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 parts like batteries or various mechanisms, the newly developed lionfish has a unique circulatory system. The “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 nothing like anyonenever done before: this is the first experiment to combine hydraulic force transmission, energy storage and actuation in one multi-purpose system. The development will most likely be used to expand the functionality of soft robots. In addition, it can find application in all machines that require fluid. For example, smart blood can improve the power of electric vehicles and airplanes. And of course, this brings us one step closer to truly realistic robots.
