When I was young, I saw in the textbook that the sunflowers would spend a meeting and follow the sun, so that there would be children running to watch. Now, if you let you go to the field, it will definitely be a torture. This machine sunflower developed by Kyushu University in Japan has infrared sensing function, which will follow your greeting direction. At the same time, the center of the flower is made of LED lights. When you wave to it, it will shine with its LED lights to say hello to you.
