I don't know if any of you are in the movie I've seen those humanoid mechs Feel very handsome They're still fighting hard. But you know what? The truth is, we've all been duped by those robo-movies Like in Pacific Rim and Transformers The movement is tens of meters Even giant mechs hundreds of meters high The soldier is here to tell everyone Humanoid mecha is actually the most wrong design The giant mech is the wrong of the wrong It is far less practical and rational than beastly or insect-shaped mecha And why would a soldier say that? Don't worry. We'll talk about it step by step mecha Full name "Mechanical powered armor" The root cause of this is the human imagination about the future If we're going to talk about the origins of mecha Japan, then, inevitably comes up Because the word It was first proposed by Japan Actually, After World War II technology Because Japan's military technology was severely damaged during the war So, after the war, there was a lot of focus on advanced technology And an obsessive fascination with giant machines In addition, science fiction often has a very close connection with war So much loved by the Japanese people The now world-famous Astro Boy It's from this period Can be said to be the originator of Post-war Japanese science fiction And mecha this high combat effectiveness, high-tech setting It was quietly born in this period However, Today's mecha didn't start with Astro Boy.
It's another 1950s Japanese production, Iron Man 28. It is a comic book published in 1958 by Tesplendor Yokoyama It was later adapted into the first giant robot animation in Japanese animation history According to the description in the work The machine is 18 meters tall 31 tons of It has 100,000 tons of output horsepower A pair of iron fists can hit a million tons of power Can sweep everything away with ease The protagonist of the work is shotaro Kaneda, a young detective You control it by remote control This setting not only opens the way for robots to be controlled by humans It was also an early form of mecha Since then This huge mechanical armor became popular It is one of the core contents of all kinds of science fiction works today For example, mobile Gundam Warrior, EVA today And all kinds of mecha creations from around the world Are deeply influenced by this idea In the current active equipment of various countries Caterpillar eoD robots and drones Most countries do have equipment A tracked combat robot carrying machine guns A number of countries are experimenting Even multi-legged robots There are individual countries that have been working on it Take, for example, eagle Jam's Spur robot dog It is now serving in some armies Compared with Although countries say they are working on it Humanoid mecha, however, are not known to have entered active service At least according to current information Robots equipped by different countries Or caterpillar Or wheeled At most, a few commercial companies are developing multi-legged robots Humanoid robots have had little success Not to mention those giant mechs that are going to be war machines So, what are the problems with humanoid mecha? Since it's a humanoid That, of course, is based on people But are humans perfectly balanced? It's not From thousands of years of human evolution People have made a point Four legs are better than two Better on four legs than on wheels Someone here might want to talk back to the soldier Doesn't the kangaroo have two legs, too? Isn't it perfectly balanced? is Kangaroos do have two legs But she also has a tail that helps her balance It's a third leg of a different kind. In addition Let's just take a step back The reason why humans can use two legs to achieve a steady walk That's also because of the human brain It controls tens of billions of computationally sophisticated nervous systems To make sure your legs are moving smoothly This is extremely difficult to do mechanically Today's electronic systems serve daily life just fine But if you want to mount it on a humanoid machine And to achieve the coordination and cooperation of each system It's almost impossible to achieve Although efforts are being made worldwide Humanoid mechs can walk like humans Take Britain's Ameca Claimed to be "the world's most advanced humanoid robot."
It is already possible to mimic human expressions But it is still lacking in walking However, There are also successful cases Take Boston Dynamics, which is owned by Google They developed "Altas ii" bipedal humanoid robots He already has a good walking ability Not only can you run, crawl, and jump And he can do complex moves such as moving things and doing back flips Even in the face of mountains, forests, snow and other extreme terrain Also can basically realize free walking Even if I fall to the ground You can get up on your own His balance is remarkable But the second generation Altas It's just a bipedal robot about the same height as a human If you want something like Pacific Rim That often dozens of meters, hundreds of meters high giant mecha also has such ability Water with today's technology Almost impossible to succeed In addition Having balance is not the most important thing More importantly Similar to the Pons Link, the driver's neural connection system in Pacific Rim With the state of the art Soldiers can be sure of that 100% In the movie Mecha pilots are connected to each other by a "spinal clip" mounted