Provided is a care robot that assists a standing-upright motion or a sitting motion of a care receiver without making the care receiver uncomfortable. In a care robot 20, a standing-upright trajectory Tas1, along which a movement control portion Ps of a care receiver M1 moves, is set such that a center G of gravity of the care receiver M1 is present in a range A of the soles of both feet between a point in time early after the start of a standing-upright motion and an end time point of the standing-upright motion of the care receiver M1, and a sitting trajectory Tbs1, which is different from the standing-upright trajectory Tas1, and along which the movement control portion Ps of the care receiver M1 moves, is set such that the center G of gravity of the care receiver M1 is present out of the range A of the soles of both feet from a point in time early after the start of a sitting motion of the care receiver M1, and moves toward a predetermined sitting position of the care receiver M1.
