-The bending stiffness error $\epsilon_h$ due to the height estimation error $\delta h$ is shown in Figure ref:fig:test_joints_effect_height_error.
-The height estimation is foreseen to be reasonably accurate to within $\pm 0.4\,mm$ which should make the bending stiffness error $\epsilon_h < 3.5\,\%$.

 **** Estimation error due to force and displacement sensors accuracy
 The maximum error of the measured displacement due the encoder non-linearity is $40\,nm$.
