Scientists at the Institute of Technology, University of Tartu, have created a new kind of robot that can spin its own body parts and pathways, just like a spider spinning its web.
This means that instead of having a fixed shape, these robots can create the structures they need in the moment, adapting to different environments as required.
The robot spins fine fibers from a special heated liquid that quickly cools into strong, flexible strands.
These fibers can form tools, pathways, or even bridges.
Unlike traditional robots with rigid designs, this machine reshapes itself depending on the situation, making it perfect for rough and unpredictable environments.
In a series of tests, researchers showed how this spinning robot can overcome challenges.
In one experiment, it built a bridge across a debris field, allowing movement over sharp glass shards and soft feathers alike. In another test, it created a delicate fiber limb to gently pick up a fragile flower without damaging it.
This technology can also attach itself to almost any surface, including slippery Teflon, oily sponges, and waxy plant leaves.
It works by combining physical adhesion and mechanical entanglement—just like how spiderwebs naturally stick to different surfaces.
**Inspired by Nature, But Smarter**
Lead researcher Marie Vihmar explains that their design is inspired by spiders but is even more flexible.
Unlike spiders, which follow strict biological rules, these robots can spin their structures in a way that best fits the situation, making them incredibly adaptable.
This breakthrough is possible thanks to a team combining different expertise. Vihmar, with a background in design, focuses on creative shapes and functionality, while senior scientist Indrek Must ensures the materials and technology work efficiently.
This research could change the way robots interact with the world. Instead of building stiff machines that struggle in difficult environments, these robots can create their own solutions on the spot.
This could be useful in disaster rescue, construction, and exploring unknown terrains.
Rather than forcing the environment to fit a rigid machine, this technology allows robots to blend into their surroundings and even transform them when needed.
By taking inspiration from nature, scientists are paving the way for a future where robots are no longer just tools but living, changing structures that adapt as they go.
