  • A Dynamic Fault Tolerance Framework for Remote Robots 

    Visinsky, Monica L.; Cavallaro, Joseph R.; Walker, Ian D. (IEEE, 1995-08-01)
    Fault tolerance is increasingly important for robots, especially those in remote or hazardous environments. Robots need the ability to effectively detect and tolerate internal failures in order to continue performing their ...
  • Dynamic Senor-Based Fault Detection for Robots 

    Visinsky, Monica L.; Cavallaro, Joseph R.; Walker, Ian D. (SPIE - The International Society for Optical Engineering, 1993-09-01)
    Fault detection and fault tolerance are increasingly important for robots in space or hazardous environments due to the dangerous and often inaccessible nature of these environs. We have previously developed algorithms to ...
  • Expert System Framework for Fault Detection and Fault Tolerance in Robotics 

    Visinsky, Monica L.; Cavallaro, Joseph R.; Walker, Ian D. (Elsevier Science Ltd, 1994-01-01)
    Fault tolerance is of increasing importance for modern robots. The ability to detect and tolerate failures enables robots to effectively cope with internal failures and continue performing assigned tasks without the need ...
  • Fault Detection and Fault Tolerance in Robotics 

    Visinsky, Monica L.; Walker, Ian D.; Cavallaro, Joseph R. (1991-07-01)
    Robots are used in inaccessible or hazardous environments in order to alleviate some of the time, cost and risk involved in preparing men to endure these conditions. In order to perform their expected tasks, the robots ...
  • Fault Tolerant Algorithms and Architectures for Robotics 

    Hamilton, D. L.; Visinsky, Monica L.; Bennett, J. K.; Cavallaro, Joseph R.; Walker, Ian D. (IEEE, 1994-04-01)
    As robot tasks in space, nuclear, and medical environments become more widespread, the issues of reliability and safety for robots are becoming more critical. Attempts to address these issues have resulted in a a recent ...
  • Keeping the Analog Genie in the Bottle: A Case for Digital Robots 

    Walker, Ian D.; Cavallaro, Joseph R.; Leuschen, Martin L. (IEEE, 1999-05-01)
    In this paper, we consider the case for adopting a truly 'digital' type of robot, which would evolve between a discrete and finite set of states. We adopt the point of view that the advantages of traditional robotic evolution ...
  • Layered Dynamic Fault Detection and Tolerance for Robots 

    Visinsky, Monica L.; Walker, Ian D.; Cavallaro, Joseph R. (IEEE Computer Society Press, 1993-05-01)
    Fault tolerance is increasingly important for space and hazardous environment robotics. Robots need to quickly detect and tolerate internal failures in order to continue performing their tasks without the need for immediate ...
  • Protective Operating System Shell Environment for Robots 

    Cavallaro, Joseph R.; Walker, Ian D. (SPIE, 1995-10-01)
    This paper describes the synthesis of a protective operating system shell environment for robots. The approach is designed to protect the robot from the effects of errors in the lower level manipulator system and the higher ...
  • Robot Fault Detection and Fault Tolerance: A Survey 

    Visinsky, Monica L.; Cavallaro, Joseph R.; Walker, Ian D. (Elsevier Science Limited, 1994-01-01)
    Fault tolerance is increasingly important for robots, especially those in remote or hazardous environments. Robots need the ability to effectively detect and tolerate internal failures in order to continue performing their ...
  • Robot Reliability Using Fuzzy Fault Trees and Markov Models 

    Leuschen, Martin L.; Walker, Ian D.; Cavallaro, Joseph R. (SPIE, 1996-11-01)
    Robot reliability has become an increasingly important issue in the last few years, in part due to the increased application of robots in hazardous and unstructured environments. However, much of this work leads to complex ...
  • Robotic Fault Tolerance: Algorithms and Architectures 

    Visinsky, Monica L.; Cavallaro, Joseph R.; Walker, Ian D. (Prentice Hall, Englewood Cliffs, NJ, 1993-04-01)
    Fault tolerance is an essential factor in ensuring successful autonomous systems, especially for robots working in remote or hazardous environments. To avoid the cost and risk involved in sending humans into these environs ...
  • A Survey of NASA and Military Standards on Fault Tolerance and Reliability Applied to Robotics 

    Cavallaro, Joseph R.; Walker, Ian D. (NASA, 1994-03-01)
    There is currently increasing interest and activity in the area of reliability and fault tolerance for robotics. This paper discusses the application of Standards in robot reliability, and surveys the literature of relevant ...