on their backs The ai will then read the human brain wave data And create a virtual brain consciousness on the mecha's main computer The driver wears a "circuit lining suit" covered with circuit sensors. Transmitting the brain's conscious commands and actions At the same time to the mecha to execute The science fiction technology is simply not possible at the moment At present, the most that has been achieved is to control the manipulator by wearing sensors in the palm of the hand But to achieve the almost delay-free sensing speed of Pacific Rim And it takes two pilots to work together It's almost impossible then What if the joystick is used to drive the mecha? This assumption is not to say no But put the cart before the horse Because if you use sense of operation That's one of the biggest advantages of a mecha -- its flexibility would be greatly reduced You can't do anything as delicate as you do in movies or anime It's like you're flying a machine and punching someone Is this possible with a joystick? In addition Not to mention the difficult moves you make in battle Then there's the question of the humanoid's center of gravity In humans, the center of gravity is usually 7 cm in front of the upper margin of the third sacral vertebra on the median surface of the body But it depends on the posture The center of gravity will also change The same goes for the mecha Want to keep the mecha's center of gravity steady in action or battle It's a tough question Let alone being attacked by an enemy If you can't even stand How can it be put to use? No matter what the device is If we want it to work The first thing is to prepare enough energy for it So what should humanoid mecha use for energy? In this regard, we can first look at The energy of Gundam As one of the most influential and oldest Japanese manga Gundam's energy Settings are more scientifically based There are no mysterious powers that cannot be explained It's not like the EVA body The source of its energy is not at all clear Looks like it's using electricity But when the soldier looked behind him From the first machine to get permanent power S2 mechanism And no. 3 doesn't need cables The organism of EVA should be a living organism related to the apostle Electricity is not its only source of power Its function may be merely to start things up Or restrict the use of the body such as violent walking Just wide of the mark And the energy used by gundam in different periods is also different Gundam Seed, for example, is mostly electric A small part is nuclear power In Gundam UC, nuclear power is widely used Later as high as 00 in the body Using a pseudo-sun or GN solar furnace It is also the nature of nuclear energy And then there's the Marvel Universe Iron Man's Ark miniature nuclear reactor To say the In the movie This reactor accounts for half of Iron Man's combat power Then there's the Mecha from Pacific Rim It's also powered by a nuclear reactor The joints are powered by diesel engines In the few cases the soldier mentioned above Batteries, nuclear power, these are all common sources of energy in the world today But in gundam and Iron Man Its battery and nuclear technology would certainly be much more advanced than it is today Especially the use of nuclear energy Can only say that Nuclear power as the most powerful power source in the hands of mankind Therefore, it is understandable that it has become a "panacea" in film and television but Have you ever thought about that Although g.I. said something about a small nuclear reactor But that's also relative to the mecha Real operating systems are extremely complex You have to be very careful It is necessary to always be on guard against the consequences of nuclear radiation After all, in the event of a nuclear meltdown on the battlefield It's not just the other side that suffers You could get friendly fire on your own home See here, some old iron is about to ask What's wrong with precision? Doesn't more sophisticated mean more powerful? It's not The mecha is sophisticated at the same time It also means that its fault tolerance rate will be greatly reduced Humanoid mecha created by modern human technology The machinery is bound to be extremely complex The failure rate is high Poor maintainability And it's expensive Plus the vital parts For example, the cockpit, power sources, etc. must always be above the center of gravity So in case you get shot At the same technical level It would need extra armor to protect it The result is to maintain engine power This in turn improves the performance and strength of the leg unit But in order for the mecha to walk on two feet There are bound to be complex software drivers and balancing devices This leaves the mecha vulnerable to emP weapons In addition Operating weapons by hand is an attempt to increase the universality of arms And modularization It also leads to complexity and reduced reliability in mecha design Take an example If the mecha's hands are designed like a human's There are ten fingers The advantage of this design is that The ability to switch weapons by grabbing them with your hands at any time Of course, It can also be used to catch enemies and other objects But have you ever thought about it The mechanical joints corresponding to the ten fingers are extremely complex So the failure rate can be incredibly high Old-timers can imagine a scene That is a dozen dozen dozen