The paper presents results of research on the development of robot perception systems. On the basis of the selected exemplary system, typical problems occurring during design of such systems were indicated. Those problems motivated the work set out to formalize the data flow by the use of metamodelling - the key technology of model-driven engineering. The obtained metamodel facilitates development of such systems and enables further creation of tools for models' editing, validation and automatic generation of relevant source code skeletons. Additionally, requirements for a robot perception systems runtime environment were identified and compared with existing component-based robot software frameworks.

W artykule przedstawiono wyniki prac poświęconych budowie układów percepcji systemów robotycznych. Na podstawie wybranego przykładu złożonego systemu percepcji wyróżniono typowe problemy występujące podczas projektowania takich systemów. W celu ich rozwiązania dokonano formalizacji modelu przepływu danych przy użyciu metamodelu - kluczowego elementu w inżynierii opartej na modelach. Opracowany metamodel ułatwia rozwój takich systemów oraz umożliwia stworzenie graficznych narzędzi do edycji modeli konkretnych systemów percepcji, ich walidacji, a ostatecznie do automatycznego generowania szkieletów kodu. Ponadto, zidentyfikowano wymagania odnośnie środowiska wykonawczego omawianej klasy układów oraz porównano je z istniejącymi ramowymi strukturami programowymi opartymi na podejściu komponentowym.

This paper presents a concept of component verification framework dedicated to a particular lightweight component environment. The starting point of the paper constitutes a discussion about the significance of verification of syntax in- consistencies in software development. Next, the need of verification in service-oriented and component-based systems is presented, and various approaches of verification in existing component environments are explained. The main part of the paper introduces a concept of functional integrity of component-based systems that utilize verification mechanisms which check consistency between components. The proposed solution is built on a fine-grained component environment (close to classes similarly to the Spring Framework) realized in the AgE platform. Selected technical aspects of framework design illustrate the considerations of the paper.

Criminal analysis processes is based on heterogeneous data processing. To support it, analysts utilize a large set of specialized tools, however they are usually designed to solve a particular problem are often incompatible with other existing tools and systems. Therefore, to fully leverage the existing supporting tools, their technological integration is required. In this paper we present original approach for integrating systems based on the component-driven paradigm. Firstly, a problem of supporting criminal analysis is described with a strong emphasis on the heterogeneity issues. Secondly, some theoretical information about integration is depicted followed by the details of the proposed architecture. Finally, the technological assumptions are discussed and prototype integration based on proposed concept is overviewed. om the experiments are discussed in the final part of the paper.
