Autonomous underwater vehicles: future platforms for fishery industry

U0300643 Cheong Chong Kiat Underwater vehicles had been around for 2 centuries or more and the fishery industry starts way back before civilization where people hunt for food on land, above sky and under the sea. Nowadays, this high-tech automation combined with this traditional industry forms a potential industry or even new research area like monitoring endangered species of marine mammals (in ecosystem studies)or predicting huge catch in the monsoon season (assessment of fish stock). Autonomous underwater vehicles (AUV) are today new development of underwater vehicle that can be classified as manned or unmanned systems. AUVs are programmed to execute some underwater “missions” that may involve danger to the human if they are the ones to conduct these tasks. Deep under the sea, there are unforeseen undercurrents that are beyond people imagination. With the typically small, quiet, and have the potential to operate at low cost and be unconstrained by the vagaries of weather AUV, people can remotely view the events going on in the dark and murky environment while they are above sea. Time and money are wisely spent on improving system such as acoustic system and communication link from the target (school of fish) to the person who monitor via the Unmanned Undersea Vehicle (UUV). After gathering the data and information and through detail analysis, the UUV is retrieved back for regular maintenance and next inspection for the next bout. UUV are truly the best right-hand “man” in the fishery industry and even research on fishery science for the universities.

The deep sea is probably the last frontier not explored on earth. So far, due to the immense pressures at work deep in the ocean, not human has been able to observe the eco-structure of the deep ocean.

Few samples of the creatures living in the deep ocean have been found. Their habits are virtually unknown. With these autonomous underwater vehicles, the mysteries of the deep may finally be solved.

After waking up from my nap during a MRT ride home, I remember that AUV can bring us fortune too, such as digging up the long-lost treaure or ship. Just like the "Titanic".

The one use for Titanic exploration are uuvs not auv. I do not think auv have that capability yet.

Maybe something model like a real-like fish can dive into the deepest seabed without any internal exploding or malfunction during the expedition. Anything is possible now with massive expertise here and there.

This robot is quite good because the world is facing problems like overfishing and the destruction of marine life. This AUV can be used to study the marine life which can then lead to conservation of earth's precious natural resources. However, the AUV must be fully equip with obstacle avoidance algorithm because it can be very difficult to navigate underwater. It will take a longer time for the AUV to avoid obstacles due to the water resistance and currents as compared to a robot moving on land. I do believe more research into this area will be needed.

One is really used for water sampling and monitoring, a second is used for mapping the seafloor, and a third is used to take photographs of the ocean bottom