suddenly a finger "cramp" So as a weapon of war Designing ten fingers just to grasp things is obviously very unreasonable Say it to the soldier What weapons would you like to be equipped with He could have welded to his arm Instead of designing ten extra fingers to grab a big sword or a big gun So what does that mean? They were humanoid mechs armed with big swords and guns Actual combat may not have a welding of the same equipment of the beast mecha In addition Be the opponent of the mecha At the same level of technology A solo confrontation would be at a distinct disadvantage Because the opponent can strike at the mecha's weak spot For example, individual traps can be designed for bipedal walking defects Targeting structural weaknesses is the use of anti-equipment sniper weapons to hit key areas And then there are those powerful missiles All it takes is one round to destroy the mecha's joints Then it's about half as good as it gets It's like a tank with its tracks blown out All that's left is a sitting duck This is in response to the characteristic of humanoid mecha that can be easily paralyzed Causing the enemy to create a huge logistical strain without having to destroy it It's like the Cold War HKG11 assault rifle developed by Heckler The elaborate interior of the gun It's a headache for all the support staff There are so many parts in this thing The gun, though, relies on absolute airtightness to prevent dust But in practice there are too many uncertainties There is no guarantee that it will never need maintenance No wonder people say the G11 is a watch and not a gun And how much more Mecha defensive equipment is unlikely to evolve faster than offensive weapons And hardly any stronger than assault weapons This point is not obvious in the era of cold weapons But since the era of hot weapons The lethality of all kinds of weapons is geometrically increased Like today's body armor and helmet If it's a small caliber gun that's no problem But with all those high-powered assault rifles and sniper rifles Well, that's all there is to it Then there is the development of anti-tank missiles Its armor penetration is always better than the tank's defense The scariest are today's nuclear-armed intercontinental ballistic missiles You can only intercept it during takeoff The missile is traveling at a slower speed Most likely to be intercepted And then it enters the atmosphere phase of flight Icbms will fly at speeds in excess of Mach 20 It's the final final strike Its speed will exceed Mach 25 at least Even the US and Russia today There is no 100% certainty of a successful interception There have been experiments in the United States With icBMs as the standard In the case of 10 missiles Eight or nine missiles will still land The highest interception success rate is only 20 percent It's worth mentioning here Nuclear weapons, weapons of mass destruction As long as the interception success rate is not 100% So how much interception is pointless Because even launching a hundred Only one exploded successfully Can literally turn a city into rubble Taking the lives of millions, perhaps tens of millions I'm going a little far Let's get back to the point There's probably a lot of old-timers here who think the mechs are backed up by advanced technology There must not be so many weaknesses But just so you know Cutting edge technology available to the mecha under the same technological conditions It will definitely be used on fighters and tanks first Because of the same skill level Planes and tanks must have less structural complexity than mechs It also has a better cost-effectiveness ratio In material selection Mechs are distinct from armored vehicles To have extreme flexibility The selected material must be good enough in strength and toughness Because the mecha will drag the whole body when moving A behemoth dozens of meters, hundreds of meters Even raising an arm is not an easy task Take Pacific Rim 2 for example Its height reaches 81.8 meters
It weighed 2,004 tons If the material does not pass muster Do you think it can stand up? In addition The lack of strength of the material will result in the mecha being unable to withstand strong impact Low toughness can easily lead to metal fatigue Old iron people who know something about the material may be more clear The strength and toughness of metals trade off Any of a number of alloys developed to suit certain engineering applications Is to have the same toughness as strength Or the strength of the toughness Both are hard to achieve today And the strength of the mecha material determines its shock absorption capacity to a certain extent That's the countershock pressure Soldiers take body armor as an example The strength of a body armor against a gun bullet As long as it's not a high-caliber weapon Basically, it won't be a big problem But a gun bullet carries a lot of force Countershock caused by impact on body armor The wearer might not feel so good So good body armor can effectively reduce or eliminate this effect But with a humanoid It's up against heavy weapons The backshock from the impact is also stronger If there's not enough shock absorption The pilot could have been killed right there Not to mention the constant output of fire In summary, they want to build humanoid mecha Not only is the efficiency ratio extremely low with today's human technology And it doesn't have much practical