Abstract: This application relates to an actuation system for assistive wearable devices such as exoskeletons designed to actuate a joint of a wearer of the device. The actuation system includes a differential pulley drum having a first drum portion and a second drum portion, the first drum portion and the second drum portion having different radii. The differential pulley drum is located at a first end of the actuator. The actuation system further includes a motor coupled to the differential pulley drum and configured to rotate the differential pulley drum, a second pulley located at a second end of the actuator, a flexible sleeve that extends between the differential pulley drum and the second pulley, and a strand that extends from the differential pulley drum to the second pulley through the flexible sleeve.

Abstract: An exosuit includes a first structure including a series of link elements joined together by joints. The series of link elements extends along a length of the first structure. The joints are configured to flex such that, when the exosuit is worn by a user, the first structure at least partially conforms to a shape of the user's anatomy at a first side of the first structure that extends along the length. The joints restrict flexing that would deform a second side of the first structure extending along the length of the first structure. The exosuit includes a second structure and an actuator coupled to the first structure and the second structure. The actuator causes movement of the first structure relative to the second structure. The exosuit includes an attachment portion to attach the exosuit to the user with the first side of the first structure facing toward the user.
