  This paper presents the development process starting from a simple electronic module for amplification of EMG signals. During development the tasks to be solved were extended towards the creation of an EMG-base controller that eventually can be connected to a PC. Among the main goals were the simplicity and low cost of production. There are similar devices commercially available, but the main focus was on the whole process of design, testing, fabrication and the exploration of application areas. It was important to use medical recommendations. The device matches the suggestion of SENIAM, except for the resolution of A/D conversion, which is permissible due to the fact that it was not designed for medical purposes. The final version is capable of detecting and amplifying EMG signals, with the appropriate filtering and digitizing procedures for further processing. With the development of wireless communication capabilities, the device which can be attached to the forearm can be used as a USB HID device with a PC. A number of additional applications are also discussed, pointing out the fact that this piece of technology offers a wide range of possibilities.

  A model vehicle has been developed further in order to perform automatic parking. Ultrasonic sensors and STM32 F4 Discovery microcontroller have been mounted. The driving assistant system can find the parking place then parallel parking is performed. The backward motion of the vehicle is carried out along two circular paths, which is followed by corrections of the position and orientation.

  A dolgozat címében is megjelenő témát járjuk körül. A projekt, ahogy a cím is említi, egy költséghatékony, internet – alapú mobilrobot tervezése és elkészítése, mellyel könnyen valósíthatók meg a különböző mobil robotikai feladatok. Ezt tettük elsősorban oktatási célokra és későbbi továbbfejlesztés esetén akár etorobotikai kutatások elősegítésére. A tervezés során fontos volt a lehető legnagyobb mértékű univerzalitás, egyszerűség és az alacsony anyagi keret. Jelen dolgozat ezen projekt koncepciójának vázlata.
