Added Resistance of an AUV Moving Inside a Water Pipeline Due to Wall Proximity
International Journal of Maritime Technology, 2015 This paper evaluates the added resistance of a torpedo shape AUV, moving inside a water pipeline, due to wall effects within the tube. Today, there are long length pipelines of water or petroleum that need to regular inspection.

Regeneration of the lizard heart after cryoinjury
Experimental Physiology, EarlyView.Abstract Lizards are renowned for their tremendous potential to heal tissues and organs after injury, but little is known about myocardial regeneration in reptiles generally. Here, we study cardiac regeneration in the leopard gecko (Eublepharis macularius) to fill the knowledge gap between traditional models of poikilothermic (zebrafish) and ...

AUV with Variable Vector Propeller
Journal of Robotics and Mechatronics, 2000 We developed an autonomous underwater vehicle (AUV) with a distributed controller and underwater acoustic communication. It is compact and lightweight thanks to its variable vector propeller and control using sophisticated logic circuits. Control is very precise using underwater ultrasonic command signals.

Design of a Buoyancy Controllable AUV by changing volume for data collection in the water column
, 2018 In this paper, we propose an AUV system design, named as Buoyancy Controllable AUV (BCA). The AUV is designed to smoothly explore narrow terrains, such as canyons or valleys, where existing AUVs have difficulties in performing missions.
