Bluebot: It is inspired by how schools of fish intuitively synchronise its movements, Harvard scientists have engineered miniature underwater robots capable of forming autonomous swarms.

Each and every robotic fish, referred as to as a Bluebot, that is provided with cameras and blue LED lights that sense the direction and distance of anothers inside water tanks.

They swim using flapping fins instead of propellers, which improves their efficiency and maneuverability compared to plain underwater drones…

Florian Berlinger said that, It is definitely useful for future applications — as an example a research mission within the open ocean where you wish to seek out people in distress and rescue them quickly, the lead author of a paper about the research that appeared in Science Robotics on evening of Wednesday.

Another applications such as they may involve environmental monitoring or inspecting infrastructure in it.

Existing underwater multi robot systems depend on individual robots communicating with one another over radio and transmitting their GPS positions.

The latest system moves closer to mimicking the natural behavior of fish, that shows complex, coordinated behavior with no following a frontrunner.

The 3D printed robots are about 10 centimetres i.e, 4 inches long, and their design was slightly inspired by Blue tang fish that are native to the coral reefs of the Indo-Pacific.

The robots use their “camera eyes” to detect other robots in their vision, then engage in self organising behavior, which include flashing their lights concurrently, arranging themselves in a circle, and comes around a target.

Berlinger described a test within which the robots were unfolded across a storage tank to hunt out a light-weight source.

When one in all the robots found the sunshine, it sent out a symptom to the others to assemble around, in a very demonstration of a search-and-rescue mission.

“Another researchers had reached resolute me already to handle my Bluebots as fish surrogates for biological studies on fish swimming and schooling,” said Berlinger, describing that the robot collectives may help everyone to learn a lots of about collective intelligence in nature.

He hopes to enhance the planning in order that it doesn’t require LEDs and might be used outside laboratory settings like in coral reefs.
