Design of a New Bio-Inspired Actuator for Biomimetic Robots

Abstract

Human-machine intelligent integration of wearable robots such as prostheses and exoskeletons will be a key future robot industry development trend, with significant implications for supporting medical rehabilitation, expanding the boundaries of human sports, and boosting societal welfare. This research presents a novel actuator that replicates the driving principle and structure of human muscles in order to increase the load capacity of wearable robots while lowering their size and weight. Better power density and energy efficiency result in a higher load capacity, more compact construction, lower weight, and longer service life for the actuator system. The hydraulic actuator has a higher driving force and power density than the electric actuator or the new flexible actuator. The bionic hydraulic actuator system has emerged as a significant study area in bionic robotics.
