With the depletion of land resources, marine resources development and utilization become increasingly apparent. Accompanied by the development of marine resources from nearshore extension to the deep ocean, Unmanned Underwater Vehicles (UUVs) become key instruments. Generally, UUVs include autonomous and tethered types; each has its advantages and disadvantages. Through the use of combined vehicle...
Underwater data collection by using Autonomous Underwater Vehicles (AUVs) is increasing within the oceanographic research community. AUVs are remarkable machines that processed data for gathering local bathymetric information, which have been developed, investigated and utilized for various purposes. In this study, the Iver2 AUV is examined to accomplish location mapping by well-planned trajectory...
In order to mimic a real fish, the back bracket of a biomimetic-underwater vehicle's (BAUV's) tail fin is composed of aluminum spacers with a flexible aluminum plate as the tail spline. The sway of the tail fin is driven by a motor and its motion is impeded by the water such that the rotation angle of the tail fin could not be calculated simply by a coordinate conversion. For precise tail fin control...
Fishes can avoid colliding with obstacles and track baits depending on the lateral distributed sense nodes which can sense the pressure variances of the surrounding flow field. Moreover, the interacted acoustic pressure field between the tail and the wall can provide useful information of the fish location by extracting the physical meaning of the sense node's measurement. Therefore, this study provides...
