Abstract: In a state where a drive unit is located on a lateral side of a joint(s) of a wearer wearing clothes and a communication unit and a frame unit are fixed and retained corresponding to the wearer's first and second body sites, respectively, a driving torque of an actuator according to movements of the wearer's joint is transmitted as an assist force to the first and second body sites without giving any physical burdens or hindrances in daily life to the wearer.

Abstract: Provided is a walking aid device capable of easily offering walking training by aiding the oscillation of the user's pelvis. The walking aid device comprises a drive part which supports each of at least two or more locations of the user's lumbar region, and applies external force independently to each of the supported locations; a gait recognition unit which recognizes the user's gait; and a control unit which sets the user's ideal walking motion pattern based on a recognition result of the gait recognition unit, and controls the external force applied by the drive part to each of the locations of the lumbar region so that the user's pelvis position within the lumbar region will oscillate to match the walking motion pattern.

Abstract: A wearable action-assistance device includes a hip frame to be worn on hips of a wearer, a lower limb frame to be worn on a lower limb of the wearer, a plurality of drive portions provided on the lower limb frame to correspond to joints of the wearer and configured to generate an assistive force on joints of the wearer, a control portion that controls the drive portions based on a signal caused by an action of the wearer, and an operable operation unit provided near the hip frame. The operation unit includes a plurality of operation buttons corresponding to the respective joints for setting an assistive force to joints of the wearer at the plurality of drive portions. The plurality of operation buttons is, when viewed from a back face side of the hip frame, arranged to correspond to a positional relationship between the drive portions.

Abstract: A wearable action-assistance device includes a hip frame that is capable of being worn on hips of a wearer, a lower limb frame that is capable of being worn on a lower limb of the wearer, a plurality of drive portions provided on the lower limb frame in correspondence with joints of the wearer, and a control portion that controls the drive portions based on a signal that is caused by an action of the wearer. The lower limb frame has a variable shape portion that can bend a portion other than the drive portions to left and right to adjust a flexion angle thereof.
