A Robotic Spy among the Fish


Researchers at EPFL have developed a miniature
robot that can integrate perfectly into schools of zebrafish. This robot is a kind of ‘secret agent’
that can infiltrate the schools of small fish. This Robot can swim with fish, learn how they
communicate with each other and make them change direction or come together. The robot is able to not only influence the
fish’s behavior, but also adapt its own behavior by learning how to communicate and
move like they do. As a result, the robot’s swimming mechanism
– initially designed with the help of biologists – gradually improved as the robot spent
more time with the fish. The team tested their robot in different aquariums. The fish accepted the robot into their schools
without any problem. And the robot was also able to mimic the fish’s
behavior, prompting them to change direction or swim from one room to another.
