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

In amongst the fervor of Christmas-related activities, I managed to do development work this month. Not as much as I would have liked, but one major goal's been reached: the newest version of the Text Parser is parsing all the sentences from the previous one's regression tests, plus a number of new ones that would have been impossible for the previous Parser. I still need to do assorted code cleanup and adjust my reference outputs for some format changes, so I can run the benchmarks again.

With all the types of adjective and noun clauses now supported, the last major grammar feature that needs to go in will be parenthetical noun phrases. This should move the majority of common sentences into the "theoretically parseable" category. Then I can start refining the process and working on cool features I've been wanting to explore for a long time - like word sense disambiguation, modifier attachment disambiguation, and pronoun dereferencing ... there's always so much to do. It's taken much longer than I expected to reach this point, but at the same time there's a great deal that I've accomplished.

I'm soon due to start planning my loose schedule for the next year, which has me excited. I'm looking forward to the completion and demo of Big Story, a fresh run on the Parser benchmarks, and probably more work on Game Playing and agency.

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 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.

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.

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

Openscad gold render.

(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.

https://www.youtube.com/watch?v=kysKINVJjr4


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!!

that would give the robot a good advantage,  because occlusion disturbs robots more than people cause of being based apon strict methods, that could bring back the whole place fully 3d tracked, and things being in the way wouldn't affect it as much.

I actually might make one myself now,   this idea seems cool for computer vision, I think ill try doing it like an old mouse (sorta backwards tho) with little rollers.   See what happens.

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.

https://www.youtube.com/watch?v=Op3ahzAdPBU
https://www.youtube.com/watch?v=J23-1z8mcPY

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.

Something fun I've thought about is to have eyes on little drone platforms, wirelessly connected to the main robot body. But that's a theoretical project for the far future, probably. First, I have to finish this eye!
