My Advanced Realistic Humanoid Robots Project

So if my pulley downgearing design works - and it seems I'm very close to this - just working on ironing out final details and configuration tweaks at this point.  Let's say it works and works very well - sufficiently to achieve my goals.  Then I am just about DONE as far as all design goes.

Drive the pulleys with a motor instead of very carefully pulling the string by hand. Connect at least one real joint and do push/pull motions to show that you can handle reversal and slack. Put some load onto that joint. Put it through a few hundred motion cycles to show at least a minimum level of reliability. Then we are talking.

Until that time I won't even get into the further "trivial" steps you mention.

Even though in my opinion, just showing great progress with elite skill should be enough evidence even at my current stage of development

I noticed a positive progress on your last few replies. You didn’t add more words like "great" and "elite”.

I mean, what do you think of me if I say the following?
I, the great engineer, discovered in year 1979 how to build a DSB-SC demodulator which is simpler and more reliable/practical than the known ones that are based on Costas Loop or the Squaring method. Even in these days, the scientific world, as of IEEE, is still ignorant about it.

Well, I personally hate myself if I say it. I would say instead:
In year 1979, I had the chance to build a simple practical DSB-SC demodulator. But since, in general, there is no more interest in DSB-SC system, there was also any need to add the topology of my demodulator, which has no I-Q signals (as used in Costas Loop) or a hi-Q selective filter (as used in the Squaring method), to the two known ones, at any university.

I think you said that you'll only be convinced if I set up the robot to pick up cups and place them in another spot or something.  So for you, I am not progressed enough to show any evidence.  Even though in my opinion, just showing great progress with elite skill should be enough evidence even at my current stage of development but you require more somehow.  I don't see why.

I want to point out how far along I am since xrunner keeps promoting the notion I've only just begun.  So if my pulley downgearing design works - and it seems I'm very close to this - just working on ironing out final details and configuration tweaks at this point.  Let's say it works and works very well - sufficiently to achieve my goals.  Then I am just about DONE as far as all design goes. 

Oh I thought of a great idea for artyrobot to work on - sortof a starter project. This would be a good way to move forward, to learn more, and to show the world he really can make something robotic that actually does anything.

Reproduce the Adam's Family "Thing"!

All it is, is a hand. It moves and grabs things, and it can hear you and respond to commands. If you can get that working I'd be impressed. Should be child's play for the world-class level of your mechanical and AI skills. After all it's just a robotic hand.

[vk6zgo]

You are using flawed logic. The goal is to make parts that will enable the functionality of the assembly to work as intended. It is not "cheating" to use the best available tools to make the best parts you need.

Yes it is cheating.  We are discussing skills here right?  That I showed lack of skills.  So somebody throwing some CAD into a machine and magically out pops part bypasses the need for meticulous eye hand coordination and patience skills to hand craft the miniature item using basic tools and techniques paired with massive skills and a steady hand which skillset would also enable expert heart or brain surgery as crossover application of same skillset.  So no, you using precision automation machines is cheating when you say your skill is superior.  By that logic, I can tell my robot to just make it and then say of the final product guys:  look what skill I have!  When the robot did it for me.  That's ridiculous folly.    And that is EXACTLY what you all are bringing.  IT IS CHEATING and this is obvious and the fact you cannot see this PROVES you are arguing in bad faith.

Back in the old days, Indigenous people throughout the world made very efficient hunting weapons using quite crude tools & materials, showing high skill levels, but such work was wearying & took a long time.
Do you think they would not have used more sophisticated methods & tools if they were available?
They actually did, following contact with more technologically advanced societies.

Is a person who shapes a spear shaft using  an engineered knife & fits a piece of sharpened iron to it for its tip less skillful than the one who makes the whole spear from scratch?

[vk6zgo]

As far as machining some small pulleys and some mounting pins for you to compare

There we go everyone 

He immediately admits he will cheat.  He will use a lathe, cnc machine, probably $100k worth of equipment to show he can build the same pulleys I did peice of cake right?  Or better yet, he will pull out his $1 million metal laser scintering machine for micro scale fabrication.  News flash everyone:  I made these with scissors, recycled plastic from strawberry containers and super glue.  You get to make it using THOSE methods, not a literal fortune worth of special machinery.  If you can prove you can do that while far exceeding my skils, THEN and only then do you have ANY room to talk smack.

A lathe is a far cry from a CNC machine, people build small items to high degrees of accuracy using cheap model maker's lathes all the time.They do so, by learning the capabilities of their relatively simple tools.

Yes, more expensive than scissors, recycled plastic etc, but able to be replicated to the same level of accuracy multiple times.
You have skills to make such things out of what is basically discards, but  such skills don't lend themselves to repeated accuracy.

Reproduce the Adam's Family "Thing"!

A useful, dextrous, human strength level hand with full range of motion, full human level degrees of freedom, human speed, etc requires so many motors that it would fill a 1 gallon paint can.  So making "Thing" is a waste of time since you'd be limited to putting all the motors into that form factor which means they would be under-powered and too small and make a useless hand.  It would also throw a human-like bone structure out the window to make enough space for them.  Which will make the hand even more crappy.  In other words, that project would be a total waste of time.

As it stands, because you need SO MANY motors so much mass of them and volume of them, I have had to put them throughout the whole arm, shoulder, and upper torso, mid torso, and even lower torso just to fit all the motors for the hand.  It is CRAZY how much space they all take.  But I believe it will all be worth it to have the best hands in robotics history which is basically a guarantee at this point.

