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).

Serial Servo HATs and Raspberry Pi, Arduino expansion boards 3:15 pm October 2, 2023 By Julian Horsey While building robotics projects, the importance of controllers and motors cannot be overstated.

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).

It is a robot made of Arduino and Lego NXT components based on the Segway. A software library to control LEGO NXT motors and a few sensors he used is available on SourceForge.

Enhancing Lego Mindstorms with Arduino Lego Mindstorms NXT is a sophisticated and fun educational robotics set that teaches kids and adults engineering and programming skills.
