The square cube law is not the reader's favor here, sadly.
Mars has a huge battle mech scene, because they can get away with way heavier bot designs at 0.38 g, and thousands of kilometers of inhabited desert on which to stage battles far away from structures that could get obliterated by shrapnel.

xXGundamfan0087Xx asked: Killian, according your long life labor skills with mechanics and vast experience on the field of technology, could you agree on the viability of humanoid robots of particularly giant size?
Killian: Ah, gigaweight upright walkers…. A beautiful dream that’s a royal pain in the ass to actually design… In battle mech competitions, gigaheavy walker mechs tend to be quadrupeds or dino-bipeds. Weight goes up exponentially with bot size, and the biggest bot classes often can't get back up after getting knocked down. Going gigaweight on top heavy designs with fiddly balancing like upright walkers just results in unimpressive, short, and expensive slap fights. There are some lighter upright walker competition classes in battle robot competitions, but they’re generally smaller than the average typ. The scale is less impressive, sure, but the fights are MUCH longer, and, in my opinion… waaay more exciting. Honestly, I prefer the good old fashioned tank types. Pete Pounder is my all time champ for Martian Mech Madness. Can’t go wrong with low center of gravity and a big fucking hammer!

big fucking hammer wins again!!!!!

Oh that’s so funny, I’ve had similar thoughts that in any sort of realistic setting, mechs would probably be more of a sports thing than practical. Like sure, humanoid tanks would probably be outperformed by an actual one in any sort of combat scenario, but could you imagine mech rallies? Infinite money.
That said, Killian makes a compelling argument for big fucking hammer.

Broke: mechas are useless for military applications!
Woke: engineering, support, and construction mechas!

Yeah, this is a pretty age old argument about whether or not real life battlemechs would have been viable.
In the end, yes gundams, chromehounds and armored cores are fucking cool as shit, but theres very little in the ways of good arguments for why you shouldn’t just take that same amount of resources and just build like a fuckton of tanks instead that can split up and cover multiple objectives, don’t require hundreds of years of engineering advancements just to not fall over, can still handle bad terrain because thats what threads are for, if a few of them blow up, the rest can still fight and they’re harder to hit cause they can make better use of terrain elevation for defense, not being the size of skyscrapers.
TLDR: yes, mech are cool, but if your setting is even slightly realistically grounded, then sorry.

is that v2 in there or am i seeing things?
also all hail big hammer

Well-played, both of you! xXGundamfan087Xx asking about “Humanoid robots of particularly giant size,” Killian immediately going to “gigaweight upright walkers” and the Martian battlemech competitions…
This is why we love AMAs!

Reminds me a little of a robot I saw. Wasn’t for battlebots but some similar competition. It was just a robot that used its whole body as a spinner and yet it was winning. Guess simple can be better at times.

The weight increasing with the cube of the size is not “exponentially”! :-3
[/OMP]
I guess that large long-legged humanoids still have problems with coordination, then. If they could jump with any precision … why wield a hammer when you can put almost your entire weight into a flying knee coming down on your opponent?

Gillian’s error feels in character, as he’s an engineer, not a mathematician, and I’ve seen sloppier terminology among my engineer friends. One of our jokes is that “infinity” is any number larger than you’d reasonably use. This eventually culminated in me saying “this is going to take me an infinite number of weeks to complete…. in this context infinity is two.”

I’m partial to a drum spinner, but I have to respect the classic Big Fucking Hammer

All hail the hammer!
