Because many times, we can see some stairs on the road. For the old people, climbing stairs is a dangerous thing, and they will fall down if they are not careful, and their bones are very fragile, which poses a certain threat to their lives and health. At such a time, inventing an intelligent wheelchair is a gospel.
such an invention finally appeared after two years. Many people here also express their deep support for it. It is also a good representative for such an invention. For this wheelchair, it can also intelligently identify the existence of stairs. When it hits the stairs again, the front part of the car leans back to keep the rider in balance with the ground, and then it starts driving safely. In this way, when it encounters stairs or obstacles, the front part of the track climbs and rises first. Because of the segmented design of the crawler, it can be stuck on the stairs at different angles, and the whole is very stable. For such a thing, it is also a good solution to the problem that they are inconvenient to climb the stairs, and it is also a good invention for them.
