About

Dr. Harkishan Singh Grewal is a leading researcher in assistive robotics, with a primary focus on developing intelligent mobility solutions for individuals with severe physical disabilities. His work centers on autonomous navigation, computer vision, and human-robot interaction, specifically targeting the creation of self-driving wheelchairs that can operate without pre-existing maps. Dr. Grewal’s major contribution is the design of a LIDAR-based autonomous wheelchair system, which allows users—including those with arthritis or motor neuron diseases like ALS—to navigate safely without requiring fine motor control. His foundational 2017 paper on this system has garnered 51 citations, establishing it as a key reference in the field. He further advanced the technology in his 2018 work on navigating unmapped indoor environments, which has been cited 20 times, addressing the critical challenge of real-time obstacle detection using point cloud data. By integrating LIDAR and computer vision, Dr. Grewal has pushed the boundaries of assistive technology, enabling greater independence for individuals with limited mobility. His research continues to shape the future of autonomous wheelchairs, making him a notable figure in accessible robotics.
