WIP - Crawler

riker3667 · 25-02-2004, 02:13 PM

K.. this is a continuation of my WIP - Battlemech thread. I am starting another thread for it as the mesh/design/etc got rather drastically changed...

Here are the 6 legs for the crawler:

I've yet to decide whether to place footpads, or to leave the legs as is...

I've also been considering placing a "shell" over the legs, to protect/hide some of the components....

Opinions, etc

Note: The legs will b quite a bit more spread apart in the center area. There are shown as is only to denote progress so far..

looking good so far, could we maybe see a wire or blueprints or refrences that u used...

riker3667 · 25-02-2004, 03:32 PM

No Blueprints etc..

straight outa my head...

here's the wiremesh:

Dedalo · 25-02-2004, 03:38 PM

Looking good , it's would be great if you make some animation whit this.

riker3667 · 25-02-2004, 09:47 PM

Thanks. I am planning to animate this mesh, when I get the sucker done...

I'm planning to run a camera track from the inside, out & around/over so I am trying to get alot packed inside

Here's what I've done on the body since my last post:

For those that are curious, here's the wireframe of that pic:

BTW: I wil likely need ALOT of help animating this. Files & LOTS of appreciation for upcoming assistance

As always, comments/critiques, etc welcome.. This is my first really large project for myself so I am striving to get it REALLY great looking when it's complete.

nice idea... i like the concept!

i know its real early stage...
just wanted to know how will the crawler move forwards?

do the legs have that kinda freedom to move
forward and backwards?

Yes, it can/will move.

Once I've finished the mesh itself I'll start in on TRYING to get it all animated.

At the moment, each hip has a 60 degree arc of movement on the Z axis:

Plus each joint below the hip has a generous rotation radius:

I've yet to add in the foot pads to the legs. They'll probably have a 40-50 Degree arc as well.. (once I figure out they're design..lol)

Hmm, maybe I am missing something, but isnt this over engineered?

Wouldnt 1 joint enable it to walk in exactly the same way with the other 2 joints fixed?

1 joint to lift the leg, 1 joint to move it forward/backwards?

Yes, I could have simplified it as you suggest, except for two points that I considered making the "over engineering" a plus:

1) with the extra joints, I can extend the object's footprint

2) It looks better this way (in my opinion

)

g69 · 26-02-2004, 03:35 PM

i saw the avi clip you did...
its good, but i think there is something un real
about the 2 supports of 60 degrees axis...

well, if they are there to push and pull... they should
contract and relax (increase & decrease in lenght)
but i dont think so it does in the animation.

or maybe i couldnt notice it...

anways, ur doing a great job...keep workin on it.
and keep us posted

riker3667 · 26-02-2004, 05:13 PM

I'm assuming you are referring to the "hydraulic pistons" on the joints for the legs.

These do move, but only in rather a small way (hard to see in the full image.

I made a quick avi with the joint area blown up to show this.

Click Here for example avi file.

A friend of mine rightly pointed out that for the Z axis (hip) joint I need to offset one or both of the hydraulic pistons to enable it to work "realistically". I will be doing that next and then continuing with the chassis & body meshes

g69 · 26-02-2004, 10:57 PM

yup i was refering to the pistons...
and yeah i think its not viewable...

this is what i meant though
check my Example

dont expect it to be perfect... this is just a 2min setup!

[you might need divx to view, if not already installed....get it here ]

riker3667 · 29-02-2004, 08:01 AM

k.. I've made several edits to the legs & started in on the lower chassis...:

Opinions, etc?

ManiHack · 29-02-2004, 08:22 AM

I find this Mechanism unrealistic, there's nothing "real" to it, just a couple of polygons sticked together. + you have som nay polygons for nothing.

riker3667 · 02-03-2004, 08:38 AM

Unfortunately. I have to agree with you there. lol

I'm placing the project on hold as I go into major re-design of the legs & lower chassis.

With luck, I'll be able to post fresh progress pics in a few days.
