The invention discloses a rope-driven waist rehabilitation robot. The robot comprises a frame, a gravity balance unit, rope winding and unwinding units, a rope-driven rehabilitation exercise unit and a control unit, wherein the rope-driven rehabilitation exercise unit comprises a rehabilitation waist belt, pulling ropes and a guide pulley; the rehabilitation waist belt is at least connected with six pulling ropes; each pulling rope corresponds to one rope winding and unwinding unit; and the control unit controls the length change of the corresponding pulling rope by controlling each rope winding and unwinding unit so as to drive the waist of a rehabilitation patient to move along a pelvic movement track of a normal person during walking. Therefore, aiming at the problem of a coordination control mode of controlling the pelvic movement track of the rehabilitation patient in the rehabilitation training process, the rehabilitation patient can move along the pelvic movement track of the normal person under standing and walking conditions through the coordinated action of a set of gravity balance unit and a plurality of pulling ropes so as to achieve an effective waist rehabilitation training effect; and the robot can perform configuration change and rehabilitation training amplitude and strength adjustment according to the disease condition and individual difference of the rehabilitation patient.
