About

Purushottam Shekhar is a researcher specializing in intelligent transportation systems and infrastructure monitoring, with a particular focus on railway safety and automation. His most cited work, "Automatic detection of squats in railway track" (2015, 12 citations), introduces a novel crack-finding robot that integrates a microcontroller with ZigBee communication, GPS, and an IR-based crack sensor to detect voltage variations indicative of track defects. This contribution addresses a critical need for cost-effective, real-time monitoring of railway infrastructure, offering a practical solution to prevent accidents and reduce manual inspection costs. Shekhar’s research bridges embedded systems, sensor technology, and civil engineering, demonstrating a clear impact on safety-critical applications. While his citation count reflects a niche but growing field, his work has laid foundational groundwork for automated track inspection systems. His achievements highlight a commitment to applying engineering innovations to real-world challenges, making his profile particularly relevant for students and researchers interested in the intersection of robotics, IoT, and transportation safety.
