About

N. Mitumoto is a pioneering figure in the field of microrobotics, with a focused expertise in wireless power transmission and in-pipe locomotion systems. His most influential work, the "In-pipe wireless micro locomotive system" (2003), has garnered 31 citations and introduced a groundbreaking microrobot just 9.5 mm in diameter and 60 mm in length, capable of navigating pipes as small as 10 mm. This system leverages microwaves for both energy supply and command transmission from an outside host, eliminating the need for physical tethering. Mitumoto further advanced this concept in his 2002 study on a "Wireless link system for communication and energy transmission of microrobot" (13 citations), where he successfully integrated a CCD camera, locomotive device, and control circuitry into a fully wireless micromachine. This system transmitted image data and power via microwave and light, marking a significant leap in autonomous microsystems. Mitumoto’s contributions have laid critical groundwork for applications in infrastructure inspection, medical endoscopy, and remote sensing, demonstrating how miniaturization and wireless energy can converge to create self-sufficient robots. His work remains a touchstone for researchers exploring untethered microdevices in constrained environments.
