Experimental testing of asymmetric underwater acoustic networks [PDF]

2014 IEEE Fifth International Conference on Communications and Electronics (ICCE), 2014
om. {asilva.sjesus}@ ualg.pt Abstract-The coordinated operation of multiple vehicles within the framework of multipoint non-cabled observatories and offshore activities sprung the necessity for complex underwater acoustic networks (VANs). An example of such VAN consisting of fixed and mobile underwater nodes, was recently developed and tested at sea. A

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

An Architecture for Cooperative Localization in Underwater Acoustic Networks [PDF]

Proceedings of the 10th International Conference on Underwater Networks & Systems, 2015
This paper outlines an architecture for underwater acoustic cooperative localization. Our system leverages communication within an acoustic network to both share navigation information and measure the relative range between vehicles. We employ a factor graph framework for vehicle position estimation.
