This article describes the implementation of an obstacle detector system based on laser technology (laser pointer) and the associated electronics used for correct and adequate operation. This system is part of a mobile robot that is able to move itself autonomously around an environment where light-colored obstacles are located. The obstacle detector is mainly composed of two functional blocks: a transmitter and a receptor. The idea consists of receiving the reflected power of an emitted laser beam from an obstacle. Using this method, the associated electronics (receptor) are able to estimate the distance from the mobile robot to the obstacle, depending on the received power. The main goal of this work is the implementation and characterization of an obstacle detector system using laser technology to be embedded in an autonomous mobile robot
