Loïc has been playing with robotics since the beginning of a side project converting a full size car into and autonomous EV. However, some features can't be tested directly on the full size car. This talk describes the building process of a robotics-ready small scale car made for initial testing, including: - Designing the scaffold to hold the components and printing them - Designing and creating PCBS for the custom hats - Creating firmwares for each components - Creating bridges to control the car remotely with Mavlink and using ROS2 - The challenges met along the way
