“…Mechanisms such as the EXO-UL7 ( Figure 1c) and the NX-A2 ( Figure 1f) are used during rehabilitation, but the weight and size of the actuators in these systems actually hinders their portability [22]. Also, there are full body exoskeletons such as [23].…”

Personal safety is a critical aspect of daily life, but also in the military. Active soldiers often have to carry heavy gear during missions, which puts pressure on their backs. Therefore, the military must come up with new technologies that allow both protection and movement. In this paper, it is explaining the development of an armored upper limb exoskeleton with three degrees of freedom. To ensure portability, it is used battery-fed DC actuators. The system was encased in a metal matrix that doubles up as a protective plate. The exoskeleton, the control system, the actuators, and the plate are integrated so that they offer protection while supporting the flexion and extension of the upper limb.

“…It is also noteworthy to include research done by Kanagawa Institute of Technology to open the interest in a different application area. Their device, 'Power Assist Suit', was designed to assist nurses and caregivers when handling and supporting patients, to avoid back injuries [22]. They claimed that this device can support a patient of 85 kg, without enforcing a burden on the wearer [20].…”

The prevalence of work-related musculoskeletal disorders is a common issue in many occupations involving manual handling activities. In order to aid manual workers in reducing the burden on the musculoskeletal system, various wearable robotic technologies have been developed over the years. An increase in research work on wearable technologies has been observed, particularly in the last decade. In that context, this article presents a comprehensive review and a bibliometric analysis of the recorded occupational exoskeletons for manual handling since 2010. The review is aimed at identifying the paradigm shifts of research in the recent past and associating the trends pertaining to the applications, mechanisms, and control systems in the development of wearable devices for manual handling. The scope of the review limits itself to active and passive exoskeletons designed to support the upper extremity, lower extremity, and spine for performing load lifting, load carrying, or static holding. The analysis of the results revealed the emerging trends with the aim of providing researchers with areas for improvement and suggestions for different clusters of devices.

“…Many assistive devices have been developed, e.g. power assist suit (Tanaka et al, 2006), walking assist machine (Ishii et al,2006), and so on. However, these devices assist humans based on pre-defined force and provide the same assistance regardless of changes in human motion.…”

Physical training enables us to recover from disability in rehabilitation or to acquire motion skill. So far, many devices that assist human's motion such as power assist suit have been developed. However, these devices do not consider human's proficiency level or recovery degree, therefore some adjustments of the device i.e. how much the device generates its force, will be required according to the human's proficiency level. In this paper, focusing on stabilization of an inverted pendulum, we propose a varying controller design method that changes its contribution for stabilization based on human's proficiency level. The controller is designed based on Model Predictive Control (MPC) for fast on-line calculation. Human's proficiency level is calculated from convergence level of the inverted pendulum system. The convergence level is obtained by a norm of state variables which is coordinate-transformed so that its norm decreases monotonically according to convergence. Based on human's proficiency level, the controller is designed to change its contribution. Experimental results show the degree of controller contribution is decreased for high skilled subjects and increased for low skilled subjects.
