Abstract
The control of mobile robots acting autonomously in the real world is one of the long-term goals of the field of artificial intelligence. So far the field lacks methods bridging the gap between the sophisticated symbolic techniques to represent and reason about action and more and more reliable low-level robot control and navigation systems. In this paper we present GOLEX, an execution and monitoring system for the logic-based action language GOLOG and the complex and distributed RHINO control software which operates on RWI B21 and B14 mobile robots. GOLEX provides the following features: it maps abstract primitive actions into low-level commands of the robot control system, thus allowing the user to concentrate on the application rather than the inner workings of the robot; it monitors the execution of the primitive GOLOG actions, making it possible to detect simple execution failures and timeouts; and it includes means to deal with sensing and user input and to continue the operation appropriately. We present two different real-world applications in which GOLEX successfully operated a mobile robot in dynamic and even unstructured environments. These results suggest that the time is ripe for using symbolic action languages for mobile robot applications.
