This book was released on 2021-11-22 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports on the design and testing of an sEMG-based control strategy for a fully-wearable low-cost hand exoskeleton. It describes in detail the modifications carried out to the electronics of a previous prototype, covering in turn the implementation of an innovative sEMG classifier for predicting the wearer's motor intention and driving the exoskeleton accordingly. While similar classifier have been widely used for motor intention prediction, their application to wearable device control has been neglected so far. Thus, this book fills a gap in the literature providing readers with extensive information and a source of inspiration for the future design and control of medical and assistive devices.

Available in PDF, EPUB and Kindle. Book excerpt: Wearable exoskeletons are electro-mechanical systems designed to assist, augment, or enhance motion and mobility in a variety of human motion applications and scenarios. The applications, ranging from providing power supplementation to assist the wearers to situations where human motion is resisted for exercising applications, cover a wide range of domains such as medical devices for patient rehabilitation training recovering from trauma, movement aids for disabled persons, personal care robots for providing daily living assistance, and reduction of physical burden in industrial and military applications. The development of effective and affordable wearable exoskeletons poses several design, control and modelling challenges to researchers and manufacturers. Novel technologies are therefore being developed in adaptive motion controllers, human-robot interaction control, biological sensors and actuators, materials and structures, etc. In this book, the editors and authors report recent advances and technology breakthroughs in exoskeleton developments. It will be of interest to engineers and researchers in academia and industry as well as manufacturing companies interested in developing new markets in wearable exoskeleton robotics.

This book was released on 2012 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of the thesis is to develop a portable and wearable five-fingered hand exoskeleton that post-stroke patients can use to rehabilitate the hand functions back to normal levels and also assist them in their daily living. With the demographics of many developed countries expected to change dramatically, many are becoming older and the associated diseases are bound to increase. Stroke is one such disease that will likely to impair the upper limb functions on many of the elderlies. Automation of therapies on post-stroke patients is a way to improve the recovery rate and enhance the quality of lives on these patients without having to costly train more therapists. The five-fingered hand exoskeleton is bio-inspired in a sense that it tries to mimic normal human finger functions by using air muscles as the main actuator and tendon like cables to transfer the pull power. The mechanical design can be divided into 3 major groups: finger module assemblies, dorsal plate assembly and actuator housing assembly. With portability and wearability as the main goals, light materials such ABS plastics, PLA plastics and aluminium were utilised to construct the hand exoskeleton. In this prototype, two control functions are implemented, as a rehabilitative device the exoskeleton perform certain exercise movements to mimic the function of a therapist and as an assistive device the exoskeleton can assist the user in grasping everyday's object such as coffee cups. When rehabilitative mode is selected, position sensor in a form rubber strip coated with polypyrrole feedbacks voltage signals which then translated into the controlled variable of joint angles. As an assistive device, 4 Flexiforce® sensors are used to detect grip intensity of the exoskeleton which can hold cylindrical objects. To control the finger movements, PID controllers embedded within LabVIEW were utilised and the user interacts via the Graphical User Interface (GUI) on the computer. To connect the software (LabVIEW) with the hand exoskeleton, hardware in the form of data acquisition devices, pneumatic solenoid valves and electronic interface circuitries were implemented. On average the exoskeleton is able to replicate 81% of normal human Range of Motion (ROM). As a rehabilitative device, the controllers were tuned in such a way that the controlled joint angles will always be below the set joint angles so no injuries from over-actuations can occur. As an assistive device, the exoskeleton can provide assistive force to lift coffee cups up to a weight of 413 g. This work has shown the possibility of using bio-mechatronics device as a way to rehabilitate post-stroke patients during their recovery and assist them during their daily living.
Download or read book A Hand Exoskeleton with Series Elastic Actuation for Rehabilitation written by Priyanshu Agarwal and published by . This book was released on 2017 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rehabilitation of the hands is critical for restoring independence in activities of daily living for individuals with upper extremity disabilities. Conventional therapies for hand rehabilitation have not shown significant improvement in hand function. Robotic exoskeletons have been developed to assist in therapy and there is initial evidence that such devices with force-control based strategies can help in effective rehabilitation of human limbs. However, to the best of our knowledge, none of the existing hand exoskeletons allow for accurate force or torque control. In this dissertation, we design and prototype a novel hand exoskeleton that has the following unique features: (i) Bowden-cable-based series elastic actuation allowing for bidirectional torque control of each joint individually, (ii) an underlying kinematic mechanism that is optimized to achieve large range of motion and (iii) a thumb module that allows for independent actuation of the four thumb joints. To control the developed hand exoskeleton for efficacious rehabilitation after a neuromuscular impairment such as stroke, we present two types of subject-specific assist-as-needed controllers. Learned force-field control is a novel control technique in which a neural-network-based model of the required torques given the joint angles for a specific subject is learned and then used to build a force-field to assist the joint motion of the subject to follow a trajectory designed in the joint-angle space. Adaptive assist-as-needed control, on the other hand, estimates the coupled digit-exoskeleton system torque requirement of a subject using radial basis function (RBF) and on-the-y adapts the RBF magnitudes to provide a feed-forward assistance for improved trajectory tracking. Experiments with healthy human subjects showed that each controller has its own trade-offs and is suitable for a specific type of impairment. Finally, to promote and optimize motor (re)-learning, we present a framework for robot-assisted motor (re)-learning that provides subject-specific training by allowing for simultaneous adaptation of task, assistance and feedback based on the performance of the subject on the task. To train the subjects for dexterous manipulation, we present a torque-based task that requires subjects to dynamically regulate their joint torques. A pilot study carried out with healthy human subjects using the developed hand exoskeleton suggests that training under simultaneous adaptation of task, assistance and feedback can module challenge and affect their motor learning.

