About

Kohei Tatsumi is a robotics researcher whose work focuses on advancing the mobility and stability of wheeled robots in challenging urban environments, particularly for step-climbing and obstacle negotiation. His most significant contribution is the design and analysis of a minimalist step-climbing robot, which uses a simple yet effective mechanism—varying the center distance between its front and rear wheels—to ascend stairs without complex appendages. This work, published in 2021, has garnered 22 citations, reflecting its impact on simplifying robotic locomotion. Tatsumi further addresses a critical limitation in such designs by developing an anti-slip mechanism for wheels, actuated by shape memory alloy (SMA) and inspired by the Lazy Tong and bi-stable four-bar linkage. This mechanism clamps onto stair edges to prevent slippage, enhancing reliability during ascent. With 6 citations, this work demonstrates his commitment to solving practical, real-world challenges in robotics. Tatsumi’s research bridges minimalism and functionality, offering elegant solutions that could enable more accessible and robust robots for search-and-rescue, delivery, or assistive applications. His innovative use of smart materials and clever mechanical design marks him as a promising figure in field robotics.
