An Ultra-Flexible Autonomous Robot for Abyss Detection

To detect seabeds, researchers have developed a soft robot. Thanks to a distributed electronic system and flexible actuators, he was able to swim to a depth of more than three kilometers.

To detect seabeds, robots and other vehicles Submarines The face is designed with extra thick metal shells The expression. The deeper they have to go, the heavier these devices become. A new approach, Published in the magazine NatureCalls on Soft robotics To create a more compact and flexible robot. It is capable of moving autonomously at a depth of 3,224 meters.

Researchers take inspiration from this Liparida, slugfish that live in the abyss, and have no external defenses to resist pressure. Electronic elements were separated by distributing them Robot body Before wrapping them Silicon. It reduces Tension Due to the pressure at the interface between the components.

A soft body with “muscles”

The robot moves forward with its two wings. For “muscle”, researchers used elastomers Dielectric, a Content Dull Electric power. A prototype of this system has been successfully tested at a depth of about 11 km. Mariana Trench, While the entire robot was able to swim unsupported to a depth of more than three kilometers in the South China Sea.

Despite the success of this first edition RobotResearchers still need to improve it to compete with rigid robots. with Speed 5.19 centimeters per second (0.19 km / h), it is still quite slow. In addition, it is not resistant to currents and can be easily carried away. However, this robot is much cheaper to produce, and once proven can facilitate the discovery of seabeds.
