We have all seen at least one or two robotic fish by now, such as this robotic fish that was released in Spanish waters to search for pollution.
Well, now we have a robotic fish that can actually lead a school of fish. This robotic fish was developed by Maurizio Porfiri, an assistant professor at the Polytechnic Institute of New York University.
Shown here is Maurizio with the robot that looks like a black heart. Using ionic polymers, the robot acts like a muscle when a current or voltage is applied. The robotic fish swims silently and is slightly larger than the other fish, allowing it to lead them. Some day this technology could be used to lead the fish to safety in case of danger.
We also wonder what this may someday means for commercial fishing. Will catching fish be as easy as dropping a robot in the water and watching all the fish swim into your net?
