چکیده
The equivalence between autonomicity and the absence of free variables is a well-known result for linear, shift-invariant and complete behaviors over a field. However, this no longer holds for a behavior that does not satisfy one of those properties. In this paper we consider linear, shift-invariant and complete behaviors over the ring Zpr and study under which conditions such behaviors are autonomous and/or have no free variables.

A new sensor based homing integrated guidance and control law is presented to drive an underactuated autonomous underwater vehicle (AUV) towards a fixed target, in the horizontal plane, using the information provided by an Ultra-Short Base Line (USBL) positioning system. Almost global asymptotic stability (AGAS) is achieved, both in the absence of external disturbances and in the presence of co...

This paper presents a short range wireless network platform based on Bluetooth technology and on a Round Robin scheduling algotithm. The main goal is to provide an application independent platform in order to support a distributed data acquisition and control system used to control a model of a greenhouse. This platform enables the advantages of wireless communications while assuring low weight...

In this paper we propose an approach to handle the cooperative localization of an object by a team of robots. Our technique uses propagation of beliefs to combine information provided by a team of robots so as to support a teammate in critical situations when it can not see an object, is lost or it is equipped with low quality sensors and needs cleaner data. Since teammates are a special case o...

Motivation is a key ingredient for learning: If the learner is motivated, you may hope for some success. If she/he is not, you may as well stop here. Educational robotics has proven to be an excellent tool for motivating students at ages from 8 to 80. This paper describes the use of competitions in order to sustain motivation over a longer period of time, which increases the chances that the le...
