The researchers have now invent a battery fluid can driver a robotic fish. which is call “machine blood” by researchers.
The software robot, which is about 40 cm long, is not equipp with a solid battery. But is driver by a dual-function liquid that stores both energy and the fins of the robot fish.
This approach allows the machine to store more energy in a smaller space and run longer. Without the need for bulky, complex battery packs.
Robert Shepherd, a robotic expert at Cornell University in Ithaca. New York, said that the innovation is an important step toward the development of autonomous robots. Autonomous robots can use without human labor. Complete the task with intervention or guidance.
The researchers described their machines in a paper published in the June 19 issue of Nature.
Keeping robots autonomous for a long time is a key challenge for robotics. Cecilia Laschi, a robotic expert at the Santa Ana Institute of Advanced Studies in Pisa. Italy, says that autonomous robots can have countless applications. Such as performing search and rescue missions and conducting deep-sea exploration.
But one of the main problems is energy storage.Where the robot has enough energy to perform the task without charging. Simply adding a battery increases the weight of the robot, causing it to require more energy to move itself.
New battery fluid can driver a robot fish
Shepherd’s research team did not use traditional hydraulic fluids—usually circulating around the machine to move their parts. But using a battery fluid (machine blood)to power the robotic fish. While also powering a pump to drive the fins and let the machine The fish swims.
Shepherd says that this method increases the energy stored in the robot. By 325% compared to robots with separate batteries and hydraulics. The team’s calculations show that the robot can work for 37 hours without charging.
Laschi also believes that this robotic fish is an important step towards autonomous robots. She said: “I think this idea is great and very creative.”
