Harvard scientists
engineered tiny underwater robots that independently swarms and who are inspired
by fish schools.
The blue bot is termed for
these robotic fish are provided with the cameras and blue LED lights that
can six sense the directions and the distance from each other in the water
tanks.
Rather than the
propellers these fishes swim using the flapping fins, this also helps in the
efficiency. They swim using flapping fins rather than propellers, which
improves their efficiency and immotility which are far better than the drones
which are underwater.
For the future
applications it will be really helpful. Like easily you can find people and
rescue them, said Florian Berlinger. The older system which is an existing
underwater multi-robot system relies on every single robot that communicates
with each other by the use of radio and transmitting their GPS positions. But
the new system now moves close to take off the fish’s natural behavior that
shows compounded and organized behavior without following ahead.
The designs for these 3D printed robots
was slightly inspired by Blue tang fish that belongs to coral reefs of the Indo-Pacific
and these are about 10 centimeters (4 inches) long.
In order to detect other robot fishes, they use camera “eyes” in their peripheral vision. They are involved in self-organizing behavior. They perform many works like they gathered themselves
around the target, they simultaneously flash their lights, also in a circle
they arrange themselves.
Berlinger already talked about this
test and explained very well that the robot together helping us to learn about
intelligence in the environment. Also, he tells about improving the designs so that
LEDs will not be used.
