Taking inspiration from Colin Furze’s 600cc bumper car constructed a few years ago, Henry Forsyth decided to build his own RC miniature version. His device features a 3D-printed and nicely-painted body, along with a laser-cut chassis that holds the electrical components.
The vehicle is driven by a single gearmotor and a pair of 3D-printed wheels, with another caster-style wheel that’s turned left and right by a servo steering. An Arduino Uno and Bluetooth shield are used for overall control with a motor driver.
The Bluetooth functionality allows for user interface via a PS4 controller, or even (after a bit of programming) a Wii Balance Board. In the end, the PS4 remote seems to be the better control option, but who knows where else this type of balance technique could be employed?
