L’homme est-il toujours le meilleur robot ?

Le terme de « robot » qui signifie « travail » a été introduit par Karel Tchapek en 1921 dans une pièce intitulée, Les robots universels de Rossum, puis repris par Isaac Asimov dans un de ses romans, I Robot. Depuis la robotique s’est considérablement développée grâce à son utilisation dans l’industrie pour exécuter des tâches répétitives pénibles pour l’homme telles que la soudure par point ou la peinture et aussi grâce à l’identification d’une branche nouvelle de la mécanique avec de multip..

Identification of a First Order Model of Implanted Electrodes on the First SUAW Patient

International audienceImpedance evaluation of implanted electrodes is necessary to ensure that the implant can deliver the specified current, and to survey any failure due to the electrodes. To perform the identification in the implanted hardware, a simple, but sufficiently descriptive model, must be used because of the poor excitation input signal and in order to avoid complex identification algorithms. Data recorded on the first implanted SUAW patient give information on the real impedance of both neural and epimysial electrodes and an opportunity to validate simple first order models

Balance and stabilization capability of paraplegic wheelchair athletes

International audienceThe orientation of paraplegic athletes toward adapted sport activities requires good knowledge of their functional characteristics. Wheelchair locomotion, especially for highly dynamic situations, poses the problem of trunk equilibrium. _c,_1ent and heal sabilization. The study aimed at desiguin g a quantitative method to assess the ability of paraplegics to obtain trunk b .t ;nder dynamic stresses, and to analyze the various balanc. strategies. according to the spinal lesion level of the subjects. High (HPA) and low (LPA) paraplegic athletes were subjected to four series of antero-posterior stresses of increasing intensity, generated by an oscillating platform. By means of a computerized video-based movement analyzer, acceleration in the saggittal plane was measured at four different spinal levels and, for each one, a damping factor was determined. This factor, computed at the head level, appeared to be representative of the subjects' ability to maintain balance. We attempted to differentiate balance strategies in the LPA and HPA groups through analysis of the relative contributions to damping of the thoracic and cervical spinal segments. The first results show an increasing tendency of neck reflex stiffening according to the neurological level
