The serial mechanism type synthesis algorithms and the computer automation imple- mentation were studied based on POC set. Firstly, the algorithm for serial mechanism type synthesis was established, and a new expression method for the dimensions and directions of the serial mecha- nism end-reactor's translations and rotations was proposed. This paper specifically described the processes on algorithm and automation implementation of n-DOF serial mechanism which were based on C language. Secondly, the program interface was completed by MATLAB which optimized the hu- man-computer interactions. Finally, using the 4-DOF serial mechanism type synthesis as an example, the program may automatically generate 10 kinds of 1T3R serial mechanisms, 23 kinds of 2T2R serial mechanisms and 85 kinds of 3T1R serial mechanisms. The users only needed to input the POC set of the mechanisms which they wanted to create, and then the program may automatically generate the results, this operation has good usability and universality.
