The Lego model uses an Arduino to move the rods up and down (using a servo) and controls the simulated Cherenkov radiation (courtesy of blue LEDs).

From there, it’s really just a matter of printing the claw, connecting it to a 9g servo, and using an accompanying kit to prepare the skin and connect the muscles to the Arduino.

Cantin took to his workshop. He had to scrap his first design entirely when a metal tube attaching a servo-motor to a LEGO brick proved too flimsy (it died during initial testing).
