CRAB: um robot caranguejo

Abstract

This paper presents a brief description of the CRAB robot developed by the team of the Unibersity of Aveiro that participated in a world mobile robotics competition in the scope of the 7th International Festival of Science and Technology that took place in Vierzon, France, from the 23rd to the 28th of May 2000. The technical specifications of the competition require that the robots are able to follow a line 60m long, to go over ramps 20% steep and to gather billiard balls placed 80cm away from the line and on narrow and short poles. The CRAB robot meets all those specifications and has a distinctive feature of being controlled by a distributed system based on CAN with two low processing-power nodes.
