An Indoor Localization System for Mobile Robots Using an Active Infrared Positioning Sensor

Abstract

Infrared (IR) sensors have been widely used as a distance measuring sensors to estimate the position of an object since they have short response time and high accura- cy. Therefore, we introduce the indoor localization system using an active infrared sensor and passive landmarks. However, there were several types of deviations from the actual values. We analyzed these errors and corrected them to develop the improved localization system.  Index Terms—infrared sensor, artificial landmark, multi- robot, indoor localization, intelligent space
