A few days ago I introduced the bionic robot ant. This time I introduce another masterpiece of the Festo company, the bionic mechanical butterfly. This butterfly only weighs 32 grams, has a wingspan of 50cm, and only carries It has a sensor and a mechanical structure that flaps its wings, and its flight path is completed with the help of several cameras on the field. This design can minimize the burden on the processor and keep the butterfly body as light as possible. Most importantly, it can control the flight of swarms of mechanical butterflies.
