Development of a low-cost mobile mapping system: A South American experience

This paper presents the prototype of a low-cost terrestrial mobile mapping system (MMS) composed of a van, two digital video cameras, two GPS receivers, a notebook computer, and a sound frame synchronisation system. The imaging sensors are mounted as a stereo video camera on top of the vehicle together with the GPS antennae. The GPS receivers and the notebook computer are configured to record data referred to the vehicle position at a planned time interval. This position is subsequently transferred to the road images. This set of equipment and methods provide the opportunity to merge distinct techniques to make topographic maps and also to build georeferenced road image databases. Both vector maps and raster image databases, when integrated appropriately, can give spatial researchers and engineers a new technique whose application may realise better planning and analysis related to the road environment. The experimental results proved that the MMS developed at the São Paulo State University is an effective approach to inspecting road pavements, to map road marks and traffic signs, electric power poles, telephone booths, drain pipes, and many other applications important to people's safety and welfare. A small number of wad images have already been captured by the prototype as a consequence of its application in distinct projects. An efficient organisation of those images and the prompt access to them justify the need for building a georeferenced image database. By expanding it, both at the hardware and software levels, it is possible for engineers to analyse the entire road environment on their office computers.

Conception of wheeled mobile robots with reconfigurable control using integrate prototyping

With the fast innovation of the hardware and software technologies using rapid prototyping devices, with application in the robotics and automation, more and more it becomes necessary the development of applications based on methodologies that facilitate future modifications, updates and enhancements in the original projected system. This paper presents a conception of mobile robots using rapid prototyping, distributing the several control actions in growing levels of complexity and using resources of reconfigurable computing proposal oriented to embed systems implementation. Software and the hardware are structuralized in independents blocks, with connection through common bus. The study and applications of new structures control that permits good performance in relation to the parameter variations. This kind of controller can be tested on different platform representing the wheeled mobile robots using reprogrammable logic components (FPGA). © 2006 IEEE.

Virtual simulator for mobile robots navigation systems

This paper presents the virtual environment implementation for project simulation and conception of supervision and control systems for mobile robots, that are capable to operate and adapting in different environments and conditions. This virtual system has as purpose to facilitate the development of embedded architecture systems, emphasizing the implementation of tools that allow the simulation of the kinematic conditions, dynamic and control, with real time monitoring of all important system points. For this, an open control architecture is proposal, integrating the two main techniques of robotic control implementation in the hardware level: systems microprocessors and reconfigurable hardware devices. The implemented simulator system is composed of a trajectory generating module, a kinematic and dynamic simulator module and of a analysis module of results and errors. All the kinematic and dynamic results shown during the simulation can be evaluated and visualized in graphs and tables formats, in the results analysis module, allowing an improvement in the system, minimizing the errors with the necessary adjustments optimization. For controller implementation in the embedded system, it uses the rapid prototyping, that is the technology that allows, in set with the virtual simulation environment, the development of a controller project for mobile robots. The validation and tests had been accomplish with nonholonomics mobile robots models with diferencial transmission. © 2008 IEEE.

Uma leitura de 26 poetas hoje / A reading of 26 poetas hoje

Este trabalho procura identificar selecionadas produções poéticas da antologia 26 Poetas Hoje as faces da resistência indicada por Alfredo Bosi no ensaio “Poesia Resistência”. Do “grito de alarme” pessoal de poetas pertencentes a gerações diferentes, emerge uma poesia espontânea, autêntica e, sobretudo, resistente, como produto da renovação da expressão poética, impregnado de afetividades e de intimismo e que incorporou o coloquial e os recursos da grande poesia brasileira desde 22. This reading presents a sample from this anthology and tries to identify in it the faces of resistance indicated by Alfredo Bosi in his essay: “ Poesia Resistência”. In the several manners the poets of different generations chose for their personal cry of alert we find a poetry wich is spontaneous, authentic and, above all, “resistent”. This is due mainly to the renewal of the poetical expression, impregnated with affective ness and intimism, which included colloquial language and devices used by all great Brazilian poetry since the modernism of 1922.

Aplicativos móveis para análise de problemas de fala

This paper presents two mobile applications developed for assistance on the analysis of speech related problems: Contagem de Disfluências (Disfluency Counter) and Velocidade de Leitura (Reading Speed). The use of tablet mobile devices streamlines the procedures for speech problem analysis conducted by speech language therapist. The lack of tabletspecific software designed for this purpose in the Portuguese language, and suited to the Brazilian needs, motivated the development of these applications, which was conducted according to the Kanban agile methodology.
