"Yun Xiao," a flapping robot bird developed by Northwestern Polytechnical University (NPU) in northwest China, was capable of flying for upmost 123 minutes continuously at one time, which was confirmed by a professional institute, said the university on Wednesday.
It marks a significant breakthrough in the flapping-wing bionic-bird drone development.
"Yun Xiao" was delivered by the NPU research team after more than 20 years of exploration and application in the field of bird flight mechanisms.
The winged drones, intimating the flying movements of birds, have the potential to achieve long-distance flight with strong mobility.
The drones can operate under temperatures from -10 to 40 degrees Celsius, and can stand level 4 winds, light rain and snow.
The NPU has developed other bionic drones with various features, obtaining more than 100 invention patents so far.
