Systems and Methods for Gravitational Load Support

摘要

A load support device includes a first link coupled to a load. A second link is configured to couple to footwear. The second link is pivotally coupled to the first link. The first and second link comprise a link assembly. A first compliant member is disposed between the load and the second link. The first compliant member includes a tension spring or a compression spring. The link assembly further includes a tension cable coupled to the first compliant member. A first actuator is coupled to the first compliant member to control a stiffness of the first compliant member. A sensor is configured to couple to a user to measure a physical state of the user. A control system controls the first actuator based on a gait activity. The first actuator is actuated based on the physical state of the user. The load support device is tuned based on the load.
