Abstract

A flexible exosuit includes rigid and flexible elements configured to couple forces to a body of a wearer. Further, the flexible exosuit includes flexible linear actuators and clutched compliance elements to apply and/or modulate forces and/or compliances between segments of the body of the wearer. The flexible exosuit further includes electronic controllers, power sources and sensors. The flexible exosuit can be configured to apply forces to the body of the wearer to enable a variety of applications. In some examples, the flexible exosuit can be configured to augment the physical strength or endurance of the wearer. In some examples, the flexible exosuit can be configured to train the wearer to perform certain physical tasks. In some examples, the flexible exosuit can be configured to record physical activities of the wearer.

Claims

1-24. -24. (canceled)

25. A platform for body augmentation, comprising:

a flexible suit configured to be worn over at least a portion of a human body;

a selection of electronically operable actuators coupled to the flexible suit;

a selection of sensors disposed in the flexible suit and configured to provide information relating to the operation of the platform for body augmentation;

a control system disposed in the flexible suit, wherein the control system is configured to electronically operate the actuators using the information provided by the sensors in a plurality of different ways to provide a plurality of different modes of operation.

26. The platform for body augmentation of claim 25, wherein the plurality of different modes of operation relate to one or more of walking, running, jumping, lifting, load carrying, climbing, cycling, exercising, training, controlling a virtual avatar, and controlling a tele-robotic system.

27. The platform for body augmentation of claim 25, where in the selection of electronically operable actuators comprises one or more flexible linear actuators and one or more clutched-compliance elements.

28. The platform for body augmentation of claim 25, wherein the control system is configured to execute any of a plurality of stored computer-readable programs, wherein execution of a stored computer-readable program by the control system comprises operating the actuators using the information provided by the sensors in accordance with the stored computer-readable program, and wherein each of the stored computer-readable programs defines at least one of the plurality of different modes of operation.

29. The platform for body augmentation of claim 28, wherein the control system is configured to determine a configuration of electronically operable actuators coupled to the flexible suit and sensors disposed in the flexible suit;

and wherein operating the actuators using the information provided by the sensors in accordance with the stored computer-readable program further comprises operating the actuators using the information provided by the sensors in accordance with the determined configuration of electronically operable actuators coupled to the flexible suit and sensors disposed in the flexible suit.
