(Almost) autonomous kids’ vehicle with Arduino
While the world seems to be focusing on self-driving cars, maker Sieuwe Elferink has instead turned his attention to creating a semi-autonomous kids’ four-wheeler. As of now, the modified device can steer itself within a set of lines, and stop for pedestrians and inanimate objects.
The augmented vehicle uses an Arduino Nano for control, plus a pair of TCRT5000 sensors attached to tubing on the sides to pick up boundary lines. Obstacle avoidance is via an ultrasonic sensor on the front. Four relays are used to activate a former windshield wiper motor for steering through a chain and sprocket system, along with the vehicle’s original motor for propulsion.
The build process is documented here, while code and an electrical schematic is available on GitHub.

That title about gave me chills! Almost autonomous is cute when it’s a 1/2 lb robot dog, worse thing that could happen is you step on it when it’s dark… but a few hundred pounds of Suzuki that ‘Might go around you, might go through you’ could cause more damage than a sore foot lol
Very interesting project though!
