In order to set up the synthesis model of a function generating mechanism, the influence of controllable factors and noise factors on the movement precision of the mechanism was analyzed. A mathematical model considering clearance and structural error for the robust mechanism was established and an example of the slider-crank mechanism was given. The results show that the performance of the mechanism is robustness although the clearance and structural error is random variables.
