all the pressure is out.
