See this is my point! If this falls apart what about the rest of it!!

[Borgar]

they work by suspension of disbelief hung just between their legs

I figure it's probably like walking backwards. The only difference is that you are pulling yourself forward instead of pushing yourself forward.

[Nathan Foxbane]

From a base mechanical function point, 'Mechs can easily walk. None of it seems to work with simple diagrams, but try modeling it. Yes the gyro stabilizes the whole thing. Now the actual problems would be building one and exactly how practical one would be. Provided the proper budget (read university robotics program expensive) you could probably build a working small scale model of some of the more reasonable designs.

Seriously, crazier stuff has been built. The one legged bounding robot modeled after a kangaroo for example functions just fine. And there is another with actuated pistons for legs that can do flips form standing and sprints rather nicely though because of the design it fails at standing still. So the ability is there, but building a war machine from all that is the tricky part.

There's the Sony bot that walk sorta jogs and can take stairs. Saw him at Disneyland. Really cool. So imagine him 1500 years or so from now only bigger and major advancements.

I recommend you avoid all forms of science fiction and fantasy in the future.

mechs run like this catatrich here, so yeah it's sorcery.

The actions of the foot, toes and ankles in your IRL drawing are merged into the heavily articulated foot of the mech.

Also, yes there is a gyro in every mech.

[BLUPRNT]

I can see it just by looking at it. But the whole Mech idea in all is just "wut the".

Did I mention the chicken walkers just look cool.








Don't ever let go of your imagination or you soul purpose of being human is gone for good.

Do you see the problem I have here? The Timber Wolf is missing like, a whole essential leg part

(it's the one between the hip and the knee)

[Sorho]

If you want a reasonable explanation for things that happen within a science fiction game/movie/series you;re going to go through life terribly disappointed.

[Kerensky The Last Mechbender]

I mean I don't know what to tell you if you don't know how a leg works? Like, a lot of vertebrates have legs. Of the things one encounters in life, A Leg is a pretty common thing I think? I see them all the time I have two!

[Kerensky The Last Mechbender]

The Atlas no problem! It walks like A People. But the birdy ones are just bonkers imho.

Try modeling just the hips and legs and moving it by hand. It works fine. As pointed out earlier it is not much different than you trying to walk backwards. Same three point articulation. Digitigrade critters get all the luck because they have a fourth point.

Whoah whoah whoah hostile much jeez

mech legs work like the rest of the Mechs : RAINBOWS AND MAGIC!

That is internal and not observable without removing armour, like the inside of your car's transmission. They are shorter than the diagram length (for knee to hip) as mechs do not have the same range of motion.

Also, Gyro+Neurohelmet that translates the balance sensations of the inner ear to help keep a mech upright.

From Operation Excaliber

"The neurohelmet provided that link, feeding a variety of data input from sensors all over the 'Mech's body to the pilot through his audio nerves. Since the inner ear was closely associated with the human sense of balance, it was possible to let the pilot actually feel the attitude and balance of his 'Mech through the helmet's feed. It was impossible, in fact, to pilot a 'Mech without that balance feedback; without it, there was no way the pilot could sense the loss of balance and thus control the motion and attitude of a 'Mech trying to run, to jump, or even simply to walk."

Also this was the reason Grayson Carlyle lost the ability to pilot a mech.

"But with all that medical science knew, it still couldn't stimulate dead or severed nerves and make them grow, and a MechWarrior needed both left and right audio nerves to translate the signals from his neurohelmet into something his body could sense as balance, enabling him to pilot a 'Mech from a tiny cockpit ten meters off the ground and not fall flat on his BattleMech's face.
"I'm sorry, Colonel," Medtech Ellen Jamison had told him in the recovery room back at Castle Hill. "There's just nothing we can do. The nerve damage in your left ear can't be repaired. Without it, I don't think you're ever going to be able to pilot a BattleMech again.""

I see no problem: If humans can walk reverse (i can do that - i can even run so) Mechs can walk with reverse mounted legs - it is that simple!

Bees can't fly either aparently.

It is well-known that a scientist (supposedly) once said that physics (or science) shows that a bee can't fly (or maybe that a fly can't be?). Bees do fly, by the way. This is a popular example of how stupid scientists can be. It is hard to disagree with that. There is some small amount of truth to the statement that a bee can't fly (see addendum, below). But, the statement demands to be misinterpreted, and that is far from being scientific.

In reality, an aerodynamics expert in the 1930's stated he couldn't explain how bees fly, given the knowledge of aerodynamics at the time. That's not the same thing as saying bees can't fly. Just wanted to throw that out.


As to the walking, I agree, it's just like a human walking backward. The mech just has to "fall" foward on the supporting leg rear leg, then land on the other leg that has been moved forward.
