The paper describes the electromechanical design of a compact, light-weight Autonomous Underwater Vehicle (AUV) for archaeological applications; the vehicle is named Zeno (Zeno Environment Nautical Operator), protector of freshwater and flood victims, and was developed in the framework of the European project ARCHEOSUb; the AUV specifications, its navigation devices and payload are given. The main characteristics of the vehicle are described with particular attention to its system architecture, propulsion system and structural design. Zeno AUV is currently under assembly and its first tests are scheduled for Summer 2018.

The paper presents the electromechanical design of an Autonomous Surface Vehicle (ASV) developed by the Department of Industrial Engineering (DIEF) of the University of Florence (UNIFI), Italy. One of the main functions of this autonomous moving buoy is to localize underwater targets, such as Autonomous Underwater Vehicles (AUVs), through an Ultra Short BaseLine (USBL) and to enable the communication with them; furthermore, it is possible to equip the buoy with sensors or payloads, for instance cameras to detect the seabed. The buoy specifications and its navigation devices are described. The main features of the developed floating device are given, starting from its system architecture to its structural design. The buoy will be assembled during Summer 2019 and tested together with the UNIFI DIEF underwater vehicles.

Zeno (Zeno Environment Nautical Operator) is a compact AUV (Autonomous Underwater Vehicle) designed by the Department of Industrial Engineering of the University of Florence (UNIFI) and MDM Team S.r.l., an official spin-off company of UNIFI, within the ARCHEOSUb (Autonomous underwater Robotic and sensing systems for Cultural HEritage discovery cOnservation and in SitU valorization) European project and tailored for archaeological missions. One of the main purposes of this project is to develop low-cost AUVs, both used as a tool for services supporting the identification of new Underwater Cultural Heritage (UCH) sites and for the conservation, protection and enhancement of new and discovered ones (covering the first two phases of an archaeological campaign: search and inspection). The paper deals with the design, realization and testing of the vehicle. Its main features, payloads and implementation details are given. The official demos have already started and will be completed in autumn 2018; the different archaeological sites involved are in Italy and in Israel.

A new type of vehicle has been designed by the Department of Industrial Engineering of the University of Florence (DIEF); it is an AUV (Autonomous Underwater Vehicle) capable of switching its shape according to mission needs matching the best UUVs (Unmanned Underwater Vehicles) features: it is compact and near torpedo-shaped in case of long distance missions, such as surveillance and monitoring (closed configuration, typical of AUVs), on the other end it becomes isotropic for site inspection and on-site manipulation (open configuration, emblem of ROVs - Remotely Operated Vehicles). The main goal of the work is adding to the hydrodynamic vehicle the capability of changing its structure and its thruster configuration. The paper deals with the study and the design of the vehicle. Its main features, design choices and payloads, that can be equipped with, are described.

Robotic assistance to hand-impaired people represents an as difficult as important challenge. In this context, the research work of the Department of Industrial Engineering of the University of Florence (UNIFI) led to a tailor-made wearable device for rehabilitative and assistive purposes. In this paper, the synthesis of the development process, sequentially ordered, is given.
