About

Hidehiko Nakajo is a pioneering roboticist whose work bridges the gap between extreme environment exploration and bio-inspired engineering. His primary research focuses on developing novel robotic systems for deep-seafloor excavation and sub-seafloor sampling, with a particular emphasis on peristaltic crawling mechanisms and hydraulic artificial muscles. Nakajo’s most significant contribution is the creation of a hydraulic artificial muscle specifically designed for a deep-seafloor excavation robot, a breakthrough that enables robust, flexible movement in high-pressure, low-visibility underwater environments. This innovation, detailed in his 2015 paper which has garnered 9 citations, directly addresses the critical need for reliable sampling of mud and marine sediments—resources vital for biological, geological, and mineral studies. By mimicking the peristaltic motion of earthworms, Nakajo’s robot can navigate and excavate sub-seafloor terrain with unprecedented efficiency, offering a non-destructive method to access potentially valuable mineral resources and marine sediments. His work not only advances deep-sea exploration technology but also lays the groundwork for future autonomous sampling missions, making him a key figure in the field of extreme environment robotics.
