In the field of mobile robotics, the process of robot localization and global trajectory planning in robot operating scenes, that are completely or partially known, represents one of the main issues that are essential for providing the desired robot functionality. This paper introduces the basic elements of path planning for an autonomous mobile robot equipped with sonar sensors, operating in a static environment. The path planning process is initially performed by using a known map. Next, the sonar sensors are used to localize the robot, based on obstacle avoidance techniques. The effectiveness and efficiency of the algorithm proposed in this paper is demonstrated by the simulation results.

Abstract-This paper describes an experimental system that has been designed, implemented and tested for object recognition and tracking in still, respectively dynamic imagessuccessive video frames captured in real time (live) with a web camera -based on Intel's open source computer vision functions library, OpenCV (Open Source Computer Vision). We propose a real-time object recognition system in intelligent library environments. The system consists of two key modules: feature extraction and object recognition. Specific detectors such as SIFT (Scale-Invariant Feature Transform) and SURF (Speeded Up Feature Robust) are efficient methods that provide high quality features, yet are too computational for use in real-time applications.This paper also proposes a low complexity, robust object recognition and tracking method using advanced real time feature matching. It combines Microsoft Visual Studio 2008 Express Edition C# with OpenCV Function library using SURF algorithm in Emgu CV to develop the software. The tests showed that the proposed system and method are more efficient and more robust than in most traditional applications.Index Terms-Computer vision, object recognition, object tracking, OpenCV, SURF. I. INTRODUCTIONResearch in the field of library automation is characterized by a long history of robot assistance applications such as book cataloguing, retrieval and return [1], [2]. The studies focused on solving the technical problems at fixed locations in the library. Mobile robots [3], [4] which are both autonomous and capable to detect and react to environmental factors have recently attracted the attention of libraries. Some libraries have introduced mobile robots and use them to guide student users towards the adequate shelf [5], [6]. However, there are only a few cases in which educational research has addressed the field of service robot applications [7]-[9] designed for use in libraries. These studies have emphasized the general trend which regards robots as adequate agents to ensure user guidance and involvement in learning activities.References vision due to its numerous applications.Object recognition and tracking are major tasks in several computer vision applications, such as Augmented Reality (AR), interactive systems and robotic systems.Some of the main advantages of vision systems, in robotic applications, are the simplicity of the algorithm, the low cost, and the reduced need for maintenance, while aspects such as fast and effective identification are still unsolved. Even though adequately efficient and accurate algorithms have been developed, the processing speed still fails to meet the modern manufacturing requirements [18].Most of the objects tracking approaches based on feature matching are highly computational and less robust in various environments. To efficiently track an object in a video sequence, at first, feature points are extracted from the object of interest. The extracted objects then recognize the target object, and the detected object is continuously tracked on the input stre...

Creating a special Web software application that will present the library services and resources requires special skills in the field of Web technologies. The developed Web application allows quick access to important information about the library since it requires only a few taps on the touch screen to access and view the desired information. The software is intended to enhance user real time access to information regarding the library’s newest book acquisitions, databases free trial, events.
