University of Tartu: Polymer fibre robot

History

2025: Product Announcement

Scientists at the University of Tartu have presented a robot that forms its body from polymer fibers, imitating the process of weaving webs. The device is able to adapt to various conditions, changing shape and moving on any surfaces, including Teflon, oily sponges and wax leaves of plants. The development was presented in March 2025.

According to TechxPlore, the robot forms its structure right in place using polymer fibers. This distinguishes it from traditional fixed-shape machines. During the experiments, the robot successfully overcame an obstacle course of sharp glass fragments, creating a strong path for a toy car. In another test, he "grew" a fiber grip and gently picked up a fragile flower.

The developers emphasize that the technology not only copies natural mechanisms, but uses their principles to create flexible solutions. The robot can adapt to the environment and transform it to its tasks. For example, in disaster zones, it is able to create temporary bridges over rubble, and in construction - to form structures on the spot without the use of heavy equipment.

The main advantage of the method is versatility. Polymer fibers can be attached to almost any surface, making the technology applicable under various conditions. During the experiments, the robot successfully fixed fibers on complex materials such as Teflon and wax-coated leaves.

The project combines knowledge from the fields of design, materials science and robotics. The developers note that their approach opens up new prospects for creating machines that can physically change their bodies depending on their tasks. This can be useful in rescue operations, construction and work in extreme conditions.^[1]
