Purnia Students Develop ₹2500 Radar System for Defense
Two ninth-grade students from Purnia, Bihar, Akash Kumar and Piyush Kumar, developed an advanced radar system costing only ₹2500 for military use. Using ultrasonic sensors, Arduino, servo motors, and C++ coding, the system detects suspicious objects and responds by orienting towards the target. Inspired by recent geopolitical tensions, they seek government support to scale the project for border security.
