An approach to extend process automation systems with cooperating subprocess agents is presented in this paper. According to this approach a society of subprocess agents supervises an ordinary process automation system. The functionality of this agent layer includes supervising the lower-level automation system, semi-autonomous reconfiguration of its… (More)
Application of agent technology to design and implementation of process automation systems has been proposed by some researchers. The purpose of this paper is to review current knowledge of this issue. The starting point of the study is the functional requirements of a process automation system. The requirements are compared with the models of agent… (More)
In this paper the development of an unmanned ground vehicle for task-oriented military applications is described. The instrumentation of the vehicle platform and observations from the teleoperation tests are presented, while the specific scope is in the analysis of the communication delay associated to the teleoperation. Safety aspects are addressed as well.
This paper studies issues concerning the application of cooperative information agents to information handling in automation systems. The suggested approach utilizes agent-based layer as an extension to ordinary automation system, thus offering new functions without the need of replacing the existing automation system. The proposed architecture uses… (More)
Societies are formed as collaborative structures to execute tasks which are not possible or are difficult for individuals alone. There are many types of biological societies formed by animals, but societies formed by machines or robots are still rare. This paper introduces the concept of an application oriented robot society formed by autonomous underwater… (More)
Cooperation as a mean to adapt to dynamic environments is well known in animal world from the social insects up to primates. But similar behavior seems to exist also in simple unicellular microbes. In this paper a novel approach for a very application oriented multi-agent system is taken. The principles of this robot society are derived from bacteria, which… (More)
—An approach to modeling cooperative control systems and their operation in process automation is presented in this paper. In this approach agent-oriented software engineering techniques are used thoughout the design of cooperative control systems both as modeling method and as implementation technology. A part of a process automation system is modeled as a… (More)
