About

Shigetaka Kojima is a pioneering roboticist whose research centers on bio-inspired locomotion and control systems, particularly the development of brachiation robots—machines that mimic the swinging locomotion of gibbons. His major contributions include the design of controllers based on virtual holonomic constraints, enabling energy-efficient and stable brachiation across both uniform and irregular ladders. Kojima’s work addresses the challenge of achieving continuous, dynamic locomotion by decomposing motion into swing-back and locomotion phases, with a focus on energy optimization. His most cited paper, “Design method of brachiation controller based on virtual holonomic constraint” (2007, 17 citations), lays the theoretical foundation for this approach, while subsequent studies extend it to irregular environments, demonstrating adaptability. Notably, Kojima also ventured into field robotics with the “Development of Surveying Robot” (1996), showcasing his versatility in automating labor-intensive tasks. With a cumulative citation count reflecting steady influence, Kojima’s research has inspired advancements in underactuated robotics and nonlinear control, making him a key figure in the study of agile, animal-like locomotion for autonomous systems.
