      Starting from plastic models of their favorite mecha, the Japanese have a genuine interest in robotics. The anime and game industries are big factors in Japan's advances in Robotics. Because of mainstream interest in mecha, especially Gundam, University clubs and hobbyist start huge projects on trying to replicate the cool mecha seen in anime.

      Contrast to Robot Wars with wedges slamming each other (which I find to be quite monotonous and repetitive after the first few times), I believe that the path the Japanese are taking -- bipedal robots which are more versatile -- will benefit mankind in terms of usefulness and application. Heck, even the Japanese version of Robot Wars is much more entertaining to watch, with the robots going through various attack patterns. Check it out here [impress.co.jp]

        You're right. There's even a prime-time family show over here (completely unrelated to anything techie) that has a robot-walker battle segment in it where amateur hobbyists duel it out with robots that would put the "wedges" to shame. Mom, Dad and the kids all turn up to control or cheer on the beast that they've been furiously developing in their garage. Their robots even do funky kung-fu style moves (albeit slowly!), or have 'gloat' manouevers so that they can do a little dance after they've knocked the other guy off the arena.

        A few years ago when the dotcom crash blew apart our industry I nervously accepted a position in Japan and headed out here not really knowing what to expect. I can honestly say its the best decision I ever made. I've never regretted it for a single day. I'd recommend it to anyone.

      That has the advantage of 6 legs.

      The problem is that we do not have any mechanical systems that can move rapid enough and accurate enough to mimic biped standing walking and running, espically in a 12 ton mecha form. as soon as someone invents that then your desire would come true in the form of forestry and construction equipment. They would KILL for a machine with the agility of a biped and the speed of a wheeled vehicle.

      the human legs are insanely accurate and fast devices, performing tons of micro adjustments every second. Look at a master of karate, he/she can kick so fast it looks like a blur yet stop their foot 1 inch from your face. computer technology is fast enough to handle that processing but there is no high strength mechanical actuation systems that can.

      and honestly mechanical systems are still very much primitive with only small advances because there has been no need for high speed, high strength, high acuracy yet.

      Disclaimer: I'm a retired real-life Armoured officer - and incidently, a former hard-core Battletech (board game!) player.

      Sadly, there's a few reasons why we're unlikely to ever see 'mechs striding the landscape:

      1) Vulnerability. Modern anti-armour weapons, especially guns, are insanely powerful. The 120mm gun in the M1A2, when equipped with the latest APFSDS ammo, has a muzzle velocity of over 1800 m/s, and a penatrative capacity of 960mm of Rolled Homogeneous armour - yes, nearly a full metre of solid steel. 1 cubic metre of steel weighs roughly 17,000 lbs

      Tanks get away from this by using armour that has greater protection capacity at thinner thicknesses, and heavily armouring only the portions of the tank likely to see fire - the turret, and the front of the tank. Tank commanders are heavily trained to use terrain and situational awareness to keep the armour pointed at the enemy. The punishments for getting caught "tracks up to the world" or "broadsides" were severe (although not as severe as what the enemy could dish out)

      Ideally, the only part of the tank visible to the enemy at any given point in time is the gun muzzle and the front of the turret.

      Effectively, the armour on the turret is worth about 800-900mm of RHA, and the glacis is between 500-600mm. The sides, top, and rear are much, much less - and the way that you generate those high effective thicknesses is through the use of super-dense materials like depleted uranium - lighter than the equivelent resistive thickness of steel, but still not exactly light.

      Your Atlas, even if the front arcs are more heavily armoured than the rear, stands so much taller than a tank that concealment and the use of terrain will be much tougher, if not impossible. That means that the forward arcs will have to be *at least* as well armoured as the turret of an M1, and it has a MUCH larger surface area to cover. That's going to weigh a LOT more than 100 tons.

      2) Mobility: Given the massive weight of the chassis (dictated by the armour it needs to carry) and the high ground pressure (dictated by the bipedal form factor) this thing is going to tear up terrain like nobodies' business. Tanks, with low ground pressure and (typically) rubber-padded tracks, still rip the shit out of roadways and open country. Your Atlas is going to be far, far worse. It will be difficult to move any number of them from place to place without transforming the roadway into an untraversable morass, and bridges will be right out of the question.

      Even assuming ideal conditions, mobility is still going to suffer. In a world dominated by line-of-sight projectile weapons, the proper place for a biped is on his stomach - or squatting. Soldiers walk and run, yes - but only for short distances. A quick burst of speed to the next position of cover, and then dive on your face.

      I doubt your Atlas will dive more than once.

      There are other reasons... but the basic problem is one of scale. Bipeds do not scale well past a certain size.

      Mecha started with "Giant Robots" which were really Japan's way of doing Sci-fi while tying back to its Samurai roots.

      When you actually look objectively at what a "Mech" would require, engineeringwise, and how it would pose risks to the human pilot, you realize how it will never become a reality, no matter how much R&D is spent.

      When you watch an anime battle with Mecha you see a lot of instances of these things doing hairpin turns and falling to the ground and bouncing around in a jarring fashion. Even today jet pilots can not pull certain maneuvers without blacking out from the G-forces. The kinds of things you see in anime would kill a human pilot instantly without some kind of magical inertial dampener technology. You'd be lucky if you walked away with just a case of whiplash.

      Secondly, we just don't have materials strong enough to build one of these. The joints especially are problematic. There is a real limit to how big these can be without being ultra fragile. If one of these were to fall over, not only would you need help to pick it up, but you'd probably also have to repair it.

      Third, power supply. All those motors need energy. How long do you think it will run off an internal battery or some noisy gas engine?

      I think it's great to try, but just because it LOOKS like something out of anime doesn't mean it's going to be anything close to as functional, and like I said, even if you could magically produce something that could perform like anime, without those intertial dampenders you REALLY wouldn't want to play around with it.

        Good analysis, but let me add just one point...

        Military vehicle designers have a name for big round blobs sitting on top of stilts. They call it 'a target'. There is a reason that both the Abram's tank and the Hummer are wide flat vehicles. You get the carrying capacity, and if a shell explodes nearby there is less chance of flipping the vehicle. The typical 'mech' design would be easily toppled and rendered useless with a simple hand tossed grenade, and that big round blob provide lots of area to absorb the blast.

          What you are saying is true for the classical type of battle, i.e. an open battlefield with mostly flat terrain. But this is hardly the case for today, where the air force plays the most significant role, and armies are called to fight in very diverse areas.

          On the other hand, it would be much easier for a robot like this to play hide-and-seek in mountainous areas, then instantly take off with a quick jump in the air and transform to an aircraft. It would also be possible to hide it inside mountain curves.
