Bulldozer: um robô que reconhece o seu passado

Abstract

This article describes the Bulldozer IV robot, winner of the Micro-Rato 2001 contest. It is an evolution of previous versions to which a new micro-controller, an electronic compass and an optical computer mouse were added. All the hardware and software of the previous versions of Bulldozer are reused, with just minor changes. In this paper some important hardware and software issues are discussed, particularly global positioning in the maze and returning to initial position with out any previous information.
