Scientists have created a robot with artificial blood fish

In an effort to make robots more alive, scientists from Cornell University and the University

Pennsylvania created a soft robotic lionfish and filled it with “blood”.

Better than a regular robot

While typical robots are equippedcumbersome details like a battery or different mechanisms, the newly developed lionfish has a unique circulatory system. "Blood" contains an electrolyte solution that works as a hydraulic fluid and energy storage device. This allows the robot to swim for 36 hours - eight times longer than a similar battery-powered robot.

Researchers say that nothing like anybodyI have not done it before: this is the first experiment in which the transfer of hydraulic force, energy accumulation and activation in a single multi-purpose system were combined. The development will most likely be used to extend the functionality of soft robots. In addition, it can be used in all machines requiring fluid. For example, “smart blood” can increase the power of electric vehicles and airplanes. And of course, it makes us one step closer to truly realistic robots.
