In 2016, I organized a workshop in a scientific summer school, where we built four auto-aiming catapults with a group of 16 years-old students.

The catapults are based on Arduino Uno, Tamiya Twin-Motor Gear Boxes and HC-SR04 ultrasonic sensor; the frame is made of plywood.

The goal of the workshop was to learn how to operate the wood workshop tools, and learn the mechanisms of motors, microcontrollers and ultrasonic sensors.
