A mobius automation: an application of artificial intelligence techniques

Abstract: A research project applying artificial intelligence techniques to the development of integrated robot systems Is described. The experimental facility consists of an SDS-940 computer and associated programs controlling a wheeled vehicle that carries a TV camera and other sensors. The primary emphasis is on the development of a system of programs for processing sensory data from the vehicle, for storing relevant information about the environment, and for planning the sequence of motor actions necessary to accomplish tasks in the environment. A typical task performed by our present system requires the robot vehicle to rearrange (by pushing) simple objects in its environment A novel feature of our approach is the use of a formal theorem-proving system to plan the execution of high-level functions as a sequence of other, perhaps lower-level, functions. The execution of these, in turn, requires additional planning at lower levels. The main theme of the research is the integration of the necessary planning systems, models of the world, and sensory processing systems into an efficient whole capable of performing a wide range of tasks in a real environment.

Talking with a robot in English

Abstract: This paper gives an overview of the present status and future plans of a research project aimed at communicating in natural language with an intelligent automaton. The automaton in question is a computer-controlled mobile robot capable of autonomously acquiring information about its environment and performing tasks normally requiring human supervision. By natural language communication is meant the ability of a human to successfully engage the robot in a dialog using simple English declarative, interrogative, and imperative sentences. Communication is accomplished by means of a natural language interpretive question-answering system (ENGROB) consisting of six distinct components: a syntax analyser, a semantic interpreter, a model of the robot's environment, a deductive, automatic theorem proving system, an English output generator, and a repertoire of basic robot capabilities for sensing and manipulating the environment. An example is given that illustrates the type of processing done by each component, and the nature of component interactions.

Robot control strategy

Abstract: A behavioral theory of information processing based on ethological observations has been tested experimentally by programming a robot control system. The resultant software has successfully simulated robot operation. Three basic types of software modules are assumed as elements. These accept input stimuli and generate detailedstrings of motor response "units" to attain design goals. A complex process of interaction between the modules permits the consideration of many alternative actions while focusing attention on a selected set of input signals. ' The organization is shown to have especially flexible characteristics adapted to robot control and permits a recursive definition of some of the modules. Brief comparisons with other robot systems in being indicate some of the relationships between the different design approaches so far proposed.
