Waveshare RaspRover

Waveshare RaspRover

The Waveshare RaspRover is an open-source 4WD AI robot designed for robotics education and AI application development. It uses the same dual-controller architecture as its larger sibling, the UGV Rover, pairing an ESP32 sub-controller with a Raspberry Pi 4B or 5 host computer in a more compact form factor.

Dual-Controller Architecture

The ESP32 handles real-time motion control with PID closed-loop speed regulation for four N20 encoder motors, while processing data from the ICM-20948 9-axis IMU and INA219 battery monitor. The Raspberry Pi runs Debian Bookworm with ROS2 Humble LTS, handling computer vision, web serving, and AI workloads.

Vision & Audio System

The 5MP camera (160-degree FOV) connects via CSI on Pi 4B or USB on Pi 5. An optional 2-DOF pan-tilt module with ST3215 bus servos (20 kg.cm torque) provides camera articulation with IMU-based stabilization. The onboard audio system includes an SSS1629A5 USB audio controller, APA2068 amplifier, dual-track speaker output, and integrated microphone, enabling voice interaction applications.

Computer Vision

OpenCV and MediaPipe power the vision pipeline: color recognition and targeting, face detection with automatic photo/video capture, multi-object recognition, gesture recognition, and vision-based line tracking for autonomous driving. All features are accessible through a Flask-based web application with WebRTC video streaming.

Communication

WiFi and Bluetooth from the ESP32, plus ESP-NOW for robot-to-robot coordination with approximately 100-microsecond latency. The web control interface requires no software installation. A wireless gamepad is included for manual control.

Power & Expansion

A 3S UPS module runs on three 18650 batteries (sold separately) with simultaneous charge/discharge capability. The 40-pin GPIO header connects to the Raspberry Pi (UART preserved), with additional I2C expansion interfaces, bus servo ports, and mounting compatibility for D500/STL27L LIDAR modules and 4G/5G cellular expansion.
