About

Dr. Yunhai Geng is a leading researcher at the intersection of space robotics and rehabilitation exoskeletons, whose work bridges autonomous manipulation in microgravity with human-centered assistive technologies. His most impactful contributions center on advanced control strategies for free-floating space robots, where he has pioneered multi-objective optimization for Cartesian trajectory planning (94 citations) and developed novel fixed-time and predefined-time control frameworks that ensure precise task-space tracking despite the complex dynamics of space environments. His LPV-based offline model predictive control approach (29 citations) offers a computationally efficient solution for real-time applications, enabling more reliable autonomous operations in orbit. In parallel, Dr. Geng has made significant strides in rehabilitation robotics, designing an adaptive knee exoskeleton with a buffering function that mimics the human joint’s instantaneous rotation center (17 citations), and a flexible actuator joint for lower-limb exoskeletons that adjusts stiffness to varying loads and walking speeds. With over 200 cumulative citations, his work is shaping the future of both space exploration and human mobility assistance, demonstrating a rare ability to solve fundamental control challenges across vastly different domains.
