This unhappy-looking fish is called a lionfish, and its appearance looks like the costumes of Peking Opera actors: the head is carved with a feather, the body is carrying a flag, and the appearance of a majestic samurai. In the eyes of most people, this fish is not only exotic, but also beautiful.
But just as Yin Susu said to Zhang Wujie, "The more beautiful a woman is, the more she will deceive people", there is also a law in nature, the more colorful the animal, the more likely it is to be dangerous. Lionfish is second only to stinging rays, even sharks are reluctant to go near lionfish, if humans accidentally pierce the skin by it, although not poisoned, the wound will be painful, swollen and inflamed. Moreover, it has few natural enemies, can eat 30 other species of fish in half an hour, and is also a crazy predator.
In the waters off Bermuda, lionfish as an exotic species have become a major problem, seriously threatening the local marine environment. Colin Angle, the founder of iRobot, learned about this problem when he traveled to Bermuda. Now, he's trying to solve it in a technical way.
Colin Angle, along with his wife, founded the nonprofit Robots in Service of the Environment and began making robots to catch lionfish. This robot is called the Guardian.
It dives into the water, knocks the lionfish unconscious, and receives it into its body. After catching a sufficient number of lionfish, the Guardian surfaced. The fish are then sold to various restaurants.
For cost reasons, Guardian is not fully automatic and requires human remote control. The development team is further simplifying the design and cutting the cost of manufacturing the robot, and Angle wants to keep the manufacturing cost under $1,000. They want to sell robots to fishing enthusiasts, or to professional fishing teams. Since the robot can be controlled remotely, gamification is also a good direction. "When you're sitting in your office and want to do something good, you can catch lionfish on your iPad." Angle says.
To be honest, Egg Egg doesn't really care much about Guardian, egg egg first thought of following the American bullfrog, Danish oyster, Mexican crayfish, Bermuda lionfish is calling us again! It is said that lionfish "tastes very good, the meat is tender and juicy, and the processing method is simple", which is estimated to be much better than the Fujian people!
