Rover Control System

Overview

Distributed embedded system with a Raspberry Pi acting as the primary controller (networking, coordination, camera stream) and an ESP32 handling low-level sensors and I/O. MQTT links the layers so commands and telemetry flow in real time.

Technical Highlights

  • Raspberry Pi–based system controller for coordination and networking
  • ESP32 firmware for ultrasonic sensors and low-level I/O
  • MQTT publish/subscribe messaging for commands and telemetry
  • Web-based dashboard for real-time control
  • Asynchronous, event-driven system design
  • Custom rover chassis fabrication
