Download or read book Design of a Hydraulic Low-speed, High-torque, Cycloidal Actuator/motor for Use in Medical Devices written by and published by . This book was released on 2014 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis presents the design of a meso-scale, hydraulic, rotary actuator/motor. While there are some existing devices, both hydraulic and pneumatic, it was ascertained that there are opportunities for other devices. Some particularly relevant devices that are discussed in the thesis are the PneuStep from John Hopkins University and a meso-scale linear actuator from Oak Ridge National Laboratory. The PneuStep is a pneumatic stepper motor for use in the MRI environment that achieves a max output torque of 5.31 lb in. (600 N mm) at an approximate speed of 15 RPM under operating pressures of 120 PSI (0.83 MPa) [1, 2]. In addition, researchers at the Oak Ridge National Laboratory (Oak Ridge, Tennessee) have developed a meso-scale linear actuator with a diameter of 0.09 in. (2.3 mm) that generates a force of 2.4 lb (10.69 N) with a stroke length of 0.3 in. (7.6 mm) [3]. The meso-scale, hydraulic, rotary actuator/motor that is the subject of this thesis incorporates an integral cycloidal speed reducer while utilizing hydraulic cylinders for actuation in a pancake-style configuration. Initial testing with a pneumatic powered rotary actuator, which was designed and fabricated, revealed a number of important considerations that were used in the final design. Piston rod side-loading, friction losses, and cylinder alignment were found to be particularly important. The final design of the hydraulic, rotary actuator/motor was limited in its pressure supply to 85 PSI but achieved a maximum holding torque of 23 lb n. (2.6 N m). A Simulink model was developed that included compressibility effects, dynamics/inertial effects, and the effects of changing effective mass moment of inertia. Simulink model runs predicted a speed of 55 RPM with a resisting torque of 4 lb in. (450 N mm). Experimental results, under similar conditions resulted in a speed of 45 RPM. The development of a novel rotary actuator may lead to further progress in the field of medical devices for situations where a low-speed, high-torque actuation is particularly suited. Furthermore, these developments add valuable design knowledge to both the fields of meso-scale hydraulic componentry and cycloidal actuators/motors.

Book excerpt: Nature is the world's foremost designer. With billions of years of experience and boasting the most extensive laboratory available, it conducts research in every branch of engineering and science. Nature's designs and capabilities have always inspired technology, from the use of tongs and tweezers to genetic algorithms and autonomous legged robots. Taking a systems perspective rather than focusing narrowly on materials or chemistry aspects, Biomimetics: Biologically Inspired Technologies examines the field from every angle. The book contains pioneering approaches to biomimetics including a new perspective on the mechanization of cognition and intelligence, as well as defense and attack strategies in nature, their applications, and potential. It surveys the field from modeling to applications and from nano- to macro-scales, beginning with an introduction to principles of using biology to inspire designs as well as biological mechanisms as models for technology. This innovative guide discusses evolutionary robotics; genetic algorithms; molecular machines; multifunctional, biological-, and nano- materials; nastic structures inspired by plants; and functional surfaces in biology. Looking inward at biological systems, the book covers the topics of biomimetic materials, structures, control, cognition, artificial muscles, biosensors that mimic senses, artificial organs, and interfaces between engineered and biological systems. The final chapter contemplates the future of the field and outlines the challenges ahead. Featuring extensive illustrations, including a 32-page full-color insert, Biomimetics: Biologically Inspired Technologies provides unmatched breadth of scope as well as lucid illumination of this promising field.

Download or read book Flying Insects and Robots written by Dario Floreano and published by Springer Science & Business Media. This book was released on 2009-10-23 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flying insects are intelligent micromachines capable of exquisite maneuvers in unpredictable environments. Understanding these systems advances our knowledge of flight control, sensor suites, and unsteady aerodynamics, which is of crucial interest to engineers developing intelligent flying robots or micro air vehicles (MAVs). The insights we gain when synthesizing bioinspired systems can in turn benefit the fields of neurophysiology, ethology and zoology by providing real-life tests of the proposed models. This book was written by biologists and engineers leading the research in this crossdisciplinary field. It examines all aspects of the mechanics, technology and intelligence of insects and insectoids. After introductory-level overviews of flight control in insects, dedicated chapters focus on the development of autonomous flying systems using biological principles to sense their surroundings and autonomously navigate. A significant part of the book is dedicated to the mechanics and control of flapping wings both in insects and artificial systems. Finally hybrid locomotion, energy harvesting and manufacturing of small flying robots are covered. A particular feature of the book is the depth on realization topics such as control engineering, electronics, mechanics, optics, robotics and manufacturing. This book will be of interest to academic and industrial researchers engaged with theory and engineering in the domains of aerial robotics, artificial intelligence, and entomology.

Download or read book Neurotechnology for Biomimetic Robots written by Joseph Ayers and published by MIT Press. This book was released on 2002 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of neurotechnology, the engineering of robots based on animals and animal behavior. The goal of neurotechnology is to confer the performance advantages of animal systems on robotic machines. Biomimetic robots differ from traditional robots in that they are agile, relatively cheap, and able to deal with real-world environments. The engineering of these robots requires a thorough understanding of the biological systems on which they are based, at both the biomechanical and physiological levels.This book provides an in-depth overview of the field. The areas covered include myomorphic actuators, which mimic muscle action; neuromorphic sensors, which, like animal sensors, represent sensory modalities such as light, pressure, and motion in a labeled-line code; biomimetic controllers, based on the relatively simple control systems of invertebrate animals; and the autonomous behaviors that are based on an animal's selection of behaviors from a species-specific behavioral "library." The ultimate goal is to develop a truly autonomous robot, one able to navigate and interact with its environment solely on the basis of sensory feedback without prompting from a human operator.
