Abstract:
A walking assist device including a waist assembly and at least one leg assembly connected to the waist assembly is provided. The leg assembly includes a thigh stand, a shank stand, a sole, a hip joint, a knee joint and an ankle joint. The hip joint is pivoted to the thigh. The knee joint is pivoted to the thigh stand and connected to the shank stand. The ankle joint includes at least a flexible plate and an elastic member. The flexible plate includes a first end and a second end opposite to each other. The first end is pivoted to the shank stand directly or indirectly, the second end is connected to the sole, and the elastic member presses the first end of the flexible plate.
Abstract:
A method for estimating posture of robotic walking aid comprises: providing a motor controller, a motor encoder and a motor on right and left hip joints, and right and left knee joints of a robotic walking aid, providing an inertial sensor on upper body of the robotic walking aid, wherein the motor controller, the motor encoder, the motor and the inertial sensor are coupled to a control unit; installing the robotic walking aid on a user; inputting the lengths of the upper body, two thighs, two shanks, two feet of the robotic walking aid to the control unit, wherein the upper body, two thighs, two shanks, two feet form a plurality of points; obtaining an angle of the upper body corresponding to a reference frame with the inertial sensor; obtaining angles of those joints with those motor encoders; and calculating 3 dimensional coordinates of each point with a motion model.
Abstract:
