In the world of mobile robot navigation, the ultrasonic sensors stand out for presenting attractive features at
an affordable cost. The main problem in the use of these devices lies in the difficulty of correctly interpreting
the obtained data, which means that their efficiency is limited. This paper focuses on the improvement and
implementation of a low cost location system based on ultrasonic sensors. Through the combination of mathematical techniques and signal processing it is possible to make the system more accurate and reliable. The
developed system includes the data acquisition, the signal filtering, and the trigonometric methods to estimate
the coordinates of a target and can be assembled in a mobile robot
