Wave propagation in linear elastic solids of unknown space-varying physical characteristics is considered in this paper. We propose a two step procedure in which one first builds a linear parametric model of the system using suitable PDEs approximation and discretization tools, and then uses standard parametric identification techniques which compute the parameter estimates.
In this paper we study the problem of generating control programs, i.e. strings of symbolic descriptions of control-interrupt pairs (or modes) from input-output data. In particular, we take the point of view that such...

In this paper we study the problem of generating control programs, i.e. strings of symbolic descriptions of control-interrupt pairs (or modes) from input-output data. In particular, we take the point of view that such control programs have an information theoretic content and thus that they can be more or less effectively coded. As a result, we focus our attention on the problem of producing low-complexity programs by recovering the strings that contain the smallest number of distinct modes. An example is provided where the data is obtained by tracking ten roaming ants in a tank.

Autonomous long-range navigation in partially known planetary-like terrains is still an open challenge,for robotics. Navigating hundreds of meters without any human intervention requires the robot to be able to build various representations of its environment, to plan and execute trajectories according to the kind of terrain traversed. to control its motions and to localize itself as it moves. All these activities have to be scheduled, triggered, controlled and interrupted according to the rover context. In this paper we briefly review soniefunctionalities that have been developed in our laboratory and implemented on board the Marsokhod model robot, Lama. We then present how the various concurrent instances of the perception, localization and motion generation functionalities are integrated. Experimental results illustrate the functionalities throughout the paper.

Newly emerging robotics applications,for domestic or entertainment purposes are slowly introducing autonomous robots into society at large. A critical capability of such robots is their ability to interact with humans, and in particular, untrained users. In this paper we explore the hypothesis that people will intuitively interact with robots in a natural social manner provided the robot can perceive, interpret, and appropriately respond with familiar human social cues. Two experiments are presented where naive human subjects interact with an anthropomorphic robot. We present evidence for mutual regulation and entrainment of the interaction, and we discuss how this benefits the interaction as a whole.
