Materials:

  • Disposable cup
  • Electrical tape
  • 3 Markers
  • 2 “AAA” battery holder (Find at your local hardware or electronics store)
  • 2 “AAA” batteries
  • 1.5-3 V DC Motor (Find at your local hardware or electronics store)
  • Clothespin
  • Popsicle stick
  • Googly eyes (optional, you could always just draw them on)
  • Scissors
  • Permanent marker (to draw face, not shown)
  • Glue (optional, for attaching googly eyes. Note that the picture shows Elmer’s Glue, but we ended up finding the hot glue gun worked better.)

1.First tape the markers into the cup as legs.

2. Next attach the battery pack to the DC motor by wrapping the wire around the leads on the motor. (When my kids are older, i’ll teach them how to solder, but for now, this is sufficient.)

3. Now that the battery pack is attached to the motor, tape the battery pack onto the top of the disposable cup slightly off center. I cut the strips of electrical tape in half.

4. Next tape the DC motor onto the cup.

5. At this point you could turn on the motor by placing the batteries into the holder, to see that with the motor not off balance, nothing exciting happens. Next add on the clothespin to the motor and it should start to wiggle a little bit.

6. To make the wigglebot wiggle more, you need the motor to be more off balance. I accomplished this by taping a popsicle stick to the clothespin. However, then my clothespin would frequently fall off of the motor due to the strong vibrations, so I folded the end of a long narrow piece of electrical tape over the motor and then wrapped the tape around the motor so that the sticky side was facing out.

7. Attach the clothespin and weight to the motor.

8. Make a face on your wigglebot, plug in the batteries, place it on a piece of paper and watch it wiggle and spin!
