Most of us have probably eaten fish,
and maybe even had a pet goldfish.
But few of us have seen a robotic fish.
The University of Essex has developed a robotic fish
in order to fill a very special need.
These fish keep us safe by keeping our water safe.
Wondering how they do this?
Watch this video to find out.
Fish with in-built chips.
It's beautiful.
A world first robotic fish with sensor-based controls
and autonomous navigation capabilities.
For you and me, that means that they can swim around the tanks safely,
without clunking into the glass.
They're brilliant. They're cool, they're neat, they're wicked, they're massive, they're powerful!
The fish aim to swim at the same speed as tuna,
have the acceleration of a pike, and the navigation skills of an eel.
And it seems, sunglasses for eyes.
They've been developed at the University of Essex.
The idea is because we see the real fish has evolved for thousands of years,
and they have natural swimming behaviors.
So we think we do the same, with the robots.
The technology could one day be put to use on the sea bed,
for example finding leaks in oil pipe lines, and detecting mines.
But for now, these little swimmers can be found at the London Aquarium.
