Desarrollo de prototipo LiDAR para pequeños robots móviles

Abstract

LiDAR (Light Detection and Ranging), in a rapidly growing technology that offers solutions to distance measurement, object detection, and mapping problems with high precision using sensors, has allowed it to have a considerable and constantly growing field of application derived from continuous research into its qualities, modifications, and combinations with various other technologies. Currently, LiDAR is capable of obtaining three-dimensional geospatial data of objects at high speed. The use of strategically positioned sensors has led to a change in the way the world is digitized. However, this incredible tool has a disadvantage: its cost, which is quite high. At the moment, the use of LiDAR technology is restricted to large corporations or government entities. Alternatives to solve the raised difficulty have led to the use of a variety of sensors that emulate the features provided by a LiDAR sensor; therefore, this article details the process of replacing the LiDAR sensor with a Time-of-Flight (TOF) infrared sensor which retains the operating principle of a LiDAR sensor, adapted to a small autonomous mobile robot that calculates distances to objects, records its surroundings, transmits data via wifi to a platform on thinkspeak for real-time reading, and has manual and automatic scanning mode operation of the place.
