Magnetic resonance imaging (MRI) is better than other imaging equipment in detecting tumors, and navigation for robotic breast intervention biopsy. However, material requirements for robots driving devices are demanding incredibly because of the environment. Given this problem, a novel double cable-conduit driving method is put forward in this paper, which can be used in MRI for breast intervention robots. Besides, lebus grooves are adopted to the driving wheels, which enable the system to realize remote-range and large-scale driving on the premise that the precision can be further enhanced. The driving characteristic of the novel cable-conduit is established. Moreover, the cable-conduit experimental data proves the results of theoretical deduction. Finally, the cable-conduit driving device is compensated, the average errors in the [Formula: see text], [Formula: see text], and [Formula: see text] directions of the needle tip entering the tissue are less than 2[Formula: see text]mm. The consequence verifies that it can meet the requirements for breast biopsy robot application under MR environment.
