4. Robots are an excellent choice for exploring places that are not easily accessible to humans,
such as the depths of the ocean. and they can go to the depths of the ocean to gather
information and pictures about the life of aquatic plants and animals.
All life came from the sea, but all robots were born on land. The vast majority of both industrial
and mobile robots operate on land, as the technology that allows them to operate in and out of
the ocean has only been available in recent years. Due to the unstructured, dangerous
underwater environment, a number of complex problems make it difficult to travel in the ocean,
whereas modern technology allows people to travel to Mars. The saline, aqueous and pressure
environment is huge.
5. Land-based mobile robots operate under almost
constant atmospheric pressure; Orientation legs
(or wheels or tracks) can work on a solid
foundation; no wages and no corrosion; they can
use simple visual sensations and can be observed
by their creators working in simple environments.
Instead, consider the environment in which
submarines should work. The pressure they are
exposed to can be very large, so extremely robust
designs are required. The height of the deep
oceans varies between 19,000 and 36,000 feet. At a
depth of only 33 feet, the pressure will be twice
the normal atmospheric pressure of 29.4 psi.
6. Sometimes it is enough to lower the TV cable to check the sunken ship. If it is important to
inspect an underwater object from the inside and the depths do not allow the use of a
diver, an autonomous, free-moving robot is simply irreplaceable here. It is only
important that the robot finds its way back.
And it needs strong brains to do that. Modern computer processors can easily handle most
tasks, the main thing is to have the right software. This is the main difficulty in
creating robots. But this is a lucrative business. Programs are constantly being
improved.
7. If the robot is equipped with appropriate
manipulators, then it can easily do something
under water - screw and unscrew, cut and weld,
lower loads to the ground and lift them to the
surface. And do it for hours - not afraid of high
blood pressure, decompression sickness and
hypothermia.
8. The most interesting task for robots is to inspect and clean the inside of water pipes
and sewer systems, which are generally inaccessible to humans. Thus, the Delaware
Pipeline, one of the longest water tunnels in the world, has cracks that allow thousands
of cubic meters of water to flow out every day. A miniature robotic submarine will be
used to repair the tunnel.
Currently, two unmanned submarines are actively used in the construction of the
Russian-Turkish gas pipeline "Blue Stream", which runs along the bottom of the Black
Sea.
9. Recently, a 17th-century British warship carrying ten tons of
silver and 100 tons of gold coins was discovered in the Strait
of Gibraltar. The total "product" can reach $ 4 billion. It is true
that so far submarine robots have been able to lift only the
cannon, cannon and some other parts of the ship from a
depth of 800 meters.
10. The Chinese-made Haixing 6000 submarine broke the world record for its research
at 6,001 meters below sea level. It is China's first remote-controlled
submarine. The robot was developed by a group of specialists from the
Shenyang Automation Institute of the Chinese Academy of Sciences.
11. Conclusion
02
The underwater environment is extremely
hostile forhuman engineering activities. In
addition to high pres-sures and
hydrodynamic forces that are both
nonlinearand unpredictable, water is not an
appropriate media forelectromagnetic
communication except at short ranges.This
pushes underwater technology to rely on
acousticcommunication and positioning
systems that are charac-terized by low
bandwidth. On the other hand, the oceanis
extremely important for numerous human
activitiesfrom the commercial, cultural, and
environmental pointsof view.Research on
underwater robotic applications is ac-tive
both from the technological and
methodological aspects.
