In this paper, we consider optimal resolution of air traffic (AT) conflicts. Aircraft are assumed to cruise within a given altitude layer and are modeled as a kinematic system with constant velocity and curvature bounds. Aircraft cannot get closer to each other than a predefined safety distance. For such system of multiple aircraft, we consider the problem(More)
We are pleased to introduce this collection of papers covering different aspects of intelligent transportation systems. These papers were selected from a list of papers presented at the Intelligent Transportation Systems Conference and Intelligent Vehicles Symposium, jointly held in Detroit, MI, October 3–5, 2000. In order to bear witness and celebrate the(More)
In this paper, we propose a novel policy for steering multiple vehicles between assigned start and goal configurations, ensuring collision avoidance. The policy rests on the assumption that all agents are cooperating by implementing the same traffic rules. However, the policy is completely decentralized, as each agent decides its own motion by applying(More)
This paper presents a complete characterization of shortest paths to a goal position for a robot with unicycle kinematics and an on-board camera with limited field-of-view (FOV), which must keep a given feature in sight. Previous work on this subject has shown that the search for a shortest path can be limited to simple families of trajectories. In this(More)
In this paper we propose a new approach to motion planning, based on the introduction of a lattice structure in the workspace of the robot, leading to efficient computations of plans for rather complex vehicles, and allowing for the implementation of optimization procedures in a rather straightforward way. The basic idea is the purposeful restriction of the(More)
In this paper we address the problem of detecting faulty behaviors of cooperative mobile agents. A novel decentralized and scalable architecture that can be adopted to realize a monitor of the agents’ behavior is proposed. We consider agents which may perform different independent tasks, but cooperate to guarantee the entire system’s safety. Agents plan(More)
In this article, we consider how a very large numbers of robots, differing in their bodies, sensing, and intelligence, may be made to coexist, communicate, and compete fairly toward achieving their individual goals, i.e., to build a society of I robots. We discuss some characteristics that the rules defining acceptable social behaviors should possess. We(More)
In this paper we describe work being done at our Department to make the Robotics laboratory accessible to students and colleagues, to execute and watch real-time experiments at any time and from anywhere. We describe few different installations, and highlight the underlying philosophy, which is aimed at enlarging the lab in all the dimensions of space,(More)
