Abstract: A string actuator-based exoskeleton robot includes: a driving force conversion unit including a fixed frame and a rotation pulley and mountable on a side portion of the waist of a human body; a driving unit including a driving motor providing a driving force and a pair of strings provided in double rows to have one side connected to the driving motor and the other side connected to the rotation pulley, and assisting the rotation of the rotation pulley by twisting or untwisting the pair of strings with or from each other by a rotational driving force of the driving motor to vary a length of the pair of strings; and a support unit formed to extend from the rotation pulley to at least one of a front surface or a rear surface of the femoral region of the human body to support the femoral region of the human body.
