    In the design and implementation of the software structure used in the distributed execution of a robotics language, there arises the problem of the modelization of distributed applications in a real-time context. Robotics applications need rigorous validation of the control software, at both the logic level and the temporal level. For a developer, one expected goal is to find an appropriate model...

    We present an interactive fuzzy satisficing method for multiobjective structured linear programs. By considering the imprecise nature of human judgements, we assume that the decision maker (DM) may have a fuzzy goal for each of the objective functions. Having elicited the corresponding linear membership functions, if the DM specifies the reference membership levels for all the membership functions... View full abstract»

    A robot can learn to act by trial and error in the world. A robot continues to obtain information about the environment from its sensors and to choose a suitable action to take. Having executed an action, the robot receives a reinforcement signal from the world indicating how well the action performed in that situation. The evaluation is used to adjust the robot's action selection policy for the g... View full abstract»

    The minimal directed distance function has been shown to have greater freedom in hypothesizing trajectories to be relaxed into admissibility. The minimum directed Euclidean distance (MDED) between two objects is the shortest relative translated Euclidean distance that results in the objects being just in contact. The MDED is also defined for intersecting objects and it then returns a measure of pe... View full abstract»
