About

Elias Brassitos is a robotics and mechanical engineering researcher whose work centers on the design and development of advanced actuation systems for robotic and space applications. He is best known for pioneering research on the Gear Bearing Drive, a novel compact actuator concept developed in collaboration with NASA that eliminates the need for a planetary carrier and individual planet bearings, offering significant advantages in weight, complexity, and performance over conventional transmission systems. His 2017 paper on high-torque robotic actuators for space mechanisms stands as his most influential contribution with 23 citations, addressing the critical need for compact joint drive systems capable of delivering high torques in demanding space environments. Across a sustained body of work spanning from 2013 to 2020, Brassitos has systematically advanced the kinematics, dynamics, and practical design methodology of gear bearing technology, demonstrating its applicability to planetary rovers, space manipulators, and commercial robotics. His research consistently addresses real-world engineering challenges — balancing high torque density, torsional stiffness, lightweight construction, and cost-effectiveness — making his contributions particularly valuable to the next generation of space exploration and advanced robotic systems.
