We want to make robots.

Humans are already made as robots by somebody else...

Our motors; Number of muscles

It’s estimated that there are over 650 named skeletal muscles in your body. Other muscle tissue, such as smooth muscle, typically occurs on a cellular level, meaning that you can actually have billions of smooth muscle cells.

The muscles of your body perform a variety of vital functions. Some examples can include facilitating movement, moving food through your digestive tract, and working to allow your heart to pump blood. Number of nervous terminals

the human body has 95 to 100 billion neurons or nerve cells. The brain alone has at least 85 billion of these cells, although estimates go as high as 1 trillion.

The 100 billion neurons or nerve cells not in your brain have terminals that can sense one thing alone each, some sense temperature variations, some sense stretching, somes sense pressure, some sense an exact range of chemiclas, like acid (High PH levels), base (low PH levels), salt, glucides (sweet), lipides (fats), proteines (fibers), or atoms and molecules like water, oxygen, etc.

Numbers of nervous procesors centres, rough estimate;

All those terminals, maybe around 8 to 10 bilion in total, found everywhere, in the heart, stomach, belly any cubic millimeter of a mucle or cartilage that might contain at least thousands of them, do not communicate with the brain, they send imput to local procesing centers, like some local Arduino Nano or Arduino One boards that only deal with a few thousands of them terminals at the time.

The information as processed in those nervous knots does not go to your brain, but it goes straight to another set of processing centers, regional processing centers, maybe one each thousand local processing centers, so those major neural knotts are by the hundreds of thousands in your body.
They are also interconnected among themselves at local and regional and inter regional levels, so that if a terminal dies, or a local processor dies, or a regional processor dies, it's job is automaticall spread on the others and you continue to exist despite the wound.
All toghether works as a brain, your "other" brain, brain in which you store information, issue thoughts, commands, react with, indipendently of the existance of your top of the head brain. But all this is not in a coordinated manner, so all has to go up for coordination expectancyes.

Your industrial automation server rack, the cerebellum.

Their processing results do not go to your brain either, but everything goes into you cerebellum, a small brain underneath your brain in the rear just above the spine, the place where every nervous terminal plugs in.

This is you operational management group of computers, more like a press compures center, or a banking system computers center, or a class A internet knot of servers, or a bitcoin/crypto currency mining rack of servers, something that receives imput from the network, decides the to do and sends the decision back into the network, this keeps you alive, this coordinates your automation, your heart beat, your temperature, your hunger, thirst, satiety, reproduction, this makes you run by pumping adrenaline into your system in case of danger, this is the one you train to swim untill it becomes just another automation, or to read, write, or any other skill that can be automated, talking included.
Most people talk without using their main brain, just fart straight out of their lower nervous system.

The brain you have, the gray matter that does not matter.

Nothing that happens in the cerebellum and beneath is communicated to the brain execept the exceptions, that is why you can day walk or walk in your sleep, you'll never acknowledge it, for walking is automated, the brain tells the direction and the goal to the cerebellum once, sets the peace and for the rest, the cerebellum takes over the eyes, muscles, ears, and you wake up elsewhere without any memory of how you got there alive, not run over by cars at traffic lights or when jaywalking. By the way, you do the same when driving, not a good idea but you actually do it.

And we want to copy that with stepper motors, pistons and a few hundred sensors... gimme a brake. Enhancing the image even more, under the electronic microscope where we can see every cell as a singel living person, Humans are a planet in motion.

Human beings are complex multicellular organisms made up of trillions of cells. Scientists estimate that the adult human body contains around 37 trillion human cells and 200 different cell types. The human microbiota (a collection of microorganisms found primarily in the gut) consists of a further 10-100 trillion microbial cells.

So we are talking here of two groupsof cells, those that make the human body, and those that invade the human body, mostly to parasite it, but also to give something in exchange, like the hosts in a hotel, they pay to stay.

The cells are living in cellualr comunities (muscles, organs, etc) that we can consider countries, about 200 of the on Earh... in the human body, each country has cityes, towns and villages, communication highways, transport highways, streets,roads and paths, rubbish collection and disposal services, grocery shops, cultures of food crops, energy production plants manned by specalised cells each. Each individual cell is a specialiesd cell, doctors, cleaners, transporters, energy producers, chemical plant operators, commnicators,transmitters, supervisors, etc,.

A cell dies naturaly in two manners, reproduction and implosion (Suicide) or it mutates in an enemy cell. The death by reproduction is by giving birth to two other cells, the children cells containg each half of the formerly adult cell body, DNA replicatd, everything.

But if the cell is dangerously ill, than the body will send it a suicide trigger signal and the cell will implode onto itself becoming garbage to be disposed of.
Or it becomes cancer.

Number of host symbiotic parasites collaborating in the system; makes the human microbiota (a collection of microorganisms found primarily in the gut) consists of a further 10-100 trillion microbial cells.
They are not human cells, but without them we would die of starvation, they are guest workers, illegal immigrants that found a place in the system and help it grow in exchange of food and shelter.

We are each Earth in miniature, or the Universe in miniature.
Your choice.

And you want to build robots?
Precise and accurate like humans?
I want to see you doing this.
