Grasping at Gravity


Book Description

Sometimes you find yourself at the end of your tether. A ring of reverse half gravity encircles the globe, the result of a cataclysmic event that occurred 500 years in the past. Tallow has been performing the duties of a scout for years and all he knows is that life is difficult at the base of the swath. He travels along the edges of the limen, a threshold separating the earth-bound from the sky-bound - a border the tether tribes have never dared to cross. One misstep could cost him his life. While scouting for resources, Tallow encounters something he's never seen before, a woman, one with knowledge about his people that she shouldn't have - and a warning. Her allegations couldn't possibly be true, they lived in different worlds. Her people couldn't cross over to learn about his people any more than the tribes could cross over to learn about hers. The problem is, he can't get her out of his mind, and soon learns that a dangerous lie underpins everything he has ever known.

The Grasping Hand


Book Description

The simple task of grasping objects has been studied for centuries by scientists, therapists and engineers who have tried to understand and duplicate the versatility of the human hand. Using an interdisciplinary approach and new framework for looking at prehension, the authors uncover the subleties of the amazing interaction between the hand and the brain. They draw from such diverse fields as experimental psychology, kinesiology, robotics, neural networks, artificial intelligence, neuropsychology and rehabilitation. A triangle strategy is presented, starting from conceptual models that suggest both experimental and computational models. Chapters describe the multiple postures established by the hand, phases in the dynamic process of reaching for, grasping and manipulating various objects, and the constraints acting on such activity. Appendices provide the complete anatomy of the upper limb, the basics of computational modelling, and the fundamentals of prosthetic and dextrous robot hands. The ultimate goal of this book is to develop a common vocabularly for multidisciplinary researchers who strive to understand a system as complex as the hand under the control of the human brain.




Modern Robotics


Book Description

Reach-to-Grasp Behavior


Book Description

Reaching for objects in our surroundings is an everyday activity that most humans perform seamlessly a hundred times a day. It is nonetheless a complex behavior that requires the perception of objects’ features, action selection, movement planning, multi-joint coordination, force regulation, and the integration of all of these properties during the actions themselves to meet the successful demands of extremely varied task goals. Even though reach-to-grasp behavior has been studied for decades, it has, in recent years, become a particularly growing area of multidisciplinary research because of its crucial role in activities of daily living and broad range of applications to other fields, including physical rehabilitation, prosthetics, and robotics. This volume brings together novel and exciting research that sheds light into the complex sensory-motor processes involved in the selection and production of reach-to-grasp behaviors. It also offers a unique life-span and multidisciplinary perspective on the development and multiple processes involved in the formation of reach-to-grasp. It covers recent and exciting discoveries from the fields of developmental psychology and learning sciences, neurophysiology and brain sciences, movement sciences, and the dynamic field of developmental robotics, which has become a very active applied field relying on biologically inspired models. This volume is a rich and valuable resource for students and professionals in all of these research fields, as well as cognitive sciences, rehabilitation, and other applied sciences.

Encyclopedia of Perception


Book Description

The field of perception is devoted to explaining the operation of the senses and the experiences and behaviors resulting from stimulation of the senses. Perceptual processes such as recognizing faces, seeing color, hearing music, and feeling pain represent the actions of complex mechanisms, yet we usually do them easily. The Encyclopedia of Perception presents a comprehensive overview of the field of perception through authoritative essays written by leading researchers and theoreticians in psychology, the cognitive sciences, neuroscience, and medical disciplines. It presents two parallel and interacting approaches: the psychophysical, or determining the relationship between stimuli in the environment and perception, and the physiological, or locating the biological systems responsible for perception. Are there any processes not associated with perception? Surely there are, but the pervasiveness of perception is truly impressive, and the phenomena of perception and its mechanisms are what this encyclopedia is about. Key Features Contains 16 pages of color illustration and photography to accompany the entries Offers a varied and broad list of topics, including basic research as well as methodologies, theoretical approaches, and real-world applications of perceptual research Emphasizes human perception but includes ample research because of its importance in its own right and because of what this research tells us about human perception Written by recognized experts from many disciplines but for an audience with no previous background in perception—students and members of the general public alike Key Themes Action Attention Audition Chemical Senses Cognition and Perception Computers and Perception Consciousness Disorders of Perception Illusory Perceptions Individual Differences (Human) and Comparative (Across Species; Not Including Ageing, Disorders, and Perceptual Development) Methods Perceptual Development/Experience Philosophical Approaches Physiological Processes Sense Interaction Skin and Body Senses Theoretical Approaches Visual Perception




Fundamentals Of Robotic Grasping And Fixturing


Book Description

This book provides a fundamental knowledge of robotic grasping and fixturing (RGF) manipulation. For RGF manipulation to become a science rather than an art, the content of the book is uniquely designed for a thorough understanding of the RGF from the multifingered robot hand grasp, basic fixture design principle, and evaluating and planning of robotic grasping/fixturing, and focuses on the modeling and applications of the RGF. Compared with existing publications, this volume concentrates more on abstract formulation, i.e. mathematical modeling of robotic grasping and fixturing. Thus, it will be a good reference text for academic researchers, manufacturing and industrial engineers and a textbook for engineering graduate students.The book provides readers an overall picture and scientific basis of RGF, the comprehensive information and mathematic models of developing and applying RGF in industry, and presents long term valuable information which is essential and can be used by technical professions as a good reference.
