About

Kenichi Saruwatari’s research focuses on the intersection of advanced polymer tribology and humanoid robotics, specifically addressing the critical challenge of wear and mechanical reliability in robot joint systems. His work centers on developing durable, lightweight transmission components using reinforced poly-ether-ether-ketone (PEEK) composites—materials that combine toughness with reduced weight for biped walking robots. Saruwatari’s major contributions include systematic investigations into how wear, thermal deformation, and backlash affect machined PEEK bushes when paired with metal counterparts like titanium crankshafts and 7075 aluminum alloy cam plates. His 2012 study on PEEK bush and Ti crank shaft wear (5 citations) established foundational insights into joint durability under high torque, while his 2013 work on PEEK against aluminum alloy (4 citations) explored the role of PTFE, graphite, and carbon fiber reinforcements in reducing friction and transmission error. Collectively, his papers (totaling 12+ citations) provide essential design guidelines for polymer-based transmission parts in humanoid robots, balancing material selection with long-term performance. Saruwatari’s research is notable for bridging materials science and robotics engineering, offering practical solutions for next-generation, lightweight robotic joints.
