Flexible outer limb mechanical arm driven by reconfigurable rope and robot

The invention relates to a flexible outer limb mechanical arm driven by a reconfigurable rope. The flexible outer limb mechanical arm comprises a first bending joint, a second bending joint, a first driving rope set and a second driving rope set. Wherein; the first bending joint and the second bending joint are connected in series, and each of the first bending joint and the second bending joint comprises a mechanical arm unit or at least two mechanical arm units connected in series; one end of each mechanical arm unit is provided with a tenon part, the other end of each mechanical arm unit is provided with a mortise part, and every two adjacent mechanical arm units are connected in series through matching of the tenon parts and the mortise parts. The first driving rope group is connected with the tail end of the first bending joint, and the second driving rope group is connected with the tail end of the second bending joint. A proper number of mechanical arm units can be selected for assembly on site accordi
