Recently researchers at the University of Zurich are adding a new member to the drone ( 无人机） family. Unlike most drones whose application is to make selfies ( 自拍)or transport something, this drone was built with first aid workers and rescue efforts in mind. Disaster sites are rarely logical shapes and sizes. So having a drone that could change its shape and size to fit through tight spaces on the fly could prove extremely valuable.
As is often the case in experimental robotic projects, researchers met some technical setbacks ( 挫 折 )at the beginning. The airplane mode of the existing aircraft such as passenger planes，helicopters and the common drones couldn’t meet the demand of different environmental features. Eventually, they turned to animals for inspiration— specifically how some birds can fold their wings to fly through narrow passages.
What makes it distinguishing is that when faced with a narrow passage it can change into an H shape. Or it can shrink itself into an O shape, arms folded into its body. And if that wasn’t enough, it can also transform into a T shape, allowing an onboard camera mounted (镶嵌)on the central frame to get as close as possible to its focal object.
While the working concept model is impressive, the researchers aren't done with the folding drone yet. They want to improve the structure of the drone so that it can fully fold in three dimensions, offering even more shapes. And they want to create full auto-operation—a drone that looks at the shifting terrain(地形）in，for example, an apartment building partly destroyed by an earthquake and changes its shape to meet its current needs.
Researchers say their final goal is to give the drone a high-level instruction such as “enter that building, inspect every room and come back and let it figure out by itself how to do it”. Therefore, it’s reasonable to hope the new drone will play an important supporting role in disaster rescue.
