International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Until the early 80's, telemetry processing systems were commonly run on mainframe or mini computers running proprietary operating systems and software with limited portability. The advent of the 'low-cost' workstation reduced the hardware cost but the software still remained relatively expensive and relatively mission specific. The workstation itself, although comparatively cheap, was not, and is still not, an everyday piece of computing hardware Telemetry Processing software has been developed by Micro SciTech to meet both low-cost hardware requirements and mission independence. It runs on networked IBM PC compatible computers and can be re-configured and used for many different missions and experiments without the need for extensive software rewrites.

Den här rapporten innehåller information om hur man skapar en länk mellan en dator och ett minne via en dators serieport. Ett RS232-protokoll används för att upprätthålla den här länken. För att ta hand om minnet samt upprätthålla kommunikationen med datorn har en FPGA programmerats. Intel hex8 formatet används för datan. Ett program för Windows 98 skapades också. Programmet öppnar en fil och läser tecken. Tecknen översätts till heltal som sänds till serieporten. Programmet kan också spara data till en fil. Data hämtas från minnet via serieporten. / This report contains information how to establish a link between a computer and a memory through the serialport of a computer. The RS232 protocol is used to establish this link. To handle the memory and the communication with the computer a FPGA has been programmed. The data is in Intel hex8 format. A program for Windows 98 were also created. The program opens a file and reads characters from it. The charcters are translated into integers which are sent to the serialport. The program can also store data, recieved from the serialport, to a file.

The main goal of this master’s thesis is to over study, reconsider and make a program, which will be capable to interpose information from GPS module, different markers and necessary information’s, geographic coordinates obtained from GPS will be projected in its interface and also on map. This project contains of 3 parts. The first one exactly describes GPS, its history, structure, principle, competitive types of navigations systems and also GPS’ services and technical parameters. The second part of this project describes GPS hardware, used receiver of this signal. There is also mentioned its technical parameters and communication with outside world. The third part is in scripted the software for communication with GPS receiver. We can also see the description of code, in which is mentioned communication protocol and imaging the position on the map. It was programmed in C# language on platform Microsoft Visual Studio 2008 Express Edition.

Thesis discuss about effort to ensure from error, which may occur during transmission over noisy channel. There's used Reed Solomon code. It's block, cyclic and systematic code, which is symbol orientated. Computational process of decoding is mathematically time-consuming. In thesis is closely described Berlekamp-Masey algorithm, used in decoding to evaluate error polynomial. Process is illustrated in application in Matlab. Practical realization uses Reed Solomon code in communication over RS232. Communication is established between computer and microcomputer.

Com a necessidade de substituir o trabalho humano em áreas de risco, ambientes impróprios ou inalcançáveis, diversos centros de pesquisas e universidades têm desenvolvido aplicações e estratégias de controle para robôs móveis. Porém, o alto custo na aquisição de um ou mais protótipos para estudos e desenvolvimento de novas tecnologias pode se tornar um fator limitante para o incremento dessas pesquisas. Como parte de uma solução para contornar esta eventual limitação em robótica móvel, uma arquitetura de baixo custo, modular e expansível é apresentada neste trabalho. São apresentadas também as metodologias de desenvolvimento dos módulos, os algoritmos de controle, as interfaces de comunicação e os principais componentes utilizados para desenvolvimento do robô móvel ZEUS, cujo sistema eletrônico de controle é a implementação da arquitetura proposta. Análise de custo, resultados experimentais de sensoriamento e navegação concluem este trabalho. / With the need to replace human work in risk\'s areas, improper or unreachable environments, several research centers, and universities have developed applications and strategies for mobile robots control. However, the high acquisition cost of one or more prototypes used for research and in development of new technologies may become a limiting factor. As part of the solution to get a round any such limitation on mobile robotics, a modular and expandable low-cost architecture is presented in this work. There are also presented the methodologies for modules development, the algorithms of control, the communication interfaces and the main components used for the development of ZEUS mobile robot, whose electronic system control is the implementation of the proposed architecture. Analysis of cost, experimental results of the sensing and the navigation system conclude this work.
