Distributed control of robotic networks a mathematical approach to motion coordination algorithms by Francesco Bullo( )

15 editions published in 2009 in English and held by 1,228 WorldCat member libraries worldwide

This self-contained introduction to the distributed control of robotic networks offers a distinctive blend of computer science and control theory. The book presents a broad set of tools for understanding coordination algorithms, determining their correctness, and assessing their complexity; and it analyzes various cooperative strategies for tasks such as consensus, rendezvous, connectivity maintenance, deployment, and boundary estimation. The unifying theme is a formal model for robotic networks that explicitly incorporates their communication, sensing, control, and processing capabilities--a

Notes on Averaging Over Acyclic Digraphs and Discrete Coverage Control( )

1 edition published in 2006 in English and held by 1 WorldCat member library worldwide

In this paper, we show the relationship between two algorithms and optimization problems that are the subject of recent attention in the networking and control literature. First, we obtain some results on averaging algorithms over acyclic digraphs with fixed and controlled-switching topology. Second, we discuss continuous and discrete coverage control laws. Further, we show how discrete coverage control laws can be cast as averaging algorithms defined over an appropriate graph that we term the discrete Voronoi graph

On Discrete-Time Pursuit-Evasion Games with Sensing Limitations( )

1 edition published in 2008 in English and held by 1 WorldCat member library worldwide

We address discrete-time pursuit-evasion games in the plane where every player has identical sensing and motion ranges restricted to closed discs of given sensing and stepping radii. A single evader is initially located inside a bounded subset of the environment and does not move until detected. We propose a Sweep-Pursuit-Capture pursuer strategy to capture the evader and apply it to two variants of the game: the first involves a single pursuer and an evader in a bounded convex environment and the second involves multiple pursuers and an evader in a boundaryless environment. In the first game, we give a sufficient condition on the ratio of sensing to stepping radius of the players that guarantees capture. In the second, we determine the minimum probability of capture, which is a function of a novel pursuer formation and independent of the initial evader location. The Sweep and Pursuit phases reduce both games to previously-studied problems with unlimited range sensing, and capture is achieved using available strategies. We obtain novel upper bounds on the capture time and present simulation studies that address the performance of the strategies under sensing errors, different ratios of sensing to stepping radius, greater evader speed and different number of pursuers

On Optimal Sensor Placement and Motion Coordination for Target Tracking( )

1 edition published in 2004 in English and held by 1 WorldCat member library worldwide

This work studies optimal sensor placement and motion coordination strategies for mobile sensor networks. For a target tracking application with range sensors, we investigate the determinant of the Cramer-Rao Lower Bound and compute it in the 2D and 3D cases. We characterize the global minima of the 2D case. We propose and characterize motion coordination algorithms that steer the mobile sensor network to an optimal deployment and that are amenable to a decentralized implementation. Finally, our numerical simulations illustrate how the proposed motion coordination algorithms lead to the improved performance of an extended Kalman filter in a target tracking scenario
Monitoring Environmental Boundaries with a Robotic Sensor Network( )

1 edition published in 2006 in English and held by 1 WorldCat member library worldwide

In this paper, we propose and analyze two algorithms to monitor an environmental boundary with mobile sensors. The objective is to optimally approximate the boundary with a polygon. In the first scenario the mobile sensors know the boundary and the approximating polygon is defined by the sensors' positions. In the second scenario the mobile sensors rely only on sensed local information to position some interpolation points and define an approximating polygon. For both scenarios we design algorithms that distribute the vertices of the approximating polygon uniformly along the boundary. The notion of uniform placement relies on a metric inspired by known results on approximation of convex bodies. The first algorithm is proved to converge in the case of static boundaries whereas the second one is provably convergent also for slowly-moving boundaries because of certain input-to-state stability properties
On Vehicle Placement to Intercept Moving Targets (Preprint)( Book )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

We address optimal placement of vehicles with simple motion, to intercept a mobile target that arrives stochastically on a line segment. The optimality of vehicle placement is measured through a cost function associated with intercepting the target. With a single vehicle, we assume that the target either moves with fixed speed and in a fixed direction or moves to maximize the vertical height or intercept time. We show that each of the corresponding cost functions is convex, has smooth gradient and has a unique minimizing location, and so the optimal vehicle placement is obtained by any standard gradient-based optimization technique. With multiple vehicles, we assume that the target moves with fixed speed and in fixed direction. We present a discrete time partitioning and gradient-based algorithm, and characterize conditions under which the algorithm asymptotically leads the vehicles to a set of critical configurations of the cost function
Nonlinear control of mechanical systems : a Riemannian geometry approach by Francesco Bullo( )

