Book Description
The field of robot-assisted rehabilitation has seen significant development in recent years. With the development of compliant robots that can be safely used in proximity to people, the use of robots to assist rehabilitation has increased rapidly. The need for gait rehabilitation robots arises from the increasing number of people who are affected by conditions that impair their ability to walk. These conditions can include neurological disorders such as strokes, spinal cord injuries, and traumatic brain injuries. In traditional gait rehabilitation, patients receive manual therapy from a team of physical therapists. While manual therapy can be effective, it can also be time-consuming and resource-intensive, and therapists may not be able to provide consistent and precise support to patients. Gait rehabilitation robots, on the other hand, provide a consistent and precise form of therapy that may help patients make faster and more significant progress. Gait rehabilitation robots can also help reduce the physical demands on therapists and improve the efficiency of therapy sessions. This can allow more patients to receive therapy, which can improve access to care and reduce the burden on health care systems. However, most of existing robotic orthoses have not applied appropriate self-aligning mechanism, gravity-balancing mechanism, or compliant actuators. These limitations should be considered in this proposed research. This thesis proposes a novel intrinsically compliant gait rehabilitation robot with multiple actuated degrees-of-freedom (DOFs). The robot design is flexible and can be personalised with the use of telescopic pelvis, thigh, and shank sections. This newly designed rehabilitation robotic orthosis has multiple actuated and passive DOFs. Because of the importance of alignment between the designed rehabilitation robot joints and human anatomical joints, the robot design has a self-aligning mechanism. A novel gear-couple mechanism, toothed cam-couple mechanism and four-bar linkage mechanism are designed and applied to the hip, knee, and ankle joints to align the robot joints with anatomical joints during gait rehabilitation. Simulation-based and motion capture system-based tests are applied to those three mechanisms to evaluate and choose the most effective self-aligning mechanism. The gear-couple mechanism is finally chosen to be applied to the prototype design. A partial gravity-balancing mechanism is also applied to the designed rehabilitation robot. Gravity-balancing can help overcome the inertia of the rehabilitation robot and can further help reduce joint misalignment. The compliance in the robot is intrinsic due to the use of pneumatic muscle actuators (PMAs). The PMAs have been carefully selected to provide the required torques at the hip, knee and ankle joints during gait rehabilitation. Mechanical amplification of the actuation from the PMAs has been achieved by using gear-couples to replace the usual revolute robot joints. However, with the increase in flexibility of the designed prototype and application of PMAs, which are nonlinear actuators, it is challenging to design the robot control system. This challenge was overcome by developing a system dynamic identification model based on the Koopman operator for the design of a nonlinear model predictive controller (NMPC). The new robot design, together with its self-aligning and gravity-balancing mechanisms, is discussed in detail in this thesis. Compliant actuation and its amplification are explained and various algorithms that are designed and implemented on the robot system as robot firmware are explained. A NMPC is designed and developed to control the rehabilitation robot. The experimental setup and evaluation of the robot design, together with the nonlinear model predictive controller, was carried out with healthy users and yielded the intended results. The robotic orthosis along with the NMPC could successfully guide the healthy human subject along the pre-defined trajectory.

Book Description
The concepts represented in this textbook are explored for the first time in assistive and rehabilitation robotics, which is the combination of physical, cognitive, and social human-robot interaction to empower gait rehabilitation and assist human mobility. The aim is to consolidate the methodologies, modules, and technologies implemented in lower-limb exoskeletons, smart walkers, and social robots when human gait assistance and rehabilitation are the primary targets. This book presents the combination of emergent technologies in healthcare applications and robotics science, such as soft robotics, force control, novel sensing methods, brain-computer interfaces, serious games, automatic learning, and motion planning. From the clinical perspective, case studies are presented for testing and evaluating how those robots interact with humans, analyzing acceptance, perception, biomechanics factors, and physiological mechanisms of recovery during the robotic assistance or therapy. Interfacing Humans and Robots for Gait Assistance and Rehabilitation will enable undergraduate and graduate students of biomedical engineering, rehabilitation engineering, robotics, and health sciences to understand the clinical needs, technology, and science of human-robot interaction behind robotic devices for rehabilitation, and the evidence and implications related to the implementation of those devices in actual therapy and daily life applications.

Book Description
This book investigates a biologically inspired method of robot arm control, developed with the objective of synthesising human-like motion dynamically, using nonlinear, robust and adaptive control techniques in practical robot systems. The control method caters to a rising interest in humanoid robots and the need for appropriate control schemes to match these systems. Unlike the classic kinematic schemes used in industrial manipulators, the dynamic approaches proposed here promote human-like motion with better exploitation of the robot’s physical structure. This also benefits human-robot interaction. The control schemes proposed in this book are inspired by a wealth of human-motion literature that indicates the drivers of motion to be dynamic, model-based and optimal. Such considerations lend themselves nicely to achievement via nonlinear control techniques without the necessity for extensive and complex biological models. The operational-space method of robot control forms the basis of many of the techniques investigated in this book. The method includes attractive features such as the decoupling of motion into task and posture components. Various developments are made in each of these elements. Simple cost functions inspired by biomechanical “effort” and “discomfort” generate realistic posture motion. Sliding-mode techniques overcome robustness shortcomings for practical implementation. Arm compliance is achieved via a method of model-free adaptive control that also deals with actuator saturation via anti-windup compensation. A neural-network-centered learning-by-observation scheme generates new task motions, based on motion-capture data recorded from human volunteers. In other parts of the book, motion capture is used to test theories of human movement. All developed controllers are applied to the reaching motion of a humanoid robot arm and are demonstrated to be practically realisable. This book is designed to be of interest to those wishing to achieve dynamics-based human-like robot-arm motion in academic research, advanced study or certain industrial environments. The book provides motivations, extensive reviews, research results and detailed explanations. It is not only suited to practising control engineers, but also applicable for general roboticists who wish to develop control systems expertise in this area.

Book Description
Robotic engineering inspired by biology—biomimetics—has many potential applications: robot snakes can be used for rescue operations in disasters, snake-like endoscopes can be used in medical diagnosis, and artificial muscles can replace damaged muscles to recover the motor functions of human limbs. Conversely, the application of robotics technology to our understanding of biological systems and behaviors—biorobotic modeling and analysis—provides unique research opportunities: robotic manipulation technology with optical tweezers can be used to study the cell mechanics of human red blood cells, a surface electromyography sensing system can help us identify the relation between muscle forces and hand movements, and mathematical models of brain circuitry may help us understand how the cerebellum achieves movement control. Biologically Inspired Robotics contains cutting-edge material—considerably expanded and with additional analysis—from the 2009 IEEE International Conference on Robotics and Biomimetics (ROBIO). These 16 chapters cover both biomimetics and biorobotic modeling/analysis, taking readers through an exploration of biologically inspired robot design and control, micro/nano bio-robotic systems, biological measurement and actuation, and applications of robotics technology to biological problems. Contributors examine a wide range of topics, including: A method for controlling the motion of a robotic snake The design of a bionic fitness cycle inspired by the jaguar The use of autonomous robotic fish to detect pollution A noninvasive brain-activity scanning method using a hybrid sensor A rehabilitation system for recovering motor function in human hands after injury Human-like robotic eye and head movements in human–machine interactions A state-of-the-art resource for graduate students and researchers.
