Science for Kids: Simple Robot Activity

Today we’re building a simple robot using recycled materials. This “toothbot” will be a noisy toy to watch and play with once constructed. So look around the house and grab some old toothbrushes and bottle caps to make this DIY robot!


  • Aluminum foil
  • Soda bottle caps
  • Marker
  • Tape
  • 2 electric toothbrushes

Directions for making a Simple Robot

  1. Tape your two toothbrushes together facing the same way
  2. Cover with foil tightly
  3. Roll up the tape and stick the caps on the underside of the toothbrushes
  4. Draw eyes on two caps and place them on the flush back of the toothbrushes
  5. Turn on the toothbrushes and place the bot on a flat hard surface to watch it spin, move and make clacking sounds.
