Autonomous toy car and FPV car
Description
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. **Part list overview** 11 Nylon-insert lock nuts M3 16 Flat washers M3 (⌀external 7 mm, ⌀internal 3.2 mm, thickness 0.5 mm) 13 Bolts M3 (various lengths) 4 Screw M2x10 (or similar) 4 Screw to mount servos 18 Bamboo sticks ⌀3 mm (various lengths) 2 Gear motors 2 Micro servos (SG90) 25 3D printed parts [Autonomous version] 26 3D printed parts [FPV version] 1 Ultrasonic distance sensor (US-100, 3.3 V) [Autonomous version] 1 Mini camera (Eachine TX02 NTSC) [FPV version] Cyanoacrylate Cables Parts 18A and 18B are for different sizes of ultrasonic sensors.
