About

Motoyoshi Hasegawa is a pioneering researcher in bio-inspired robotics, with a focused career dedicated to the development of inchworm-type robots for critical rescue missions. His work addresses the urgent need for machines capable of navigating the chaotic, debris-filled environments of collapsed structures following major calamities. Hasegawa’s core contributions lie in the locomotion and self-righting mechanisms of these articulated, limbless robots. He demonstrated that a simple structure—composed of five to six segments connected by pitch and yaw joints—could effectively traverse narrow paths, climb stairs, and even return to an upright position after falling sideways, all without the complexity of legs or wheels. His most cited work, "Study on the gaits of an inchworm robot through a narrow path," has garnered 8 citations, establishing a foundational reference in the field. By proving that vertically undulatory motion is a viable and robust method for mobility in confined spaces, Hasegawa’s research has directly influenced the design of compact, resilient search-and-rescue robots, offering a lifeline in disaster scenarios where finding survivors is a race against time.
