About

Norihiko Wada is a leading figure in the field of disaster robotics, with a primary focus on developing snake-like rescue robots designed to navigate the treacherous, narrow spaces of collapsed structures. His most significant contribution is the creation of the "KOHGA" series of robots, particularly the KOHGA2, which was engineered to overcome a critical flaw in earlier prototypes: the tendency for obstacles to become caught in the robot's joints, causing it to become stuck. By addressing this stuck avoidance problem, Wada’s work directly enhanced the reliability of robotic search-and-rescue operations. His seminal paper on the KOHGA2, published in 2007, has garnered 71 citations, reflecting its foundational role in the field. Beyond this core achievement, Wada’s research integrates mechanical design, control systems, and practical field testing, making his work essential reading for students and engineers interested in mobile robotics for extreme environments. His contributions continue to influence the design of resilient, articulated robots for hazardous disaster sites.
