A care robot comprising: a base that travels along a first axis direction using a first drive section; a robot arm section that is provided on the base and includes a second drive axis (22b2) and a third drive axis which are independently driven by a second drive section (22b3) and a third drive section (22a2b), wherein at least one of the second drive axis (22b2) and the third drive axis is a rotation drive axis (22b2) that is rotated around a rotation axis extending in a horizontal direction by the second drive section (22b3); a holding section that is provided on an end of the robot arm section, rotates around the rotation drive axis (22b2), and assists a care receiver to stand up or sit down by supporting a body part of the care receiver; a storage section that stores standing up trajectory reference data which indicates the standing up trajectory along which a movement control portion (Ps) of the care receiver passes when the care receiver sitting on a seat stands up being supported by the holding section, and sitting down trajectory reference data which indicates the sitting down trajectory along which a movement control portion (Ps) of the care receiver passes when the stood up care receiver sits down being supported by the holding section; and a drive control section that controls the first drive section so as to move the base along the first axis direction, and simultaneously controls the second drive section (22b3) and the third drive section (22a2b) so as to change the shape of the robot arm section, based on the standing up trajectory reference data and the sitting down trajectory reference data. a base that travels along a first axis direction using a first drive section; a robot arm section that is provided on the base and includes a second drive axis (22b2) and a third drive axis which are independently driven by a second drive section (22b3) and a third drive section (22a2b), wherein at least one of the second drive axis (22b2) and the third drive axis is a rotation drive axis (22b2) that is rotated around a rotation axis extending in a horizontal direction by the second drive section (22b3); a holding section that is provided on an end of the robot arm section, rotates around the rotation drive axis (22b2), and assists a care receiver to stand up or sit down by supporting a body part of the care receiver; a storage section that stores standing up trajectory reference data which indicates the standing up trajectory along which a movement control portion (Ps) of the care receiver passes when the care receiver sitting on a seat stands up being supported by the holding section, and sitting down trajectory reference data which indicates the sitting down trajectory along which a movement control portion (Ps) of the care receiver passes when the stood up care receiver sits down being supported by the holding section; and a drive control section that controls the first drive section so as to move the base along the first axis direction, and simultaneously controls the second drive section (22b3) and the third drive section (22a2b) so as to change the shape of the robot arm section, based on the standing up trajectory reference data and the sitting down trajectory reference data.
