The invention discloses a medical care robot. The robot comprises two or above groups of folding components, wherein at least one group of folding components are longitudinally arranged, and at leastone group of folding components are horizontally arranged; each folding component comprises a deformable framework and a driving component; each deformable framework is composed of a plurality of supporting units; in an initial state, all the supporting units are arranged in a straight line, the adjacent supporting units are hinged to each other, and each supporting unit can only rotate upwards relative to the adjacent supporting unit; the driving components can move back and forth along the deformable frameworks, and can drive the relative rotation between certain two adjacent supporting units in the deformable frameworks. According to the medical care robot, a system and a method disclosed by the invention, the plurality of folding components are arranged, the folding position of each folding component can be flexibly adjusted, operations of standing up, sitting, turning over and the like of a user can be realized according to the position in which the user is located, lying of the user in a designated position is not needed, the practicability is relatively high, the use is convenient, and the robot can be operated by both medical staff and the user.
