The objective of this project is to develop a new kind of visual sensor: complex enough to sense and describe the visual world it observes - yet enjoys the characteristics of simple (e.g. temperature) sensors: ultra-low power consumption, easy connect ability, and a small, unobtrusive form-factor. The proposed vision system is based on a custom CMOS ultra low-power vision sensor, partially embedding a reliable algorithm for people detection and monitoring in the analog stage of the pixel; a low power sensor interface allowing the sensor to live for at least 5 months- with a minimum energy-budget, powered with a tiny battery or a super capacitor, which can be recharged by a 1 cm2 solar-cell; a high-level computing platform which is turned on only when necessary, triggered by the sensor as soon as it detects a potential alert situation.
This project is aimed at the integration among the individual, collective and communication controls of a multi robot system to ensure full operation capabilities. The chosen test case will be based on an underwater swarm of simple autonomous mobile communication nodes with sensing capabilities for environmental monitoring. The global control architecture will come from the study of an equilibrium among three basic issues: the human furnished goals, the need for reliable inter-nodal communications (that affects the geometrical configuration), the local planning and the priorities of the single individual. The equilibrium will change depending on the assigned tasks, the survival risk associated to the operation of each robot and the risk associated to the loss of connection with the multi body system as a whole. In order to minimize the computational effort of the single individual a neural network approach will be studied for the management of the supervising equilibrium.
