摘要： A method and apparatus for assisting walking of a user is provided. Information related to a motion of a user wearing a walking assistance apparatus is measured by an inertial measurement unit (IMU), a gait phase of the user corresponding to the measured information is predicted using data learned in advance through machine learning, an assistance torque to be provided to the user is determined based on the predicted gait phase, and a driver is controlled to output the assistance torque.

摘要： A method for controlling an ankle-type walking assistance device may include measuring an angle of a joint of the walking assistance apparatus, calculating an angular velocity and a linear velocity of a frame of the walking assistance device using an inertial measurement unit (IMU) attached to the frame, generating a dynamics model for the walking assistance device based on the angle of the joint, the angular velocity and the linear velocity of the frame, calculating a disturbance applied to the walking assistance device based on the dynamics model, and controlling the walking assistance device based on the calculated force, equivalent, or wrench.

摘要： A force transmitting frame may have a length greater than a width. Stiffnesses of first and second end portions of the force transmitting frame may be greater than a stiffness of a central area of the force transmitting frame in a longitudinal direction of the force transmitting frame. The force transmitting frame may include: an inner frame configured to support one side of a user; and/or an outer frame of which first and second end portions are fixed to first and second end portions of the inner frame, and of which a central portion is not fixed to a central portion of the inner frame. The central portion of the outer frame may be configured to slide with respect to the central portion of the inner frame.
