Swiss Researchers have built a Robot Fish that can follow other Fish
Researchers chose the small fish due to their sudden bursts of movement
Swiss Researchers have built a Robot Fish that have an ability to imitate and mingle with zebrafish.
The reason for choosing small fish is their sudden bursts of movement.
The scientists studied the physical characteristics of zebrafish, including color, shape and stripe and their certain behaviors inside the school such as:
- Acceleration speed
- Linear velocity
- Distance between each individual fish inside the school
- Individual vibrations and motion
- The rhythm and pace at which zebrafish moves their tails.
The Fish Robot was put in in an aquarium with five different schools of zebrafish.
While robot fish is slightly bigger than a normal zebrafish, but it impersonates the zebrafish in many other ways.
As the swimming mechanism of a fish improved over the time, the fish accepted the robot into their school without any resistance.
With the robot was able to imitate the fish’s behavior, which persuaded them to change direction.
The core purpose of this study was to observe “whether animals will respond to robotic attempts to interact with them.”
“We created a kind of ‘secret agent’ that can infiltrate these schools of small fish,” says Frank Bonnet of the Swiss Federal Institute of Technology in Lausanne (EPFL).
According to Bonnet, using a robot interact with animals can help researchers to learn more about biology and robotics.
Bonnet believes this a huge step up from their last project in which they developed robots to imitate cockroaches.
