“…The proposed robotic system with normalized force field possesses two major advantages. One is the independent threedimensional workspace for each human limb compared with the state-of-the-art technologies [12,13,15,16,25,30]. This can better guarantee the workspace of gADLs where coordination of both limbs with three dimensions is commonly required, such as eating steak with a knife and fork.…”

“…Guo, et al [29] implemented passive mirroring on a single-arm robot in a master-slave configuration using an external haptic device. Xu, et al [30] developed a pneumatic robotic system for bilateral upper limb training with adjustable resistances, but only allowing for linear movements. It should be noted that while some existing robotic systems have multiple degrees of freedom, few have been implemented with force field control between bilateral robotic handles for ADL rendering, as defined in Fig.…”

Individuals with physical limb disabilities are often restricted to perform activities of daily life (ADLs). While efficacy of bilateral training has been demonstrated in improving physical coordination of human limbs, few robots have been developed in simulating people's ADLs integrated with task-specific force field control. This study sought to develop a bilateral robot for better task rendering of general ADLs (gADLs), where gADL-consistent workspace is achieved by setting linear motors in series, and haptic rendering of multiple bimanual tasks (coupled, uncoupled and semi-coupled) is enabled by regulating force fields between robotic handles.Experiments were conducted with human users, and our results present a viable method of a single robotic system in simulating multiple physically bimanual tasks. In future, the proposed robotic system is expected to be serving as a coordination training device, and its clinical efficacy will be also investigated.

“…To attain a particular level of enforcement, there are many approaches: to change the rigidity of the transmission systems and the physical connections connecting the actuator to the end effector, as well as the energy storage capacity of the transmission/linkage pair. Most of the prototypes use pneumatic actuators due to their lightweight and higher torque yielding capacity. Xu et al 3 used a pneumatic system in their prototype. In this system, the bilateral robotic system’s variable resistance can be modified depending on the severity of the patient's impairment.…”

An exoskeleton is an external cast which can be used to maneuver, protect or even provide a greater magnitude of strength to the upper limb allowing for heightened efficiency and performance. The limb may be weakened due to so many diseases or reasons such as paralysis, stroke, muscular atrophy, and different kinds of injuries. Numerous designs and manufactured prototypes of pneumatic exoskeletons have been reviewed—their pros and cons weighed against each other. This paper covers the fundamental concepts of various prototypes that have been designed and developed over the years. The best mechanism has been highlighted, although the design of a fully efficient exoskeleton comes with its set of drawbacks. Types of energy used for the driver unit, types of actuators, materials used, design concepts, and overall weight and manufacturing cost of every prototype has been contrasted with the others to conclude what an ideal exoskeleton for rehabilitation purposes must look like and the principles and features of the prototype must be decided upon by keeping aesthetics and ergonomics in mind.

In view of the urgent need for intelligent rehabilitation equipment for some disabled people, an intelligent, upper limb rehabilitation training robot is designed by applying the theories of artificial intelligence, information, control, human-machine engineering, and more. A new robot structure is proposed that combines the use of a flexible rope with an exoskeleton. By introducing environmentally intelligent ergonomics, combined with virtual reality, multi-channel information fusion interaction technology and big-data analysis, a collaborative, efficient, and intelligent remote rehabilitation system based on a human’s natural response and other related big-data information is constructed. For the multi-degree of the freedom robot system, optimal adaptive robust control design is introduced based on Udwdia-Kalaba theory and fuzzy set theory. The new equipment will help doctors and medical institutions to optimize both rehabilitation programs and their management, so that patients are more comfortable, safer, and more active in their rehabilitation training in order to obtain better rehabilitation results.
