Abstract

<p>The authors have developed A variable viscoelastic joint that mimics the principle of human joint drive and uses a pneumatic artificial muscle with an antagonistic arrangement and a magnetic viscous fluid brake. In this paper, the versatility of this joint was improved by modularizing this joint. The variable viscoelastic joint module is the world's first pneumatic drive module with a variable viscoelastic characteristic that includes a power source inside the device. We believe that the development of this device will make it easier to manufacture robots that are lighter, safer and easier to maintain than robots that use motors and reduction gears, and will operate at lower cost.</p>
