An Intelligent Robotic System For Borehole Child Rescue Operations

Abstract

Borewell accidents remain a critical safety issue in rural and semi-urban regions, where abandoned or uncovered borewells pose life-threatening risks, particularly to children. The narrow diameter, significant depth, poor visibility, and limited oxygen availability inside borewells make rescue operations extremely challenging and time-sensitive. Conventional rescue approaches, including rope-based retrieval and excavation of parallel pits, are time-consuming, hazardous, and lack real-time monitoring, thereby reducing the chances of safe recovery. To address these limitations, an intelligent robotic solution is proposed to enhance the efficiency, safety, and success rate of borewell rescue missions.This paper presents the design and implementation of an intelligent borewell rescue robot capable of performing safe and controlled child rescue operations. The system incorporates an ESP32-CAM module for real-time video surveillance within the borewell. Track-based DC motors, controlled through motor drivers, facilitate smooth vertical movement, while a servo-actuated gripper mechanism is designed to securely hold the trapped child. High-intensity LED illumination is integrated to improve visibility in low-light conditions, enabling accurate positioning and monitoring. The ESP32-CAM transmits live video footage to the operator, allowing continuous observation of the child’s condition and robot maneuvering.During operation, the robot is lowered into the borewell using a cable or rope while the operator observes the live video stream. After locating the child, the servo-controlled gripper carefully secures the child, and the robot is gradually lifted to safely bring the child to the surface.The proposed intelligent rescue system significantly improves operational speed, precision, and safety compared to traditional methods. By combining real-time monitoring, remote control capability, and a secure gripping mechanism, the system enhances the probability of successful rescue. Furthermore, the proposed design can be extended for additional applications such as confined-space inspection, underground exploration, and disaster-response operations.
