An exoskeleton ( 100) configured to be coupled to a per-son
(187) includes an exoskeleton trunk (109) and leg supports (101, 102)
adapted to contact the ground. Hip torque generators ( 145, 146) extend
between the exoskeleton trunk (109) and respective leg supports (101,
102). A load holding mechanism (221 ) is rotatably coupled to the ex-oskeleton

trunk (109), preferably via over-shoulder members (138) con-figured
to support a load (154) in front of the person (187). In use, hip
torque generators (145, 146) create torque between the exoskeleton trunk
(109) and respective leg supports (101, 102) in the stance phase, wherein
at least one torque generator (145 or 146) is configured to create a first
torque between the exoskeleton trunk (109) and one of the first and sec-ond
leg supports (101, 102) in the stance phase opposing a second torque
generated on the exoskeleton ( 100) by a weight of the load (154). Load
bearing sensors (236, 303) may be utilized to determine the torque gener-ated
by the load (154) and communicate with a controller (137) to control
power to the torque generators (145, 146).

Abrégé

A lower extremity exoskeleton (100) includes: at least one power unit (201); two leg supports (101, 102) designed to rest on the ground (130); two knee joints (107, 108) configured to allow flexion and extension between respective shank (105, 106) and thigh links (103, 104) of the leg supports (101, 102); an exoskeleton trunk (109) rotatably connectable to the leg supports (101, 102); and two hip actuators (145, 146) configured to create torques between the exoskeleton trunk (109) and the leg supports (101, 102). In use, the hip actuators (145, 146) create a torque to move the leg supports (101, 102) backward relative to the exoskeleton trunk ( 109) during a stance phase, which pushes the exoskeleton trunk (109) forward. A second torque may be used to move the leg supports (101, 102) forward relative to the exoskeleton trunk (109) into a swing phase. Additionally, a swing torque may be generated during the swing phase to move the leg support (101, 102) forward relative to the exoskeleton trunk (109). This results in decreased oxygen consumption and heart rate of a user wearing the exoskeleton (100).
