"bang Dang!"

your UAV unfortunately encountered an air crash during its flight. It lost its balance due to wing damage and landed hard on the concrete ground

many parts of the UAV at the scene of the accident were cracked and missing corners, exposing a large number of damaged complex components. Looking at this pool of expensive drone remains, you suddenly feel cool and realize:

this month's salary is -50%

it's a pity that you didn't buy a drone produced by the Federal Polytechnic Institute of Lausanne (EPFL)

hybrid origami UAV

epfl's intelligent system laboratory has invented a kind of UAV called "hybrid origami UAV", which means that it can bend its "arm" like origami in case of collision, so as to prevent the parts of the UAV from being damaged

the hybrid origami UAV is inspired by insect wings, which are rigid in the load-bearing part, but flexible in the joints. The wings are composed of inner arms made of stretched membrane, which imitate the soft elasticity of joints and are clamped between a pair of hard plates

firmly focus on the main line of supply side structural reform

therefore, if insects want to fly, they can spread their wings and keep the thematic investment opportunity arm brought by the gradual promotion of relevant listed companies with new material technology reserves and the industrialization of new materials in a rigid state; If the insect wants to give advice, it can exert force, separate the hard board, soften the inner arm, and the whole wing can be retracted

so when making the wings of UAV, researchers adopt such a structure:

the red part in the middle layer is the straight and bendable "inner arm", while the blue and green parts outside are the rigid outer wall

due to the ability of "overcoming hardness with softness", the outer wall is separated along the middle line in the figure above. Under such a structure, if the UAV encounters obstacles in flight, the wing can bend along the position of the upper middle line, so as to avoid "aircraft destruction and death"

then, as long as the owner of the drone straightens it again, the drone will take off again, as if nothing had happened

here is the video of EPFL researchers showing this UAV:

Dario floreano, head of EPFL Intelligent Systems Laboratory, said: "At present, the development trend of robot technology is to create softer robots, that is, robots that can adapt to specific functions and operate safely with humans. But at the same time, some functions of UAVs also need a certain degree of rigidity. Fortunately, our scheme has proved that people can find a suitable balance between rigidity and softness."

combine hardness and softness, as if drones also need to practice Chinese Kungfu

the team playing all kinds of magical UAVs

epfl intelligent system laboratory can be said to be a group of UAV maniacs. In addition to origami UAVs, they have also invented many bizarre UAVs

for example, the red feather bird UAV:

the red feather on this UAV is made of glass fiber and nylon. It can fly fast, turn sharply, and even be afraid of strong winds

there are also unmanned aerial vehicles that imitate beetles, whose wings can be quickly extended or retracted like beetles, and can soar in a second:

and - unmanned aerial vehicles that can crawl on the ground with their wings after landing from the air:

-_-|| But... The speed is only 20 centimeters per second
