Abstract: A mechanical arm and an operation system to perform a stir-frying action in cooking. The mechanical arm has motors and a plurality of links connecting with a pan. The links length and the binding angle are limited according to the pan action and the chefs' wrist through sum of sine function. In the other hands, weight and viscosity are different between different food materials. The operation system further controls the parameters, which include the velocity, the speed ratio of forward and backward, the rising time, the angel region of motor and the initial angle offset of pan, to adjust the action of mechanical arm performing the stir-flying action. It is suitable to decrease the time of food cooking and the hand burden. Therefore, the chefs can have more time to produce pre-treatment or post-production.