value In addition, we need to consider the use of sensors and artificial intelligence And logistical maintenance Making the humanoid appearance incompatible with the large body shape We can only achieve twice the result with half the effort Especially in defense The joints of the mecha are weak spots It's very easy to malfunction from the slightest attack This is nothing compared to fully enclosed vehicles such as tanks or armored vehicles If you really want to build a mecha The soldier thought it was better to make a beast or a worm At least one leg won't incapacitate you Of course, This is not to say that the humanoid is useless On the contrary The real strength of the humanoid mecha Lies in its totipotency Give it wings and it goes up You can get into the sea with a different propeller It's not slow to put a few wheels on But at the end of the day these are all generalizations The place where humanoid mechs are most needed is not on the battlefield It's about exploring the unknown So the soldier decided Before the turning point in human destiny and technology Humanoid mechs don't make much sense in war But it looks like smart armor like Iron Man Quadruped, wheeled Or crawler support robots are definitely going to be developed And in this respect There are investments all over the world If it comes to space war I want to Why don't you buy more laser guns and stuff when you have the money to build mechs Trying to stay human in a vacuum This is probably because of Japanese belief This point in the animation that there is no problem After all, each world is set differently But if you really want to realize the human dream of steel Gundam in reality To become a mechanical superman and drive under heavy fire The idea is a dead end After all, How narcissistic does a human have to be to feel physically fit to fight? But even though the Gundam dream is broken But at least the Iron Man dream is something to look forward to Mark armour is by definition portable, wearable armour It is a kind of mechanical transmission and electrical components And the exoskeleton auxiliary equipment And it's not a fantasy In real life Similar exoskeletons already exist It's just not as heavily armed as Mark armor More is to stay in the auxiliary power of this piece High-end prosthetics, for example The United States has announced an assistive robot arm It was fastened to the soldier's waist Can help soldiers with guns or bulletproof shields Can effectively reduce the burden of arms Make sure the gun is stable Can easily lift a 12-kilogram M240 machine gun And this third arm is actually quite simple This is the transfer of weight from the arms and shoulders to the lower limbs And Lockheed Martin's HULC human weight-bearing exoskeleton It can carry up to 90 kilograms And the soldiers put it on They can carry up to 90 kilograms Traveling at four miles an hour for an hour Sprint speeds can reach 16 kilometers per hour Exoskeletons increase the load and speed of infantry That means firepower, protection Improved battery life Of course, this is not about soldiers fighting RPGS with their bare hands I'm going to do some heavy protection Examples include the head, thorax and upper limbs Makes it resistant to 12.7mm bullets Abdomen can withstand 7.62 The rest will take a stray bullet or something And with the help of the exoskeleton Infantry will most likely use 12.7 or even a small number of howitzers as their main weapons Or at the same time as a single person carrying anti-tank weapons Still has far more firepower and supplies than regular infantry If you add a battlefield situational awareness device Then exoskeleton soldiers are qualitatively different from ordinary soldiers So the soldier's point is Exoskeletons improve infantry in all directions That's why it's a must At least the accumulation of technology is correct And if the final cost can be controlled Then it is not a problem to equip large numbers of troops But for now The biggest bottleneck to exoskeleton armor is power Most of today's exoskeleton armor runs on electricity If you use internal combustion power, the overall weight will increase And power this aspect also has to consider its endurance problem HULC, for example, is powered by two 3.6kg lithium batteries Can only support their work for an hour And Iron Man's Mark Suit Is the pinnacle of individual exoskeleton armor It uses tiny fusion batteries You don't have to worry about power at all Its armor is made of superhard alloy Can be hard against tank guns Except for being able to run and jump Supersonic flight is no problem If there is anything wrong with it There's an energy shield missing Look at the Chief chief's Hammer powered armor With the shield on, you'll fall straight out of space and If in the future the exoskeleton energy problem is really solved I think small electromagnetic rail guns are not far off After all, there's a lot of power You can use the recoil of a pistol to generate the kinetic energy of a large-caliber machine gun The sniper rifle is even more direct to the medium caliber cannon penetration There's nothing to stop you from 200 meters but tanks And its close impact may even cause plasma high temperature damage If tanks and armored vehicles use the same technology That's even scarier According to the recoil the tank can withstand I'm afraid it's firing pure light brake energy I can shoot straight out of