VEX Robotics Screw Lift Ball Machine Construction Set

“Discover the excitement of engineering with the VEX Robotics Screw Lift Ball Machine by HEXBUG. This modern machine puts a fresh twist on the Archimedes Screw from the 3rd Century B.C. This system is time tested and still used by many industries to move small objects or liquids. Once built, watch as the gears turn, the axles twist and the balls roll as you turn the knob by hand or attach a motor kit to add power to this machine! HEXBUG  believes in using the fun of robotic toys to teach kids important STEM principles through hands-on learning. The VEX Robotics Screw Lift features two alternate builds for more robotic fun! All Screw Lift’s construction pieces are compatible with educational VEX IQ pieces to create your own custom VEX robot and explore unlimited possibilities.”
