The United States Naval Research Office has recently developed a "machine jellyfish" that can be used to monitor surface ships and submarines and detect chemical spills.
According to foreign media reports, the US Naval Research Office has recently developed a "machine jellyfish" that can be used to monitor surface ships and submarines, detect chemical spills, and monitor the movement of migratory fish.
These machine jellyfish are connected by thin wires made of bio-inductive memory alloys. When these metal wires are heated, they shrink like muscle tissue.
According to Alex Villanueva, a graduate student at the Virginia Polytechnic Institute in Virginia, the initial model of the jellyfish in the machine does not fully simulate the jellyfish's free movement. It only fluctuates or does not move. It does not Actually swim to any area.
By studying how the jellyfish moved, Villanueva later modified the mechanical structure of the jellyfish in the machine to more realistically simulate the jellyfish. It is reported that the jellyfish in the real state rely on the contraction and deformation of the body bell structure to form the propulsive force in the water.
Veranueva said: “When we started this kind of machine jellyfish, they could swim true and were therefore favored and loved by biologists. They called the machine jellyfish very close to the natural jellyfish.†At present, he will be the machine The jellyfish research report was published on November 22 at the 2011 Annual Meeting of the Department of Liquid Dynamics of the American Physical Society in Boston, USA.
At present, Villanueva devotes itself to improving the fluid mechanics of this kind of machine jellyfish so that it can swim more fluently in the water and make full use of energy like natural jellyfish. In addition, he is working on the development of a 5-foot diameter machine jellyfish prototype with the jellyfish jellyfish prototype.
