Robotics. About self-assembly of robots

After so much effort on muscle, I have gained considerable experience. I already knew in advance the pain points that would arise when trying to assemble a robot on its muscles. And, you will laugh, but I have foreseen something in advance. I have foreseen how the robot on the muscles will be assembled!

How to develop a robot without CAD (computer aided design) 

If you try to figure out how a real iron robot is designed, you will see how part by part in CAD the designer develops parts, calculates their sizes, stops standard screws, nuts, inch or metric.  This is an increasingly difficult job. An example of such work can be found in the opensource robot, which is posted on github, and which is being completed and redone by a lot of developers. The robot is similar to the Boston Dynamics robot, well, literally a little bit different. And much less. There is everything for him - control electronics, sensors, software. Or look at the one in the picture - also opensource. There are many of them now.

Even in this simplified form, this robot is terribly complex. And I came up with an approach how to make creepy simple. I'll tell you now, I'll just have some tea ..


About ease of assembly

Unlike a motor, or some other actuator, the muscle, in theory, should not be screwed or put anywhere. It should be fixed with its veins at two points, and just hang taut between two points. Look at the picture - you will see a lot of bolts, but I don't need bolts. If a muscle is warming up, then, in addition to nutrition and control, you also need to attach something to it that cools it. My muscle doesn’t get warm, so don’t. Well, if the robot runs like crazy with stones on its hump, then, of course, it will warm up slightly, and for this there is a very simple and elegant solution.

How to fix the core? 

Each of my veins contains an eyelet that is thrown onto a hook on the bone. Does not adhere, does not weld, does not stick. Just lashes out. It's fast. Baby can handle it. Or a silly robot, yeah.

That is, two bones with hooks are taken, connected by a joint, a muscle is thrown between the hooks, power is connected to the controller. Hop controller! - discovered a new muscle, pulled it up slightly, the operation was completed.

The bones can be of different lengths, they can be connected through joints of different power, all this is not important. The important thing is that even a child (or a robot) can assemble an android or a dog or a fish on a desk, without a CAD, and it can, in principle, move.

You can disassemble the android robot and assemble a new robot - a spider or a horse from the same parts. Well, maybe the hooves will have to be bought. You may have thought that I was planning to beat the popularity of LEGO? But they didn't guess. It will rather be a side effect. And I have conceived a much larger venture. And yes, I will tell you in next part.
