Experience the art of engineering through the mesmerizing kinetic motion of the new VEX® Robotics Pick & Drop Ball Machine by HEXBUG®! Spin the crank to transfer energy through the arm linkages, activating 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. Once constructed, this machine will move the balls in a continuous loop at a rate of 1 ball per second (8 balls included). HEXBUG® is dedicated to inspiring future generations of robotics engineers through the excitement of hands-on learning with fun STEM-based construction kits, like the VEX® Robotics Pick & Drop Ball Machine. This machine teaches important scientific principals such as kinematics, linkages and reciprocal motion. Collect and connect all of the VEX® Robotics Ball Machines.
