A analysis group in South Korea has developed a soft robot named Octoid that may mimic the motion and conduct of an octopus in its pure habitat. The robotic’s “triple-in-one” system allows it to shift colours, transfer and seize prey in a method that’s fascinatingly just like the aquatic animal.
Whereas the scientific world has been engaged on modeling robots after octopuses for over a decade, that is the primary time scientists have been in a position to mix the best way an octopus strikes and camouflages itself right into a single robotic.
Octoid was constructed by researchers from the Korea Institute of Science and Expertise, led by a scientist named Dae-Yoon Kim.
“We goal to broaden this expertise into the event of clever tender machines, corresponding to self-aware, reflexive, and learning-based tender robots,” Kim mentioned in an announcement on Thursday.

Colourful crystals
The Octoid legs camouflaging themselves just like the octopus pictured above.
The core materials used for Octoid is known as photonic crystal polymer. It is a nanostructured material that may do fascinating issues when gentle passes by means of it. By separating and reflecting particular wavelengths of sunshine, this type of polymer can show good colours inside its construction.
In the present day, photonic crystal polymers have many real-world applications, like high-tech sensors, distant communication and optical computing. However utilizing this materials to make tender robots continues to be a reasonably new and rising subject inside robotics.
The researchers used the polymers to present the robotic a particular construction that has the flexibility to maneuver in a tender and versatile method whereas it adjustments colours. The group was in a position to management the robotic utilizing electrical alerts that created microscopic contraction and growth, which made Octoid change from blue to inexperienced to purple.
Aquatic robotics
The octopus has a singular physique that has interested scientists for years. We have seen robots that transfer just like the tentacles of an octopus from a wide range of labs and corporations. It is not solely octopuses, both; sea creatures appear to capture the creativeness of roboticists everywhere in the world.
The group behind Octoid says the robotic showcases new potentialities for biomimetic tender robotics expertise. They are saying that the tech displayed in Octoid’s physique has the potential to assist in industries like deep-sea rescue, marine ecology monitoring, and hospital robots to assist folks attain farther, in addition to army functions.
“By means of this analysis, we’ve secured supplies for tender robots that may be utilized to varied fields, together with autonomous adaptive robots, army camouflage methods, marine exploration robots and medical micro-robots,” Kim mentioned.
The paper was initially printed on Oct. 15, 2025, in Superior Useful Supplies.
