The structure is crafted from durable bamboo sticks measuring 3 mm in diameter, combined with precision-crafted 3D printed components made of PLA plastic. **Independent Toy Vehicle** This innovative toy car is expertly controlled by the Node MCU 1.0 microcontroller, also known as the ESP-12E Dev Kit. It employs an advanced ultrasonic distance sensor (US-100) securely attached to a highly responsive servo motor (SG-90), enabling it to detect obstacles on both sides with ease. A second servo motor skillfully moves the front wheels and steering wheel, giving the vehicle a remarkably lifelike appearance. The microcontroller is seamlessly connected to the ESP-12E Motor Shield, which expertly drives two high-performance gear motors. **FPV Toy Vehicle** The ultrasonic sensor has been replaced by a cutting-edge mini camera, and a reliable RC receiver has been added for enhanced functionality. Speed, steering, and camera positioning can be precisely controlled using a state-of-the-art RC transmitter. **Comprehensive Parts Overview** The following components are required to bring this innovative project to life: * 11 Nylon-insert lock nuts measuring M3 in diameter * 16 flat washers with an external diameter of 7 mm, internal diameter of 3.2 mm, and a thickness of 0.5 mm * 13 bolts measuring M3 in diameter (various lengths) * 4 screws measuring M2x10 (or similar) * 4 screws designed to mount servos * 18 bamboo sticks with a diameter of 3 mm (various lengths) * 2 high-performance gear motors * 2 micro servos (SG90) * 25 precision-crafted 3D printed components for the autonomous version * 26 precision-crafted 3D printed components for the FPV version * 1 advanced ultrasonic distance sensor (US-100, 3.3 V) for the autonomous version * 1 high-quality mini camera (Eachine TX02 NTSC) for the FPV version * Cyanoacrylate adhesive * Cables for seamless connectivity **Stick Lengths** The following lengths of bamboo sticks are required: * 2x 15 mm * 2x 70 mm * 1x 80 mm * 7x 90 mm * 2x 100 mm * 2x 130 mm * 2x 180 mm **Bolts and Screws** The following bolts and screws are required: * 4x bolt M3 x 15 * 4x bolt M3 x 30 * 3x bolt M3 x 20 * 2x bolt M3 x 5 * 4x screw to mount servos (included with SG90 servos) * 4x screw M2x10 (used to secure horns to servos and wheels to gear motors)
