but in fact it could transform not only how engineers think about building underwater vehicles, but how biologists think about movement at large. take a look at the gif below. that’s a swimming lamprey, surrounded by millions of miniscule glass beads. by shining lasers into the tank and re...
But for realistic fish-like swimming in strong currents such robots will benefit from closed-loop feedback. We demonstrate how this can be achieved, underwater, using a stretchy neoprene sensing skin with embedded, discrete dielectric elastomer stretch sensors. The latest prototype skin, with 8 ...

A large public dataset with low-resolution underwater videos and images has also been developed to test the proposed system under worst case conditions. Citation: Petrellis, N.; Keramidas, G.; Antonopoulos, C.P.; Voros, N. Fish Monitoring from Low-Contrast Underwater Images. Electronics 2023...

The system proposed can monitor water quality parameters, tank status, the feed falling and fish swimming depth and velocity. In addition, the system includes a smart algorithm to reduce the energy waste when sending the information from the node to the database. The system is composed of ...
Mating occurs in autumn, when water temperature is about 5 ◦C. At mating, the male deposits the spermatophores on the ventral side of the female. Egg hatching occurs in December or January, when the released eggs are attached to the hairy pleopods under the tail. The incubation period ...
While acoustic cameras are capable of capturing underwater videos, which enable investigations of fish behavior, a long-term deployment "in the field" is limited due to equipment as well as operational costs. During the deployment of the DIDSON and ARIS systems, personnel had to be present on ...
