This paper shows a prototype development of an intelligent line follower mini-robot system, the objective is to recognize, understand and modify the actual performance of the movements of the robot during its pathway by way of getting information in real time from different magnetic sensors implemented in the system and based in a V2X digital compass, microcontroller and odometric measurements. The paper shows as well, the system characterization of the V2X sensor (digital compas) and the cost-benefit of the prototype implementation and performance. The programming techniques and easy operation is detailed too.
