Self-Localization and Waypoints following of Holonomic Three Wheeled Omni-Directional Mobile Robot

摘要

This paper primarily focuses on the ‘Localization and Control’ problem with the holonomic class of mobile robots. The paper discusses a computationally less intensive with high rate localization and navigation techniques for a three wheeled omni-directional mobile robot, using wheel encoders and kinematic relations. Insight to an elegant and pragmatic approach to navigate the robot from point A to point B in the defined workspace, enabling the robot to autonomously reach a target position and orientation defined by the user, is given. Implementation of the ‘Go to Pose’ algorithm is done for both single-waypoint and multi-waypoint navigation. The experimental results obtained reinforce the robustness of the algorithm that incorporates PID controller.
