  "abstract": "Provided is a variable stiffness joint structure including a central module, a pressing module that surrounds the central module, and has a grip position in which the central module is radially pressed to block rotation of the central module, and a rotation position in which the central module is released to allow rotation of the central module, and a driving module configured to provide a driving force to move the pressing module from the rotation position to the grip position, wherein the pressing module includes at least one pressing member arranged in a circumferential direction to surround an outer circumferential surface of the central module.",
