In present time, the need for flexibility in different organizational structures, impose top equipment for infrastructure. These mobile platforms are equipped with many electrical appliances and the needs for power limits the consumption of these platforms or impose the rinse of infrastructure with power generators. In this paper we present a sun tracking system mounted on a mobile platform and based on two local intelligent servo drives connected on a CAN network to a motion controller which has implemented a solar position algorithm. The motion controller determines the position of the sun on the site, and then, coordinates the two drives in order to correctly position the photovoltaic panel. [ABSTRACT FROM AUTHOR]

Due to the quick evolution of manufacturing processes, the demand for more flexible automation systems is on the rise. To answer to these requirements, distributed control architecture based on intelligent drives and CAN networks tends more and more to replace the traditional solutions. CAN was designed and applied in car networking in order to reduce the complexity of the related wiring harnesses. The traditional CAN application technique must be changed in order to achieve the real-time communication constraints of a distributed control system. In this paper is designed a special purpose scheduler for CAN, which ensures a message transmission time smaller than a value estimated from the design stage. Furthermore, the designed architecture has a message recognition mechanism. [ABSTRACT FROM AUTHOR]

In semiautonomous mobile sensor networks, since human operators may be involved in the control loop, particular improper actions may cause accidents and result in catastrophes. For such systems, this paper proposes a command filtering framework to accept or reject the human-issued commands so that undesirable executions are never performed. In the present approach, Petri nets are used to model the operated behaviors and to synthesize the command filters for supervision. Also the command filter could be implemented using agent technology by associating a filtering agent for each robot. It is believed that the technique presented in this paper could be further applied to large-scale wireless mobile sensor networks. [ABSTRACT FROM AUTHOR]

Due to the quick evolution of manufacturing processes, the demand for more flexible automation systems is on the rise. To answer these requirements, distributed motion control architecture based on intelligent drives tends more and more to replace the traditional solutions. This paper presents a local intelligent drive that controls the position of an articulated arm robot. The driver receives the spatial coordinates of the gripper, via a CAN network, and synchronise the motors to move the arm to the desired position. [ABSTRACT FROM AUTHOR]

Due to the quick evolution of manufacturing processes, the demand for more flexible automation systems is on the rise. To answer these requirements, distributed motion control architecture based on intelligent drives tends more and more to replace the traditional solutions. The benefits of a distributed motion control architecture are presented in the paper. Intelligent servo drivers suitable for distributed motion control architecture must provide fieldbus communication facilities and execute high level axis control tasks. The fieldbus profile design and the motion control task distribution is the key point to build a high performance motion control system. [ABSTRACT FROM AUTHOR]
