Mecanum robot-arm car teaching kit

A teaching kit built around an Arduino UNO mecanum-wheel car with a 3D-printed body, a robotic arm and a separate handheld wireless controller. It is designed for robotics classes, maker labs and hands-on engineering practice. The kit ships with a five-lesson course and courseware.
