MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641043598 A) filed by Gnana Deepak M; Karthikeyan S G; Giridharan S; and Gurupandi D, Chennai, Tamil Nadu, on April 6, for 'autonomous landmine detection system using esp32 microcontroller, metal detector, gps, gsm and iot-based real-time monitoring (alds-rtms).'

Inventor(s) include Gnanadeepak M; Karthikeyan S G; Giridharan S; and Gurupandi D.

The application for the patent was published on April 17, under issue no. 16/2026.

According to the abstract released by the Intellectual Property India: "Described herein is an Autonomous Landmine Detection System with Real-Time Monitoring (ALDS-RTMS), an embedded hardware and IoT-based autonomous robotic system designed to detect buried metallic landmines and convert detection events into simultaneous GPS-tagged SMS alerts and cloud-based IoT monitoring outputs in real time, enabling safe, remote-supervised demining operations without requiring human operators to enter hazardous areas. The system integrates an ESP32 microcontroller as the central controller, an inductive metal detector module for subsurface metallic object detection, a GPS module for geographic coordinate acquisition, a GSM module for SMS alert transmission to predefined operator numbers, an HC-SR04 ultrasonic sensor for autonomous obstacle avoidance, an L293D motor driver circuit for differential drive robot locomotion, a 16x2 LCD display for local status output, and an IoT cloud platform interface for remote real-time monitoring using the MQTT protocol. Upon confirmed metal detection, the system autonomously halts locomotion, acquires GPS coordinates, transmits an SMS alert with location data, publishes detection events to the IoT cloud dashboard, and updates the local LCD display, all without requiring human intervention at the detection site. The ultrasonic obstacle avoidance subsystem operates continuously and independently, ensuring safe autonomous navigation throughout the detection mission. The system is designed for practical deployment in post-conflict demining operations, humanitarian mine clearance activities, military field applications, and border security monitoring in environments where direct human access is hazardous or impractical."
