摘要： An exoskeleton device that includes an artificial joint and a frame member extending from the artificial joint. The frame member is configured for extension over a limb of a user. The exoskeleton device also includes a self-aligning mechanism connected to the frame member. The self-aligning mechanism includes three passive degrees of freedom (pDOF) provided in a prismatic-revolute-revolute (PRR) configuration. The self-aligning mechanism also includes a limb attachment member configured for mechanically coupling to a portion of the limb of the user.

摘要： Disclosed is a lightweight powered ankle exoskeleton with integrated series-elastic actuation capable of providing high torque and power densities while maintaining a compact and lightweight profile. The exoskeleton includes: a frame configured to be worn adjacent a lower leg of a user; a power transmission assembly integrated with the frame and configured to deliver torque to a crank member to rotate the crank member about an ankle joint; and a foot/shoe interface coupled to the crank member and configured to interface with a foot or shoe of the user and to transmit torque generated at the ankle joint to the foot or shoe of the user.
