Where are the Robots?

By Robots I mean metal and plastic devices that look identical to humans , can do all things a human can do , are indistinguishable from humans , unless you get very close....

Where is the hold up ... the bottle neck???

From an engineering point of view humans are very simple , low power mechanisms ..an Olympic cyclist is only outputting 300W of usable power !!! A small motor weighing 200gms can do that ..

Since the arrival of neodymium magnets , motors, thinner than a pencil have been possible , with enough power to operate finger s , which is the trickiest part of the body to engineer ... The rest is easy ...Perhaps a few hundred motors plus linkages .

Power supply....5 kg of Li batteries would be more than enough.

Modern computers do have the processing power to make movements fine and delicate ... and visual recognition software to operate on the real world , make my bed , wash the dishes etc.

So where are they ???? ......The technology is being suppressed!

Given a billion Dollars and a few years , I could have them on them on sale at 1,000 Dollars each!

The correct term is android.

See: https://en.wikipedia.org/wiki/Android_(robot)

Far from it. Getting a robot to walk or run is an incredibly complex task. The software for it doesn't exist. The software to drive it doesn't exist yet and is far from coming into existence. There have been approximations for decades though. Look up the term WABOT-1

I believe robot is acceptable , although perhaps android is better ,from search ...
ro·bot
ˈrōˌbät,ˈrōbət/Submit
noun
a machine capable of carrying out a complex series of actions automatically, especially one programmable by a computer.
synonyms: automaton, android, golem; More
(especially in science fiction) a machine resembling a human being and able to replicate certain human movements and functions automatically.

I don't believe that for one minute ...just look at this contraption ...

WABOT-1


This is the type of thing a university produces with a handful of people and a tiny budget , and it's presented to us as cutting edge ... lol .... There is no great computing power required to keep an android balanced on two legs and walking.
And this was from the 1970's!!! ... has nothing moved forward in 45 years????

I would not call getting a Robot to Walk and Run an AI activity,
I would call that an exercise in defining autonomic control laws.
Admittedly these control laws have to be very complex if they are able to cope with difficult terrain or sudden unbalancing shoves etc.
I would suggest that these control systems are almost beginning to approach the ability of the human autonomic reflexes.
Perhaps mimicking the brain-stem and perhaps some of the hind-brain.
But the main cortex is still (many) decades away.

However the question becomes:
"at what point do you accept the Robot is giving an acceptable simulation of a human?"
There are various shortcuts that can be used to give the impression that the robot is behaving appropriately, within very limited situations.
To get a Robot to simulate human behaviour in an unconstrained environment is much more difficult.

The robots remain hidden while plotting the overthrow of humanity.

I'm confused. Who suggested that it was?

Human beings are anything but simple.

Robotics is a whole discipline and it's not easy to engineer them.

Sure... but now you have to imagine having thousands of such muscles all operating together to achieve a goal (such as walking, running, stopping a fall). Even motion on its own is a very difficult problem, but you've also got speech, autonomy, pattern recognition... it's an immense problem.

Note also that the brain isn't understood fully either.

Power supply....5 kg of Li batteries would be more than enough.

Modern computers do have the processing power to make movements fine and delicate ... and visual recognition software to operate on the real world , make my bed , wash the dishes etc.

So where are they ???? ......The technology is being suppressed!

There are companies that are developing robots with some impressive results, but nothing like you'd find in Blade Runner

Also... do you have a spare few billion dollars to develop robots? I don't!

Keep in mind that while all androids are robots, not all robots are androids. That's why I made that clarification.
