IT Home reported on May 7 that the official account of Northwestern Polytechnical University released a blog post yesterday, announcing a new breakthrough in the imitation of the "Firefly" communication drone. The Institute of Optoelectronics and Intelligence of the university imitates the communication mode of fireflies, and uses optical communication and intelligent information processing technologies to realize the information transmission between drones under electromagnetic interference.

IT Home quoted the official account as reporting that the flash of the firefly's tail is their way of encrypted communication, and they convey signals such as distinguishing the same kind, alerting to danger, and guiding the direction through a unique luminous mode and frequency.

Imitation "Firefly" communication UAV information interaction process

Under the leadership of Professor Li Xuelong, the scientific research team researched and proposed an imitation "firefly" communication drone, which provides an innovative solution for the development of UAV clusters: through the lighting equipment on the UAV to send light signals, and in another UAV to use photoelectric sensors to capture light signals and conduct intelligent analysis, to achieve short-distance information transmission like firefly flickering communication, and complete the cooperative flight based on optical links between UAVs.

Because the transmission of optical signals is not affected by the electromagnetic environment, there will be no mutual modulation and mutual interference, and the anti-interference ability is strong. In addition, it has a low transmit power and produces almost no heat, making it suitable for carrying small UAVs with limited energy.
