Abstract
Mechanisms to realize lightweight rotational joints having passive, high torque braking in one or more degrees of freedom are presented herein. In addition, robotic systems incorporating one or more rotational joints with passive, high torque braking as described herein are also presented. Each degree of freedom includes a spring element to preload the braking assembly to maintain high torque braking. The force generated by the spring is multiplied to a much larger force applied to the braking elements by a lever structure and an eccentric mechanism. A human user manually displaces the spring element and effectively reduces braking torque to a desired amount. In a further aspect, a two degree of freedom mechanical shoulder joint and brake device is disposed in a structural path between the harness assembly of an upper body support system and a surface of a working environment.
