Hayato Kaetsu

About

Hayato Kaetsu is a robotics researcher whose work has made significant contributions to multi-robot systems, autonomous mobile robotics, and cooperative robot mechanisms. His research spans omnidirectional motion control, swarm robotics, and distributed autonomous systems, with a particular focus on enabling groups of robots to work together intelligently and efficiently. Kaetsu's most influential contribution is his development of a novel omni-directional mobile robot with a 3 DOF decoupling drive mechanism (2002, 198 citations), which elegantly achieved holonomic motion control through three decoupled actuators, eliminating redundancy and simplifying real-world implementation. Alongside this, his pioneering work on self-organizing collective robots with morphogenesis (2002, 108 citations) introduced a compelling vision of swarm robots capable of physical reconfiguration against gravity — a concept with broad implications for adaptive autonomous systems. His research further explored practical challenges in multi-robot coordination, including object transportation without positional data, collision avoidance via infrared sensory systems, and Internet-based teleoperation of robot teams. With over 580 cumulative citations across his top works, Kaetsu's contributions have shaped foundational thinking in cooperative robotics, offering both theoretical frameworks and working prototypes that continue to inform researchers designing intelligent, collaborative robotic systems.
