Studies on human visual perception are described. The visual perception is mathematically modelled as a probabilistic process obtaining and interpreting visual information from an environment. By means of this model some other vision related concepts, such as visual attention and visual openness, are also mathematically defined. The theoretical considerations are implemented in three applications, namely scene description by perception, visual openness measurement for design, and perceptual robotics.

Session 1 includes 109 papers selected from 2011 3rdinternational Asia conference on informatics in control, automation and robotics (CAR 2011), held on December 24-25, 2011, Shenzhen, China. This session will act as an international forum for researchers and practitioners interested in the advances in and applications of Intelligent control Systems. It is an opportunity to present and observe the latest research, results, and ideas in these areas. Intelligent control is a rapidly developing, complex, and challenging field of increasing practical importance and still greater potential. Its applications have a solid core in robotics and mechatronics but branch out into areas as diverse as process control, automotive industry, medical equipment, renewable energy and air conditioning. So, this session will aim to strengthen relationships between industry, research laboratories and universities. All papers published in session 1 will be peer evaluated by at least two conference reviewers. Acceptance will be based primarily on originality and contribution.

Networked robotics is an area that straddles robotics and network technology. A robot system controlled via the WWW exploits the Internet network and hence is one realisation of networked robotics. A set of field robots that exploit wireless networks to share and distribute tasks might also be considered an exemplar of networked robotics. But isn't this just an exemplar of distributed robotics? And if so, what does networked robotics bring to the 'robotics' table? These are questions and issues addressed in this paper. The paper will propose that networks are at once both enabling and constraining to robotics. They enlarge the scope of the robotics discipline yet introduce challenges that must be overcome if that potential is to be fully realized. In short, when the network becomes a design issue - normally when performance of the system is at a premium - networked robotics is at play.

This paper proposes a Particle-Filter approach and a set of motion strategies to cooperatively localize a team of three robots. The allocated mission consists on the path following of a closed trajectory and obstacle avoidance in isolated and unstructured scenarios. The localization methodology required for the correct path following relies on distance and orientation measurements among the robots and the robots and a fixed active beacon. Simulation results are presented.

Ultra-high precIsion machining is proposed by externally actuating the work piece in linear motions in the X-Y plane and linear motion in the Z-axis. To solve the problems in the machining process such as nonlinearity and low repeatability positioning accuracy of machining tools in a larger scale, a novel platform for cutting tools in micro machining based on electrostatic linear micromotors and piezoelectric stack actuator system is presented.

In the grass-roots units, the speed of equipment identification directly affect the accuracy and timeliness of equipment maintenance. In this paper, several now-existing methods of identification are aggregated and combed. The problems in the supply-level application of the spare parts are found, and a method for identifying the equipment entities called "Unlabeled Identification Technology of Equipment Based on Machine Vision" is proposed. In addition, the advantages of the method, which is very beneficial to the promotion of battlefield support ability, are obtained by comparing the differences between the old and new methods.

Tracking multiple targets is a great challenge for most tracking algorithms, since these algorithms tend to loose some of the targets when they get close to each other. Hence, several algorithms like the MHT, the JPDAF and the PMHT have been developed for this task. However, these algorithms are specialized on punctiform targets, whereas in mobile robotics one has to deal with extended targets. Therefore, in this paper an algorithm is proposed that can solve this problem. It uses the Viterbi algorithm and some geometrical characteristics of the problem. The proposed algorithm was tested with real world data.

Aiming at the mainlobe jamming problem of monopulse radar, based on the method of dual polarization decoupling estimation, a design scheme of angle measurement system for dual polarization monopulse radar in mainlobe jamming is proposed. The monopulse radar is changed to the dual polarization receiving mode. Combined with the goniometry algorithm, the coupling error of the jamming on the target angle estimation can be eliminated and the target identification and tracking can be completed effectively.

When the distance information is used for localization, due to the influence of system equipment and environmental disturbance, the distance measured will introduce error, which affects the localization accuracy. Based on the multi-sensor network technology, the traditional range localization method is improved in this paper. A rapid localization method of radiation sources used for multi-sensor networks is provided, which can accomplish the target location of the radiation source effectively and improve the localization accuracy.

"The URC (Ubiquitous Robotic Companion, Server computer-based networked robotic)" systems exploiting Internet-related technologies and Server computer require effective techniques for timely delivery of requested data to remote clients. In these systems, there is a need to process real-time data in server computer from/to robots and clients during system operation. In this paper, we describe and evaluate ASR, TTS server systems in the context of a real-time environment for the URC applications. Experimental results show that the server-based ASR, TTS support timely delivery of data to a potentially large number of robots during system operation.
