The present invention relates to a hydraulic system for supplying a hydraulic pressure so as to operate a wearable robot, which comprises: a tank unit; a first hydraulic pump unit and a second hydraulic pump unit, arranged at the left and right tank respectively so as to supply the actuator of the wearable robot by sucking each hydraulic oil from the tank; a connection unit for connecting to the actuator for the hydraulic oil sucked from the tank unit operated by at least one of the operations of the first hydraulic pump unit and the second hydraulic pump unit; a first servo motor unit, arranged at the left and right side of the tank, and arranged at each upper portion of the first hydraulic pump unit and the second hydraulic pump unit so as to operate the first hydraulic pump unit and the second hydraulic pump unit respectively; and a hydraulic control unit to control a first servo motor and a second servo motor, wherein at least one of the first hydraulic pump unit and the second hydraulic pump unit is to be operated so as to supply hydraulic oil of the tank unit to the connection unit, and to control the connection unit so as to connect the hydraulic oil supplying to the connection unit then to the actuator. To this end, the present invention, compared to the high power of the motor, can reduce the risk of damage affecting the human body when a trouble occurs, and the load can be distributed by the distributed placement of the motor so that the burden of design considering the center of gravity can be reduced. |
