    How Practical are these things?

    So how practical are mobile suits anyway? obviously not very. any info on this kind of thing and how the world is developing technology for mech type things would be welcome. thanks in advance!

    The thing about it is, as a society we could probably develop a rather large MS similar to that of a Zaku or maybe even something from Armored Core. HOWEVER. The problem with that, is powering it. Shy of using a nuclear reactor, we don't have an effective way of powering such a large weapon, with something small. Energy sources such as gasoline or diesel would deplete way to quickly for it to be useful, and wouldn't be efficient space wise. And batteries is just out of the question. To power something that large, would take way to many batteries.

    So in my opinion, to really see an advance in robotics, we're going to have to solve the energy crisis we're currently facing. We haven't really had a breakthrough in energy containment in a few years.

    If you think about it you'd also need an insane amount of thrust to make even a zaku fly wouldn't you.

    Aside from technical limitations, there's another glaring issue that Mobile Suits face which is the straying away from conventional state warfare to the more asymmetrical.

    Mobile Suits would be a terrible, terrible design in any sort of reality.

    By standing up on two legs, they lose quite a lot of their balance. Truth is that one solid hit would send the things tumbling. And since they are standing so very tall, it is quite easy to hit them compared to something like a tank that keeps its profile nice and close to the ground.

    Furthermore, the majority of the surface area of a mobile suit is just wasted. It really doesn't contribute to mobility or firepower, it is just more surface area to be destroyed rendering the whole machine useless.

    Ironically what would probably actually be one of the best mobile suit designs is considered one of the worst-- the Guntank. The idea that the Guntank couldn't be used in space is just silly as there is nothing about a mobile suit having legs rather than treads that would make no gravity movement any easier-- one could put boosters on a Guntank just as easily as one could a mobile suit with legs and it would boost around just fine, if not better, than other suits since it wouldn't have those spindly legs that could be blown off.

    Of course, the Zeong would be a great design for space for a similar reason, but unlike the Guntank it makes sense that it would be pretty useless once in an environment with gravity.

    The quadraped wolf-like mobile suits from Gundam Seed would also be inherently superior designs to conventional mobile suits. 4 legs would give your suit superior stability, speed and maneuverability.


    Basically what I am trying to get at is that if one were to use the same technology that one has to use in order to get humanoid robot vehicles working, but were to use those same technologies in tanks or jets, the tanks and jets would have superior performance to a humanoid robot vehicle. Current vehicles are not humanoid not simply because of lack of technology, but also because they are a more efficient shape for vehicles and thus also vehicular weapons.

    The advantage of a bipedal body is that it can move for a long time over rough terrain that a wheel or tread would have difficulty going without using as much energy as a quadruped would use. But a lot of that advantage goes away when you make the body out of metal and ESPECIALLY when you scale it up to 20 meters tall.

    Yet we are working on a bipedal robotic frame for combat environments to aid and assist Humans. The main difference is that they are "Chicken Walkers". I know you have seen the videos of the combat robot that can do flips and jump over things but it is about the same size as a human, only slightly bigger.
    Like Atlas from Boston electronics

    Or the Disney acrobatic robots.

    So us being human and big is never big enough don't you think that some guy in a test lab at some think-tank for the military is already thinking of stuff like this?

    Well, in those cases they need something that can cross difficult terrain, not use a whole lot of power and has free arms to lift something up. But that doesn't mean it is the most efficient shape for strapping weapons to and having it shoot at things and get shot back at.

    Also, both examples there are smaller than human size.

    Do you know what happens when you increase something's size?

    Its power increases linearly but its weight increases quadratically.

    What that means is that if you built that robot twice as big, it could be twice as strong if you gave it enough power. But its own body would weigh 4x as much. At that point, given how shakey it looks already, it almost certainly won't be able to hold up its own weight.

    And that robot isn't even 2 meters call. All the gundams are 10x as tall and almost all are covered with heavy armor across the body and constantly carrying gigantic weapons. The thing would only have 10x the strength but would weigh 100x as much. It would absolutely not be able to move at all!

    Re: How Practical are these things?

    yes I rather intelligent when it comes to the physics of Size to weight and power ratios. I did find it a bit funny when in "Pacific Rim" they say things like 20 diesel powered generators with 100 ton cable reinforcements generating x yady yadda make up big words that sound good here... When talking about the make up and power plants of the Jegers. Those things are massive compared to a Gundam.

    But there are still people working on mechanical suits.

    Not only the power issue and size issue but MS joints would need a way to fail safe in that if power of hydraulic pressure is cut they need to not just fall over. you see that happen in the anime but it is really underplayed how much damage falling over would do to an MS. also anothe HUGE issue it controlling it in any way that would be useful enough to be justified. the human interface system would have to be worked out to a point where you could move it with nearly as much or as much precision as your own body. using pedals and sticks ising going to cut it. some kind of implant that sends and receives signals to and from the central nervous system while the pilot is in a sensory deprivation tank in the cockpit would be about as good as it gets. you would feel like you are the MS. realistically a power armor that is 10 foot tall or in that ball park would be useful. if you figured out how to power it and how to control it in a way that would give it an acceptable run time and able to move through rough terrain. they would make excellent infantry support. would be able to go places a tank cannot, would be great at punching through well defended positions. and war is 90% non combat, they would be good for filling hesco barriers, laying concertina wire. deploying mines, EOD, psychological warfare, Electronic warfare, recon, patrolling, ect ect. reactive armor and slat armor would protect them very well from RPGs. the new polyethylene armor would give them a replaceable multiple hit capable small arms level of protection on top of the steel armor they are made of. anti-personell mines would keep suicide bombers at bay. and there are all kinds of tech ou there to detect IEDs. the size is basically the only reason MS would be horrible in my opinion. what would be best is power armor that could go inside buildings, clear rooms and tunnels. its just our technological limitations that keep that from being our reality. would be like trying to imagine tanks in the 17th century.

    Also PJ Zakus dont really fly in atmosphere. its more of a rocket assisted jump.
