    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (436 KB)

    Some aspects of automatic deburring by a robot are considered. The strategy proposed is based on constrained motion control, in which both force and position of the robot are simultaneously controlled. However, in practice, a robot may be in free unconstrained motion before it comes in contact with the environment. In order to control the deburring operation without switching controllers for the u... View full abstract»

  • A logical model for decision-making

    Publication Year: 1989, Page(s):1142 - 1147 vol.3
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (500 KB)

    The general form of a decision-making model raises hypotheses about the dynamics of stimulus, conception, and response. One might suppose that the decision progress begins with the perception of some sort of stimulus. The amount of information available for decision-making is often incomplete and hence any logic that attempts to model decision-making must be nonmonotonic in nature. The existing lo...

    The authors consider the problem of filtering images corrupted by non-Gaussian noise using the Kalman filter. Specifically, they have used the reduced updated Kalman filter (RUKF) for the sake of computational savings. They modified the original RUKF to accommodate the non-Gaussian noise using an efficient scheme proposed by them previously (1989). It is shown that the modification is simple and t...
