Pictures must credit: Korea Institute of Machinery and Materials A wheel that can ride over obstacles like stairs or rocks by adjusting its stiffness in real time, has been developed for the first time in the world. It can operate as a rigid, circular wheel in a regular driving mode and then switch to a soft, deformable state when rolling over obstacles, depending on the height and shape of those obstacles. The technology is expected to find wide applications in any vehicle where overcoming terrain obstacles is essential. That could mean anything from wheelchairs to off-road vehicles. The team also believes they could be fitted to robots, both bipedal and four legged kinds. Thewheel was created by engineers at the Korea Institute of Machinery and Materials, known as KIMM, who were inspired by the surface tension of a liquid droplet. It works by simply changing the surface tension without having to use complex machinery or sensors. There already have been technologies for designing the inside of wheels as flexible structures, like non-pneumatic tyres. However, the limitation of these conventional technologies is that the wheels are continuously deformed even when driving on flat surfaces, which hinders driving efficiency and stability and generates noise. In contrast the wheel developed by the KIMM research team can be adjusted between a rigid state for fast movement on flat ground and a soft, deformable state for overcoming obstacles.
