This paper describes the use of soft computing based techniques toward the acquisition of adaptive behaviors to be used in mobile exploration by cooperating robots. Navigation within unknown environments and the obtaining of dynamic behavior require some method of unsupervised learning given the impossibility of programming strategies to followfor each individual case and for every possible situation the robot may face. In this investigation in particular, it is intended to expose some of the benefits of cooperative learning robots using novel biologically inspired heuristic methods. Experiments were conducted using a Khepera mobile robot simulator which uses a neural network to generate behaviors based on robot sensor measurements. The training of this network was carried out with a Genetic Algorithm, where each individual is a neural network whose fitness functionis the output of a function, proportional to the are acovered by the robot.
