A MATLAB-BASED MODEL OF ROBOT CONTROLLED BY VISUAL FEEDBACK OVER THE INTERNET Simeon Tsvetanov 1 1 Institute of Computer and Communication Systems– Sofia, Acad. G. Bonchev str, Bl. 2, 1113 Sofia [email protected] Abstract – This paper presents the design and exploitation issue of an experimental laboratory for monitoring and control of a robot model. The laboratory is available over the Internet. This approach allows remote users to obtain access to the distributed software resources for control of the robot’s video camera and to explore the work scene. The software suite is developed to support functionality of a virtual laboratory interfacing the distant user control influences to Matlab base software performing robot simulations. The virtual laboratory is applied for learning and education. Keywords – IT, Computer Systems, Computer Modeling. 1. INTRODUCTION Recent trends in developing information services over the Internet concerns the remote access to computational, informational and technological resources [6 7]. This access allows complex technical devices to be online available for utilization by many users. This remote utilization of technical resources through the Internet is called a “Virtual Laboratory” [8]. The methods of the virtual laboratory are widely applicable for the field of e-learning and e-training [9]. This paper presents the design and exploitation issue of an experimental laboratory for monitoring and controlling a robot model. The robot’s movement and video camera adjustment is controlled by the remote incoming command of the user through the Internet, or distance navigation. 2. ARCHITECTURE OF THE VIRTUAL LABORATORY The analytical motion of the robot is tracked through a software model in the Matlab software suite. An interactive implementation of the model is deployed for different streams of input data, loaded from predefined files. These files are preceded by a server system, which manages the remote interface with the user. The suites of the server’s programs present the results of the modeling in graphical and interactive view. The server’s programs are implemented with PHP server coding. The PHP interpreter uses the graphical library GD for extending the graphical functionality and to keep the interface for controlling the robot. The remote client can be any browser, for instance: Explorer, Netscape and others. The system architecture of the virtual laboratory is
