The paper illustrates a system for man‐machine interaction in quasi‐natural language. The scope of the interaction is in the description of the sequence of tasks to be executed by an industrial robot for the assembly of mechanical systems.

The purpose of this paper is to discuss some considerations about the problem of Natural Language Understanding with respect to the particular semantic domain of Robotics. The goal that makes realistic this research direction is the programming of a robot in Natural Language. A system called DONAU (Domain Oriented NAtural Language Understanding system) written in LISP and in MICROPLANNER has been developed on the UNIVAC 1108 computer of the MP‐AI Project, and experimental results have been obtained. This system represents an advanced contribution in the domain of Robotics and it is also a base for developing a more general Natural Language Understanding System.

The automation of complex handling and assembly operations can be achieved by the introduction of industrial robots, computer‐controlled and equipped with simple tactic sensors. A difficult problem in such robots are emergency situations when a defective component part is encountered. The lack of the capability for an automatic emergency recovery is a serious limitation of the present industrial robots. The purpose of this paper is to investigate and illustrate these emergency situations and the problem of emergency recovery, and to propose a solution by suitable software. It is also pointed out that some features of Artificial Intelligence programming languages are suitable for solving this problem in an industrial robot. The problem of suitable software for such robots is then approached on the basis of the obtained results implemented on a UNIVAC 1108 computer, by simulating the behaviour of a SIGMA robot.

This paper is devoted to a manipulation theory for industrial robots. The proposed knowledge representation model is based on a simple algebraic formalism and is shown to be adequate and suitable for actual applications in the field of assembly robots and manipulators. A FORTRAN system is illustrated which supports the proposed model and is implemented on a LABEN 70 minicomputer used for on‐line control of the SUPERSIGMA multipurpose assembly robot developed at the Milan Polytechnic Artificial Intelligence Project. The experimental work done is reported.

The role of microcomputers and their applications in industrial robotics is illustrated. The special case of an intelligent robot is examined in detail. The design of a microcomputer to be used for automatic spatial ordering of objects is presented, and the experimental results are briefly exposed and critically evaluated.
