Summary:Remote laboratories are laboratories where the hardware devices are accessible through the Internet 24 h a day for running experiments on physical processes. These laboratories are commonly used as complementary tools in engineering education, allowing students to integrate theoretical notions with practical experiments without the necessity of being physically present inside a laboratory. The increased availability of experiments in a remote laboratory is certainly an advantage for students, but it implies an increase of the probability of hardware and software failures. Thus, maintaining physical processes in a remote laboratory may become a heavy task for laboratory administrators. Remote laboratory inefficiency due to hardware and software maintenance can be certainly reduced if the time that is required for software reinstallation and/or upgrade is kept as short as possible. In this paper, a technique based on the use of a bootable (live) device on the server side of a remote laboratory is reported. This solution, which, in principle, can be used in almost any remote laboratory, allows an administrator to greatly reduce the time that is needed to fix a hardware/software failure, as well as to add a new process to the laboratory in a faster way. Moreover, the use of such a tool will also increase the reliability of the entire laboratory. The application of the proposed method to the ldquoAutomatic Control Telelab,rdquo which is a remote laboratory that was developed at the University of Siena, is also described in detail.
