This thesis is dedicated to the automation of tests of the thermostats developed by the company Honeywell. The first chapter presents a problem of self-testing of thermostats, followed by a discussion of possible approaches to solutions. Attention is paid to testing the functionality of the HMI of thermostats, especially to the part of the system, that deals with activation of touchscteen, but no other part of the problem are omitted in the text. Discussions of the problematic passes into the design and implementation of specific design solutions. The selected design of 3D-router, which moves in three orthogonal coordinates and resembles to a coordinate drill for example. First, it describes the basic concepts of mechanic and electronic part of equipment, and subsequently is designed and implemented control electronics for mechanical activator HMI. Each of the electronics components are described in detail and values of parts are based on the calculation with the exception of finished parts. The proposal of the electronics follows the possibility of maximization of universality module for applications in similar applications. The functionality of the electronics is controlled by a microprocessor with a custom program that is described in the work. Source code of some the programs is not available because it is know-how of the company. Next part of the thesis deals with optimization of the moving of axes, optimization is done empirically by measuring. An important issue is compliance with the accuracy required position, also part of the work is devoted to the issue of calibration position. Finally is solved the continuity on the superior system. It is designed and implemented the upper layer of the communication protocol used in the company. Work is the solution of specific corporate award thesis. Although it is a very specific role of the works are generally applicable for other applications. In particular, the proposed electronic represents relatively universal controller for stepper motor control.
