Provided are an upper limb rehabilitation robot including: a sensing member that is mounted and fixed to an upper limb of a user and captures motion of the upper limb according to a movement intention of the user; a motion control unit that is electrically connected to the sensing member, calculates a movement direction, a distance or angle, a speed, and an auxiliary force (target value) needed for the upper limb to move, intended by the upper limb, based on the motion captured by using the sensing member, and generates and outputs a control signal according to the calculated movement direction, distance or angle, speed, and auxiliary force (target value); and a multi-joint robot, to an end of an arm of which the sensing member is coupled, wherein the multi-joint robot guides movement of the upper limb fixed to the sensing member to selectively move or rotate toward a food tray placed at a designated position of a table along an X-axis, a Y-axis, or a Z-axis and provides an assistance force to the upper limb.
