About

Morizo Hemmi is a pioneering robotics engineer whose work focuses on developing tough, hydraulic-driven robots capable of operating in extreme and unpredictable environments—such as disaster zones. His core research areas include hydraulic actuator design, lightweight materials, and high-power-density robotic systems. Hemmi’s major contributions lie in overcoming the fragility of conventional electromagnetic motors by engineering hydraulic actuators that offer superior shock resistance, backdrivability, and power-to-weight ratios. Notably, he demonstrated the use of multi-directional forged magnesium alloy to create super-low-friction, lightweight hydraulic cylinders, which he applied to a robotic leg. His most cited works—each garnering 7 citations—include “Super-low friction and lightweight hydraulic cylinder…” (2018), “New Hydraulic Components for Tough Robots” (2019), and “Development of Hydraulic Tough Motors with High Power Density…” (2019), the latter featuring a 7-axis robotic arm. These papers collectively advance the vision of robots that can withstand large shocks, degraded communications, and other critical failures. Hemmi’s research is instrumental in bridging the gap between industrial hydraulic machinery and agile, resilient robotics, making him a key figure in the pursuit of truly tough, field-ready robots.
