Wireless Position Tracking of a DTMF based Mobile Robot using GSM and GPS

The advent of new technologies has revolutionized the era of embedded system design in a way that every user is surrounded by smart devices (robots) which makes their life easier and comfortable. It has also been predicted by the researchers that by 2020, there will be billions of embedded devices talking to each other as compared to human beings termed as Internet of things (IOT). This paper is generally appropriated with the development of autonomous mobile robot used for wireless position tracking using GPS and sending that precise information on to a device such as mobile or tablet using GSM. This robot is equipped with GPS (for detection of location), GSM (for wireless data transfer), DTMF (for controlling robot with mobile or tab), sonar sensor (for obstacle detection) and flash light (for night vision). This mobile robot has wide variety of applications in industries like defense, aerospace, agriculture, and security etc. The basic functionality of the proposed design is simulated on proteus 7.1 and the complete design is implemented around ARM7 controller with required necessary interfaces.
