The paper deals with the application of the rapid prototyping technique for control system modeling. The proposed methodology is applied to creating a fuzzy controller that can be used to avoid collisions of a wheeled mobile robot with obstacles. In the paper there is described how to combine and apply two well-known development environments, that is, Microsoft® Robotics Developer Studio and MATLAB® software for rapid prototyping purposes. Important components of the proposed framework such as Visual Programming Language, Visual Simulation Environment and Fuzzy Logic Toolbox are briefly discussed. The main part of the paper focuses on the implementation of a few variants of the fuzzy controller for managing the robot movements in the virtual world (Tab. 1). These controllers differ from each other in such properties as the type of a distance sensor and the number of rules included in the fuzzy knowledge base. The merits and limits of the elaborated solution are considered taking into account the results obtained during verification tests. These experiments were carried out with the use of several environments of different complexity. The results of the verification tests which are included in Tab. 2 show the effectiveness of the proposed approach.
