Abstract

This article proposed a method for robust robot localization by reducing the cumulative position error in inertia based localization. Conditioned on the assumption that the robot activity yard exhibits a checkerboard pattern, a sensor arrangement as well as corresponding rule are designed to compensate the cumulative position error from inertia dead-reckon approach. Theoretically it can be verified that the error is within 3cm (depending on the line width on the ground).
