EXTENDABLE WEARABLE ROBOT SYSTEM

WIPO Patent Application WO/2021/002662

A1

An extendable wearable robot system of the present invention, which is applied to a walking automation robot system (1), comprises a robot weight support (RWS) (130) capable of reducing robot's weight and assisting up and down movement, with a counter-balancing effect of 1-axis motion by a vertical spring, and a 2-axis motion supporter (140) capable of voluntarily moving left and right through stabilization of movement of center of gravity by translational motion of 2-axis motion by a horizontal spring, and thereby, during a walking motion of a wearable robot (1-1), providing effects of counter-balancing/reverse force minimization/translational motion/stabilization of center of gravity/size adjustment, in particular, reducing manufacturing costs and simplifying a structure, compared to existing actuator equipment by applying, to the effects of the RWS (130) and the 2-axis motion supporter (140), a spring for assisting the up and down/left and right movement through a change in an elastic modulus.
