About
Satoshi Otsuki is a leading researcher in humanoid robotics, specializing in the development of high-performance actuation systems that combine power, durability, and force sensitivity. His most impactful work centers on the design and application of linear electro-hydrostatic actuators (EHAs), a technology that enables robots to achieve both high-power output and backdrivability—a critical combination for safe, dynamic locomotion and dexterous manipulation. In his highly cited 2014 paper (30 citations), Otsuki introduced a novel EHA that overcomes the traditional trade-off between strength and force sensitivity, paving the way for more resilient humanoid robots. He further advanced the field by designing an integrated ankle-knee joint system for humanoids, featuring a parallel ankle mechanism driven by these actuators and redundant biarticular actuators, as detailed in his 2013 work (7 citations). This architecture enhances impact resistance and adaptability, supporting the hypothesis that force-sensitive legged mechanisms can fundamentally improve locomotion by treating it as a manipulation of the center of mass. Otsuki’s contributions are instrumental in bridging the gap between theoretical biomechanics and practical robot hardware, offering a robust foundation for the next generation of agile, human-like machines.
