Surrogate-robot

The purpose of this project was to achieve long distance communication with mobile robots that act as a surrogate to the user, thus being a type of telepresence robots. The most accessible way of implementing this was in exploiting the cellular 2G-3G network. Research on implementation of servo motors with DTMF keys was conducted, potraying a necessity of enhancing the DTMF communication model. We created two different multiplexing models for variable length word transfer through DTMF. Time combination was more feasible and error free compromising the speed of the system. Along with this a working prototype with various functions to make the idea of ubiquitous robots feasible was implemented thus calling it a surrogate for the user´s activities.
