šļø DIY ROS 2 FPV RC Car: The Ultimate Learning Platform
This is an open-source FPV (First-Person View) RC car project designed specifically for ROS 2 beginners and embedded system enthusiasts. It combines 3D printing, wireless motor control, and real-time video streaming into one compact educational platform.
š¦ 3D Model Overview
The design focuses on modularity and ease of assembly:
- Chassis Base: Spacious interior designed to house all hardware components securely.
- Camera Mount: Elevated FPV mount for an optimal driving perspective.
- Wheels & Tires: Optimized for standard 3D printing materials (TPU recommended for tires).
š Hardware Stack
Powered by the cost-effective and versatile ESP32 ecosystem:
- Main Controller: ESP32 (Logic & Motion control).Ā
- Camera Module: ESP32-Cam (Streaming live FPV video via WiFi).
- Motor Driver: DRV8833 dual-channel H-bridge.
- Actuators: 2x TT Motors (Rear-wheel drive & differential steering).
- Power Management: 2S LiPo battery regulated to 5V via an MP1584 buck converter to power the ESP32 units.
š» Software & Control Logic (ROS 2)
The project utilizes the power of ROS 2 to bridge the gap between a gamepad and the car's hardware:
- Joy Node: Subscribes to gamepad inputs.
- Motor Control Node: Processes joystick data, calculates PWM values, and sends commands to the ESP32 via HTTP/Websockets.
- Camera Node: Subscribes to the ESP32-Camās MJPEG stream and outputs to rqt_image_view.
š ļø Why Build This?
- Educational Excellence: Perfect for learning ROS 2 node communication and hardware integration (like the my_hand_tracker package).
- Wireless Freedom: No bulky cablesāeverything is handled over your local network.
- Fully Customizable: The chassis is a blank canvas for adding ultrasonic sensors or IMUs.
If you are passionate about RC models or ROS 2 robotics, feel free to download, print, and start your journey! Iād love to see your builds and hear your feedback in the comments.
