Abstract
A method for estimating a roughness R of a surface is provided, including: measuring, during relative movement of at least one force sensor in a direction roughly parallel to the surface, at least one force Fperceived by the at least one force sensor in a direction which is roughly orthogonal to said direction of movement, and parallel to said surface; calculating at least one statistical parameter P representative of variations of the value of the measured at least one force F; and estimating the roughness R by calculating R=f(P), where f(P) is a function of the at least one statistical parameter P having at least some coefficients with values that are dependent on characteristics of the at least one force sensor used, and on a force with which the at least one force sensor is applied on said surface during the relative movement.
