Theos quad tank thumbs 001 by VulnePro Theos quad tank thumbs 001 by VulnePro
Here's a pile of walker tanks, with a couple of bi-ped gerwalk light tanks as well. Most of these tanks are, clearly, based on German assault guns so many evoke the earlier Blid Wolfspinne quad tank I designed which was also an assault gun based on German armor:

Obviously we have a "Hetzer" type in there, a few pseudo Jagdpanther/panzer kinda deals, etc. The legs on these things all have, more or less, similar covered style designs as the more recent 5th generation FOILs. Again inspired by the creepy feel the US Army's combat robot Big Dog has. Many of these tanks have reactive armor plates and they're pretty obvious on the designs to those of you familiar with what reactive armor is. It's been awhile since I did any walker tanks and frankly they're a ton of fun to come up with. I really should have done some sooner :)

These are all really small thumbs overall, an inch in size or smaller. As with the last two batches of FOIL thumbs I added some quick and dirty colors to pop em out a bit. I have a feeling I'll end up doing a few more finished paints of some of these.

Once again this is posted as a main gallery deviation to alert watchers that these roughs and thumbs are actually all in my scraps gallery. All this kinda of stuff ends up there. More work is coming soon. I hope everyone had a Happy Turkey day. Cheers!

I like your concept of walking tanks.

My thanks :) This is just a collection of rough thumbs but often the more refined ideas come from stuff like this. There will be more in the future and, if you missed them here are a few more:

I like the way you took the original tanks and changed them like this, very cool!

Aye, indeed most of them were derived from something familiar and mutated into what we have here. There are reasons for the familiarity in the story but getting into detail would spoil it, so I won't, suffice to say there's reason for it also narratively.

Thanks for the kind words :)

My thanks for noting this and indeed I'm aware of the correct usage for 'and' (in Greek) being Kai, however I'll drop some of my reply to this before here:

You're correct, naturally being from Greece, about Theos Kai Polemos being the accurate spelling.

The title's meaning, in context of the story, is actually Theos KE (KE being the common abbreviation for Kinetic Energy) Polemos implying a more violent collision of spirituality and war Theos >KE< Polemos = dissonance. In contrast Theos Kai Polemos (God and War) is more passive, less discordant (though accurate as noted). Most will still read it as God and War and this is fine too as to context for the story. The story is about a fractured dissonant future with a broken sense of the past (hence having both Greek and English mixed in the title). The title does sum up the stories themes both literally and allegorically.

Quad Walker, Polemnos Ranger!

After seeing some of the videos here, the spiderbot in Supreme commander does not seem so far fetched.

Looks great.

Thank a ton Adam :) I had been itching to do some walker tanks for some time and due to looking at a lot of Ma.K of late (for rather cool reasons I'll probably reveal at some time in the future) it inspired me to get to doing some. More cool stuff is on the way :)

Oh man, these are so awesome...There's something "Big Dog"-like in the articulation of the legs; I can really see them galloping along, moving with a bounding rather than a stereotypically spider-like/crawling gait.

Remind me also of some of my all-time favorites on the theme of walking tanks, the Junk Tank Rock tanks!

Thanks a ton, I appreciate it :D Aye, there indeed is a Big Dog vibe to them and I noted it in the description :) Something about Big Dogs legs is both cool and supremely disturbing so it influenced my, already in the works, decision to explore covered legs on FOILs and, now tanks :D

Yeah indeed familiar with Junk Tank Rock and yes... they rock XD No direct influence though. In fact I had forgot about this site until you noted it, thanks man :)

D'OH, that's what I get for skimming the description! :ohnoes:
A mistake I won't repeat.

Also meant to mention the work of kinetic sculptor Theo Jansen, if you're not already familiar with it:

One of the more imaginative takes I've seen on walking "machines"! :)

Oh don't sweat missing that in the post at all :) It's cool you guys brought it up, missing the comments I made about it or not. I found Big Dog to be a rather striking, almost psycologially impacting machine, it's just damn creepy. Pretty cool too but really unsettling watching it walk so, more and more, you're seeing it pop up in mecha design as a point of visual reference. It's a damn good one too.

Aye, I'm familiar with this artists work and it's really cool as well. I just might explore some ideas like this too but often military applications seem to keep things straightforward and I expect a potential walking tank to probably follow that line of thinking. Of course it's speculation and I could be very wrong too :)

Thanks for the links and bringing up Theo Jansen's works.

Danke! Actually I noted that Big Dog inspired some of these in the posting ;) Also I do have some more animalistic smaller ones I haven't posted but for tanks, overall, I want them to look like a tank.

These are awesome, and a great example of the "theme and variation" method of idea development which I have found to be a very productive way of working. ReneAugustus' point is well taken, and if I can expand upon it I think that the idea is to approach the problem from an engineering perspective, rather than a strictly visual one. How might the legs move, in other words, that is different from the conventional human leg joint? What sort of footfall patterns would be most efficient for a quadrupedal machine? Nature has evolved more gaits for quadrupeds than we find for bipeds, and they change based on speed: walk, trot, canter and gallop. How would a quadrupedal tank move through these gaits, and have you designed articulation which allows for them?

Howdy Tom,

yes all important considerations indeed. ReneAugustus's link was for BostonDynamics robot Big Dog currently in development for the US Army:

[link]

Rene prob missed my noting it in the posting as it directly influenced the look of the legs on the tanks and even some of the FOILs. So indeed I did consider the articulation movement and style of walking. What's cool about Big Dog is the legs are covered and give this creepy sense of skeletal shapes underneath and adds an unsettling feel when you see it in motion:

[link]

Now all said regarding the issue of engineering something bigger, so far we've yet to see a real world piece of walking artillery or legged tank. I expect there are a few logical possibilities as to what we might see though and there are plenty of working robotic examples only smaller. A spider or crab like leg articulation (which is the theme of the tanks here overall and most fictional walker tanks follow) is one of the more logical possibilities as you'd want the tank to be able to slip into a low profile and center of gravity for firing. Clearly the lower it can go the more stable it would be with legs, looking at it from real world concerns of course. The real hurdle beyond the technical engineering issues (which they've pretty much sorted out at this stage in working concepts) is weight. Weight would be a huge problem for walking tanks and this brings us back to a little fiction and fantasy :)

For fiction you can get a bit more playful and I tend to allow for that but still the basic concept for these tanks follows practical function actually more than being aesthetic driven (where the more fanciful part comes in is an antigravitic assist for weight concerns, so they don't sink into the ground when mobile. There's some narrative reasons for this as well). Though yes, these guys I wanted a clear tank look and nod to WWII armor, it's a fun troupe in this genre :) I do have a few cool more animalistic quadrupeds pending but they're smaller beasties.

Danke for the insightful comments, all excellent points Tom. This kinda stuff is a lot of fun considering there are so many real world examples actually out there now to refer to.
