Previous issue date: 2015-03-11 / Programming multi-robot autonomous systems can be extremely complex without appropriate software development techniques to abstract hardware faults, as well as can be hard to deal with the complexity of software required the coordinated autonomous behavior. Real environments are dynamic and unexpected events may occur, leading a robot to unforeseen situations or even fault situations. This work presents a method of integration of Jason multi-agent system into ROS robotic framework. Through this integration, can be easier to describe complex missions by using Jason agent language and its resources, as well as abstracting hardware details from the decision-taken process. Moreover, software modules related to the hardware control and modules which have a high CPU cost are separated from the planning and decision-taken process in software layers, allowing plan and software modules reuse in different missions and robots. Through this integration, Jason resources such as plans reconsideration and contingency plans can be used in a way where they can enable the robot to reconsider its actions and strategies in order to reach its goals or to take actions to deal with unforeseen situations due the environment unpredictability or even some robot hardware fault. The presented integration method also allows the cooperation between multiple robots through a standardized language of communication between agents. The proposed method is validated by a case study applied in real robots where a robot can detect a fault in its hardware and diagnose it through the help of another robot, in a highly abstract method of cooperative diagnosis. / A programa??o de sistemas aut?nomos multi-rob? pode ser extremamente complexa sem o uso de t?cnicas de desenvolvimento de software apropriadas ? abstra??o de caracter?sticas de hardware, assim como pode ser dif?cil lidar com a complexidade de software necess?ria ao comportamento aut?nomo coordenado. Ambientes reais s?o din?micos e eventos inesperados podem ocorrer, levando um rob? a situa??es n?o previstas ou at? mesmo situa??es de falha. Este trabalho apresenta um m?todo de integra??o do sistema multi-agente Jason com o framework rob?tico ROS. Atrav?s desta integra??o, miss?es complexas podem ser mais facilmete descritas tendo em vista o uso da linguagem de agentes e seus recursos, bem como a abstra??o de detalhes de hardware do processo de tomada de decis?o. Al?m disso, m?dulos de software vinculados ao controle do hardware e m?dulos com alto consumo de recurso de CPU s?o separados das rotinas de planejamento e tomada de decis?o atrav?s de camadas de software, possibilitando o reuso de planos e m?dulos de software em diferentes miss?es e rob?s. Atrav?s desta integra??o, recursos do sistema multi-agente, tais como a reconsidera??o de planos e planos de conting?ncia, podem ser utilizados de forma a permitir que o rob? reavalie suas a??es e estrat?gias a fim de atingir seus objetivos ou tome a??es de forma a lidar com situa??es imprevistas diante da dinamicidade do ambiente ou quando falhas s?o detectadas no hardware do rob?. A integra??o permite ainda a coopera??o entre m?ltiplos rob?s atrav?s de uma linguagem de comunica??o padronizada entre agentes. O m?todo proposto ? validado atrav?s de um estudo de caso aplicado a rob?s reais onde um rob? pode detectar falhas em seu hardware e diagnostic?-las atrav?s da ajuda de outro rob?, em um m?todo cooperativo de diagn?stico altamente abstrato.
