A robotic arm is for holding a molding item. The robotic arm includes a mount; a lifting mechanism mounted to the mount; a horizontal driving device; a rotating assembly mounted between the lifting mechanism and the horizontal driving device to rotate the horizontal driving device relative to the lifting mechanism; a holder for holding the molding item, the holder mounted on the horizontal driving device. The lifting mechanism cause the holder to move relative to the mount in a first direction, the horizontal driving device moves the holder relative to the mount and the lifting mechanism in a second direction perpendicular to the first direction.
