Download or read book Design and Fabrication of a Hybrid Neuroprosthetic Exoskeleton for Gait Restoration written by Valerie A. Weaver and published by . This book was released on 2017 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the design, fabrication, and testing of a new lower-limb exoskeleton including back-drivable knee joints assisted by electric motors and hydraulic braking. The goal is to provide gait restoration to individuals with paraplegia by coupling the externally powered motor driven exoskeleton with functional electrical stimulation of the user's muscles. The intention is to improve performance and reduce weight compared to the previous passive hydraulic design in order to further improve device efficiency and utility for the user. The design process and fabrication methods are described in this document. This work has resulted in a decrease in unit weight of 36.8% over the previous version, a maximum knee joint power-assist torque output of 35.9 Nm, a locking torque of 40 Nm, and characterized passive resistance at multiple angular velocities.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis details the design and fabrication of an advanced, hydraulically actuated exoskeleton, with the intention of decreasing weight and increasing performance over a previous proof of concept device. The initial device was invented to provide a method of gait restoration to individuals with paraplegia. It combines two different ideas - functional electrical stimulation of the user's muscles, and an external, hydraulically actuated exoskeleton. By incorporating the user's own muscles, this method is theoretically more energy efficient than other alternatives while providing additional health benefits. However, in order to fully realize these advantages, the device must be made smaller and lighter, in order to decrease the overhead energy requirements placed on the user's own muscular system. To accomplish this, a new exoskeleton was designed, that utilizes all off the advanced manufacturing and fabrication resources of the department. Part count has decreased at the cost of manufacturing complexity, and the use of aluminum and carbon fiber composite material is now prevalent in the device. Neither the hydraulic system nor the controller was modified in any way during this process. The end result of this work is a substantial decrease in overall unit weight (30%), and an estimated decrease in user energy requirements of approximately 15.2%. This was accomplished while maintaining all previous benchmarks in range of motion. It is expected that this will have a positive influence on the operation of the device, particularly in planned future endeavors in stair climbing. Future work in this area to further increase device performance can take place in integration and redesign of all hydraulic components - replacing the existing brass pieces with lightweight, high operating pressure, potentially seal free pieces made from high strength, aerospace grade 7000 series aluminum.

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.
