Abstract . Exoskeleton robots are developing rapidly in the field of industrial manufacturing and medical rehabilitation as an intelligent wearable power assist device, which can reduce lifting burden muscle fatigue. Existing upper limb passive exoskeleton still need to be improved for human-machine integration. In this paper, by establishing a human kinematic model lumbar spine motion model, i...

This contribution aims at presenting the first clinical evaluation trials of a Series-Elastic-Actuator based exoskeleton for post-stroke elbow rehabilitation, NEUROExos, from the BioRobotics Institute of Scuola Superiore Sant'Anna.

Beetle forewings are modified into hardened structures called elytra. A recent study indicates that the evolution of elytra involved co-opting genes for exoskeleton formation into the wing development gene network of beetles on at least three separate occasions.

This paper proposes a new concise mathematical model of gear transmission dynamics with asymmetric load-dependent friction. It is built only upon the rigid-contact mechanics and Coulomb friction law, but provides theoretical perspective on dynamic static characteristics transmissions. The presented form differential–algebraic inclusion (DAI) characterized by some parameters, including input-sid...

This is a paper about wearable exoskeleton that addresses the lack of assistive devices for people with walking difficulties. The research revolves around major problem in which inpatient suffer their dependency on caretaker basic tasks such as toiletries and fetching water or food even cores themselves. People disabilities from many social mental pressures due to exclusion society just being d...

The exoskeleton or cuticle of arthropods is an important feature that contributes to their great success in colonising numerous habitats on earth. It has numerous functions among which to provide protection against parasites. Whereas often regarded as a simple physical barrier to the outside world, the immune protection of the cuticle is slightly more complex than that. Here, we provide an over...

Among the potential biological signals for human-machine interactions (brain, nerve, and muscle signals), electromyography (EMG) widely used in clinical setting can be obtained non-invasively as motor commands to control movements. The aim of this study was to develop a model for continuous and simultaneous decoding of multi-joint dynamic arm movements based on multi-channel surface EMG signals...

In this study, surface electromyography (EMG) signals of the Gastrocnemius, Tibialis anterior and Soleus muscles were recorded on various subject during their daily life activities such as walking and stair ascent and decent. The lowerlimb muscle activities have been studied to enable power-assist robotic systems to estimate human lower-limb muscle activities based on muscle electromyographic (...

A pneumatic exoskeleton intended to decrease the muscle activity of the knee extensors during walking on a negative slope is presented. The device consists of an air spring that can be engaged and disengaged via a solenoid valve. When engaged, the air spring resists knee flexion. A preliminary evaluation of the device was conducted with a single healthy subject. During testing, the EMG activity...
