C. S. George Lee

About

C. S. George Lee is a pioneer in robotics and automation, whose research spans robot dynamics, humanoid locomotion, and socially intelligent robotics. His seminal 1986 work on parallel algorithms for robot inverse dynamics, with 119 citations, established a theoretical time lower bound for computing the Newton-Euler equations, enabling efficient real-time control of multi-link manipulators. Lee has made foundational contributions to bipedal walking, developing model-based feedback controllers that achieve exponential stabilization and global position tracking for fully actuated planar and 3-D humanoid robots. His closed-form inverse kinematic solutions for humanoids, cited 22 times, provide a consistent methodology for joint configuration selection, advancing practical humanoid control. Lee also pioneered mobility-aware ad hoc routing protocols for mobile robot teams (29 citations) and extended cooperative task spaces for dual-arm manipulation. In human-robot interaction, he developed real-time emotion identification systems using NARX neural networks and 3D point-cloud features for pose estimation. His work on lifetime maximization in mobile sensor networks with energy harvesting addresses critical challenges in networked robotics. With over 250 citations across his most-cited papers, Lee’s research has profoundly influenced robot dynamics, humanoid walking, and cognitive robotics, making him a leading figure in the field.
