About

Garth Zeglin is a robotics researcher whose work spans legged locomotion, dynamic control, and robotic manipulation. He is best known for pioneering the **bow leg hopping robot**, a landmark contribution to mobile robotics that introduced a novel, highly resilient leg design inspired by an archer's bow. This work, which garnered over 260 combined citations across two foundational papers, demonstrated how passive mechanical properties could be elegantly exploited to achieve efficient, controllable hopping locomotion — a philosophy that runs throughout his career. Zeglin's contributions extend into bipedal walking, where he developed minimax differential dynamic programming for robust control in high-dimensional spaces (120 citations) and proposed influential reinforcement learning algorithms enabling robots to learn stable walking patterns from experience. His work on passive dynamic walkers, including the use of ankle springs as biomechanically realistic alternatives to arc-shaped feet, further reflects his commitment to human-inspired, energy-efficient design. More recently, Zeglin has ventured into architectural robotics, exploring robotic concrete surface finishing for thermally tuned building components. His early undergraduate thesis on the Uniroo one-legged hopper (1991, 72 citations) foreshadowed a career defined by creative mechanical insight and cross-disciplinary innovation in robot locomotion and manipulation.
