New Hydraulic Actuator Will Make Robots Tougher

This figure shows a seven-axis hydraulic robot arm breaking concrete slabs, each 30 mm thick. This is a prototype for comparison with a four-legged robot also being developed in this project by Waseda University, Meiji University, and others, produced at approximately the same size. It consists of seven of the new hydraulic motors.

Researchers at Tokyo Institute of Technology (Tokyo Tech) have developed a hydraulic actuator[1] that will allow tough robots to operate in disaster sites and other harsh environments. Tokyo Tech Venture H-MUSCLE Corporation?has been established to pursue applications for the actuator, and shipping of product
