The experimental results of fuzzy based indoor navigation system are presented in this article. The system was built with simplicity in mind, employing roof mounted visual sensors and fuzzy logic for the guidance and positioning of an autonomous mobility device with real-life noisy and delayed visual data processing. The fuzzy control strategy presented bellow works on a given (predefined) trajectory...
The novel technology, which is dedicated to assist the person with disabilities, is presented in the work. It is the discrete eye tracking system which recognizes the users command from voluntary controlled eye motion. The user wears the head mounted device, which consist of glasses with fixed on it video camera. The system was tested with three on-line applications. First - the control of the mobile...
How to extract information intensively from cardio signals for the diagnosis of diseases and assessment of heart function is a topical subject. Heart is not a periodic oscillator under normal physiologic conditions and standard linear measures may not be able to detect subtle, but important changes in heart time series, whereas, most of nonlinear measures suffer from the curse of dimensionally. In...
New approach to design inverted pendulum as a teaching aid is presented; it is based on the application of piezoelectric actuators that generate motion in one or two directions, depending on the number of degrees-of-freedom of inverted pendulum. High resolution and fast response time of piezoelectric drives make the control algorithms more effective than in case of using electrical motors. In the...
this work presents the discrete eye tracking system which is based on principal component analysis (PCA) and the neural classifier. The system use head mounted device. The user wears an ordinary cap with mounted on it Web-cam and mirror which reflects the eye to the camera. The system was tested with two on-line applications. First - the control of the mobile robot in the maze and second application...
Design of efficient control algorithms for autonomous mobile robot movement in unknown and changing environment with obstacles and walls is a difficult task. There exist different strategies to design control systems to perform the robot movement. In this article possibility to use fuzzy logic, if-then rules, and genetic algorithm for autonomous mobile robot control is presented. Control using fuzzy...
