ROBOTIC ARM by Science Educators

Sometimes, an object you need is just out of reach - like the TV remote on the coffee table or your favorite throw blanket that's ALL THE WAY over there. How could you build a robotic arm that extends so you can grab those hard to reach items? Look at the picture for ideas on how you can build a similar tool. You can try this fun activity at home or in our DIY makerspace, Tinkering Garage!


  • Popsicle Sticks
  • Small Bottle Caps
  • Wooden Skewer
  • Scissors
  • Drill with a Small Bit
  • Box-Cutter 
  • Hot Glue Gun 


Use a drill with a very small bit to put holes in the in the Popsicle sticks. WARNING! Please have an adult help you make the holes. Cut your wooden skewer into tiny pieces and use those pieces to connect your Popsicle sticks using the holes you drilled out. Repeat this step until you feel your new robotic arm is long enough! Use the bottle caps to make nice handles for your fingers to grip, but remember to ask an adult to help you drill these as well!

Further Exploration:

  • Try picking up different things with your robot arm. What kinds of things are easy to grab? What things are hard to grab?
  • How can you make your robotic arm stronger?
  • How far can your robotic arm extend? How can you make it extend longer?
