Under water robotics are pretty cool. I do not know if it’s something I would do personally as a job but it is pretty interesting. They are helping the environment by fixing reefs such as the coral reef in Scotland. I like marine biology and oceanography that’s why chose to talk about this. I’m glad that they are able to be environmentally friendly. They aren’t dangerous for the world or for people and they can go lower than divers can in the ocean, they are like underwater divers. Under water robots are called AUVs sometimes. There are submarine AUVs too. The only thing that could possibly be wrong with the underwater robotics is that one of the rechargeable battery companies that most of the big AUVs use can be very dangerous if you don’t handle it very carefully, other than that they are extremely good for the environment. Also since they can go deeper than divers can they can get better pictures that human divers can’t. They will be able to take pictures of sharks and whales and other aquatic species that might harm humans if they took the picture.      

Interesting Facts about Underwater Robotics

The engineers, scientist, and biologist at one of the universities on Scotland is making autonomous underwater vehicles that will help fix the coral reefs in Scotland.  The robots that they are making will be able to dive more than a scuba diver is able to. They will be able to go two-hundred meters. The robots that are being crated are being designed after animal species that normally travel in groups, like ants and fish.  When they use their robotic arms, video, and image processer the robot can swim and will not bump into or crash anything. It will got to the bottom of the coral reef and will help the damaged coral reef a chance to survive. Under water robotics is apart of a National Science Foundation that costs about $2.5 million. Under water robotics is apart of a National Science Foundation that costs about $2.5 million.

AUV’s have an underwater acoustic system so they can move throughout the ocean. Underwater robots us a LBL system to navigate themselves, LBL stands for long baseline acoustic positioning system. The LBL navigation is used when robots are traveling along the base of the sea floor. Today most AUVs are able to to be recharged with rechargeable batteries and they are inserted with a type of Battery Management System. Most AUVs are using primary batteries so maybe they will have twice the strength at very low depths in the ocean. Some of the bigger AUVs use aluminum based semi-fuel cells so it can be powered. These battery powered robots must have special maintenance and also must have refills that are very expensive. These refills also make waste products that can be dangerous if not handled carefully.

Under Water Robotics

In this video two students, David Heinz and David Clifton, get an underwater robot and they take it apart piece by piece and explain what each part does. Some of the things they take apart are: the beluga that they use for testing, the vertical thruster, the foam top, and other things. This video also shows how the robotic moves in the water.

Since robots can do more in the ocean than humans can this is a good way for robots to take humans place in underwater activity. For humans it is dangerous and hard to explore the ocean. This machine is a combination of a remote controlled vehicle that has multiple thrusters to move it around and two robot arms. The creator of this robot (below) is Schilling Robotics.

Below the robot is called a biomimetic (which is a mimicking biology) lobster. It was created by the Northeastern University Marine Science Center. These kinds of robots may mimic muscle action, neuromophic sensors, they are like animal sensors. If a robot like 

This autonomous underwater robot was created as a prototype by students from the University of Sydney in Australia in the Australian Centre for field Robotics center. These prototypes might be able to monitor and explore the reef of the Great Barrier. The robot is called Oberon. It must stay attached to a boat that is on the surface of the water. The creators of the Oberon are predicting that in 10 years underwater robots will be able to be lowered onto the ocean’s floor and be able to be detached and will be able to map the terrain by itself.   

In this video it shows the first underwater computer. It is able to control an underwater robot, so if you are in the ocean and so is you are underwater robotic you can use this to guide it. You may think that this underwater computer is an iPad, but it is not. This underwater computer is a tablet; divers aren’t able to check their email. This computer tablet is used to communicate with underwater robots.

Merging of Computers and Robotics:

 By: Matt Billiot

In today’s world robotics have become very common, and is useful in under water exploration. The use of robots to explore the world’s oceans has become more advanced and useful. Stanford and Monterey Bay Aquarium Research Institute (MBARI) engineers designed a system that lets AUVs (autonomous underwater vehicles) to be able to detect objects in their way. It allows these robots to get pictures of the deep and scurry around the ocean. Since the AUVs can take multiple pictures in the same place has helped scientist look at the ocean and the deep ocean floor. A conservation biologist may want to see how marine species and its habitats are doing after a bottom trawling. A bottom trawling is a technique where a boat drags a fishing net over the floor of the ocean (another name for bottom trawling is dragging). The AUVs don’t change or damage anything for the different species and returns in the ocean; also can help measure the climate’s change. Taking pictures of the ocean floor isn't new at all. Sarah Houts a system software designer, made by her, has designed a program that allows vehicles to twist through ravines and other natural obstacles that are dangerous for underwater vehicle. Until now, scientists are able to control these tough spaces to be able to remotely steer a vehicle while being on another ship themselves. This operation is very expensive and not very capable of doing for explorations using monitoring periodically of the ocean ground. Stephen Rock, who is the director of Aerospace Robotics Laboratory, said, “It allows much greater flexibility. Aquarium researchers from the aquarium research institute have recently made AUVs that can make images of the ocean’s floor by themselves, but only on level places. Other researchers and Rock, himself, think that the most interesting science is hidden in canyons that steep down and other interesting areas. Rock said that we need to go into interesting places. Houts wants to make anticipory technology for a project that is similar to the MBARI so they can monitor changes and icebergs.
