Statistical method can differentiate two targets (Plane and Corner) with higher accuracy, improving on previously reported methods. It achieves this by exploiting identifying echo features: the differential frequency, length, amplitude and time-of-flight (TOF) characteristics of these targets. The features extraction is also studied and the reduction of parameters is obtained with a SBS (Sequential Backward Selection) approach. The results indicate that the amplitude information is more crucial than other features. The study suggests a wider use of statistical methods and amplitude information in sonar-based mobile robotics

The main objective is to give person hours of independence by using a mobile base mounted arm. Because of particular constraints of this field of application the machine is semiautonomous and requires a close human machine co-operation for its control. In order to develop a user oriented machine control it is significant to determine the limits of autonomy of an affordable robot. After a description of the whole assistance system the paper focuses on the localisation problem of the mobile robot in a partly known environment.

The system is a semi autonomous mobile arm manipulator designed keeping in mind specificities due to a close cooperation between human and machine. In order to take into account the diversity of situation three kinds of control modes are proposed to the user. The paper focuses on the evaluation of ARPH system by disabled people in situation close to daily living. Several types of information were obtained concerning use, interface, ergonomics, safety and training. It should be noted that the phase of familiarisation during which the people were free to use the robot with their own way was particularly interesting for the usage foreseen by the designers of the product and the need for physical exchanges with others that the robot by its capacities of displacement and contact makes it possible to recreate...

Du point de vue de la conception, il est pertinent de considérer la personne et le robot d'assistance comme deux éléments appartenant à un système complexe global. La coopération interne entre ces deux entités devient indispensable et permet de mettre en place des solutions innovantes. Ce papier tente de montrer sur l'exemple de la commande d'un bras mobile qu'il est possible de proposer de nouveaux algorithmes en s'appuyant sur les capacités de la personne. Nous avons montré qu'une méthode de résolution de problèmes utilisée en IAD offre une alternative aux modèles mathématiques généralement mis en oeuvre pour commander un robot. Cette approche offre des avantages. Cependant le caractère local de la résolution nécessite la présence d'un niveau supérieur possédant une vision globale du processus et capable de décision. E...

This low cost constraint implies the use of a poor perception system and a low computing power. In such a context, algorithms have to be simple in order to be executed in real time and proof against the weaknesses of the sensing system. The solutions proposed for the localisation are based on the fact that the higher the localisation algorithm speed is the lower the error on the position and on the orientation due to the odometry is.

The challenge is to provide an approach to deal with a dynamic environment in order to provide an adequate service to the person. It’s necessary to take into account constraints, the degree of urgency of the service and the degree of intrusion. The evolution of the degree of intrusion of the system based on the degree of urgency the availability of the different communication devices that constitute the environment are particularly targeted. Through an adaptive approach coalitions adaptations, our multi-agents system ensures answers to various or unforeseen situations. Our coalition protocol was implemented in a real scenario on ambient intelligence context. Objective: A mobile robot is based on the existence of communicating objects networks to decline a set of services and teleservices designed to facilitate the daily life of the person and his entourage at home. Result: The proposed solutions have been implemented on a real system and evaluated in real situations.
