- AUV Control and Communication using Underwater Acoustic NetworksPublication . Marques, E.; Pinto, J.; Kragelund, S.; Dias, P.; Madureira, L.; Sousa, A.; Correia, M.; Ferreira, H.; Gonçalves, R.; Martins, R.; Horner, D.; Healey, A. J.; Gonçalves, G.; Sousa, J. B.Underwater acoustic networks can be quite effective to establish communication links between autonomous underwater vehicles (AUVs) and other vehicles or control units, enabling complex vehicle applications and control scenarios. A communications and control framework to support the use of underwater acoustic networks and sample application scenarios are described for single and multi-AUV operation.
- Marine Operations with the SWORDFISH Autonomous Surface VehiclePublication . Ferreira, Hugo; Martins, R.; Marques, E.; Pinto, J.; Martins, A.; Almeida, J. M.; Sousa, J. B.; Silva, E. P.This paper describes the design and development of the Swordfish Autonomous Surface Vehicle (ASV) system. The work focuses the sensors, actuators, communications and C4I of an unmanned vehicle for marine operations. SWORDFISH is an autonomous surface vehicle used as the central communications link between air, undersea, and terrestrial robotic vehicles of a network centric operation. It is used as a test bed platform for deployment and testing of advanced control and operational concepts for multi-vehicles systems. This new unmanned marine vehicle was done in the context of the PISCIS project. The PISCIS project concerns the development, test and evaluation of new vehicles and new concepts of operation for networked vehicle systems in oceanographic data collection. The PISCIS system includes two autonomous underwater vehicles, the Swordfish ASV, an acoustic navigation system, acoustic and radio communications and a distributed command and control system.
- Swordfish: an Autonomous Surface Vehicle for Network Centric OperationsPublication . Ferreira, H.; Martins, R.; Marques, E.; Pinto, J.; Martins, A. O.; Almeida, J. M.; Sousa, J. B.; Silva, E. P.The design and development of the swordfish autonomous surface vehicle (ASV) system is discussed. Swordfish is an ocean capable 4.5 m long catamaran designed for network centric operations (with ocean and air going vehicles and human operators). In the basic configuration, Swordfish is both a survey vehicle and a communications node with gateways for broadband, Wi-Fi and GSM transports and underwater acoustic modems. In another configuration, Swordfish mounts a docking station for the autonomous underwater vehicle Isurus from Porto University. Swordfish has an advanced control architecture for multi-vehicle operations with mixed initiative interactions (human operators are allowed to interact with the control loops).
