Robotics. Muscle idea

When it comes to robots and robotics, we are presented with a stereotyped picture - a mechanism assembled by human hands that performs routine monotonous tasks. In reality, everything looks different, robots are capable of performing a much larger volume of tasks, self-learning, and even have muscles...

Let me tell you something about muscle work.  You are unlikely to hear such an insider from anyone else.
The author of the article is Sasha Sergeev - a specialist in the field of robotics.

Background

Four years ago, no, even before, I came up with cool robot muscles. Strong, lightweight, fairly fast, much cheaper than competing devices. And that is why they have an advantage over the use of motors in the legs and arms of the robot.

It was immediately obvious then that controlling the muscular system was a more complicated matter than controlling the motors. The solution was found and was tested. It would seem that everything is fine, you can move forward. I dreamed of billions of elegant robots dancing around the clock. Several angel investors offered me financing at once. The conditions were not very good, I did not take money. I somehow very quickly set up production without them, and only with one important node there was a certain incident.

Meanwhile, in Japan, in one of the robotic institutes, they invented something that practically repeats what I did. Without the tastiest things I had, but the principle is the same. My muscles were light, the Japanese were heavy. My are stronger and cheaper.  I had a plug with an important knot, and the Japanese did not bother with it. I had a natural load balancer and the Japanese didn't give a damn about it. But it doesn't matter.

It is important that the idea was in the air, and numbered in several places. The Japanese had a research laboratory at the institute, a whole team, huge funding. Therefore, they thoroughly measured everything, I then compared it with theory, everything agreed, everything is fine. I could not measure it so thoroughly, I have a garage, not an institute, so the help of the Japanese was very useful. I still have priority!


Angels or pocket funding 

Then I had a choice. Take angel money or take a nursing project for an old specialty. I chose the latter. Was it right or wrong it's hard to say. Feeding project meant high workload, less energy to think, defocusing. As it turned out later, this nursing project wasted my time and energy to the fullest. It also turned out to be a candy, and I'm happy with it, but now I think that it was necessary to get out of it early.

First application

I tried to work out at least a muscle-on-muscle limb. It wasn't that easy. If you figure out how you need to make a REAL living hand, torn from a person, function, then you will understand me. For the fingers to move correctly, it is not enough to supply nerve impulses. They must be taken from somewhere. But there is no brain! And there is no heart, but where to get blood? And there are no lungs, and the blood must be with oxygen. And there are no kidneys, but the blood needs to be cleansed. There is no bladder and rectum, but this is so, by the way. There weren't so many problems in the artificial muscles I made, but the situation was somewhat similar. That a limb, that a complete robot was equally difficult to do. It was work for the team, and I was the only one left on my team.

My muscle could only be of a decent size. He couldn't be muscle for a dragonfly or a little mouse.  Its manufacturing technology did not allow it to be done. And therefore, making a toy on such a muscle was not realistic. Several times I looked into a new area of ​​knowledge called MEMS actuators, but it required equipment, and it was terribly difficult to develop everything there. My interest in toys has dried up.

And then I, already somewhat tortured by the nursing project, tried to come up with an application - "not a robot", much simpler, but in which the muscles would play to the fullest. And I came up with such a project, and at the same time I made a couple more inventions.


Flying saucer

I came up with a flying saucer, or rather, a flying machine with a new propulsion system. Its control was quite simple, only two light and strong muscles were required. No brain needed. Offhand, the prototype came out cheap, and it could have been made in a couple of months in free time from the feeding project.  So it came out. It just needed to make a lot of broken models before the displacer still soared. And some more working models. The material of the propulsion ripped up before the design capacity. In the end, I practically surrendered. Just quite recently I realized how to make a cure for destruction. And at the same time I realized another thing...

To be continued. Thank you Sasha Sergeev for his work and development. Original text available link.
