This book was released on 2020 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: An expanding literature base has applied Supernumerary Robotic Limbs (Superlimbs) to fields as diverse as heavy industry, robotic surgery, and assistive technology. While the list of applications has grown, and the designs have become more diverse, the research community has focused almost exclusively on the robotic system's role in augmenting the humans capabilities. This represents only one side of the issue; little research has explored the role of the human operator. This thesis represents the first in-depth exploration of the humans contributions to the Superlimb-human system. We began by examining the control strategy of Superlimbs by asking whether fully manual control of the Superlimbs was viable when the human operator was asked to perform simultaneous and independent tasks with both their robotic and natural limbs. Although we found that the human operator was able to control all four limbs-two robotic, two natural-simultaneously, we found that the human operator performed worse with their natural limbs when controlling all four limbs as compared to when the human operator was only controlling their natural limbs. Thus, when designing Superlimbs for a task set that requires the human and the robot to perform simultaneous independent tasks, this study points to the need for reducing the number of Superlimb degrees of freedom (DOFs) the human must manually control either through design or control. In order to achieve this reduction, we next exploited the high redundancy and flexibility of the human body. First, we proposed a methodology for reduced-actuator Superlimbs by exploiting the human operators' ability to manipulate the base of the Superlimb. Based upon this methodology, we realized a lightweight Superlimb that could assist a human operator by opening a door when the human operator's hands are busy. Second, we proposed a novel control input methodology for communicating a rich variety of commands to the Superlimbs while both hands are busy. Based upon this methodology, and in combination with an intermittent control structure, we controlled the reduced-actuator Superlimb described above with action primitives to assist a human operator by opening a door when the human operator was holding a large box. Finally, as the Superlimb's state changes, that change is reflected as a change in the forces and torques felt by the human operator at the base of the Superlimb. We found that this inherent haptic feedback allowed the operator to both perform closed-loop manually control of the force output of a Superlimb and to supervise the autonomous actions of a Superlimb. In sum, this thesis explores how Superlimbs can be designed to exploit the benefits while limiting the challenges of being attached to a human operator.

Available in PDF, EPUB and Kindle. Book excerpt: Humans possess the remarkable ability to control their four natural limbs in a voluntary, accurate and independent manner. The simultaneous use of two or more limbs allows humans to learn and robustly perform a wide range of complex tasks. Since the use of multiple limbs enables humans to master advanced motor skills, it would be interesting to study whether having additional limbs would enable users to expand their skill set beyond its natural limits. Inspired by this vision, we propose a new form of human augmentation: a wearable robot that augments its user by providing him with an additional set of robotic limbs. We named this new device Supernumerary Robotic Limbs (SRL). However, humans have never had the possibility to control additional, powered limbs besides their natural arms and legs. The main theme of this thesis, besides realizing a prototype of the robot and proving its usefulness in realworld tasks, is demonstrating that humans can voluntarily control additional limbs as if they were a part of their own body. We realized a lightweight (3.5 kg), comfortable prototype of the SRL that can be easily worn by an unassisted user. Two robotic limbs can assist the user in both manufacturing and locomotion tasks. We created control strategies that take advantage of the independence of the robotic limbs, enabling them to provide optimal assistance in specific tasks such as weight support, body stabilization, using powered tools, sitting/standing and dynamic walking. Finally, we developed an EMG-based control interface that enables users to voluntarily control the motion of the robotic limbs, without interfering with the posture of the rest of the body. The new augmentation technology presented in this thesis opens up new possibilities in the field of wearable robotics. The voluntary control of additional robotic limbs falls within the range of motor skills that humans can learn, and enables the acquisition of a new set of complex skills that would not be achievable using only the natural body..

Download or read book Design and Control of Supernumerary Robotic Limbs for Near ground Work written by Daniel Kurek and published by . This book was released on 2017 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supernumerary Robotic Limbs (SRLs) are a recent form of robot that augment natural human abilities through the addition of body-mounted robotic appendages which can move independently of the wearer. This thesis provides a detailed analysis of the MantisBot, an SRL morphology that provides a wearer with two torso-mounted limbs that support the body in crawling- and kneeling-like positions, such that the wearer's natural arms are free to do useful work near the ground. First, the concept and its motivations are discussed, followed by a biomechanical analysis of the human-robot system. Two full-scale prototypes are then introduced, and control laws used in supporting a wearer's body both statically using impedance control, and dynamically using predictive models of natural crawling gaits, are developed. Finally, the system is experimentally validated, and it is concluded that SRLs for near-ground work are a valid and useful tool for improving worker comfort and productivity.

