To facilitate the learning of automatic navigation systems by engineering students an easy to obtain platform is useful. The topic of this thesis is the design and implementation of a basic self-guided vehicle that can be programmed and expanded by anyone possessing basic experience with the C programming language. The Self-Guided Micro Vehicle, (SGMV), uses off-the-shelf easy to obtain parts such as a toy R/C truck and the Handyboard to maximize availability of this technology to students.This thesis divides the SGMV design process by functionality. It starts by documenting the locomotion system, which was a modified R/C toy truck. Next, it describes the Microcontroller board and the Handyboard. Then it highlights the programming language, Interactive C, which makes multitasking systems easy for beginners. The sensor system was comprised of a GPS receiver, a solid state electronic compass and a wireless communications system.

This master’s thesis describes possibilities of usage of ZigBee communication protocol and integrated circuit ELM 327 in problem of realization universal diagnostic device, running by OBDII communication standards, which can be used to monitor function of all car´s electronic systems. Thesis also deals with design and realization of necessary electro technical devices and modules followed by compilation of control software and experimental measurements of these devices in real traffic flow. In the first part of project, there are reminded some basic features and parameters of OBDII, followed by description of ways how to use OBDII and adumbrating how to realize universal diagnostic system. The analysis of ZigBee system focused on XBee circuits follows. Construction, ways of data transfer and possibilities of controlling are described. Integrated circuits produced by ELM Electronics Company are introduced and possibilities of usage ELM 327 are described as requested by main task. Second part talks about designing of electronic circuits of this system, assembling schematic diagram and designing sources for production of PCB. Physical realization of these circuits and its first start is also included. Thesis finishes by dealing with practical experiences and measurements using real vehicles. This part talks also about means to improve system by several software solutions to reach more effective functioning of created device.
