According to foreign media reports, bionic technology is an important way to create future machines. Nature's species have evolved over millions of years and gradually become adaptive to the environment. Researchers from Northwestern University are currently developing a new type of organism. Underwater robots use biomimetic principles derived from Amazon's electric fish. The robot they are developing can perform tasks in a completely dark environment, replacing humans into dangerous waters, such as swimming around shipwrecks and even deepening shipwrecks. Internal exploration.
Prof. Malcolm McKeeper believes that we do not have an underwater robot that can perform missions under real danger. For example, after a cruise ship sinks, it is very dangerous to send divers to the waters around the shipwreck. The seawater here is generally in very high visibility. Poor state, there may be dangerous whirlpools in the water. But we can learn some knowledge from electric fish. The electric fish do not use its visual system to prey on the Amazon River, and it has incredible precision. Researchers at Northwestern University have deciphered the sensory and motor systems of electric fish through years of research. The neurons distributed along the spine can feel the weak voltage changes caused by prey entering the water. Although the perturbation is very weak, it is enough to make electricity. Fish finds their existence.
The electric fish has evolved a complex sensory system in which its sensory nerves can connect the entire body so that the electric fish can tell itself about the situation in the environment and can feel the slight change in voltage in all directions. This is like a whole body cloth. Full sensor platform, any one direction of the disturbance will be detected by the sensor. In Professor McKover’s laboratory, scientists are studying the construction of omnidirectional sensors that can be used on tank robots and have the ability to sense the surrounding situation.
At the same time, researchers seem to be hoping to replicate the special "propulsion" techniques used on electric fish. Professor Malcolm McKiefer believes that the construction of the propulsion system needs to give an accurate mathematical relationship between frequency and amplitude. At present, researchers at Northwestern Laboratories in the United States are developing artificial sensory systems and have given advanced athletic performance. (List/Compilation)