[artbyrobot]

A lathe is a far cry from a CNC machine

Not really.  Both are widely considered non-options for makers and DIYers.  Lathe people tend to be lathe fanatics and make everything with lathes and seem addicted to them.  Their whole YouTube channel becomes all about lathes.  So there are lathe DIYers and non-lathe DIYers.  The latter is 95% of all DIYers.  You alienate 95% of DIYers the moment you say "okay guys, the next step is pull out your lathe and do this or that".  Not going to happen.  That's when they stop following and will not repeat your steps.  It also rules out everyone who lives in an apartment and most college students etc.  Most people don't have the room in their house for a lathe either.  While there may be more budget friendly lathes, most people aren't aware of this and the assumption is they are trash so you have to buy a real lathe which is too expensive etc.

In any case, if anybody wants to talk smack, show me glue and plastic type superior pulleys.  Otherwise, you are assumed to be all talk.

Who said anything about putting all the motors into "that form factor"? It's a test of a sub-system that you currently have no data on because you have no idea if it will work properly. You are just testing a hand. Where did you conjure up the requirement that they all have to be fitted into a small form factor?

Get a work table and put all the motors and other hardware there and put the assembled hand at the end of the table. Geez have you no clue how to test sub-assemblies before actually moving on the the next step.

If you really want to see some of his "perfect" code ... i.e. some of the worst code you have probably ever seen...

Dive in at https://github.com/artbyrobot

There is zero functional code in any of the repositories at that link. All I see is a bunch of irrationally formatted and constructed nonsense.

artbyrobot, you claim to be a deeply religious person. Don't you worry that your god will punish you for your wilful sins of pride and arrogance?

[joeqsmith]

I'm just surprised you claim this is a business

Part of my plan for the robot will be it mowing lawns for neighbors for pay.  Not part of my plan is selling my robot for pay to a person who wants to own a robot.  Therefore, to assess the quality level of my robot is measured by different metrics.  The quality for a customer is not is the pulley looking professional on that motor? but is did the lines on my lawn left by the mower look straight enough?  So in that way I claim it's a business but it seems you suppose selling the robot is the business and the polish of its internal components have to match what you'd see in a car's engine bay.  That's false.  ESPECIALLY false for it being a prototype. .....

The IRS would know if you have three businesses as you claim.  Do you have a federal ID number?   From your posts, I very much doubt it but you are welcome to provide further details about them. 

[joeqsmith]

As far as the work speaking for itself, I agree that in the long term that will be the best defense against the bullying and toxicity.  However, what about in the interim?  [...]
So my work won't impress until it reaches certain landmarks or milestones like picking up cups and placing them in new spots or w/e. [...]

So in the meantime I think the best approach is just to trash talk right back to the haters and bullies.  I don't see any downside to this. [...]

Have you considered just shutting up and focusing on your work until you have something to show?
Anyway, nice summary of your attitude and this thread.

Something to show like more thumbtacks, glue and beadless splattered welds that never penetrated?   The only thing they appear good at so far is trolling.  For that, I give them an A+ with a gold star.    I'm here for the entertainment.  Not to learn about AI, robots and business practices.

@artbyrobot, I have updated the "About" section for you.

[SteveThackery]

That is some serious names for variables 

To be fair, the compiler doesn't care and will produce exactly the same code as calling your variables x, y, i, etc.  It would be better to take the piss out of something that actually matters.

Is there some actual, executable code we can take a look at, and not just pages of variable declarations or those pseudo-code moral imperatives we saw the other day?  That's likely to be much more revealing.

Hi-res image of world class, elite power supply.

I liked the crowbar (redrawn circuit attached):

If the voltage output is too high due to failure on the part of the buck converter, then the voltage divided line coming out of the voltage divider will reach up to 10V which will be enough to turn on the lowside n-channel mosfet which will short the system - when this happens, the fuse at the start of the system will blow and the system will go dead

And the battery charger buck:

This buck converter brings the 18V 100A DC down to 4.2V 428A DC to charge the 5 li-ion batteries - each battery will have a mosfet in its charging circuit that will be used like a resistor to bring the amps down to a safe level for charging that battery; the 5 li-ion batteries each have the need for their amperage to be throttled down to 1.9 amps tips which is a 0.9C rating for their 2000 mah capacity

@artbyrobot, do you agree, that this power supply is trash and nonesense?

Looks like you left out the fuse on the front side of the crowbar.  Does the robot need a million mile extension cord?

Ah, yes, forgot the fuse.. Maybe because fuse is usually found before the bridge rectifier. For good reasons by BTW. First, it makes sense to have fuse at the AC input before any other components. Second, it allows the use of cheap fuses, which are not rated for high DC voltage. It is harder to interrupt DC and fuses get more expensive. Anyway, original is attached.

Total garbage is what it is! I love the uC that will directly drive the FETs in the 'buck converter' (not that the entire pile of excrement would have the smallest chance in hell of working). Nice that the circuitry is non-isolated as well. The entire 'design' demonstrates the complete lack of any technical knowledge or even appreciation of that lack. I hope the OP never attempts to build any of it - it's a death trap.

I'm still hoping for the OP to admit it's all been a great hoax for our amusement. The alternative is very very sad.

cheers,
george.

I tried to rectify the AC line to power Dave's meter without a fuse.....   Note my perfect soldering compared with OPs.

Hopefully the plan remains in the theoretical domain and stays on paper.

That said, if the plan is implemented in reality, it reminds me a bit of this:

beadless splattered welds that never penetrated?

my welds penetrate well.  Your suggestion they did not penetrate is folly.  You did not test the weld's penetration, do not know how long or how I did the welds.  You weren't there and I didn't film it.  You have zero way of knowing what you claim.  So it is pure speculation and utterly false.  Just like most of the statements in this thread from haters.

[artbyrobot]

You say you liked the crowbar.  Are you suggesting sarcastically that this won't work?  If so, what is wrong with it?

I designed this elite power supply.  You are saying it is trash and nonsense?  Why so?  I think it's great.  What is wrong with it?