Download or read book Supernumerary Robotic Limbs for Human Augmentation in Overhead Assembly Tasks written by Lawrence Zack Bright and published by . This book was released on 2017 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manufacturing tasks are highly demanding of work, and there is an especially high prevalence of injury associated with overhead tasks which are taxing to the shoulder and upper body. To assist workers completing these tasks, and to increase overall productivity, safety and effectiveness, we introduce a novel design of Supernumerary Robotic Limb (SRL). This is a robotic arm worn on the shoulder of the technician/- worker which extends the human capability with implicit force control algorithms that allow for intuitive control and interface of the extra robot arm. Affectionately dubbed Aucto, the robotic arm can lift an object and hold it while the wearer is securing the object using a tool with both hands. The worker does not have to take a laborious posture for a long time, reducing fatigue and injuries. Furthermore, a single worker can execute the task, which would otherwise require two workers. Two technical challenges and novel solutions are presented. One is to make the wearable robot simple and lightweight with use of a new type of granular jamming gripper that can grasp diverse objects from an arbitrary direction. This eliminates the need for orienting the gripper against the object with three-axis wrist joints, reducing the number of degrees of freedom (DOF) from 6 to 3. The other is an effective control algorithm that allows the wearer to move freely while the robot on the shoulder is holding an object. Unlike a robot sitting on a floor, the SRL worn by a human is disturbed by the movement of the wearer. An admittance-based control algorithm allows the robot to hold the object stably and securely despite the human movement and changes in posture. A 3 DOF prototype robot with a new granular jamming gripper and an ergonomic body mounting gear is developed and tested. It is demonstrated that the robot can hold a large object securely in the overhead area despite the movement of the wearer while performing an assembly work.
Download or read book Foot controlled Supernumerary Robotic Arm written by Zachary Joseph Dougherty and published by . This book was released on 2018 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supernumerary robotic limbs (SRLs) are extra robotic appendages that help a user with various tasks. A challenge with SRLs is how to operate them effectively. One solution is to use the foot to teleoperate the arm, freeing the person to use their arms for other tasks. However, unlike hand interfaces, it is not known how to create effective foot control for robotic teleoperation. A foot interface is developed for an experiment to compare position and rate control with the foot. Position control is shown to be more effective than rate control for 2D positioning tasks. Even if an effective control strategy is implemented, it is currently unknown if a person has the ability to control a robot with their foot while simultaneously using both arms. A second experiment shows that humans can operate an SRL with the foot while performing a task with both hands.

Download or read book Supernumerary Robotic Limbs written by Clark Michael Davenport and published by . This book was released on 2013 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the workforce within manufacturing grows older, especially within aircraft manufacturing, the need for new technologies to assist workers arises. If a technology could offer improvements to an aircraft manufacturing laborer's efficiency, as well as reduce the load on his body, it could potentially see vast use. This thesis discusses a potential solution to these issues - the Supernumerary Robotic Limbs (SRL). These limbs could potentially increase the workspace of the human operator to him more efficient, as well as reduce the load on the human while he performs staining tasks. It accomplishes this by providing the worker with extra arms in the form of a wearable backpack. This thesis first evaluates how the torques imposed on a human are affected when he uses an SRL-like device to help bear a static load. It is shown that the human work load necessary to bear such a load is reduced substantially. The second focus of this thesis is the skill acquisition. A data-driven approach is taken to learn trajectories and a leader-follower coordination relationship. This is done by generating teaching data representing trajectories and coordination information with two humans, then transferring the pertinent information to a robot that assumes the role of the follower. This coordination is validated in a simple one-dimension example, and is implemented on a robot that coordinates with a human leader during a control-box wiring task.
Download or read book Foot controlled Supernumerary Robotic Arm written by Brandon William Rudolph and published by . This book was released on 2019 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: A supernumerary robotic limb (SRL) is a robotic limb that can act as an extra arm or leg for a human user. An unsolved issue with SRLs is how to operate them well. One possibility is to control an SRL with the foot, which offers the benefit of a third arm because the user's arms remain unoccupied. While hand interfaces are common, foot interfaces are not well understood. Developing a good foot interface is challenging because of differences between feet and hands, such as the larger inertia of the leg. This thesis presents work to determine some design principles for foot interfaces. First, an experiment is done to test if the addition of friction to a foot interface can improve performance. The results show that friction can help a user stop and hold position without reducing the dynamic performance of the user. A second experiment looks at the performance of isometric interfaces, which, unlike isotonic interfaces, use force inputs rather than motion. Isotonic interfaces generally outperformed isometric, although there were only small differences between rate control for both isotonic and isometric. Additionally, rate control was found to be better than position control for the isometric interface. Finally, an experiment was conducted to evaluate how well a human user can use a foot-controlled SRL to coordinate motion with both of their hands. People showed that they could reliably use their foot in conjunction with their hands to perform a two-dimensional positioning task better than they can with just two hands, and with performance resembling that of two human users.
Download or read book Human Robotics written by Etienne Burdet and published by MIT Press. This book was released on 2013-09-13 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: A synthesis of biomechanics and neural control that draws on recent advances in robotics to address control problems solved by the human sensorimotor system. This book proposes a transdisciplinary approach to investigating human motor control that synthesizes musculoskeletal biomechanics and neural control. The authors argue that this integrated approach—which uses the framework of robotics to understand sensorimotor control problems—offers a more complete and accurate description than either a purely neural computational approach or a purely biomechanical one. The authors offer an account of motor control in which explanatory models are based on experimental evidence using mathematical approaches reminiscent of physics. These computational models yield algorithms for motor control that may be used as tools to investigate or treat diseases of the sensorimotor system and to guide the development of algorithms and hardware that can be incorporated into products designed to assist with the tasks of daily living. The authors focus on the insights their approach offers in understanding how movement of the arm is controlled and how the control adapts to changing environments. The book begins with muscle mechanics and control, progresses in a logical manner to planning and behavior, and describes applications in neurorehabilitation and robotics. The material is self-contained, and accessible to researchers and professionals in a range of fields, including psychology, kinesiology, neurology, computer science, and robotics.
