Global action selection for illumination invariant color modeling

Abstract

A major challenge in the path of widespread use of mobile robots is the ability to function autonomously, learning useful features from the environment and using them to adapt to environmental changes. We propose an algorithm for mobile robots equipped with color cameras that allows for smooth operation under illumination changes. The robot uses image statistics and the environmental structure to autonomously detect and adapt to both major and minor illumination changes. Furthermore, the robot autonomously plans an action sequence that maximizes color learning opportunities while minimizing localization errors. Our approach is fully implemented and tested on the Sony AIBO robots.
