This paper presents a new compact and portable 3D camera for space applications. The system is based on a very compact laser line profiler coupled to a 6-DOF positioning device. An advanced prototype of the system is described and scanning results are presented. Future works related to the development of this technology are also discussed.

A humanoid robot "H6" is developed as a platform for the research on perception-action coupling in intelligent behaviour of humanoid type robots. The H6 has the features as follows: 1) body which has enough DOFs and each joint has enough torque for full body motion. 2) PC/AT compatible high-performance on-board computer which is controlled by RT-linux so that from low-level to high-level control is achieved simultaneously.3) self-contained and connected to a network via radio ethernet.4) Dynamic walking trajectory generation, motion planning and 3D vision functions are available. The H6 is expected to be a common test-bed in experiment and discussion for various aspects of intelligent humanoid robotics.

In this paper, rue present a method for automatically creating a 3D model of a scene from a set of range images obtained from unknown viewpoints. Existing 3D modeling approaches require manual interaction or rely on mechanical methods to estimate the viewpoints. Given a set of range images (views), we use a surface matching system to exhaustively register all pairs of views. The results are verified for consistency, but some incorrect matches may be locally undetectable and correct matches may be missed. We then construct a consistent model from these potentially faulty matches using a global consistency criterion to eliminate incorrect, but locally consistent, matches. The procedure is demonstrated through an application, called hand-held modeling, in which a 3D model is automatically created by scanning an object held in a persons hand.

According to the business literature, one can classify a social organization relying on a set of well-known structural features. Depending on the values taken by each of these features, one can conclude whether the type of a specific organization is functional, divisional, hybrid, matrix-like, or process-oriented. The organization type has strong influence upon the way business processes are executed. The workflow technology, on the other hand, aims at supporting the automation of the organization processes. However, most of today's workflow modeling techniques does not consider those structural features in order to assist designers during the modeling process. The present paper discusses the possibility of using the knowledge of the organizational structure to support the workflow modeling process.

The new economy is the result of the information revolution that promotes the emergence of efficient, ubiquitous and virtual-based business models. It is a common belief that the Extended Enterprise (EE) model has the potential to be a competitive advantage, particularly nowadays when the globalisation of trade has increased the number of competitors. Nevertheless, it is necessary to consider the EE as another business model, which has not yet overcome classic problems, such as the management of risk. In this paper we examine the notion of risk, its impact on EE functions and propose a framework for its control.

This paper presents the application of an image registration method for a mobile manipulator. The robot is used for scanning natural terrain and detecting metal objects hidden beneath the terrain surface (e.g., landmines) using a metal detector. The range image may be interpreted for visual servoing, map building and path planning, or object recognition. In this work, the image is used to build a terrain map for obstacle free path planning. Because the working area of the robot is extremely dynamic (i.e., not only the robot travels but also the environment is also subject to change) an active range sensing method is selected to provide the range image. The range values are acquired using a laser range finder with a rotating mirror for scanning so that sensor fusion in the form of collecting sensor readings over an extended period of time is required. In addition, range readings of two ultrasonic range finders are fused at signal level to tackle both sensor imperfection and environmental illumination that induce uncertainty at the system. In this paper, we explain the use of a real-time programming platform that executes an on-line map-building process in parallel for robot manipulation and control.
