摘要：
A joint torque augmentation system includes linkage assembly configured to couple to a user. Linkage assembly includes a unidirectional link and a device joint. The linkage assembly is worn by a user or is configured to couple to footwear. An actuator is coupled to the linkage assembly to provide a torque at a joint of the user. A sensor is coupled to the user to measure a position of the user. A control system is coupled to the sensor and actuator. A phase of gait for the user is determined by the control system based on the position measured by the sensor. The actuator produces a tension force on the linkage assembly during a first phase of gait. A compliant element is coupled between the actuator and linkage assembly. The compliant element is tuned based on a load carried by the user.
