Sajid Nisar

About

Sajid Nisar is a robotics and biomedical engineering researcher whose work sits at the intersection of surgical robotics, haptic feedback systems, and minimally invasive surgery. He is best known for his contributions to the development of telesurgical robotic systems, most notably the Al-Zahrawi platform, a landmark system designed to enhance surgical precision and dexterity in remote operative settings, which has garnered 31 citations since its 2014 publication. His research has consistently addressed critical gaps in surgical robotics, including the design of remote center of motion mechanisms with optimized spatial footprints, robotic manipulators with replaceable surgical tools, and the integration of haptic feedback to restore tactile sensation for surgeons — a longstanding limitation in commercially available systems. Nisar has also explored wearable kinesthetic haptic devices and advanced grasp detection using point cloud data, reflecting a broadening scope toward human-robot interaction and autonomous systems. His innovative "Kraken-Gear" mechanism demonstrates a forward-looking interest in additive manufacturing for lightweight robotic applications. With over 100 cumulative citations across his portfolio, Nisar's work has meaningfully shaped the design principles and engineering challenges driving next-generation surgical robotics.
