The next generation of tools for rehabilitation robotics requires advanced human-robot interfaces able to activate the device as soon as patient’s motion intention is raised. This paper investigated the suitability of Support Vector Machine (SVM) classifiers for identification of locomotion intentions from surface electromyography (sEMG) data. A phase-dependent approach, based on foot contact and foot push off events, was employed in order to contextualize muscle activation signals. Good accuracy is demonstrated on experimental data from three healthy subjects. Classification has also been tested for different subsets of EMG features and muscles, aiming to identify a minimal setup required for the control of an EMG-based exoskeleton for rehabilitation purposes.

The will of humans with physical disabilities to move has found realization through the development of powered roboticexoskeleton. In this study, an energy-efficient gait pattern and swing trajectory of the powered robotic exoskeleton was proposed through function distribution analysis and the dynamic-manipulability ellipsoid (DME). To verify its feasibility and the effect of the proposed optimal gait pattern from the point view of the integrated system (human and exoskeleton), simulations were performed in the cases of walking on level ground and stair ascent/descent. Experiments such as on the metabolic cost of the human body with or without the assistance of the exoskeleton were conducted, and the power consumption of the exoskeleton was assessed, with the aim of improving the efficiency of the integrated system.

A garment for stimulation of a wearer’s sensory motor system. The garment includes a main body portion that includes an anterior portion and a posterior portion and at least one sensory motor stimulation member associated with the main body portion. The garment is configured to be worn over at least a portion of the wearer’s torso and is form-fitting when worn by the wearer. The at least one sensory motor stimulation member contacts the wearer’s skin when the garment is worn. The garment is fabricated from an elastomeric material that causes the at least one sensory motor stimulation member to stimulate the cutaneous nerve receptors in the wearer’s skin contacted by the at least one sensory motor stimulation member.

Disclosed herein is a control system for an exoskeleton haptic device, having: a frame structure, to be coupled to the body of a subject; actuators, carried by the frame structure and operable to cause movement of a number of joints of the body; and sensors, coupled to the body to detect first signals indicative of an intention of movement of the subject. The control system is provided with: a feedback stage, controlling a position of the joints based on a reference position; a feedforward stage, controlling a compliance presented by the exoskeleton haptic device to the subject based on the detected first signals; and a combining block, combining outputs from the feedback stage and feedforward stage in order to generate a driving signal for the actuators, thereby imposing a controlled position to the joints. This primary control action may also be integrated with a posture equilibrium control, for controlling postural equilibrium of the subject during the movement.

Компания Sakakibara Kikai решила выпустить экзоскелет для детей. Высота робота – всего 1 метр 60 сантиметр, весит он около 180 килограмм. Интерфейс экзоскелета упрощен специально для детей, чтобы ребенок не запутался в управлении и не попал в беду.
