Book excerpt: The recent rapid development of computing, communication and sensing technologies triggers the prevalence of multi-robot systems. Compared to single-robot systems, multi-robot systems are advantageous in three aspects: 1) they can accomplish tasks which are beyond the capabilities of single robots; 2) they are cheaper and more flexible for certain tasks; 3) control scheme of multi-robot systems may reveal insights into key issues in social and life sciences. Multi-robot systems have numerous applications in various areas, such as traffic coordination and precision agriculture. Robotic motion planning is a fundamental problem where a sequence of controls are identified to steer robots to goal regions subject to geometric and dynamic constraints. However, the problem is computationally hard even for a single robot. The generalized mover's problem is shown to be PSPACE-hard in degrees of freedom. The optimal motion planning, where the aggregate cost along the returned trajectory is minimized, is more computationally challenging. It is shown that computing the shortest path in R^3 populated with obstacles is NP-hard in the number of obstacles. Multi-robot motion planning is even harder than its single-robot counterpart and its worst-case computational complexity grows exponentially in the number of robots. In this dissertation, we aim to study multi-robot optimal motion planning and design a set of planners towards scalability and optimality. Our research is three-fold. We first investigate the scenario where a team of robots desire to arrive at their own goal regions as soon as possible. The robots are governed by complex dynamics and need to maintain safe distance from static obstacles and other robots. The optimality of the solution is characterized by Pareto optimality, where the reduction of one robot's travelling time must cause the rise of others'. A novel numerical algorithm is proposed to identify the Pareto optimal solutions where no robot can unilaterally reduce its traveling time without extending others'. The consistent approximation of the algorithm in the epigraphical profile sense is guaranteed using set-valued numerical analysis. Experiments on an indoor multi-robot platform and computer simulations show the anytime property of the proposed algorithm; i.e., it is able to quickly return a feasible control policy that safely steers the robots to their goal regions and it keeps improving policy optimality if more time is given. Then we propose a distributed algorithm to achieve much better scalability. Specifically, the algorithm integrates decoupled optimal feedback planning and distributed conflict resolution to coordinate a fleet of unicycle robots. Each robot independently generates its optimal motions offline and avoids collisions with other objects in online execution. The computational complexity is independent of the robot number. Moreover, each robot's individual planner is optimal and its motion is rarely interfered in exercise, so the algorithm is near-optimal. Collision avoidance and finite-time arrival at the goal regions are formally guaranteed. A set of simulations are conducted to verify the scalability and near-optimality of the proposed algorithm. Lastly, we propose a distributed optimal motion planning algorithm for heterogeneous multi-robot systems and strongly coupled missions to balance scalability and optimality, where multiple robots of different dynamics desire to safely reach their respective goal regions with minimal cost. Each robot shares its policy with others in parallel and takes best response with respect to others' policies in a sequential fashion. The proposed algorithm is shown to converge to the optimal value function, and the computational complexity is linear with respect to robot number but is much smaller than benchmark. A set of simulations are conducted to verify the scalability and near-optimality of the proposed algorithm.

Available in PDF, EPUB and Kindle. Book excerpt: Algorithms are a fundamental component of robotic systems. Robot algorithms process inputs from sensors that provide noisy and partial data, build geometric and physical models of the world, plan high-and low-level actions at different time horizons, and execute these actions on actuators with limited precision. The design and analysis of robot algorithms raise a unique combination of questions from many elds, including control theory, computational geometry and topology, geometrical and physical modeling, reasoning under uncertainty, probabilistic algorithms, game theory, and theoretical computer science. The Workshop on Algorithmic Foundations of Robotics (WAFR) is a single-track meeting of leading researchers in the eld of robot algorithms. Since its inception in 1994, WAFR has been held every other year, and has provided one of the premiere venues for the publication of some of the eld's most important and lasting contributions. This books contains the proceedings of the tenth WAFR, held on June 13{15 2012 at the Massachusetts Institute of Technology. The 37 papers included in this book cover a broad range of topics, from fundamental theoretical issues in robot motion planning, control, and perception, to novel applications.

Available in PDF, EPUB and Kindle. Book excerpt: The Complexity of Robot Motion Planning makes original contributions both to roboticsand to the analysis of algorithms. In this groundbreaking monograph John Canny resolveslong-standing problems concerning the complexity of motion planning and, for the central problem offinding a collision free path for a jointed robot in the presence of obstacles, obtains exponentialspeedups over existing algorithms by applying high-powered new mathematical techniques.Canny's newalgorithm for this "generalized movers' problem," the most-studied and basic robot motion planningproblem, has a single exponential running time, and is polynomial for any given robot. The algorithmhas an optimal running time exponent and is based on the notion of roadmaps - one-dimensionalsubsets of the robot's configuration space. In deriving the single exponential bound, Cannyintroduces and reveals the power of two tools that have not been previously used in geometricalgorithms: the generalized (multivariable) resultant for a system of polynomials and Whitney'snotion of stratified sets. He has also developed a novel representation of object orientation basedon unnormalized quaternions which reduces the complexity of the algorithms and enhances theirpractical applicability.After dealing with the movers' problem, the book next attacks and derivesseveral lower bounds on extensions of the problem: finding the shortest path among polyhedralobstacles, planning with velocity limits, and compliant motion planning with uncertainty. Itintroduces a clever technique, "path encoding," that allows a proof of NP-hardness for the first twoproblems and then shows that the general form of compliant motion planning, a problem that is thefocus of a great deal of recent work in robotics, is non-deterministic exponential time hard. Cannyproves this result using a highly original construction.John Canny received his doctorate from MITAnd is an assistant professor in the Computer Science Division at the University of California,Berkeley. The Complexity of Robot Motion Planning is the winner of the 1987 ACM DoctoralDissertation Award.

