In particular this work concentrates on three aspects: 1) how the qualitative reasoning techniques are combined with conventional numerical sensor fusion techniques is investigated and a method of developing a combined semi-quantitative model is introduced; 2) how the semi-quantitative information is analysed to perform the system monitoring and fault detection is discussed; and 3) the implementation of the diagnosis using fault model free methodology is introduced. A constraint violation based approach is described. The application of the algorithms developed is demonstrated through a number of examples, based on real data.<<ETX>>","PeriodicalId":133630,"journal":{"name":"Proceedings of 1994 IEEE International Conference on MFI '94.

The function is broken down into multiple agents, each of which samples a subset of a large sensor input space. Additional fuzzy agents are employed to fuse the recommendations of the local agents. Real-time implementation without special hardware is possible by using singleton output values during fuzzy rule evaluation. A linguistic syntax for fuzzy systems development is presented, allowing complex nonlinear control functions to be defined using qualitative expressions rather than mathematical terms. Our development tool, PCFUZ, translates this syntax off-line into a data structure for fast execution at run time. Using this system, a fuzzy behavior-based reactive control system has been implemented on an autonomous mobile robot, MARGE, with great success.<<ETX>>","PeriodicalId":133630,"journal":{"name":"Proceedings of 1994 IEEE International Conference on MFI '94.

This technique is useful in tasks such as localizing an object in a robot hand. It is assumed that visual data are provided by a monocular visual sensor, while tactile data by a planar-array tactile sensor in contact with the object. Visual data are used to generate a set of hypotheses about the 3D object's pose, while tactile data to assist in verifying the visually-generated pose hypotheses. We specifically focus on using tactile data in hypothesis verification. A set of indexed bounds on the object's six transformation parameters are constructed from the tactile data. These indexed bounds are constructed off-line by expressing them with respect to a tactile-array frame. At run-time, each visually-generated hypothesis is efficiently compared with the touch-based bounds to determine whether to eliminate the hypothesis, or to consider it for further verification. The proposed technique is tested using simulated and real data.<<ETX>>","PeriodicalId":133630,"journal":{"name":"Proceedings of 1994 IEEE International Conference on MFI '94.

In these environments inferences are rarely certain due to: unreliable data, inappropriate inference rules, and indeterminate temporal nature of data. Thus, there is a vital need for an effective certainty management scheme for these real-world applications. This paper presents extensions to our earlier paper (1989) and presents a formalism for computing membership functions as a mechanism for combining evidence. It proposes a \"unified\" methodology that combines certainties associated with evidence and rules for a given proposition, and systematically propagates these certainties down the (rule-based) decision tree. The methodology takes into account the relative importance of the propositions as well as the rules. The proposed methodology supports both numeric certainty values and linguistic variables that model human cognition. In addition, the methodology supports \"confirmation\" and \"disconfirmation\" constructs that are very useful for knowledge engineering.<<ETX>>","PeriodicalId":133630,"journal":{"name":"Proceedings of 1994 IEEE International Conference on MFI '94.

The main advantages of this approach include the simplicity of the representation of free space and the guidance for obstacle avoidance available trough the variation in the potential field. Newtonian potential function can be used to represent polygonal objects and obstacles wherein their boundaries are assumed to be uniformly charged. In this paper, the idea is extended to more general cases where the source distributions can also be linear or quadratic. It is shown that the potential function for these distributions can also be derived in closed form. Possible applications of these analytic results include the modeling of free space of complex shape, and the representation for objects and obstacles having properties of interest which are not homogeneous along their boundaries.<<ETX>>","PeriodicalId":133630,"journal":{"name":"Proceedings of 1994 IEEE International Conference on MFI '94.

This paper copes with the recognition of non-polyhedral objects, described each one by a REV graph and an aspect table, required to afford reasoning about visibility. The authors focus on the relations between segmentation and recognition strategies. A set of segmentation operators, executed by logical sensors, can be requested with respect to the state of the recognition task, in order to extract the more suitable set of features from the sensory data; if needed, the fusion of perceptual data can provide the more accurate estimates of the perceived geometric features. The control module of the recognition task, follows a classical \"hypothesize and test\" paradigm; this paper concerns only the hypothesis generation and verification, after one acquisition. Recognition strategies could be compiled off line, according to the object and the sensor models. The authors show how such strategies allow one to limit complexity of the segmentation and recognition processes; experimental results on real perceptual data, validate this method.<<ETX>>","PeriodicalId":133630,"journal":{"name":"Proceedings of 1994 IEEE International Conference on MFI '94.

This paper describes a PC-based feature selection system that solves this problem. The system uses a real-time fuzzy neural network. By using the numerical data about the membership functions and by testing thousands of feature subset combinations, the system searches for a subset that increases the separation between classes. If such a subset exists, its use makes it easier to identify the classes. The use of fewer features also results in smaller array sizes and a faster operation. The results of applying this technique to two different systems are discussed.<<ETX>>","PeriodicalId":133630,"journal":{"name":"Proceedings of 1994 IEEE International Conference on MFI '94.

This problem is very important when in the practice many parts of the system state are inaccessible. An observer capable of estimating the state of nonlinear systems with unknown inputs can also be of tremendous use when dealing with the problem of fault detection measurement instruments, since in such systems most actuator failures can be generally modeled as unknown inputs (control) to the system. The necessary condition for observer existence is the system observability. We relate observability of states to the concept of sensors choice with respect to the control. An aspect of the concept such as observer is discussed, (known as the rank condition) observability condition is derived, and we present some simulation for wall-following in the paper.<<ETX>>","PeriodicalId":133630,"journal":{"name":"Proceedings of 1994 IEEE International Conference on MFI '94.
