Autonomous toy car and FPV car by Inventoteca

Last crawled date: 3 years, 2 months ago

The structure is made of bamboo sticks (⌀3 mm) and 3D printed parts (PLA).
Autonomous toy car
It's controlled by Node MCU 1.0 (aka ESP-12E Dev Kit). It uses an ultrasonic distance sensor (US-100) attached to a servo (SG-90) so it can detect obstacles on the sides. A second servo moves the front wheels and a steering wheel to give it a realistic look. The microcontroller is connected to ESP-12E Motor Shield, the shield drives two gear motors.
FPV toy car
The ultrasonic sensor is replaced by a mini camera, and a RC receiver is added. Speed, steering and camera position is controlled by a RC transmitter.
