The web interface for the system was developed using HTML, PHP, and AJAX along with JAVA to build graphical real-time interfaces for the experiments that can work on any operating system platform (Windows, Mac OS, Linux, Unix, BeOS) on PCs and mobile devices. The Arduino ® Microcontroller was used to establish the interface platform with various laboratory devices using C and C++ programming languages to control input/output signals for a specific lab device. The UoB-iLab architecture is designed to be used with limited internet bandwidth and concurrent access by users and administrators.
This work presents a new design for an internet laboratory at University of Baghdad (UoB-iLab) that can be used by students off-campus to execute real time experiments in the on-campus. Moreover, it improves the user interaction with real labs, providing a real-time visualization of experiments and lab instruments by means of the control of video camera placed into lab, and the transmission of video streaming with different quality to users. Unlike other lab systems, RVLab is adapted to devices and instruments of any real laboratory due to a secure and robust mechanism that allows the remote execution of lab programs. RVLab affords support for the basic requirements of these systems such as the user management or the resources (instruments and devices) reservation. This paper presents a new framework, RVLab, to help developers building flexible and robust server-side virtual and remotes laboratories quickly.

Generally these virtual/remotes laboratories are built from scratch again and again, instead of reusing software and hardware infrastructures. Currently, virtual/remotes laboratories are often being built to improve learning and researching capabilities in some areas of knowledge.
