The invention belongs to the field of joint robots, and particularly relates to a rope-driving multi-joint robot which is used for solving the transmission and arrangement problems of a multi-joint steel wire rope. The rope-driving multi-joint robot comprises hands, wrists, forearms, upper arms, shoulders, a waist and a base, wherein the waist is arranged on the base and is connected with the shoulders through crankshaft assemblies, the shoulders are connected with the upper arms through rotary joint shafts, the upper arms are connected with the forearms through driven gear components II on the rotary joint shafts, the forearms are connected with the wrists through driven gear assemblies I on the rotary joint shafts, the wrists are connected with the hands through the rotary joint shafts, all the parts are connected with one another so as to form a plurality of joints, a rope-driving unit of the joints is connected with one or more than two of the waist, the shoulders, the upper arms, the forearms, the wrists and the hands through flexible ropes, so that the rope-driving multi-joint robot is formed. The robot has eight degrees of freedom in total, and can fully exert the advantages of steel wire rope transmission, such as high transmission precision, and easiness in distribution.
