“…In 1994, researchers of Kanagawa Institute of Technology developed a wearable power assisting suit for nurses to enhance their muscle strength to lift patients and avoid back injuries [15]. The movement of the joints at arms, waist and legs of the suit were sensed by strain sensors to detect the muscle force and actuated by pneumatic rotary actuators with concentric round boxes sliding each other [16,17].…”

Abstract. For over a century, the development of exoskeletons experienced five periods including sprout, exploration, dormancy, accumulation and climax period from a concept in 19 th century to applications in distinctive fields in 21 th century. Recently, exoskeletons are applied in military, civilian and rehabilitation to augment the travel and loading abilities of soldiers, increase an operator's load-handling capabilities, reduce the occurrence of musculoskeletal disorders, and improve the lost functions and quality of life of patients, respectively. Aiming at lessening the strain on physical therapists to train patients with severe or degenerative disabilities, motor cognitive limitation and improving their quality of life, exoskeletons are applied on the field of rehabilitation, mainly on patient training and locomotion. Although great progress has been made in the century long effort to design and implement exoskeletons, many design challenges still remain including powered devices, the comfort of human-machine interface and how to effectively understand the wearer's intensions.

“…In recent years, using robotics technology, many assist devices and systems have been developed. Most of those devices were designed to increase caregivers' or patients' power directly using some wearable/unwearable power-assisting devices [1], [2], [3]. Some other devices can care patient automatically or semiautomatically instead of caregivers [4], [5].…”

In our research center, we have developed a nursing-care assistant robot. This robot can lift up and transfer patient between bed and wheelchair using two human like arms. In this research, in order to generate comfortable liftup motion automatically for this robot, we proposed a new method by reducing patient's load and pain feeling during lifting-up. We developed a musculoskeletal model to estimate muscle force, which shows the load of human body. A stiffness sensor was also developed to measure the softness distribution of human body. Contact human body on soft place can make people feel less pain. In simulation, we estimate human posture and comfortable robot motion by minimizing muscle force and contacting human body on the softest places. In experiments, the measured subjects' postures were compared with the estimated value using the estimated motions. Measured postures were very close to simulation, which shows the effectiveness of proposed method.

“…Many attempts have been made to develop full-body or lower-extremity exoskeleton robots and active prosthetics for walking assistance of able-bodied persons or for the assisted rehabilitation of physically challenged persons [2]- [8]. As well as the increased importance of developing the robot hardware, designing robot controllers that can manage a) the diversity of user motions and b) the interaction among the user, robot, and environment has become crucial.…”

Several studies have been attempted on human walking assistance using exoskeleton robots. To achieve the effective walking assistance with a variety of user motions, the robot behaviors need to be coordinated with both predicted user motions and the environment spatiotemporally. In this paper, we study how movement prediction and temporal synchronization can be beneficial for walking assist exoskeletons using the framework of style-phase adaptive pattern generation [1]. In particular, we empirically investigate the following two issues: i) mutual synchronization between a human subject and a humanoid model through style-phase adaptation, and ii) using style-phase adaptation for walking assistance. We developed two experimental platforms for the two investigations and conducted subjective experiments. The experimental results suggest that visual feedback of the state of the humanoid model can enhance the mutual synchronization through style-phase adaptation, and the estimated style and phase can be useful to assist walking movement of the human subject.
