Эта лестница сама помогает подниматься и спускаться по ней (видео) Engineers have always surprised with their unusual solutions to facilitate everyday life. Specialists from the Georgia Institute of Technology and their colleagues at Emory University decided that some segments of the population, for example, older people and people with disabilities, should be provided with independent assistance in climbing stairs and therefore invented an energy-efficient “smart” staircase that helps them walk. Эта лестница сама помогает подниматься и спускаться по ней (видео) The essence of the invention lies in special steps having integrated springs. When a person descends, then the steps fall under the weight of the walker. This saves energy and reduces load by almost 22 percent. When you need to go up, the steps go up, pushing the foot of the walker, and this reduces the load on the knees by almost 38 percent. Yes, and go, of course, easier. The inventors used pressure sensors. But there are nuances. The system works when only one person goes up the stairs.
