Researchers from Harvard University have 3D printed a school of soft robotic fish that are capable of swimming in complex patterns without the aid of Wi-Fi or GPS.
Inspired by the distinctive reef-dwelling surgeonfish, the team’s ‘Bluebots’ feature four fins for precision navigation, and a system of LEDs and cameras that enable them to swarm without colliding. The self-sufficiency of the tiny bots could make them ideal for ecological monitoring applications, in areas that wouldn’t otherwise be accessible to humans.
“Just by observing how far or close they are in a picture, they know how far or close the robot must be in the real world. That’s the trick we play here,” the study’s lead author Florian Berlinger told Wired.
