The invention discloses a capsule type biopsy robot driven by an external magnetic field, and belongs to the technical field of micro medical robots. The capsule endoscope robot aims at solving the problem that an existing capsule endoscope robot can only carry out image collection and cannot carry out tissue sampling. Comprising a robot body and an external magnetic field module, the robot body comprises a shell, an image acquisition module, a biopsy module and an internal magnetic drive module, the biopsy module and the internal magnetic drive module are arranged in an inner cavity of the shell, and the external magnetic field module is arranged outside the shell; the inner magnetic drive module and the outer magnetic field module are matched with each other to drive the robot body to move in the axial direction of the shell and rotate or swing in the circumferential direction of the shell, and tissue in a biopsy body is picked up through the biopsy module; and the image acquisition module is arranged in th