Download or read book Robot Path Planning and Cooperation written by Anis Koubaa and published by Springer. This book was released on 2018-04-05 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents extensive research on two main problems in robotics: the path planning problem and the multi-robot task allocation problem. It is the first book to provide a comprehensive solution for using these techniques in large-scale environments containing randomly scattered obstacles. The research conducted resulted in tangible results both in theory and in practice. For path planning, new algorithms for large-scale problems are devised and implemented and integrated into the Robot Operating System (ROS). The book also discusses the parallelism advantage of cloud computing techniques to solve the path planning problem, and, for multi-robot task allocation, it addresses the task assignment problem and the multiple traveling salesman problem for mobile robots applications. In addition, four new algorithms have been devised to investigate the cooperation issues with extensive simulations and comparative performance evaluation. The algorithms are implemented and simulated in MATLAB and Webots.

Available in PDF, EPUB and Kindle. Book excerpt: A successful motion planning algorithm was designed and implemented on multiple high performance KheperaIII robots. 2 KheperaIII robots finds a dynamic path from the specified source to the targeted destination avoiding collisions in an unpredictable environment processing real-time data exchanged within robots by distributed communication on a well-spaced grid where boundaries are used as landmarks ascertained by the infrared sensors. Distributed communication was implemented by implementing server and client on every robot in the system with the help of multi-threads. This algorithm hence, is successful implementation in the field of motion planning and coordination with autonomous robots. Also in this thesis, is explained the centralized and decoupled behavior of the motion planning algorithms on the multi robots. The implementation of the algorithm over KheperaIII robots aimed at representing the successfulness of this technique in practical cases, as the work in this field is still relatively new.

Download or read book Robot Motion Planning written by Jean-Claude Latombe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the ultimate goals in Robotics is to create autonomous robots. Such robots will accept high-level descriptions of tasks and will execute them without further human intervention. The input descriptions will specify what the user wants done rather than how to do it. The robots will be any kind of versatile mechanical device equipped with actuators and sensors under the control of a computing system. Making progress toward autonomous robots is of major practical inter est in a wide variety of application domains including manufacturing, construction, waste management, space exploration, undersea work, as sistance for the disabled, and medical surgery. It is also of great technical interest, especially for Computer Science, because it raises challenging and rich computational issues from which new concepts of broad useful ness are likely to emerge. Developing the technologies necessary for autonomous robots is a formidable undertaking with deep interweaved ramifications in auto mated reasoning, perception and control. It raises many important prob lems. One of them - motion planning - is the central theme of this book. It can be loosely stated as follows: How can a robot decide what motions to perform in order to achieve goal arrangements of physical objects? This capability is eminently necessary since, by definition, a robot accomplishes tasks by moving in the real world. The minimum one would expect from an autonomous robot is the ability to plan its x Preface own motions.

This book was released on 2019 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: As robots become mechanically more capable, they are going to be more and more integrated into our daily lives. Over time, human0́9s expectation of what the robot capabilities are is getting higher. Therefore, it can be conjectured that often robots will not act as human commanders intended them to do. That is, the users of the robots may have a different point of view from the one the robots do. The first part of this dissertation covers methods that resolve some instances of this mismatch when the mission requirements are expressed in Linear Temporal Logic (LTL) for handling coverage, sequencing, conditions and avoidance. That is, the following general questions are addressed: * What cause of the given mission is unrealizable? * Is there any other feasible mission that is close to the given one? In order to answer these questions, the LTL Revision Problem is applied and it is formulated as a graph search problem. It is shown that in general the problem is NP-Complete. Hence, it is proved that the heuristic algorihtm has 2-approximation bound in some cases. This problem, then, is extended to two different versions: one is for the weighted transition system and another is for the specification under quantitative preference. Next, a follow up question is addressed: * How can an LTL specified mission be scaled up to multiple robots operating in confined environments? The Cooperative Multi-agent Planning Problem is addressed by borrowing a technique from cooperative pathfinding problems in discrete grid environments. Since centralized planning for multi-robot systems is computationally challenging and easily results in state space explosion, a distributed planning approach is provided through agent coupling and de-coupling. In addition, in order to make such robot missions work in the real world, robots should take actions in the continuous physical world. Hence, in the second part of this thesis, the resulting motion planning problems is addressed for non-holonomic robots. That is, it is devoted to autonomous vehicles0́9 motion planning in challenging environments such as rural, semi-structured roads. This planning problem is solved with an on-the-fly hierarchical approach, using a pre-computed lattice planner. It is also proved that the proposed algorithm guarantees resolution-completeness in such demanding environments. Finally, possible extensions are discussed.
