This algorithm enhances force control accuracy and compliance by adaptively adjusting damping and stiffness coefficients. Furthermore, a Breast Surface Adaptive Control Strategy (BrS\u2010ACS) is introduced. This strategy adjusts the alignment of the probe with the normal of the breast surface. Meanwhile, the influence of admittance parameters on compliance is experimentally analysed, with an error band used for evaluation.<\/jats:p>\n                  <\/jats:sec>\n
