Abstract: According to the class I size synthesis theory based on the basic idea of releasing roller centers and cam axes，some basic theories and important conclusions were summarized to solve the optimal cam axes [O**1]which were the most eligible solution in the whole processes of obstacle avoidance perfectly.To propose a new algorithm aiming at solving the optimum solution of the mechanisms，an analytic criterion of rollers and cams for avoiding obstacles in the whole procedure and simplified search areas [Σ][2]and [Σ][0] were presented，and then brought forward an ergodic search method to solve the feasible areas of cam axes [O**1] and roller centers C through the whole processes of avoiding obstacle successfully.The dimensional synthesis of disk cam mechanisms for obstacle avoidance and compact floating roller pushrods were resolved.A mechanism synthesis example was displayed.

Key words: floating roller pushrod, class I dimensional synthesis, most eligible solution, obstacle avoidance success, solution area, compact size solution
