In the present work, we aim to manage a set of mobile robots working in a same workspace to survey sites in this workspace. The sites are marked by artificial beacons. Hence we handle a multi-robot system for surveying. Here in we deal with a single mobile robot as a leader. The rest of mobile robots of the system is going to pursue it. We organize the mobile robots of the studied system in a wireless network. It will be architecture as a client/server model. And the appearance of new site to survey imposes a new constraint to the navigation plan. So that the mobile robots that acts as leader must hold in account this new site. As consequence, it processes to give a new itinerary.

In this correspondence paper, we develop a teleoperated robotic 3-D mapping (TeRoM) system which enables efficient human-guided mapping of remote environments for realistic rendering and visualization. First, the hardware design of the TeRoM system is proposed which is based on a Pioneer mobile robot platform and a rotating RGB-D camera. A client/server architecture is developed to allow the data to be processed in a remote server, which makes it possible to implement 3-D mapping on robots with limited resources. Second, a 3-D map is created in real-time while an operator controls the robot and the pan-tilt unit remotely using a joystick. Then the map is converted into a mesh using the marching cubes algorithm and optimized to reduce the data volume. Finally the mesh is imported and rendered in a 3-D rendering engine for interactive and intuitive display. We evaluate the performance of the TeRoM system in terms of accuracy, processing speed, reliability, and manipulability.

With rapid advances in mobile computing, multi-core processors and expanded memory resources are being made available in new mobile devices. This trend will allow a wider range of existing applications to be migrated to mobile devices, for example, running desktop applications in IA-32 (x86) binaries on ARM-based mobile devices transparently using dynamic binary translation (DBT). However, the overall performance could significantly affect the energy consumption of the mobile devices because it is directly linked to the number of instructions executed and the overall execution time of the translated code. Hence, even though the capability of today's mobile devices will continue to grow, the concern over translation efficiency and energy consumption will put more constraints on a DBT for mobile devices, in particular, for thin mobile clients than that for severs. With increasing network accessibility and bandwidth in various environments, it makes many network servers highly accessible to thin mobile clients. Those network servers are usually equipped with a substantial amount of resources. This provides an opportunity for DBT on thin clients to leverage such powerful servers. However, designing such a DBT for a client/server environment requires many critical considerations. In this work, we looked at those design issues and developed a distributed DBT system based on a client/server model. It consists of two dynamic binary translators. An aggressive dynamic binary translator/optimizer on the server to service the translation/optimization requests from thin clients, and a thin DBT on each thin client to perform lightweight binary translation and basic emulation functions for its own. With such a two-translator client/server approach, we successfully off-load the DBT overhead of the thin client to the server and achieve a significant performance improvement over the non-client/server model. Experimental results show that the DBT of the client/server model could achie

The overall system that has been implemented involves a web site which introduces the study and applications of robotics. The web site also acts as a platform to program and control the Gryphon robot found at the Faculty of Engineering, University of Mauritius. The system is based on the client/server model, with a suitable front-end for viewing and interactive sessions with web users and a back-end relational database for storing and retrieving relevant information at the server side. This paper describes the development of a web-based interface for undergraduate students to learn the basics of robotics. The advantage of this interface is that the students can study robotics, write their programs and run the robot remotely at any time and this flexible learning approach definitely contributes to distance education and e-learning through the World Wide Web.
