Design and control of an unmanned surface vehicle for environmental monitoring applications
(Institute of Electrical and Electronics Engineers Inc., 2017) Villa Ramírez, José Luis; Paez J.; Quintero C.; Yime E.; Cabrera J.; Lindado H.C.
Unmanned Surface Vehicles (USV) have been used in a wide range of applications, in particular in environmental monitoring. In this work we propose the design and control of an USV which is intended to be used for monitoring environmental variables of the main inlet waters located in Cartagena de Indias, Colombia, such as Chambacu, Cabrero and San Lazaro. The paper shows the results obtained in the naval design, focused on the hull design, and the control strategy for unmanned navigability which is tested in simulation. © 2016 IEEE.
Implementation of an Unmanned Surface Vehicle for Environmental Monitoring Applications

Environmental monitoring in inland waters is an important issue for adequate planning and management of this kind of territories. This paper shows the implementation of the concepts and strategies for a boat to follow a pre-established route through waypoints oriented to these water bodies. An extended Kalman filter is used to estimate orientation and position using the readings of an inertial unit fused with a magnetometer and GPS. The strategy shows to be valid in calm conditions, which is sufficient for the mission. © 2018 IEEE.
Sustainable boat transportation throughout electrification of propulsion systems: Challenges and opportunities
(Institute of Electrical and Electronics Engineers Inc., 2019) Campillo Jiménez, Javier Eduardo; Domínguez Jiménez, Juan Antonio; Cabrera J.
Global use of carbon-based fuels increased by 1.6 % in 2017 and continued increasing in 2018, after managing to maintain emissions flat between 2014-2017. This trend deviates from the emissions trajectory required to fulfill the climate change goals to maintain the earth's temperature below 2-degrees. The transport sector accounts for about a quarter of these emissions but its the sector with the highest dependence on fossil-fuels. In order to reduce emissions, several approaches have been taken, from increasing fuel efficiency to the use of alternative fuels altogether. The most recent trend leans towards electrifiying the transport sector. High penetration of mature renewable energy technologies such as wind and solar photovoltaics as well as energy storage improvements are leading the way. While mass adoption of electric-propulsion systems for boats are still years away, recent pilot projects suggest that electrifying boats for passenger transportation may be not only a sustainable transport solution but its lower operation costs could facilitate its penetration on densely populated coastal and river cities where conventional public transport systems are reaching their full capacity. © 2019 IEEE.
