Sensor networks are increasingly used to control and monitor industrial and manufacturing processes. In this paper, we consider the problem of optimizing a cost function for wireless sensor networks of this kind under energy consumption constraints. We focus, in particular, on the problem of coverage optimization through scheduling. Following existing(More)
The Devices for Assisted Living (DALi) project is a research initiative sponsored by the European Commission under the FP7 programme aiming for the development of a robotic device to assist people with cognitive impairments in navigating complex environments. The project revisits the popular paradigm of the walker enriching it with sensing abilities (to(More)
—This paper presents a position tracking technique based on multisensor data fusion for rollators helping elderly people to move safely in large indoor spaces such as public buildings, shopping malls or airports. The proposed technique has been developed within the FP7 project DALi, and relies on an extended Kalman filter processing data from dead-reckoning(More)
In the FP7 E.C. DALi project, we pursue a mobility aid device – the cWalker – that supports navigation in crowded and unstructured spaces by acquiring sensory information by anticipating the intent of human agents and by deciding the path that minimises the risk of accidents. To achieve its ambitious goals the cWalker relies on a multidisciplinary effort(More)
Models are used in control domains for early validation of system properties, using simulation or formal verification, and for the automatic generation of a software implementation. We propose an approach in which a functional model of the controls is matched to a model of the execution platform through an intermediate mapping model, that represents the(More)
In the last decades, model based methodologies have become the mainstay of research on embedded systems development. The availability of mature computer aided tools and of well-settled industrial practices has promoted the adoption of these methodologies in large companies, which are able to amortize the cost on a large volume of products. On the contrary,(More)
— In this paper, we consider the optimal motion planning problem for an autonomous race car. A competitive autonomous car must acquire environmental and opponent information to compute, in real time, the minimum time collision free path and the low level control to track the chosen path. To cope with those requirements, we first solve the problem for a car(More)
High performance robotics is traditionally considered as an application area reserved to university laboratories and to the research centres of a limited group of company, which can afford high investments in equipments and system engineering. We make the point that this is not necessarily true if an adequate design is used to compensate for the lack of(More)
