In everyday mobility, obstacles like rocks, stairs, and uneven terrain present significant challenges. The need for a solution that can adapt to these varying conditions has led the Korea Institute of Machinery and Materials to develop a wheel that adjusts its stiffness in real-time. This innovation is inspired by the surface tension of liquid droplets—where the force pulling the liquid molecules together allows for a stable and adaptable form.
Similarly, the wheel's stiffness changes based on the terrain it encounters, switching from a rigid state for smooth surfaces to a flexible, deformable state for obstacles. By mimicking this principle, the wheel can smoothly navigate over rocks or climb stairs with ease. This technology makes the wheel versatile enough for use in various mobility devices and vehicles, providing a smoother ride and enhanced adaptability across different environments.
This adaptable technology opens up new possibilities for mobility, allowing devices like wheelchairs, personal transport vehicles, and even robotic systems to navigate challenging terrains with greater ease. By providing real-time adjustments, it offers a more efficient and comfortable ride, reducing the effort required to overcome obstacles. Whether it’s climbing stairs, crossing rough paths, or simply moving across a flat surface, the wheel's ability to change its stiffness ensures users can move with confidence and stability in various environments.
