Abstract
The present invention relates to a variable rigidity robot joint system including a first driving module and a second driving module generating torque which is rotated on a first direction, a first rotating module changing rotations of the first driving module and the second driving module into rotations on a second direction intersecting the first direction when the first and second driving modules rotate in directions in which a joint is rotated in a same direction, thereby rotating the joint, a rigidity-providing member providing rigidity by elastically supporting a rotational movement of the first rotating module on the second direction, and a second rotating module changing rotations of the first driving module and the second driving module into a linear motion in the first direction when the first and second driving modules rotate in directions in which the joint is rotated in different directions.
