Imagine a submersible robot gliding silently through the depths like an ancient squid-like creature! Researchers have created such a device called Robonautulus, taking inspiration directly from these fascinating sea creatures.

How Does It Work?

Robonautulus moves by ejecting jets of water, mimicking the anatomical structure of prehistoric cephalopods. To achieve this, engineers employed special dielectric membranes that can flex under electrical current, replicating the pulsating contractions typical of these marine animals' bodies.

Why Choose Cephalopods?

These creatures stand out for their ability to swiftly navigate through water, changing direction and speed instantly thanks to their flexible body rhythmically contracting and expanding. However, reproducing such motion mechanically proved challenging, as most previous solutions relied on cumbersome hydraulic systems or rigid motors.

Key Features of Design:

- A completely soft body made via 3D printing.
- An elastic membrane replaces traditional motors, ensuring smooth movement.
- Sensor suite including cameras, temperature, and salinity detectors.

This design makes Robonautulus ideal for exploring fragile marine ecosystems, where conventional devices could cause harm.

Researchers plan further enhancements, incorporating autonomous navigation and enhanced orientation systems. They believe technologies like these open up new possibilities for underwater research, environmental monitoring, and even rescue operations.

Thus, studying ancient forms of life, scientists offer us a glimpse into future robotic assistants: silent, gentle, and effective companions capable of gently exploring Earth’s oceans.
