welcome to TTI welcome to the whole new world of science and robotics today we
are going to explore the incredible world of robotic sea creatures so watch
the entire video to discover something new in something robotic most of us have
probably eaten fish and maybe I've even had a pet goldfish but few of us have
seen a robotic fish fish is another underwater inhabitant which help us
detect water contamination but guys do you ever think how to control the level
of water pollution you can take samples and analyze it in the laboratory or you
can do it the smart way by using a specifically designed robot in the form
of a fish that will float in the water and be capable of checking the waters
purity the University of Essex has developed a robot fish in order to
fulfill water monitoring needs there's plenty of components packed inside of
the fish such as pressure sensors to actually detects what level of water
it's in other applications include seabed exploration for resources or
rescue jobs or for the underwater or leaking pipe leakage detection and
telecommunications cable detection as well thankfully this fish is keeping us
safe by keeping our water safe the robotic shark after creating the robotic
fish military scientists from the US Navy created a robot imitating the
fiercest sea predator which presents a sample of the shark robots like a real
fish this robot uses the tail to move and control its movements it's 1 meter
long and 62 centimeters wide it weighs up to 60 kilograms this robot moves
similar to real sharks so it is very difficult to distinguish it or at least
isolate it in the background of a real marine fauna it can swim high up and
dive deep such as a real shark can - an empty ship unnoticed and it can spy four
pair ships and arrange sabotages guys what do you think about it and how will
you use it let me know in the comments
number eight Festo era kuda the company Festo is
famous for its robotic animals and recently this company introduced a new
son the robot fish era kuda the era CUDA is pneumatically driven it follows its
biological models in terms of design shape and kinematics it has amazing
muscles which provides its s-shaped movements it allows copying the exact
movements of a real fish the device has liquid muscles a creation patented by
the company itself these muscles have elastic holes made of rubber as well as
aramid fiber inside this robot there is a swimming bladder a special cavity that
allows regulating the compressed air and setting the fish into motion to use this
mechanical fish for just 30 minutes you'll need 400 litres of compressed air
number 7 robotic octopus one of the most interesting robots is the octopus it was
made for investigating the deep bottom of the Seas and nowadays it is used
exactly for that silicon tentacles are moved by electronic engines and
accelerate the octopus up to 220 centimeters per second this robot is
equipped with camera and sound recording devices and it was used for the first
time in the sea to study French octopuses number 6
salamandra robotics this robot can move on the land and in the water it can
elegantly swim so most real reptiles the Swiss researchers developed a model of
salamander spinal cords and created a similar system to control the movements
of their salamander robot it receives electrical signals from a wireless
laptop that can tell it to switch from swimming to walking to changing speed or
changing direction number 5 soft robotic fish from MIT it looks like a fish moves
like a fish and even feels like a soft real fish the first self-contained
autonomous soft robot a fish that can execute an escape maneuver convulsing
its body to change direction in just 100 milliseconds or as quickly as a real
fish can their bodies are made out of soft silicon and they can bend and twist
because of that they are also inherently safe to be around and because of its
body's capability to bend and twist these robots are capable of very
complicated motion and very rapid agile maneuvers which pushes the envelope on
what machines can do today just like a biological fish this fish also uses the
escape maneuver or the sea turn to escape its prey this soft robot might be
more capable than hard robots in some tasks number four
besto aqua ray aqua ray is a remote-controlled fish with a water
hydraulic drive unit its form and kinematics are modeled on the movement
patterns of the manta ray the central drive and control unit of aqua ray takes
the form of a Festo fluidic muscle this is combined with the fin ray effect a
design based on the functionality autonomy of a fish's fin that makes it
possible to imitate the fin drive of the natural role model almost perfectly as
the aqua ray can be maneuvered extremely well it can also be operated as both
hydrostatic gliders with an active wing beat substantial energy savings that can
be achieved thanks to its shape and method of movement but aqua ray can be
used in wide-ranging areas of oceanography without disrupting the
natural environment number three
Festo aqua jelly jellyfish is one of the most beautiful and fascinating creations
in the sea and it's the world of robotics to here the company Festo
introduced an autonomous and an artificial jellyfish with an electric
propulsion system and in an intelligent mechanical system which can adopt to any
external changes it consists of a translucent hemisphere and eight
tentacles with LED laser bodies inside of this Bionic jellyfish we can find a
central motor of lithium ion batteries and a navigation block with two servo
motors to control the movements this robotic jellyfish is able to calculate
the power supply and when the battery is running out of power the device
automatically sends the information to the charging base located on the surface
and swims back up this mechanical jellyfish uses a radio band and when
being underwater it uses a system of infrared light for working the distance
of about 3 feet in the vicinity the jellyfish can perform an evasive
maneuver to these jellyfish are so impressive and so cool number two
aqua penguins like a real penguin the Aqua Penguins have an energy efficient
and streamlined shape their wing propulsion enables them to maneuver
autonomously in the tightest of spaces and even backwards aqua penguins can
find their way in the water and move independently with the aid of a 3d sonar
that mimics the real-life penguins they can communicate with the world around
them and with other Bionic penguins aqua penguins can swim in groups without
crashing by controlling depth pressure temperature and stability number one
Illume robot snake
meet Elle loom this mechanical snake is designed to perform maintenance and
repair operations on the seabed mainly on oil platforms this robotic sea snake
makes no difference in underwater worlds it is capable of replacing costly
amounts of underwater vehicles easily slipping into places where cumbersome
robots cannot reach it has cameras and sensors in both sides and it has a
modular design so that the different parts can be allocated for unique tasks
developers of a loom suggested it will not only reduce the cost of maintenance
under the sea but it can also provide an easy way of carrying out regular tasks
thank you for watching which one do you find the most
impressive and useful and why let me know in the comments if you are new here
