Its taken me a long time,  somethings been holding me back from doing it.  I'm so sick.

My robot is starting to solidify as an idea,     I want to do it without electricity  and its basicly an eye connected to the computer connected to its actuators.

Hopefully Something has a from scratch computer design here,   and I'm doing one too.     I've been studying in Falstad electronic simulator for ages now, and I'm trying for an amplifier with only resistors.    I have got it done with transformers, I figure as soon as u have an isolation, be it an isolation transformer, or staging through capacitors over time, an amplification is possible.   Doing it without the isolation is barred by the fact some topologies you need for amplification aren't possible due to being extraneous circuits that get logically simplified off and don't exist (Unless u have an isolation.).     But I have a new idea for one, so I haven't given up -  I've been doing the past decade, without results.  I feel like I'm in prison doing something that'll never get me anywhere and I'll be dead before I finish.

So once I get the amp, I convert it to be an oscillator.  (Here is the oscillator I want to reduce the transistors from and make it fully solid-state pneumatic->)


I don't want the robot to be too strong,  without the right safety measures in the Ai it would be really stupid to make the actuators too tough,   I've learnt how to electroform metal and I know how to make thermite and know how to set good hard minerals,  so I can build the robot full metal, so I think I need to make it skinny enough to not be too brutally put together too well, making it dangerous for everyone and me as well.

Also, it will be flying and have hands so it can pick things up,   Why go on the ground when u can make a bird, I might be able to get the robot to give me short lifts to the shop and back hovering me just above the ground not to be dangerous about it.       So just need to get the amp going, then the computer,  then I'm pretty much ready to go to the foundary to get this big moving metal statue done!!

I dont know how much longer, I hope its soon.     I've been doing this for decades now, I need it, I'm getting tired longing for it.

robot body is coming out tomorrow sometime. (This is the finished one!!!!)






more formulations,   going to work all tomorrow on it, hopefully finally get it done, been a long time not being done, thats for sure.
its going to have more than 100 dimensions!!   lots of actuators.


<edit - just chipping in the hydraulic tunnels>


keep going...

[MagnusWootton]

Its going good,  I took a bit longer than I wanted but it should still get there.  the rotational bellows are just starting to go in now, and some of the hydraulic lines are in.

Its got a really cool short assembly,  theres just a top half and a bottom half and then it just whams together with a bit of glue on the seam.   (the whole robot should be two halves, whams together all in one.)

Should have it finished today,  I'm getting bugged by the mental hospital so if I can get this done then it'll put me in better sted with them for a little while longer.



<edit> next vid to show will have a much better bellows, ive fixed the method. </edit>

[MagnusWootton]

Showed off the parameterization, I went from 4 hydraulic lines to 8 lines, but its a bit slow, open s-cad can slow down on you if u write code it doesn't like, I've got my workaround for it so it should be alright.




see If I can get this thing done today.

  * bellow needs to be fatter, need to fix the discontinuities.
  * Im going to make it a more aggressive/acute angle, so it makes it easier for a stiffer material to make the angular distance.,
  * its going to be simulated with expansion and contraction with an animating lever, using the open s-cad animation ability.
  * the bellow gets a correugated seam all the way down the side to seal the top to
     the bottom.
  * one of the bellows is the power bellow, so its going to get more girth to step down the power,  so it fills slower but is stronger with the more square inches.

  * its getting a flexable connector on the end, so i can twist and bend the robot into the correct axi,   so I can actually cast the whole thing flat and I bend it to get pitch,yaw and roll post casting and it can still be a single continuous piece.

     - so Ill be back half a day or so with it finished hopefully.  I'm having a break down.

[MagnusWootton]

(dont mind the stupid music in the background, just turn it off.)

So here it is animating,  and the bellows is not behaving realisticly, so im going to put a bit more fixes on it, and see if I can get it more realistic, at the moment its looking like its puffing up like it has air in it,  but its actually hydraulic and that doesnt happen.




so jobs to do->

  * fix the animation
  * add the bellows seam
  * the powering bellow needs to be girthier than the conduct through bellows.

 - then ill be pretty much ready to put out the first robo with it!!

[MagnusWootton]

Few more connections to make,  but it ended up looking half ok.

Openscad gold render.

[MagnusWootton]

That actually Isn't my dream robot yet,  that is just his hand,  and they are quad spiders.

The real thing looks like this as a dodgy sketch of it from that picture->



So hes got wings, a spine,  hes got wrists, hands, and a neck and head.   it comes to over 100 actuators, and its already going really slow.
So I have to have some work around even to render it.  Ive even planned an ear and mouth as well.



<edit>

Ive done a bit of work, looks like I managed to do a work around to get it to render, still got the wings, the spine, and got to play with the thickness cause its a bit flat at the moment.



Variating thickness going up to the main body.



Now going to add spine and wings.

[MagnusWootton]

I got the conductor count wrong,  so I had to redo the whole thing,  I think it looks slightly better. (Even tho im probably biased)  Cause the machine is more correct now.

[MagnusWootton]

Ok I've enough for a while,  I'll get back to it tonight.   just look how slow it is!!! (it makes it a real pain.)

The central spine has to have a hydraulic connection for every bone after that joint so it ended up with 200 conductors on it,  all the way to the finger, it has to conduct the fluid through till the end...   so it ends up taking up tonnes of space, I had to throw the roll and the yaw and just keep the pitch for the central spine, because it was turning into a caterpillar just about.

There's little nubs on it where the wings are going to go,  I'll do them tonight, and I'm missing some important connectors as well and they are going on.

But the biggest mystery or bummer, is I know how the power source is going in,  but the computer and eye I'm not sure of yet so its just an empty casket without the real goods in it yet. (im not sure if its going to fit.)

But it turned out better than I was expecting, I was lucky enough to get what I got,  So still waiting on the wings for the final "effect" of it, (for now anyway.)

I could probably post this thing anywhere and get a small amount of attention for it, as a functional model, its pretty cool design.   

I'll be back later on tonight with a nice set of folded up wings, like a cockroach or beetle.


<edit>
Screw it, I've had it for the night,   but I just got an amazing idea.  If this system is only a top and a bottom,  its harder work, but if I boosted it to 10 layers I can send more signals on top of each other, and then the whole machine is reducted in size.     Its the bellows that stop it from getting smaller, so if I vol increase it by 10 layers, then much smaller footprint, but I've got 20 moulds to make instead of 2.     

So thats really cool and I dont mind complicating the system a pheasable amount for it, and I do get one more thing from it,   the pneumatic computer can also have 10 layers, and that may come in handy.

The power system I easily get done in 2 layers, so thatll stay the same, I'm not sure how big it needs to be, but smaller volume is safer when it comes to high pressure.

I like how you combine one axis rotators to achieve rotating over all three axes. Very imaginative and clever solution.
