Abstract: Provided are a robotic hand system and a method for controlling a robotic hand. A robotic hand system operated by a user according to an example embodiment, the robotic hand system may include a robotic hand configured to grip a target object, a first sensor unit disposed on the robotic hand, the first sensor unit configured to detect a real-time posture of the robotic hand, a second sensor unit disposed on the robotic hand, the second sensor unit configured to detect three-dimensional surface information of the target object that appears based on the robotic hand, and a processor configured to infer, based on sensing information of the first sensor unit and the second sensor unit, a motion of the robotic hand conforming to an intention of the user, and operate the robotic hand according to the inferred motion. The robotic hand may include a finger module including a plurality of frames, and one or more joint portions connected to the plurality of frames, the one or more joint portions configured to change positions of the plurality of frames.
