Harvard University uses LED lights to develop living robotic fish

Harvard University researchers were inspired by schools of fish and created a set of fish-shaped underwater robotic fish that can navigate autonomously and find each other, and cooperate on tasks. These bionic robotic fish are equipped with two cameras and three blue LED lights, which can sense the direction and distance of other fish in the environment.

These robots are 3D printed into the shape of a fish, using fins instead of propellers, cameras instead of eyes, and lit LED lights to mimic the bioluminescence in nature, just like the way some fish and insects send signals. The LED pulse will be changed and adjusted according to the position of each robotic fish and the knowledge of the "neighbors".

Using the simple senses of the camera and the front light sensor, basic swimming movements and LED lights, the robotic fish will automatically organize its own group swimming behavior and establish a simple "milling" mode, when a new robotic fish is put in from any angle At the same time, they can adapt.

These robotic fish can also complete simple tasks together, such as finding things. When giving this group of robotic fish a task, let them find a red LED in the water tank. Robot fish.

In addition, these robotic fish can also safely approach coral reefs and other natural features without disturbing marine life, monitor their health, or look for specific objects that their camera eyes can detect, and can be on docks and ships. Wandering below, inspecting the hull, it can even play a role in search and rescue.
