Raspberry Pi4 Rover

Overview

An autonomous rover built around a Raspberry Pi 4, with a fully custom 3D-printed body designed in Fusion 360. The rover runs Node.js as the main process, spawning Python child processes for motor control and camera handling.

Live video and audio stream from the rover to a remote PC using WebRTC, with TURN/COTURN servers self-hosted on a home server for NAT traversal. Command input is handled over WebSocket connections routed through a reverse SSH proxy, also hosted on the home server.

The rover features a solar panel charging system for extended outdoor operation.