gustav's cannon And in rapid succession Except for the exoskeleton Nanorobots are another future military development In the nanoworld The car is the size of a grain of rice Helicopters only have 400 milligrams The father of the US Hydrogen bomb predicted it back in the 1980s Which country is the first to master nanorobot technology It is certain to dominate the world military field in the next century Theoretically Nanorobots are masses of atoms and molecules assembled in a certain order A miniature device with a defined function Mainly powered by solar energy and radio waves So in terms of manufacturing Biomolecules are the most abundant nanorobot components in nature Physicists have always modeled biological principles to build clever machines This is what we call bionics Since the discovery of scanning tunneling microscopy and carbon nanotubes Countries set off a boom in the research and development of nano-robots One of them is worth mentioning This carbon nanotube thing Its quality is one-sixth that of steel of the same volume But it's ten times stronger than steel This is why it has become a hot topic in nanotechnology research Professor Smalley, a Nobel Prize winner in chemistry, agrees Carbon nanotubes will be the material of choice for the best fibers of the future It will be widely used in ultramicrowires Ultra - micro switch and nano - level electronic circuit In 1990, Bell LABS in the United States has succeeded in creating extremely small nano-robots The robot is the size of a flea It's made up of gears and turbines and microcomputers Its components are as small as dust in the air The nanobot has attracted a lot of attention since its debut Not long after The University of Utah and the University of California in the United States have also developed several nanomotors In 2000, The world's smallest molecular motor has been built at Bauston University The motor is made up of 78 atoms And at the same time Japan and the Netherlands have also developed another kind of molecular motor that can be powered by solar energy It can be illuminated by light Continuous rotation Molecular motor is the core component of nanorobot It could power molecular machinery of the future Since then Research on nanorobots has never stopped Countless nanocomponents are being developed These nano parts and the engine and other actuators are assembled This is a useful micro-system Toyota, for example, has built a car with tiny parts the size of a grain of rice And a tiny car that works The University of Tokyo has made a tiny bionic insect out of silicon The insect can already fly several centimeters The future is perfect for military applications so Soldiers believe Future military power and future wars It's all up to one country to develop new weapons Content of science and technology There will be no return to a war that relies solely on human sea tactics now Military nanorobots are also coming into view Its size Ranging from tiny grains of sand to hummingbirds They can infiltrate key local military units in many ways The headquarters, the Arsenal Secret base or something. Carry out reconnaissance activities against them or directly attack the target Like detonating a target with special explosives Disrupting local electronic equipment and computer networks These nanobots can also act as sleeper agents Hidden in an enemy host device To quickly disrupt local combat systems Sandia National Laboratories, USA I've worked with insect robots that are centimeters to millimeters in size The robot will mainly be used to spy on nuclear weapons facilities stored in local areas And the inside of the manufacturing plant And because the insect robot is so small And usually has only one detection capability Therefore, it is necessary to deploy a large number of insect robots capable of analyzing and judging And by combining their data To determine if the target is a weapons plant or a fertilizer plant And here's what's even more surprising Other countries have developed tiny spy robots that look like jellyfish or fish If you put explosives on this robot We can attack a submarine anchored in a naval harbor Of course, the amount of these charges must be small It doesn't compare to torpedoes However, it can be used against enemy submarine sonar and other important parts Thus delaying its entry into the war The smallest military nanorobots so far are tiny sensors It can be scattered on trails On a highway or in a field Interconnect It forms a network of sensors When people or vehicles breach the electronic network formed by these sensors The sensor reports the information to the monitoring host It is summarized and analyzed And the operator can depend on the size and speed of the object as well as its mass To identify the best guess And why is it possible to guess That's because cameras and camcorders at smaller levels are not yet available We can only rely on sensors A professor in the United States once made a video Introducing a slaughterbots killing drone It can fly with AI intelligence Small explosives inside After the face locator Rush to the target and detonate the explosives Achieve one kill On him Wide Angle camera, sensor Facial recognition has everything The entire flight required no human control On AI all Just input the target's image information into its body He'll be able to pinpoint his target The recognition rate is as high as 99.9%
