Spin the crank to transfer energy through the arm linkages. The transference of energy activates 3 sophisticated grabber hands that reach down and grab a ball. Keep spinning the crank to hoist the ball to the top of the machine where the grabber arms will automatically release and drop the balls onto the return ramp.
This VEX construction kit is a practical introduction to kinetic energy. No batteries are required! Simply use to hand crank to set the machine in motion.
Connect over 400 VEX pieces to build your own robot. Includes 8 balls.
