Design and Implementation of PWM Signal in Servo Control

The PWM signal can be generated by many ways. However, the qualities of the PWM generated are very different from each other. In order to evaluate different methods concretely, four appraisal principles on the rationality of the PWM signal generation methods were put forward. Then, the theory of time-sharing batch processing was proposed, by which a PWM signal generation method for the servo control based on the SCM of C8051F040 was implemented. Finally, the rationality of this method was evaluated by the four appraisal principles. The correctness of the evaluating result was testified in practice.

Research on Programming for the Motion of Humanoid Robot

In order to meet the storage space requirements for the humanoid robot’s moving data, a structure array was used to store the data of each servomotor. In this method, the servomotors not rotating were ignored, so a lot of storage space was saved. The presetting data in the action groups were read sequentially and were changed to the rotating angles of the servomotors so as to complete the actions of the humanoid robot. If the repeated actions were designed, the corresponding moving data could be called again. This method has been successfully applied in robot dancing competitions.