He had three grams of enriched explosives in his body After a high speed dive A single impact could easily destroy the human brain And it will find the target location by automatic positioning Can be through the cooperation between the types of work To complete the assault on the target imagine If you put a bunch of these nanites into a city The consequences were not too terrible Of course, maybe a lot of people scoff at this video I thought it was a simulation But the nanobot in this video is more than just a conjecture It's a combination of what we already have and how we can scale it down At present, various military powers are also actively engaged in the research and development of nano-robots And have developed at least dozens of components for nanorobots According to some experts Military nanorobots are expected to be out of the lab by 2025 Except for the way the video imagines fighting Nanorobots could find their way into conventional weapons technology By improving the manufacturing materials, production process Charge system or guidance system and other modes of transportation and storage So as to improve the tactical and technical performance of traditional weapon technology and equipment Enhance the killing effectiveness of traditional weapons Secondly, it can also develop combat methods against human combat means For example, developing nano-sized devices that can stick to hands and feet As for the later poison or the deep penetration or something I won't go into that Imagine for yourself And besides the nanites Nanotechnology could also have wider military applications The biggest problem facing soldiers on the ground today There are not enough batteries and charging equipment to complete a task of indeterminate duration They need a battery that can be recharged quickly and used in a loop In 2010, Nanodevices, a company based in Ohio, has demonstrated one Supercapacitors that broke all storage and recharging records The device can store the capacity of a nickel metal hydride battery And it only takes a few seconds to recharge Its energy density per unit is the highest of any battery In addition Nanomaterials could also be used to make lightweight personal protective clothing There will be sensitive nanobots embedded in the suit It can repair itself on the battlefield And respond to changes in the environment and weather And nanotechnology can also be used for the development of artificial intelligence If the key to true artificial intelligence is to copy the human brain So it takes about 100 billion neurons and 100 trillion neurons to build For this work I can't think of anyone better suited than nanites And the Molecular Manufacturing Institute in California He's even envisioning nanobots the size of bacteria It will be controlled by a specific program Tens of billions of these robots could be distributed in the air When you give the order The nanites will come together Make any shape you want Sounds pretty sci-fi, right? With the advent of nano military robots The balance of forces in modern warfare will also change When the Nanodeterrence warfare Nano paralysis warfare and other new combat methods Will also appear in the war arena Except in the military sphere Nanotechnology is also the best tool for medicine Tiny nanorobots made of atoms It can swim in the blood vessels Eat the garbage that settles on the walls of blood vessels Or targeted to identify and kill cancer cells and so on So the soldier believed The implications of the development of nanorobots It may be as influential as the industrial revolution and the information technology revolution It could completely destroy mankind's military, industrial manufacturing Electronic information industry Medical etc. Go up a step So do futurists It is possible that future nanobots will reside directly in the human body The blood circulates throughout the body Be part of the human-machine convergence Researchers at the University of Pennsylvania in the United States in 2019 In a matter of weeks Created an army of millions of nanites The researchers fired lasers at the robot's solar cells to power it The solar cells then cause the front and back legs to alternately contract or relax The robot also has a walking posture This army can work inside the human body Such as delivering medicines on demand and maintaining human health The same Researchers at the University of Toronto in Canada have also developed a nanorobot powered by electromagnetism It can block tumor blood vessels So as to starve cancer cells or directly destroy the effect of cancer cells In the future This approach also holds promise for chemotherapy Cancer patients who have failed radiotherapy and immunotherapy Offer a new treatment All right, highlight this video 1 Humanoid mecha is cool But there's no need to make it Exoskeleton armor is the future Super soldiers like Iron Man It's not out of the question The large-scale use of 3 nanorobots It's gonna change the whole world So you have a lot of interest in mecha What do exoskeletons and nanobots have to say? Feel free to discuss in the comments section If there is a mistake, you are also welcome to point out So what else do you want to see? You can also post them in the comments section Soldiers will schedule it as soon as possible Well, that's all for today's video For more information Make sure you check in Let's be there for the next video
