SindoorBot: A Tactical Multi-Sensor UGV for Combat Zone Surveillance and Hazard Mitigation

This work presents the design and deployment of SindoorBot, an unmanned ground vehicle (UGV) tailored for combat support, real-time hazard detection, and tactical surveillance. The platform integrates an ESP32-based microcontroller network utilizing the ESP-NOW protocol to facilitate low-latency wireless communication, independent of internet infrastructure. The system features a four-wheel-drive chassis, equipped with fire and gas detection sensors, temperature monitoring, live video feed via ESP32-CAM, and a laser diode for simulated engagement. A custom-developed Android application, interfaced through Firebase Realtime Database, enables remote monitoring and control, providing situational awareness and reactive capabilities in real-time. The modular and field-adaptable architecture of SindoorBot renders it suitable for operations in harsh, communication-constrained, and high-risk environments.
