This paper proposes a new multiagent planning approach to coordination synthesis that views distributed agents as discrete-event processes. The connection between discrete-event control synthesis and coordination planning is first established, thereby enabling the exploitation of the vast body of knowledge and associated software synthesis tools from 'The Supervisory control of Discrete-Event Systems' for automatic coordination synthesis of distributed agents. Importantly, these coordinating agents designed collectively generate a behaviour guaranteed not to contradict any specified inter-agent constraint, is nonblocking and optimal. A simple planning methodology is proposed in terms of procedures supported by CTCT, an existing, freely available design tool developed based on the control synthesis framework. A simple example illustrates the use of the CTCT-based methodology to synthesize coordination modules for distributed agents. Discussions in relation to previous work examine the relative significance of the new multiagent planning framework.

A microrobot-based nanohandling station, which is able to handle objects in the micrometer range and below, is introduced. Following a short description of the microrobot's mobile platfonn the station's control system is described. The application of an extended Kohonen network for the low-level pose control of the mobile platform is presented in detail as well as some results achieved.

This paper presents the current work on the development of a tool for remote control of mobile robots. The tool consists of a local controller on the robot side and a user interface for simulation and remote control that connects with the robot through the network. The user interface is implemented as an HTML page with a Java applet for remote control and communication and a virtual environment written in VRML for visualization. This way users have the ability to connect to a dedicated WWW server and download the user interface. This paper describes the concept of the tool design and the developed user interface.

Image de-noising and restoration represent basic problems in image processing with many different applications including engineering, reconstruction of missing data during their transmission and enhancement of biomedicai structures as well. This problem occurs also in filling-in blocks of missing or corrupted data. The paper presents the use of Wavelet transform in this area including its application for image decomposition and rejection of its components at first. The main part of the paper is devoted (i) to algorithms of restoration of missing image blocks by the search of similar structures of a given image in the Wavelet domain space and (ii) to comparison of this approach with iterated Wavelet interpolation and predictive image modelling. Proposed methods are verified for simulated data and then applied for processing of magnetic resonance images.

In this paper a non-linear fuzzy autopilot for ship track-keeping is presented. The proposed autopilot has four inputs (actual and desired heading, rate of change of heading and offset from the desired path) and one output (command rudder angle). The track-keeping problem is decomposed into two subtasks: (i) followthe desired heading, and (ii) bring the ship onto the desired path and keep tracking. Internally, the autopilot consists of two autopilots that fulfil these tasks simultaneously. The proposed control scheme has been verified using a non-linear model of a Mariner-class vessel and steering mechanism under the influence of wave and current disturbances. Results presented show how such a control strategy enables improved tracking performance.
