An automatic robot control system and methods relating thereto are described. These systems include components such as a touch screen panel (“TSP”) robot controller for controlling a TSP robot, a camera robot controller for controlling a camera robot and an audio robot controller for controlling an audio robot. The TSP robot operates inside a TSP testing subsystem, the camera robot operates inside a camera testing subsystem, and the audio robot operates inside an audio testing subsystem. Inside the audio testing subsystem, an audio signals measurement system, using a bi-directional coupling, controls the operation of the audio robot controller. In this control scheme, a test application controller is designed to control the different types of subsystem robots. Methods relating to TSP, camera, and audio robots, and their controllers, taken individually or in combination, for automatic testing of device functionalities are also described.

Aspects of the subject disclosure may include, for example, determining a type of Subscriber Identity Module (SIM) within a communication device, and identifying a first testing file associated with a physical SIM type. Further embodiments can include converting the first testing file to a second testing file according to the type of SIM, and transmitting the second testing file utilizing Over-the-Air (OTA) communications to the communication device. Additional embodiments can include providing first instructions to the communication device, wherein the first instructions activate the second testing file on the communication device, and providing second instructions to the communication device, wherein the second instructions initiate testing of the communication device according to the second testing file. Other embodiments are disclosed.
