Build an energetic bouncing robot that uses an electric motor and a spring-loaded mechanism to jump forward in a continuous motion.

  • Instruction Manual Included
  • Eight Models to Build
  • Elasticity, Potential and Kinetic Energy, and Other Concepts Covered
  • Mechanical Components Featured: the Spring, Cams, and Motor
  • Models Include a Crab, a Robot, and an Amusement Park Ride
Watch the robot crouch down, compress its coil spring, and store up energy. Then see how it instantly extends its legs and releases the stored energy all at once, launching itself upward and forward. Experiment with the metal coil spring to discover how the robot’s jumping mechanism works. See if the robot can jump over objects in an obstacle course you design for it. Learn about elasticity, potential and kinetic energy, the spring constant, cams, and linkages.

Build seven other functional models using the same mechanical components—the spring, cams, and motor—to perform other tasks and demonstrate physical science principles firsthand. Construct a car that moves forward on spiral-shaped wheels. Make a spring-loaded pitching machine that repeatedly winds up and propels a ball forward using spring power. Build a crab that moves sideways, a kicking machine that uses the spring-loaded mechanism to propel an object away, and a grappler claw that grabs onto things. Assemble a fun amusement park ride that spins around using the electric motor. Learn about the physics of force, mass, and weight by making and experimenting with a spring scale. The full-color, 24-page instruction manual provides step-by-step illustrated assembly instructions.
