The stabbed opponent is a famous bee that gives one of the most painful creatures on the ground. Because the pain was so severe, the victim was given a scientific follower of "falling down, screaming and waiting for the pain to disappear."
But little is known about the bee's ability to carry unimaginably heavy cargo from that small body.
The secret weapon of bees, the interclaw disk.
An ordinary small drone, also known as a subminiature unmanned aerial vehicle (MAV), can only lift objects of the same degree as its own weight. That said, if drones were as big as giant pterosaurs, it would be troublesome. In that case, you must consider a new way to pick up your luggage.
So the designers of drones turned to bees for help.
Bees use needles to pierce prey to faint, but if the other person is too big to lift, they drag the prey away instead of flying in the air. What can do this is the "claw disk (Sooukaban)". This is the part on the toe of a bee that can firmly capture the surface of an object.
By combining the claw disc with the claws, the bees can carry things that are too heavy to lift.
Stick it on the table and roll up the heavy objects
Engineers are considering making drones do the same thing as bees.
"FlyCroTugs" is a new robot inspired by people raging in the air. At first glance, it looks like four common chapters the size of the palm. But the part of the abdomen hides some kind of secret.
There are two versions of Frakrotagus. One is the type with a hook, which is hooked to a protuberance or dent on the ground surface to firmly secure its own fuselage. It's like a bee putting up its nails. The other is the type with pads that fix the fuselage on a smooth surface.
In addition, each machine has a very small winch (winch). Use this to lift and drag heavy luggage that weighs up to 40 times its own weight. The structure of the hook is really very simple, which is a forward attack method that uses the lever principle to fix the body on the ground.
"I'm trying to put multiple hooks next to each other. Each hook grabs the protuberance on the ground and pulls it up together, producing a much greater force than a single hook, "said Matthew Estrada, a robot researcher at Stanford University." He described the machine in detail in Science Science on October 24, 2018.
The structure of the cushion is inspired by the gecko's legs, not the bees. However, this is not a particularly new technology. Researchers at Stanford University have used this technology to design devices to capture and recycle space junk. Having said that, this technology does give eagles and geckos the same grip and the ability to lift things like insects.
A task that cannot be completed is solved by quantity.
What makes this kind of art possible is a function called "van der Waals power". The bottom of the drone is densely covered with tiny protrusions made of silicon. When you land firmly in a smooth place, the protuberances fall in the same direction along the grounding face (see GIF animation below).
