  • Adaptive Fault Detection and Tolerance for Robots 

    Visinsky, Monica L.; Cavallaro, Joseph R.; Walker, Ian D. (TSI Press, 1994-08-01)
    In existing robot fault detection schemes, sensed values of the joint status (position, velocity, etc.) are typically compared against expected or desired values, and if a given threshold is exceeded, a fault is inferred. ...
  • 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 ...
  • Expert System Framework for Fault Detection and Fault Tolerance in Robotics 

    Visinsky, Monica L.; Cavallaro, Joseph R.; Walker, Ian D. (ASME, 1992-11-01)
    Fault tolerance is of increasing importance for modern autonomous industrial robots. The ability to detect and tolerate failures will enable robots to effectively cope with internal failures and continue performing assigned ...
  • 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 Detection and Fault Tolerance Methods for Robotics 

    Visinsky, Monica L. (1991-12-20)
    Fault tolerance is increasingly important in modern autonomous or industrial robots. The ability to detect and tolerate failures allows robots to effectively cope with internal failures and continue performing designated ...
  • 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 ...
  • 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 ...
  • New Dynamic Model-Based Fault Detection Thresholds for Robot Manipulators 

    Visinsky, Monica L.; Walker, Ian D.; Cavallaro, Joseph R. (IEEE Computer Society Press, 1994-05-01)
    Autonomous robotic fault detection is becoming increasingly important as robots are used in more inaccessible and hazardous environments. Detection algorithms, however, are adversely effected by the model simplification, ...
  • 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 ...
  • 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 ...
