Patent 8419096 was granted and assigned to Samsung on April, 2013 by the United States Patent and Trademark Office.
A robot hand may have an improved structure so that movements of some of joints of a finger structure do not influence operations of other joints. A meta phalangeal (MP) roll joint unit rotated in a roll direction and an MP pitch joint unit rotated in a pitch direction of an MP joint unit are separately arranged to form an offset. Movable angles of the respective joint units are widened, and the joint units are precisely controlled. Overall friction within the robot hand is reduced, and a robot having the hand is stabilized.
