Position estimation and motion control of omni-directional mobile robot with active caster wheels

Abstract

The Authors havebeendeveloping a omni-directional mobile robot with three active caster wheels. Position estimation with sensory systems of a mobile robot is fundamental function for autonomous navigation. The position tracking with odometry and position-based control algorithm for our omni-directional mobile robot are reported in this paper. Control architecture for this omni-directional mobile robot is also designed. The effectiveness of the proposed position estimation and motion control method was verified through experiments.
