A current challenge for AUV missions is to combine long endurance with high manoeuvrability. The proposed Pipefish AUV is a long endurance AUV capable of high quality survey missions that can deliver multiple hover capable AUVs to sites of interest. The Pipefish AUV and the small vehicles can perform cooperative tasks and reach remote locations without the need for a monitoring surface vessel. It...
Remotely Operated Vehicles (ROVs) are a proven tool for performing highly-capable marine operations ranging from science investigations to industrial applications. While industry-grade ROVs can support an impressive array of functions, they can be very expensive and complex. As such, they are often inappropriate for use in educational programs where functional requirements are limited but low-cost...
Autonomous Surface Vessels (ASV) are capable of performing a wide range of tasks given the emergence of state-of-the-art sensors, wireless communications links, autopilots and supervisory control systems. This paper describes prototyping efforts for a new, low-cost, portable ASV specifically developed for transport by helicopter and backpack in the Arctic. A prototype of this new ASV was developed...
The number of connected devices — also known as Internet of Things (IoT) — is exponentially increasing. Such sensors and devices also appear in transportation systems giving some intelligence to roads, equipment and vehicles. Nowadays, it is possible to communicate with the environment in order to have better everyday services. Furthermore, the number of registered — public or private — Electric Vehicle...
The aspects of energy conservation and environmental protection are the need of the hour. Hence, the battery electric vehicles came into existence and are operated for various purposes. The most important part of these vehicles is the safety systems. The operation of the safety systems installed in Pedal Assembly, Dash Board, Battery pack, Motor Controller can be made less complicated and faster by...
Studies have shown that in places like New York City drivers often spend over 20 min looking for parking, contributing to as much as 30% of the total traffic. In response, cities like San Francisco have deployed systems capable of pointing drivers to the closest available parking spot. Unfortunately, such systems have gained little traction as they rely on specialized infrastructure that is expensive...
This paper describes a new class of autonomous marine vehicles named Medusa and highlights their role in a number of EU projects addressing multiple vehicle scenarios. The MEDUSA vehicles, with surface and diving versions, were designed and built at the Institute for Systems and Robotics, IST, Univ. de Lisboa, Portugal as a result of an effort aimed at affording researchers and practitioners of marine...
Due to the increasing awareness of oil depletion and the growing appreciation for green technology, electric vehicles (EVs) are now a widespread form of vehicle transportation. Single-source EVs such as battery electric vehicles (BEVs) have the drawbacks of limited life cycles and self-discharge. This paper proposes a test bench model to evaluate the performance of a multi-source light electric vehicle...
The proposed work aims to describe the “V-FIDES” project, focused on developing a new generation of agile, over-actuated, long endurance Autonomous Underwater Vehicles, for deep underwater exploration, operation and environmental monitoring. The project, co-funded by Tuscany Region (Italy), has been developed by a team lead by WASS S.p.A. (Whitehead Sistemi Subacquei, Livorno), with the participation...
Unmanned surface vehicles (USV) increasingly gain importance in all areas of marine engineering and natural sciences. Different measuring vehicles are used for short-term measurements with various adaptable sensors. The operation time of these vehicles is limited to few hours. Moreover, long endurance vehicles were designed for long-term missions, generating energy from solar, wind or waves, which...
The needs of Marine Vehicles have increased day by day according to the utilization benefits and minimum risk during the operation [1]. Some of the main task has proved just only carried by Marine Unmanned Vehicle. One is an Unmanned Surface Vehicle (USV). Which has the ability to do a good observation at sea level or below sea level. This vehicle has a feature in the design, which is where most of...
Traditional battery-powered wireless sensor networks face many challenges to meet the requirements of a wide range of demanding applications nowadays due to their limited energy. Although energy harvesting techniques can scavenge energy from the environment to sustain network operations, dynamics from the energy sources may lead to service interruption or performance degradation when the sources are...
Autonomous Underwater Vehicles (AUV) are slow-moving small unmanned robots capable of swimming independently below the water surface on pre-defined mission paths and are commonly used for oceanographic exploration, bathymetric surveys and military applications. With the use of appropriate sensors and equipment, AUVs can perform underwater object recognition and obstacle avoidance. Amogh is a miniature...
The robotics world has reached a stage where the Remotely Operated Vehicle (ROV) industry is very well established with thousands upon thousands of ROVs having been created and deployed since the dawn of this industry. The need for autonomy in robots and vehicles, however, is becoming more and more a prevalent issue in many situations and environments worldwide. The ability to communicate between...
It is the purpose of this paper to encourage the use of unmanned aerial vehicles (UAVs) for the development of interdisciplinary engineering education projects. The use of UAVs is an excellent tool to gather students from various engineering and science fields. This paper explores the different features that a four-rotor UAV is used for STEM education including the training of undergraduate students...
The main objective of this paper is to illustrate an Integrated Territorial System of Sustainable Mobility and Micro Smart Grids developed by the Pole for Sustainable Mobility (POMOS) and its partners, in the framework of a regional R&D project named “Bonifica 2.0”. This project aims at the touristic exploitation of the Pontine territory, a large naturalistic area in the region of Lazio in Italy,...
Several recent works have studied the schedule for mobile vehicles to recharge sensor nodes via wireless energy transfer technologies. Unfortunately, most of them overlooked the important factors of the vehicles' moving energy consumption and limited recharging capacity. These oversights may lead to problematic schedules or even stranded vehicles. In this paper, we study the recharging schedule that...
Buoyancy-driven underwater gliders (UGs) have proven to be quite effective for long-range, long-term oceanographic sampling. However, current off-the-shelf UGs are large, heavy, expensive, and difficult to modify, both in hardware and software, which prevents their frequent use for lake observations and limits researchers' ability to perform multi-vehicle coordination experiments. Our current research...
This paper describes system identification, estimation and control of translational motion and heading angle for a cost effective open-source quadcopter — the MikroKopter. The dynamics of its built-in sensors, roll and pitch attitude controller, and system latencies are determined and used to design a computationally inexpensive multi-rate velocity estimator that fuses data from the built-in inertial...
Battery systems for electric vehicles (EVs) or uninterruptible micro-gridsâ"prototypical cyber-physical systems (CPSs)â"are usually built with several hundreds/thousands of battery cells. How to deal with the inevitable failure of cells quickly and cost-effectively for vehicle warranty or uninterruptible service, for instance, is key to the development of large-scale battery systems.