Download or read book Research Anthology on Emerging Technologies and Ethical Implications in Human Enhancement written by Management Association, Information Resources and published by IGI Global. This book was released on 2020-12-18 with total page 791 pages. Available in PDF, EPUB and Kindle. Book excerpt: Along with the introduction of technology in nearly every facet of human life comes the question of the ethical side of using technology to improve the human condition, whether that be physically or mentally. The capabilities of human enhancement technologies have created a dual-sided approach to discussing human enhancement: the critical approach of attempting to reach human perfection and the ethics within that idea and the endless capabilities of technology that have greatly impacted the medical field. It is essential to discuss both aspects within these emerging technologies, whether as separate entities or as cohesive units. Ranging from disease detection and treatment to implants and prosthetics to robotics and genetic engineering, human enhancement technologies are widespread and multi-purposed. By going beyond the capabilities of human hands, these technologies have propelled modern medicine and healthcare to new levels that have allowed humans to face new treatments or assistive technologies not seen before. The Research Anthology on Emerging Technologies and Ethical Implications in Human Enhancement covers the primary technologies and tools being used in medicine and healthcare along with discussions on the ethics of enhancing the human body. Topics covered include prosthetics and implants, robotics, human disorders/diseases and treatments and smart technologies, along with law and theory. This publication serves as a valuable reference work for doctors, medical professionals, researchers, students, professionals, and practitioners involved in fields that include ethics, medicine, computer science, robotics, genetics, assistive technologies, nanotechnology, biomedical engineering, and biotechnology.

Download or read book Wearable Robots written by José L. Pons and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wearable robot is a mechatronic system that is designed around the shape and function of the human body, with segments and joints corresponding to those of the person it is externally coupled with. Teleoperation and power amplification were the first applications, but after recent technological advances the range of application fields has widened. Increasing recognition from the scientific community means that this technology is now employed in telemanipulation, man-amplification, neuromotor control research and rehabilitation, and to assist with impaired human motor control. Logical in structure and original in its global orientation, this volume gives a full overview of wearable robotics, providing the reader with a complete understanding of the key applications and technologies suitable for its development. The main topics are demonstrated through two detailed case studies; one on a lower limb active orthosis for a human leg, and one on a wearable robot that suppresses upper limb tremor. These examples highlight the difficulties and potentialities in this area of technology, illustrating how design decisions should be made based on these. As well as discussing the cognitive interaction between human and robot, this comprehensive text also covers: the mechanics of the wearable robot and it’s biomechanical interaction with the user, including state-of-the-art technologies that enable sensory and motor interaction between human (biological) and wearable artificial (mechatronic) systems; the basis for bioinspiration and biomimetism, general rules for the development of biologically-inspired designs, and how these could serve recursively as biological models to explain biological systems; the study on the development of networks for wearable robotics. Wearable Robotics: Biomechatronic Exoskeletons will appeal to lecturers, senior undergraduate students, postgraduates and other researchers of medical, electrical and bio engineering who are interested in the area of assistive robotics. Active system developers in this sector of the engineering industry will also find it an informative and welcome resource.
