About
Hitonobu Koike is a researcher specializing in the tribology and mechanical design of lightweight, durable joint components for humanoid robots. His work focuses on the use of advanced polymer materials, particularly poly-ether-ether-ketone (PEEK) composites, to replace traditional metal parts in robotic joints. Koike’s major contributions include systematic investigations into the wear behavior, thermal deformation, and transmission error of PEEK bushes sliding against titanium and 7075 aluminum alloy counterparts. He has demonstrated how reinforced PEEK (containing PTFE, graphite, and carbon fibers) can reduce weight while maintaining toughness and compressive durability under high torque and cyclic loads—critical for biped walking robots. His studies on backlash and fatigue wear under middle-load conditions provide practical guidelines for designing compact, low-maintenance joint elements. Although his citation counts (ranging from 3 to 8 per paper) reflect a niche but focused impact, his work is foundational for engineers developing tall humanoid robots where joint reliability and lightweight construction are paramount. Koike’s research bridges materials science and robotics, offering data-driven solutions for real-world joint performance.
