About

Tetsuaki Nagano is a pioneering researcher in the field of robotics and control systems, with a particular focus on dynamic locomotion and hybrid systems. His work centers on the intersection of optimal control theory and robotic motion, especially in scenarios involving contact and impact dynamics. Nagano’s most notable contribution is the development of a linear 1-degree-of-freedom trampoline robot, which he introduced in his highly cited 2003 paper. In this work, he proposed an innovative hybrid optimal control approach, modeling the robot’s bouncing behavior through a linear complementarity system framework. By applying a differential dynamic programming-based algorithm, he successfully solved the high-jump control problem, demonstrating how robots can achieve efficient, dynamic motion through contact-rich environments. This research has garnered 6 citations, reflecting its influence on subsequent studies in legged locomotion and impact-aware control. Nagano’s work is particularly valuable for students and researchers interested in optimal control, hybrid systems, and the practical challenges of robotic jumping and dynamic maneuvers.
