Brief content: American scientists recently developed a bionic "machine fish." When that happens, robotic fish will be sent to all corners of the water world to perform tasks, monitor water pollution and volcanic activity on the seabed, and even be able to track enemy submarines.

American scientists have recently developed a bionic "machine fish." Although they do not resemble real fish but are elaborately designed mechanical devices, they can swim and move like fish.

New robotic fish

The National Broadcasting Corporation website reported that Christie Morganson of the University of Washington was a teaching assistant in the Department of Aerospace and her scientific team successfully created a bionic robotic fish. Although they are different from real fish, they can swim and move like fish.

Currently, the Morgans team has created three robotic fish that currently "live" in the pool of the laboratory. Prior to the development of the robotic fish must emerge once every once in a while, in order to send and receive new information, just as the fish surfaced breathing oxygen.

And Morganson's robotic fish can send electronic signals underwater and complete the transmission of data through pressure waves. Therefore, they can communicate with each other underwater, and can even accomplish some actions together, such as assembly and dissolution.

Inspired by nature

In a television interview, Morganson said that she developed robotic fish inspired by nature. She called it "biological inspiration." She borrowed the most exquisite results from Nature, the supreme creator.

In order to enable robotic fish to communicate underwater like real fish, Morganson worked closely with ichthyologist Julia Parish to conduct a careful and detailed study of the fish's communication methods before finally solving it with pressure waves. This problem.

Morganson and team members domesticated a group of fish, and trained them to get food in the food area after being stimulated by the outside world. The study found that not all fish understand the schedule of work, but once a small portion of the fish realize that the lunch time is up, they can communicate with other fish to know this information.

So, can robotic fish also communicate like fish? Morganson answered this affirmatively. The robotic fish developed by her team were able to communicate with each other underwater and receive tasks such as assembly and dissolution.

Conquering the future of the water world?

Morganson believes that robotic fish can conquer the future water world. She said that one day in the future, her team will produce hundreds of robotic fish. They are subdivided into different categories, and they can accomplish different tasks as they expand.

When that happens, robotic fish will be sent to all corners of the water world to perform tasks, monitor water pollution and volcanic activity on the seabed, and even be able to track enemy submarines.

However, in order for the day to come, Morganson and her team have to overcome many difficulties. First of all, due to the limitation of the experimental pool, the deepest depth that the robotic fish have ever snorkeled is only 8 feet (about 2.5 meters). Above this depth, it will seep or even break, and it will not work at all. Second, to allow robotic fish to work deeper underwater, they must be equipped with better power devices rather than batteries that are used today. In addition, the current robotic fish search target takes a long time, because it requires more complicated information exchange, and the speed of computer operation limits the robotic fish's activity capability.

In the coming weeks, the Morganson team will simply train robotic fish to track their toy sharks in the pool.

Concrete Vibrator And Vibrator Poker

The working principle of the concrete vibrator is to use high-frequency vibration to remove air bubbles and voids in the concrete, make the concrete more compact, and improve the quality and strength of the concrete.
