    摘要: An exoskeleton device is disclosed. The exoskeleton device comprises a Bowden cable, a shank portion comprising a strut, and a foot portion coupled to the shank portion by a rotational joint. The foot portion comprises a heel lever and a pulley attached to the heel lever, wherein the strut of the shank portion is configured to redirect the Bowden cable toward the pulley, wherein the pulley is configured to redirect the Bowden cable back toward the shank portion, and wherein the Bowden cable is configured to generate torque by pulling the pulley. The exoskeleton device further comprises a midsole, wherein the midsole is releasably coupled to the lever, and wherein the midsole is configured to transmit force to a foot of a user.

    摘要: An active orthotic device, e.g. a hand orthosis, is attached to one or more limbs of a human subject and comprises a respective set of actuators (21) for moving a respective limb (1A) among the one or more limbs. A method for controlling the orthotic device comprises obtaining one or more bioelectric signals, [S(t)], from one or more bioelectric sensors (10) attached to or implanted in the human subject; processing the one or more bioelectric signals, [5(t)j, for prediction of an intended application force, FA(t), of the respective limb (1A) onto an object; obtaining a force signal, PA(t), from a force sensing device (22) associated with the respective set of actuators (21) and/or the respective limb (1A); and generating, as a function of a momentary difference, e(t), between the intended application force, FA(t), and the force signal, PA(t), a respective set of control signals, it(t), for the respective set of actuators (21).

    摘要: An exoskeleton wearable on a body of a human having two legs, the exoskeleton comprising a first HAA joint and a second HAA joint to assist the human with leg abduction and adduction movements that are parallel to a frontal plane, each of the first and the second HAA joints having an actuator, each actuator including a motor and a clutch. The exoskeleton further comprises a sensor system for measuring a combined center of mass of the human and the exoskeleton in the frontal plane and a step width of the human in the frontal plane. The exoskeleton further comprises a controller that outputs adjustment angles for each of the first and the second HAA joints based on the center of mass and the step width. The first and the second HAA joints are respectively rotated based on the respective output adjustment angles.
