The Rendezvous Problem with Discontinuous Control Policies
No full textIn this technical note we consider the multi-agent rendezvous problem and we state new sufficient conditions for characterizing the control policies that assure rendezvous. Our condition are less restrictive than those presented until now in the literature, since, in particular, continuity is substituted by a milder requirement concerning the behavior of the control laws around points of discontinuity. In addition, our results apply to groups of agents moving in Rn, for any finite n
Robotic tools and systems for man/machine cooperation in underwater archaeology
No full textThe paper describes the architecture and the features of an advanced, robotic platform for underwater exploration and intervention. The characteristics of the robotic platform make it suitable for use in the field of underwater archaeology, where cooperation between man and machine can represent a winning solution to overcome the difficulties of operating in harsh but fragile environments. The use of automatic techniques for navigation, guidance and control of marine vehicles, for managing communication under and over the sea surface, for processing and interpreting large amounts of nonhomogeneous, asynchronous data is the key ingredient in the development of the robotic platform. Test and experiments in field missions represent the main validation method for the hardware and software solutions that implement such techniques. Reference is made to a number of recent papers and to the activity carried on in the framework of structured research projects
