amazing robot which really exist
As for butterflies-robots. The weight of each butterfly is only 32 grams, this includes two servos, a pair of small batteries, and a laser-made casing. After one charging that lasts fifteen minutes, butterflies will be able to flutter for about 4 minutes. And their flight looks very impressive. There’re not just butterflies, but a whole system that consists of ten high-speed infrared cameras installed in a room where butterflies fly. They track the infrared markers installed on the robots, transmitting data in real time to the central computer; so that’s how coordination of butterflies is going in the space. You can hardly distinguish these bionic butterflies from the real ones in the room where they fly.