1 edition published in 1999 in Undetermined and held by 1 WorldCat member library worldwide

Nonlinear control of mechanical systems is a challenging discipline that lies at the intersection between control theory and geometric mechanics. This thesis sheds new light on this interplay while investigating motion control problems for Lagrangian systems. Both stability and motion planning aspects are treated within a unified framework that accounts for a large class of devices such as robotic manipulators, autonomous vehicles and locomotion systems. One distinguishing feature of mechanical systems is the number of control forces. For systems with as many input forces as degrees of freedom, many control problems are tractable. One contribution of this thesis is a set of trajectory tracking controllers designed via the notions of configuration and velocity error. The proposed approach includes as special cases a variety of results on joint and workspace control of manipulators as well as on attitude and position control of vehicles. Whenever fewer input forces are available than degrees of freedom, various control questions arise. The main contribution of this thesis is the design of motion algorithms for vehicles, i.e., rigid bodies moving in Euclidean space. First, an algebraic controllability analysis characterizes the set of reachable configurations and velocities for a system starting at rest. Then, provided a certain controllability condition is satisfied, various motion algorithms are proposed to perform tasks such as short range reconfiguration and hovering. Finally, stabilization techniques for underactuated systems are investigated. The emphasis is on relative equilibria, i.e., steady motions for systems that have a conserved momentum. Local exponential stabilization is achieved via an appropriate splitting of the control authority
Trajectories for Locomotion Systems: A Geometric and Computational Approach via Series Expansions( )

1 edition published in 2004 in English and held by 1 WorldCat member library worldwide

The objective of this research has been the design and validation of innovative methods for motion planning of highly mobile all-terrain vehicles and motion coordination for multi-vehicle networks. The initial focus of this research was on algorithms for (single) vehicle trajectory generation. We have studies fast local trajectory optimization algorithms for vehicles with limited control authority. The main research focus has been on a novel class of asynchronous distributed coordination algorithms for multi-vehicle networks. We have developed coverage and coordination algorithms for communication-constrained vehicle models. The algorithms are spatially distributed in the sense that only spatially localized information is required for their implementation. We believe this is a fundamental improvement over the current state-of-the-art in motion coordination. Finally, we have developed an outdoor experimental platform, called the Multi-Rover Network Laboratory," consisting of eight model rovers equipped with embedded computers, wifeless interfaces, and sensors

Adaptive and Distributed Algorithms for Vehicle Routing in a Stochastic and Dynamic Environment( Book )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

In this paper we present adaptive and distributed algorithms for motion coordination of a group of m vehicles. The vehicles must service demands whose time of arrival, spatial location and service requirement are stochastic; the objective is to minimize the average time demands spend in the system. The general problem is known as the m-vehicle Dynamic Traveling Repairman Problem (m-DTRP). The best previously known control algorithms rely on centralized task assignment and are not robust against changes in the environment. In this paper, we first devise new control policies for the 1-DTRP that: (i) are provably optimal both in light-load conditions (i.e., when the arrival rate for the demands is small) and in heavy-load conditions (i.e., when the arrival rate for the demands is large), and (ii) are adaptive, in particular, they are robust against changes in load conditions. Then, we show that specific partitioning policies whereby the environment is partitioned among the vehicles and each vehicle follows a certain set of rules within its own region, are optimal in heavy-load conditions. Building upon the previous results, we finally design control policies for the m-DTRP that (i) are adaptive and distributed, and (ii) have strong performance guarantees in heavy-load conditions and stabilize the system in any load condition
Cooperative Networked Control of Dynamical Peer-to-Peer Vehicle Systems( )

1 edition published in 2007 in English and held by 1 WorldCat member library worldwide

The goal of this MURI center was the development of a rigorous theoretical foundation, and scalable analytical tools and paradigms for construction of networked control for large numbers of autonomous and semi-autonomous air vehicles. The research is specifically aimed at the critical reliability and performance issues facing autonomous vehicle systems which operate in highly uncertain environments, and enables the vehicles to form teams, manage information, and coordinate operations including deployment, task allocation and search. The program produced both the fundamental theory necessary to allow systematic performance analysis, verification and validation of such systems, as well as algorithms for implementation, and design software
