Autonomous orbit maintenance system
Acta Astronautica, 1996Abstract Orbit maintenance is a major cost factor for Earth satellites in specialized orbits, such as a repeating ground track, or in formations. While autonomous attitude control is well established, the spacecraft's orbit is usually uncontrolled or maintained by ground station commands.

Cooperative construction and maintenance of maps for autonomous navigation
Robotics and Autonomous Systems, 1997Abstract In this paper, an uncertain representation of an indoor environment is used to provide the robot with an a priori map. The major originality of such a representation comes from its human origin. In our specific disabled-oriented application, the on-board person is used as an “intelligent sensor” which provides the system with some pertinent ...

Evolution of Autonomous Hierarchy Formation and Maintenance
Artificial Life 14: Proceedings of the Fourteenth International Conference on the Synthesis and Simulation of Living Systems, 2014Hierarchy among social animals is ubiquitous, and affects the social structures of gregarious species not only by interaction among species within the population, but also through other social forces such as mating, nesting location, amount and the quality of food they receive, or reproductive success. Since T. Schjelderup-Ebbe developed the structural

Analysis of investments in autonomous maintenance activities
IIE Transactions, 2000In this paper, we model the situation where operator maintenance activities improve the failure process of equipment. We analyze the business decision to reduce both the mean and variance of the production cycle time and the overall inventory level through an investment in planned autonomous maintenance.

Autonomous Maintenance for Through-Life Engineering
2014This chapter looks at the overall theme of automating maintenance practices with a particular focus upon the application of robotics within this field. Covering the current state of the art in automating maintenance processes this chapter also looks at the current challenges to moving beyond simple inspection and diagnosis to the design and ...

Persistence Acquisition and Maintenance for Autonomous Formations
2005 International Conference on Intelligent Sensors, Sensor Networks and Information Processing, 2005Built upon a recently developed theoretical framework, we consider some practical issues raised in autonomous multi-agent formation control. We use the notions of rigidity and persistence to analyze the cohesiveness of the formation structure and maintenance of the constraints on each individual agent.

An integrated approach to autonomous maintenance management
Integrated Manufacturing Systems, 1999This paper describes work undertaken to support an integrated approach to the autonomous maintenance management of machine tools and flexible manufacturing systems. The work described was initiated as part of a collaborative research project, funded under the European Community Eureka Maine project initiative as EU744: Integrated Condition and ...
