With the increase in aging population, demand for healthcare devices has increased. Among many experience joint pain, muscle weakness, or poor balance. Without external help, such persons may have difficulty walking, fall easily, quality of life. To provide this category population with opportunity to exercise and walk safely take care themselves daily activities, a stepper motor-powered walking assistive device is proposed built. The enables users different heights suitable gaits; assists...

The number of patients suffering from colorectal cancer (CRC) has been increasing. CRC is known to be curable if detected and treated early. Colonoscopy currently one the best screening methods for because it can observe treat disorders in large intestine. However, operating colonoscope technically demanding doctors insertion instrument into intestine requires considerable training skill. To address this issue, we propose a novel self-propelled robot with flexible paddles intestinal tract....

As the population ages, number of elderly people suffering from systemic diseases such as stroke increases. To address this problem, various wearable walking assistive robots have been developed to promote physical exercise for prevention. Wearable shown ability improve human mobility. However, most these are heavy, bulky, and impractical. In study, we a compact ankle robot users exercise. By informing user correct motion timing, can guide achieve healthy gait by only assisting their joint....

Owing to aging populations, the number of elderly people with limb dysfunction affecting their daily lives will continue increase. These populations have a great need for rehabilitation training restore functions. However, current numbers hospitals and doctors are limited. Moreover, often cannot go hospital owing external conditions (e.g., impacts COVID-19). Thus, an urgent exists telerehabilitation system allowing patients at home. The purpose this study is develop easy-to-use target users...

Gastrointestinal cancer, when detected early, is treated by accessing the lesion through natural orifice using flexible endoscopes. However, limited degree-of-freedom (DOF) of conventional treatment devices and narrow surgical view endoscope demand advanced techniques. In contrast, multi-DOF forceps systems are an excellent alternative; however, these often involve high fabrication costs because they require a large number micro-parts. To solve this problem, we designed compact endoluminal...

This paper proposes a three-layer elastic cloth fabric mechanism for an assistive suit with adjustable structure (based on two-layer non-adjustable structure) to achieve different force profiles. increases the lower-back muscle group and alleviates undesired pre-tension that acts user when rubber belt located back is pulled provide higher force. With lower pre-tension, users would not encounter body fatigue as rapidly in past. The feature enables gradually high level over short distance...

With its low birthrate, Japan currently faces an aging issue. As the senior population gradually increases, applying moderate daily exercise has been widely accepted as a key to ease incidence of life-related diseases, such cerebrovascular disease that leads severe aftermath by causing unhealthy gait posture. An already productized active assistive device named RE-Gait® uses motor and pressure sensors detect force varying from forefoot heel in walking, thereby aiding both plantarflexion...

Workers in factories, construction sites, and farms are often exposed to the risk of physical disability injury. Particularly, lower back shoulders require assistance, as injuries can make it difficult continue working. While social concern about is high preventive measures taken, lesser attention paid shoulders, resulting inadequate assistance prevention mechanisms. Therefore, wearable, low-cost, lightweight upper limb assistive devices that be used multiple scenarios desired by workers. In...

Abstract Walking disorders are a major challenge for people with neuromuscular or musculoskeletal impairments, resulting in reduced mobility and quality of life. This paper addresses an approach to design comprehensive mechanical walking assist that facilitates foot flexion extension the by applying force at ankle, while adjusting motion posture healthy pattern. The apparatus uses offset slider crank mechanism lift complete dorsiflexion, four-bar linkage plantarflexion using action-reaction...

As the population ages, number of elderly with systemic diseases like stroke increases. In order to avoid strokes, various wearable walking assistance robots have been developed. However, most them are bulky, heavy, and poorly practical. For users in this study, we developed a compact ankle assistive robot promote exercise. The can help user establish healthy gait by guiding proper motion timing while just supporting joint. To assist users, offers faster-than-ankle movements. With graphical...

With the increasingly serious aging situation, more and elderly people are physically disabled. In addition, current rehabilitation resources have problems of shortage uneven distribution, coupled with impact COVID-19 in early 2019, most patients been greatly restricted from going to center for training. To solve these problems, we propose a "Kinect-based 3D Human Motion Acquisition Evaluation System Remote Rehabilitation Exercise" which uses Kinect3 camera obtain human motion an error rate...

In response to the shortage, uneven distribution, and high cost of rehabilitation resources in context COVID-19 pandemic, we developed a low-cost, easy-to-use remote system that allows patients perform training receive real-time guidance from doctors at home. The proposed uses Azure Kinect capture motions with an error just 3% compared professional motion systems. addition, provides automatic evaluation function training, including angles trajectories. After acquiring user’s 3D motions,...

Incidence rate of colon cancer is the highest among all cancers in Japan while still being on an upward trend. It generally known that diagnosed its early stage, permanently curable by a minimally invasive manner. The first choice diagnosis for colonoscopy inspection requires great skill, because manipulation endoscope surrounded layer soft intestinal tissues highly cumbersome (e. g. large intestines only stretches and tip does not advance even proximal end pushed hard inspector). In order...

This paper proposes a new 3-layer elastic cloth actuation mechanism in assistive suit with adjustable structure, based on 2-layer non-adjustable to increase force lower back muscle group and reduce pre-tension when user pulls the rubber belt located receive higher force. The pretension acted will result faster body fatigue. An experiment involving measurement of activities is implemented evaluate change comparing current model nonadjustable prototype. experimental results show that structure...

We developed motor-less and small type of a walking assistive device. Most previous devices were motored type. However, when the motor is used, computer buttery must be equipped, then it makes heavy weight expensive. On other hand, some are mainly for plantarflexion assistance used by able body people. To address this problem, we utilized spring rachet mechanism, equipped not only but also dorsiflexion in one By using device, had an experiment to measure trajectory angle variation ankle...

Early detection and treatment of intraluminal diseases enable minimally invasive surgery can lead to a high cure rate. Advanced devices with multiple degrees freedom (DOFs) make narrow procedures easier safer. In previous study, we developed multi-DOF compliant endoluminal forceps tendon-sheath mechanism. The maximum bending stress this design was reduced by changing the thickness hinge in each segment, achieved wide range motion. However, its deformed shapes non-constant curvature, due...

In recent years, with the development of robotic technology, prosthetic hands sophisticated functions have been actively researched. On other hands, in terms size, number parts, and customization, low-cost, functional pediatric hand compliant wrist joint hasn’t developed yet. this study, we a 2-DOF for using mechanism, constructed its design methodology, conducted an evaluation experiment prototype. The proposed structure enables circular motion by combining four movements: flexion,...
