Available in PDF, EPUB and Kindle. Book excerpt: A leap forward in the field of robotics Until now, most of the advances in robotics have taken place instructured environments. Scientists and engineers have designedhighly sophisticated robots, but most are still only able tooperate and move in predetermined, planned environments designedspecifically for the robots and typically at very high cost. Thisnew book takes robotics to the next level by setting forth thetheory and techniques needed to achieve robotic motion inunstructured environments. The ability to move and operate in anarbitrary, unplanned environment will lead to automating a widerange of new robotic tasks, such as patient care, toxic sitecleanup, and planetary exploration. The approach that opens the door for robots to handle unstructuredtasks is known as Sensing-Intelligence-Motion (SIM), which drawsfrom research in topology, computational complexity, controltheory, and sensing hardware. Using SIM as an underlyingfoundation, the author's carefully structured presentation isdesigned to: * Formulate the challenges of sensor-based motion planning and thenbuild a theoretical foundation for sensor-based motion planningstrategies * Investigate promising algorithmic strategies for mobile robotsand robot arm manipulators, in both cases addressing motionplanning for the whole robot body * Compare robot performance to human performance in sensor-basedmotion planning to gain better insight into the challenges of SIMand help build synergistic human-robot teams for tele-operationtasks. It is both exciting and encouraging to discover that robotperformance decisively exceeds human performance in certain tasksrequiring spatial reasoning, even when compared to trainedoperators * Review sensing hardware that is necessary to realize the SIMparadigm Some 200 illustrations, graphic sketches, and photos are includedto clarify key issues, develop and validate motion planningapproaches, and demonstrate full systems in operation. As the first book fully devoted to robot motion planning inunstructured environments, Sensing, Intelligence, Motion is amust-read for engineers, scientists, and researchers involved inrobotics. It will help them migrate robots from highly specializedapplications in factories to widespread use in society whereautonomous robot motion is needed.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents methods for robot teleoperation, or equivalently, human-in-the- loop robotics. Human-in-the loop systems have the potential to handle complex tasks by combining the cognitive skills of a human operator with autonomous tools and behaviors. Along these lines, we present novel methods in grasp planning, haptic (force-feedback) rendering, and robot control which allow synergy in interaction between a human operator and a robot. We describe the interfaces that employ these algorithms, and validate them through user experiments. Our goal is to see robot technologies make a bigger impact in peoples' everyday lives, getting robots out of the laboratory and factory, and into homes, offices, and other unstructured human spaces. Our algorithms focus on three distinct areas of telerobotic manipulation but are unified by their common reliance on 3D point cloud data obtained from emerging sensor technol- ogy; we do not depend on environment or object models known a priori since it difficult to anticipate the things a robot will encounter in unstructured settings. First, since grasp- ing is a prerequisite for many manipulation tasks, we present two algorithms for planning grasps on clusters of 3D points. Next, we explore how to perform force-feedback haptic rendering of 3D point cloud data. This enables an operator to use the sense of touch to learn about environment geometry and potential collisions. Finally, we present a controller that uses a sequence of convex optimization steps to produce constrained arm motions that follow time-varying goal poses commanded by an operator. Using 3D sensor data to form motion constraints in real-time, the robot is responsive to changing goals from the user yet also avoids collisions and unfavorable arm configurations. We demonstrate the integration of our algorithms into a telerobotic system that enables an operator to perform varied and unscripted manipulation tasks in arbitrary settings. We describe tools for navigation, perception, and manipulation, ranging from direct control of a gripper or mobile base to autonomous sub-modules that perform collision-free base navigation or arm motion planning. Most importantly, we share results from testing these interfaces in a variety of settings, including user studies with non-expert operators and a case study with a motor-impaired operator using the robot in his own home.

Available in PDF, EPUB and Kindle. Book excerpt: The LSU Robo-Tiger project is a joint effort involving LSU's Computer Science, Electrical Engineering, and Athletic departments. The idea was conceived by Dr. S.S. Iyengar and Dr. Lynn Jelinski late in the fall semester of 1999. The goal was to build a cybernetic tiger to be used to help the school mascot, Mike the Tiger, with his duties at the schools various athletic functions. In doing so, it was hoped the project would not only catch the imagination of the students and faculty, but also provide a viable research platform for studying various issues pertaining to mobile robots in unstructured environments. Under the direction of Dr. S.S. Iyengar, the LSU Computer Science department's Robot Research Lab has conducted preliminary studies to determine the feasibility of the project. The first phase of the project consisted of constructing, modifying and programming a small prototype of the tiger. A series of three prototypes were used to identify the various issues involved in developing a full sized robotic tiger. Although the resulting prototypes are much simplified versions of the final product, many of the ideas, concepts, algorithms and construction methods are applicable.

Available in PDF, EPUB and Kindle. Book excerpt: Autonomous robots are robots which can perform desired tasks in unstructured environments without continuous human guidance. Many kinds of robots have some degree of autonomy. Different robots can be autonomous in different ways. A high degree of autonomy is particularly desirable in fields such as space exploration, where communication delays and interruptions are unavoidable. Some modern factory robots are "autonomous" within the strict confines of their direct environment. The exact orientation and position of the next object of work and (in the more advanced factories) even the type of object and the required task must be determined. This can vary unpredictably (at least from the robot's point of view). One important area of robotics research is to enable the robot to cope with its environment whether this be on land, underwater, in the air, underground, or in space. This book presents the latest research from around the globe.

This book was released on 2012-12-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last decade, many researchers have dedicated their efforts to constructing revolutionary machines and to providing them with forms of artificial intelligence to perform some of the most hazardous, risky or monotonous tasks historically assigned to human beings. Among those machines, mobile robots are undoubtedly at the cutting edge of current research directions. A rough classification of mobile robots can be considered: on the one hand, mobile robots oriented to human-made indoor environments; on the other hand, mobile robots oriented to unstructured outdoor environments, which could include flying oriented robots, space-oriented robots and underwater robots. The most common motion mechanism for surface mobile robots is the wheel-based mechanism, adapted both to flat surfaces, found in human-made environments, and to rough terrain, found in outdoor environments. However, some researchers have reported successful developments with leg-based mobile robots capable of climbing up stairs, although they require further investigation. The research work presented here focuses on wheel-based mobile robots that navigate in human-made indoor environments. The main problems described throughout this book are: Representation and integration of uncertain geometric information by means of the Symmetries and Perturbations Model (SPmodel). This model combines the use of probability theory to represent the imprecision in the location of a geometric element, and the theory of symmetries to represent the partiality due to characteristics of each type of geometric element. A solution to the first location problem, that is, the computation of an estimation for the mobile robot location when the vehicle is completely lost in the environment. The problem is formulated as a search in an interpretation tree using efficient matching algorithms and geometric constraints to reduce the size of the solution space. The book proposes a new probabilistic framework adapted to the problem of simultaneous localization and map building for mobile robots: the Symmetries and Perturbations Map (SPmap). This framework has been experimentally validated by a complete experiment which profited from ground-truth to accurately validate the precision and the appropriateness of the approach. The book emphasizes the generality of the solutions proposed to the different problems and their independence with respect to the exteroceptive sensors mounted on the mobile robot. Theoretical results are complemented by real experiments, where the use of multisensor-based approaches is highlighted.
