Abstract: The present disclosure provides a linearity detecting method and apparatus for a servo position sensor, and a robot with the same. The method includes: collecting and saving an output angle of the servo under test; analyzing the output angle to obtain a relationship curve of angle and time of the servo under test to rotate for one turn; extracting angle information of a starting point to an ending point of the output angle corresponding to the position sensor in the servo under test based on the relationship curve of angle and time to obtain valid angle data; and determining whether the output angle corresponding to the position sensor is linear based on the valid angle data. The present disclosure can solve the problem that an external sensor and a fixture are required when detecting the linearity of the sensor which causes complicated operation, high detection cost, and low detection efficiency.

Abstract: A computer-implemented method for setting device identification includes: a main control circuit sending a first identification to a first device coupled to the main control circuit to set the first identification on the first device. The main control circuit sends a second identification to a second device coupled to the main control circuit to set the second identification on the second device. The first identification is different from the second identification when the kind of the first device is the same as that of the second device, and the first identification is the same as or different from the second identification when the kind of the first device is different from that of the second device. A main control circuit and a robot for performing the setting method are also provided.
