Inspired by Myosin, Ultrafine Robot Developed in South Korea Combines Strength and Flexibility for Surgical and Industrial Tasks in Tight Spaces
Scientists at Pohang University of Science and Technology in South Korea have developed a robot as thin as paper but capable of generating great strength.
The study, published in July in the journal Nature Communications, points out that the technology could have medical and industrial applications.
Inspiration from Human Biology
Most importantly, the project is inspired by the protein myosin, responsible for much of the movement in the human body, such as the transport of organelles and muscle contraction.

Students from a technical school in Pernambuco created a filter made of pine cone scales and activated charcoal that removes the toxicity of manipueira, the residue generated in cassava flour mills that has been contaminating rivers in the Northeastern semi-arid region for decades, and the Filtropinha project was awarded by Instituto Alana with R$ 12,000 and a trip to COP30, in November 2025.

It took us 30 years to confirm 6,000 exoplanets, but a single project using the Transiting Exoplanet Survey Satellite has already found over 10,000 candidates in just one year by analyzing 83 million stars with artificial intelligence.
Using this reference, the researchers created a robot with protrusions on the surface that allow it to attach to different materials and move in multiple directions.
Despite its minimal thickness, the device has enough strength to perform complex tasks. In the shape of a blade, it contains dozens of small air chambers stacked in three dimensions and a network of pneumatic circuits.
This structure enables movement even when bent, moving “like a caterpillar” using only the help of the protrusions.
Precise Movements and Versatility of the Robot
According to the study, the robot can move in six different directions, varying speed and distance according to the sequence of pressure applied. This enables maneuvers in tight spaces and precise handling of objects.
Traditional robotic devices, made of rigid metal components, offer resistance but have limitations in executing delicate movements or operating in narrow areas.
The new model combines strength and flexibility, expanding its potential use.
Possibilities in Medicine and Industry
Additionally, the robot can remove obstacles in narrow pipelines, manually manipulate objects, or transport underwater items.
In medicine, the demand for equipment capable of performing delicate interventions is growing. The South Korean robot, with precision similar to that of human fingers, can be inserted into the body through small openings, making it a valuable tool in minimally invasive surgeries.
The researchers emphasize that this technology allows for safe manipulation in sensitive areas without compromising nearby structures.
This feature can be crucial in complex procedures, where millimeters make a difference.
Ultrafine Robot: Basis for New Applications
To expand the possibilities of use, the scientists also developed a mathematical model that predicts the movements of the robot.
This prediction provides parameters for future adaptations, allowing the creation of specific versions for different sectors.
“We hope this technology will be applied in various fields, including surgical robots, collaborative robots in industrial settings, and exploration environments,” said Keehoon Kim, one of the study’s authors, to the university’s portal.
Thus, the paper-thin robot presents itself as a promising advancement, combining science, engineering, and biological inspiration to tackle challenges in critical areas.
