The idea of the project is to trace the robot position and orientation and precise it by the implementation of the advanced algorithms based on triangulation and trilateration methods. Precise navigation is a difficult task since the odometry sensors used in this context are subject to systematic and random errors. The former ones result from inaccuracies in the mechanical construction of the vehicles, e.g. the wheel diameters can be unequal or the nominal direction of the wheels is different from real.
