Jumping Bunny


What you get

Hop into engineering with this jumping robot bunny! This set includes our Jumping Robot crate plus an add-on kit with materials to give your robot a bunny makeover. (And if you want to turn your bunny back into a robot, you can do that too — just swap out the body pieces!) You’ll assemble a spring-powered mechanism to make the robot hop along, then experiment with the design to customize its jumps and its looks. Along the way, learn how the physics of potential and kinetic energy puts the spring in the robot’s step. Ready to hop to it?

  • All the electronics and materials you need to build the robot.
  • A bunny add-on kit with paper body pieces and wiggle eyes.
  • A 25-page guide with fully illustrated instructions.
  • Robot body pieces plus a set of blank pieces to decorate.
  • Batteries are included.
  • Quality



    From the desk of the product designer:

    Behind the design

    The inspiration for this crate came from our experiments with different ‘costumes’ for the Jumping Robot using the blank body pieces. We thought the bunny was so cute that it would be fun to turn it into a mini kit and up the goofiness by adding wiggle eyes. They bounce while the bunny hops!
