Particle Filter Tutorial for Mobile Robots This tutorial is extracted from my Ph.D. thesis [1]. It is available also as a technical report (TR-CIM-04-02)[2]. It is placed online to help other researchers that are interested in implementing a particle filter for mobile robots. A shorter version of this text was presented in the International Conference on Robotics and Automation 2003 (ICRA-2003) [3]. [1] Ioannis Rekleitis.
