Indoor localization for mobile robots using fiducial markers

Abstract

The work aimed to use fiducial markers to locate a robot indoors using a simulation environment as a testing tool. An environment with scattered fiducial markers was developed for the robot to identify and be able to recalculate its position with the odometer sensors reference frame. It was observed that this method applied for indoor environments has a low computational cost, caused for the readability of the landmarks, and a high accuracy in robot localization compared to other methods.
