A new technology promises to revolutionize urban mobility: scientists have developed a new wheel capable of climbing stairs, eliminating barriers and bringing a futuristic solution to transportation in cities.
Technological innovation never ceases to amaze, and this time Korean scientists have come up with a solution that could transform the way we move around in our daily lives. They have developed a new wheel capable of climbing stairs and overcoming obstacles, a technology that promises to revolutionize urban mobility. This invention, called a “metamorphic wheel,” adjusts its rigidity in real time and was inspired by none other than the behavior of the surface tension of a drop of liquid.
The wheel that adapts to the terrain: How the new mobility technology works
The wheel developed by Korean scientists Korea Institute of Machinery and Materials (KIMM) has a revolutionary concept that distinguishes it from any other model on the market. The secret lies in the wheel's ability to change its stiffness according to terrain conditions.
On flat surfaces, it acts like a traditional wheel, offering speed and stability. However, when it encounters obstacles, such as rocks or stairs, the wheel transforms, becoming soft and flexible, which allows it to overcome obstacles that would be insurmountable for ordinary wheels.

This dynamic stiffness adjustment is the big difference in this new wheel capable of climbing stairs. According to the Professor Dong Park, one of the main people responsible for the research, the technology was created to solve the limitations of traditional wheels, which normally cannot handle uneven surfaces.
The metamorphic wheel promises to open up new possibilities for urban mobility, including wheelchairs, mobile robots and personal transportation devices.
The inspiration behind the stair-climbing wheel
What makes this new wheel so interesting is the way it was inspired. The engineers behind the design used the surface tension of liquid droplets to create a wheel with variable stiffness.
Surface tension, which keeps a water droplet in a spherical shape, has been adapted to act on “smart” chain links in the wheel, allowing it to adjust itself without the need for complex machines, actuators or sensors. This means that the wheel is able to automatically change its behavior depending on the type of obstacle it encounters along the way.
The flexible structure of the Metamorphic Wheel adapts to the terrain, using a system of spokes that control the tension of the chain around the rim of the wheel. When the spokes tension the chain, the wheel takes on a rigid shape, perfect for flat surfaces.
But when faced with obstacles, the spokes loosen the chain, allowing the wheel to deform and pass over barriers such as steps or stones, making it a wheel capable of climbing stairs up to 18 centimeters high.
Practical applications of the metamorphic wheel: a leap into the future of mobility
This new wheel not only solves an age-old problem – the difficulty of climbing obstacles in the path – but also opens the door to a wide range of applications. One of the first implementations of the stair-climbing wheel was on a wheelchair, which proved to be extremely efficient in tests.
The chair equipped with this new wheel was able to move smoothly and stably regardless of the terrain, and had its maneuverability improved, especially in small and obstacle-filled spaces.
Furthermore, the morphing wheel is significantly more efficient than mobile robot technologies that rely on legs to move. While these robots can successfully overcome obstacles, they tend to be inefficient on flat terrain and generate tremors during movement. The new wheel offers the best of both worlds: the ability to overcome obstacles like quadrupedal or bipedal robots, while maintaining the movement efficiency of a traditional wheel.
Professor Sung-Hyuk Song, who is also part of the project, highlighted that this metamorphic wheel is an important advance for mobility, as it allows people to overcome obstacles with ease, without sacrificing speed and stability on flat terrain. The metamorphic wheel is undoubtedly an important step towards the creation of new urban mobility devices that could improve the lives of many people.
Challenges and perspectives: the future of this new technology
Despite being a promising innovation, the large-scale implementation of the stair-climbing wheel still faces some challenges. The main one is the modularization process, that is, adapting the wheel so that it can be applied to different mobility devices. However, the team of Korean scientists has already developed a miniaturized version of the technology, which can be easily integrated into a wide range of mobile systems.
With modularization, the metamorphic wheel could be used not only in wheelchairs, but also in mobile robots, urban vehicles, and other personal transportation devices. The versatility of this new wheel opens up a range of possibilities for the future of mobility, especially in urban areas where obstacles such as stairs and uneven sidewalks are common.
Furthermore, the stair-climbing wheel has the potential to improve accessibility in urban areas, making life easier for people with reduced mobility. For those who rely on wheelchairs or other mobility devices, this innovation could represent a true revolution.
The new wheel that promises to transform urban mobility
The stair-climbing wheel developed by Korean scientists represents a significant technological breakthrough that could revolutionize the future of urban mobility. By automatically adapting to terrain and overcoming obstacles that previously seemed insurmountable, this new wheel paves the way for more efficient and affordable devices.
From use in wheelchairs to robots urban furniture and vehicles, the applications of the metamorphic wheel are vast and promising.
Its design inspired by the surface tension of liquids and the ability to adjust stiffness in real time ensure that this technology will be a key part of the next generation of mobility devices.
With the growing demand for more efficient and affordable solutions for urban mobility, the stair-climbing wheel emerges as an innovative and practical answer to the challenges of transportation in urban environments. This invention certainly has everything to transform the future of mobility and provide a more accessible world for everyone.

There can be no clay. This idea has been around for years. It's nothing new.
