How have you hinged the diagonal toes? (sorry if you've already said, my heads running on fumes today)

Looking fantastic though black, I must admit I'm increasingly jealous

See no roll over to the next page.

No I haven't installed the hinges as yet I just got this inspiration about an hour ago when I was setting up to take the pictures. I wanted to show how the corner toes intersected with the hinged front toe because Xypus requested it and I just got this idea that the toes could rotate on a single axis. We'll have to see.

Coincidentally I made some hinges for the disc tilt mechanics until I changed to the spring tilt mechanism........... they should do admirably to animate the diagonal toes I just have to recover the rest of them from my scrap box

And there's eight of them.

So the diagnol toes will tilt each opposing toe on the same axis? That lends for some terrain navigability.



Is that a word? Navigability...... LOL, I is stupid.....

In a word Max, no lols

NAVIGABLE. Capable of being navigated.
2. In law, the term navigable is applied to the sea, to arms of the sea, and to rivers in which the tide flows and reflows. 5 Taunt. R. 705; S. C. Eng. Com. Law Rep. 240; 5 Pick. R. 199; Ang. Tide Wat. 62; 1 Bouv. Inst. n. 428.
3. In North Carolina; 1 M'Cord, R. 580; 2 Dev. R. 30; 3 Dev. R. 59; and in Pennsylvania; 2 Binn. R. 75; 14 S. & R. 71; the navigability of a river does not depend upon the ebb and flow of the tide, but a stream navigable by sea vessels is a navigable river.
4. By the common law, such rivers as are navigable in the popular sense of the word, whether the tide ebb and flow in them or not, are public highways. Ang. Tide Wat. 62; Ang. Wat. Courses, 205 1 Pick. 180; 5 Pick. 199; 1 Halst. 1; 4 Call, 441: 3 Blackf. 136. Vide Arm of the sea; Reliction; River.

Cool, it is a word. I thunk i had made it up......

BTW are those 360 Snake hinges?

No they are 180° Flamsten swivel bases.

Now that that's cleared up I've come to a dilemma namely do I follow the prototype or redesign the leg mechanics to appear workable.

The hydraulics on the inner and outer shanks certainly look impressive but they serve no purpose as control devices. the extremely long cylinder on the outer shank terminating in a Leman Russ drive wheel does nothing unless it is intended as an oleo strut shock absorber but then why is it so long with an identical cylinder at the knee joint and why isn't there another of equal diameter opposite on the inner shank?

Could the knee joint also need a shock strut? I see no indication of flexibility in that area.

The smaller strut off the back of the main terminating in the LR bogie could be a stabilizer to tie the shank to the quadrant.

In itself the shock strut makes sense but aside from artistic license shouldn't there be a similar unit on the inner side?

The upper thigh will have to be sorted out when I get to it.

I think it was done because it looked good unless it is intended to represent a drive housing of some sort and not a shock. I'd say redesign it. Your knowledge of engineering would provide a unique insight.

I don't see why the knee would need such a shock. But, then again, maybe. It is a massive machine.

But I am a little lost on what you mean by the quadrant.

I think you need to realize that artistic license played more role in the DS BoLS than you may have figured. But I have faith in your engineering. It will look good as a copy of the original or as an original of your own design.


Incidentally, are there any drawings of the inner workings of the legs of Asimo floating around? Not that they would be indicative of what this should look like but structurally or mechanically do you think they may give any ideas as to which direction you should go?

I strongly suspect that Asimo (A tribute to Isaac Asimov mayhaps) uses electric servo motors instead of hydraulics.

There's quadrant, sextant, and octant, mebbe even decatant but thar ain't no word in the English language for a semicircular device (Other than semicircle) so the half disc gear above the ankle disc plate I designated as the quadrant.

semidant, demidant, hemidant, perhaps?

Finally; I am not an engineer but I play one on the internet.

You don't always play an engineer on the internet. But when you do you do so well. Keep building, my friend.......

I wish I was immodest enough to say that. It fits so well with the avatar.

She's got legs, Er lower legs, Er well plastic rectangles and she knows how to move them, Er well you gotta move them for her. Hmm sounds like a recent date.

Anyhow the pivots seem adequate and should easily support ten lbs each.

Put dispenser here!

Also, are you going to power the legs so it can walk on it's own?

POOTIS!

Keep up the good work, Blackadder, this is a project of titanic magnitude!

If he does that, I will sell my kidney to buy the damned thing!!!

on a serious note, I doubt he will, as the weight will all be in the torso. but also, he'd have to make or factor in gyro stabilisers... and some how I don't think Black has the funding Honda does

Is it possible that there could be some sort of anti grav plating in the foot? the imperium has antigrav tech and the starships of the imperium utilise gravity plating so that people don't float around.... Land speeders float around... the anti grav plates could support some of the weight of the titan meaning that the foot in motion can still bare some of the weight?

Mullet, yes the imperium does have anti grav. But bibblles was talking about making it walk in real world terms i.e. making it fully functional. which just isn't possible tbh.

At first I thought hemisphere but that would be half a full sphere - hemicycle could be what you're looking for.

Tbh monkeyh, I think for the terms he's using Hemidant is the best description for it.

tbh there may even be a name for it, but I'll be damned if I can find it lols

See we've gone where no man has gone before. Who says gaming is a waste of time?

And no antigrav; who needs a titan if there is antigrav?

Precisely!

Not really having a good grasp of geometry, I would have said it was a semi-circular disc.

But as far as a proper shape name, I don't know.

No, No, NO!

It's gotta have a name. That like saying the "United States" has no name it just says what it is.............. Hey wait!??????????????

LOL.




Good one, Black.......

Okay buoys and gulls the Blackadder is trying out his new point and shoot. Whut happened to the T3i you may ask? Too friggin' complicated says I. So I got me a GE X500 for quik pixs. hey it's only money..............

So the inner workings are the subject of the next few posts. These legs must support a relatively massive superstructure so an internal framework is required. I'm starting with a 22 mm lateral support to build on. I probably will add structure below, especially slides for the shank to run on but first I have to establish a mean width. 22.0 millimeters seems about right.

This is where precision rears it's ugly head; if you want your legs to be straight and true they have to resemble each other to the nearest 0.001 inch. That's only a couple of passes with your sanding block.

So get out your digital vernier calipers, it's go time.

22.0 seems about right. How are you going to build the super structure up, boxed or other?

sorry If I'm jumping ahead lols.

Yea, that's probably why I had to rebuild the legs on mine 3 times before It wouldn't rock back and fourth...

But this... this is a whole different level of titan...

You can jump ahead as far as you like but I'm of the Ted Kennedy philosophy:

We'll cross that bridge when we come to it.

haha

I am of the philosophy "question everything, deny nothing"

I just wanna see it done. But I love the process you go through, Black.......
