Sistema para aviso de aproximação entre veículo e ponto estático

Abstract

This work presents a service to infer the positioning of a vehicle in relation to static points using the Arduino robotic platform. The Arduino platform is an open-source, low-cost software and hardware solution that allows to investigate and evaluate new services before making them available in practice. The scenario in question can be found in many everyday situations in traffic. Examples include approaching a bus at stop points, and approaching vehicles at a set of traffic lights. The communication between the vehicle (Arduino robot) and the static points (simulated by conventional computers) is carried out via Wi-Fi network without the need for GPS tools. The po- sition of the static points is known and the vehicle moves following a pre-established route. The position of the vehicle relative to the static points is estimated solely by the use of signal strength of the Wi-Fi network.
