Working method of nursing robot

The invention provides a working method of a nursing robot, which comprises the following specific steps: (1) when a self-service shifting nursing robot needs to be used, a control system controls the self-service shifting nursing robot to move to the front of a patient; (2) according to the sitting position of the patient, a first-stage lifting device of the lifting device lifts out to rotate a swing rod towards the patient, and then the position of the chest bracket is adjusted through a second-stage lifting device, so that the position height of the chest bracket is matched with the position height of the upper body of the patient; (3) the lifting devices are controlled, so that the first-stage lifting device shrinks at the speed of v1 and pulls the swing rod to rotate, and meanwhile, the second-stage lifting device shrinks at the speed of v2 and drives the chest support bracket to slowly rotate forwards and upwards, so that the patient is supported, and the supporting action is completed; and (4) the chas
