The present work focuses on the integration of the UUV component in the overall structure and in the development of the its remote guidance system. The robotic platform consists of a small ASV that can serve as supply vessel for a micro-UUV, which is remotely guided by a pilot from a shore-ground station. A robotic structure of that kind is considered in this work, which continues the. The issue of making available efficient, versatile and cost effective solutions for exploring, monitoring and exploiting the marine environment is a challenge that can be tackled by developing integrated robotic platforms, where autonomous surface vehicles (ASV) cooperates with unmanned underwater vehicles (UUV). Furthermore, small-scale HUAVs offer the advantages of low cost and easy operation. Hoveringat a point enables us to make more eff- tive observations of a target. Among the wide variety of UAVs that have been developed, small-scale HUAVs (helicopter-based UAVs) have the ability to take off and land vertically as well as the ability to cruise in ight, but their most importantcapability is hovering. Recently, however, demand has arisen for UAVs such as aero-robotsand ying robotsthat can be used in emergency situations and in industrial applications. Since the development of the rst UAVs, research efforts have been focused on military applications. In part- ular, UAVs have many applications in emergency situations humans often cannot come close to a dangerous natural disaster such as an earthquake, a ood, an active volcano, or a nuclear disaster. In recent decades, the development of - manned autonomous vehicles have been of great interest, and different kinds of autonomous vehicles have been studied and developed all over the world. UAVs, UGVs, AUVs, and ASVs are called UVs (unmanned vehicles) nowadays. Based on their working environment, a rough classi cation of the autonomous vehicles would include unmanned aerial vehicles (UAVs), - manned ground vehicles (UGVs), autonomous underwater vehicles (AUVs), and autonomous surface vehicles (ASVs).

The advance in robotics has boosted the application of autonomous vehicles to perform tedious and risky tasks or to be cost-effective substitutes for their - man counterparts. The new strategy, tested over a Proportional/Integral/Differential (PID) controller for a vertical mono-rotor plant, provides low-cost real-time support to the controller and friendly remote access from mobile devices to the practices for the students. Finally, the JavaScript development and runtime platform Node.js is used 1) to develop and run the Javascript laboratory web sever within the Raspberry Pi and 2) to support the communications between the laboratory front-end and server. The Raspberry Pi, a low-cost single-board computer, is in charge of running 1) the C program that closes the control loop over the selected plant and 2) the JavaScript laboratory web server that hosts the laboratory front-end and communicates it with the controller.

EJsS is used to create a JavaScript and HTML5 laboratory front-end that lets teachers and students parametrize and observe the behavior of the controllers/systems under study from the web-browsers of their tablets and smartphones. This paper presents a new approach to develop remote practices for Systems Engineering and Automatic Control laboratories based on Easy JavaScript Simulations (EJsS), Raspberry Pi and Node.js.
