In this projet we implemented a position control of a litle car we also mecanicaly designed from scratch 3D printing it.
The car has 2 CC motors driven by an H bridge Controled by an Arduino ONE, the arduino get position values from an ultrasound sensor and the arduino code implements a PID controller to define an output value U for controlling the cars position. The hole system is powered by a 11V LIPO battery
You can see the car working by downloading the 'movie' video in Franco folder
The arduino code and the mecanical design files are in the Franco folder
