About

Stepan Pchelkin is a robotics researcher whose work bridges the gap between theoretical control theory and practical robot motion, with a particular focus on industrial manipulators and bio-inspired locomotion. His key research areas include orbital stabilization, trajectory planning, and human-robot motion coordination. Pchelkin’s most cited work (26 citations) explores orbital stabilization as an alternative to classical asymptotic control for industrial robot arms, demonstrating performance improvements using modified PD+ and inverse dynamics controllers—a contribution that offers engineers a more robust framework for repetitive tasks. He has also made notable strides in humanoid robotics, planning natural sit-down and chair-rise motions that replicate human movement dynamics (13 citations), and in integrated time-optimal trajectory planning for industrial manipulators (9 citations). Beyond humanoids, Pchelkin has ventured into bio-inspired robotics, shaping energetically efficient brachiation (swinging) motions for a 24-DOF gorilla robot (6 citations) and developing algorithms for finding gaits in locomotive mechanisms (5 citations). His work is characterized by a systematic approach to motion coordination, as seen in his analysis of dynamic human motion (8 citations), and has practical implications for manufacturing, rehabilitation, and animal-like robots. With a citation count spanning over a decade, Pchelkin’s research continues to influence both industrial automation and legged locomotion design.
