( On one chapter is 260, I made a mistake) (上一章是260,我又打错了) Next morning, leaf boat followed Chen Hao to arrive at some army base near Chengdu together, there, leaf boat saw he continuously curious domestic-made mechanical exoskeleton finally. 第二天一早,叶舟跟着陈昊一起来到了位于蓉城附近的某陆军基地,在那里,叶舟终于看到了他一直好奇的国产机械外骨骼。 According to Chen Hao in advance with the plan that the military communicates, this visit was divided into two parts, the first part is carried the exoskeleton to conduct the tactical maneuver demonstration by the specialized soldier, the second part arrives at leaf boat to go on stage to attempt. 按照陈昊预先与军方沟通的计划,这次的参观被分成了两个部分,第一个部分是由专业军人挂载外骨骼进行战术动作演示,第二部分才到叶舟亲身上场尝试。 On the target range has arranged various instruments, including operational vehicle, artificial obstacle, shell, stuffed dummy wounded person wait/etc, completely as item, performance for later demonstration mechanical exoskeleton. 靶场上早就已经布置了各类器械,包括作战载具、人工障碍物、炮弹、假人伤员等等,全部都将作为道具,用于之后展示机械外骨骼的性能。 The soldier who participates in the demonstration has built up, leaf boat stands on one side with Chen Hao, what side accompaniment is cadres in several army, they have not started while the demonstration, is reporting the later demonstration content to leaf boat briefly. 参加演示的军人已经集结完毕,叶舟跟陈昊站在一边,身旁陪同的是几名军队中的干部,他们趁着演示还没开始,正在简略向叶舟介绍之后的演示内容。 „leaf, the later demonstration mainly has several parts, we divide according to the branch of the services function, now is mainly the infantry, artillery, logistics and medical soldier these categories, what the role is biggest is in artillery, other branch of the services, in the use of mechanical exoskeleton temporarily are also not specially perfect, some tactical maneuvers are unable adaptive, particularly very intensive tactical maneuver, for example climbs up, jump wait/etc, the limitation is quite big.” “叶总,之后的演示主要有几个部分,我们是按照兵种功能来划分的,现在主要是步兵、炮兵、后勤、医务兵这几个大类,其中作用最大的还是在炮兵这一块,其他的兵种,在机械外骨骼的使用上暂时还不是特别完善,一些战术动作无法适配,尤其是高强度的战术动作,比如攀爬、跳跃等等,局限性比较大。” leaf boat nods, regarding such situation some of his early expectations, therefore is also far disappointedly. 叶舟点点头,对于这样的情况他早有预料,所以也谈不上失望。 Generally the present mechanical exoskeleton uses is two systems, the first system can call it the carrying a heavy load system simply, namely the retrosystem, its principle with the gear speed reducer and mix transmission chain technology of synchronizing wheel speed hump, unifies the real-time feedback of force, through dispersing dismantles in the servers of mechanical skeleton different position the stress of single position, transmits other body spots, or transmits the sole directly. 现在的机械外骨骼一般采用的都是两套系统,第一套系统可以简单地称之为负重系统,即减速系统,其原理是用齿轮减速机和同步轮减速带的混合传动链技术,结合实时力反馈,把单个位置的受力通过分散在机械骨骼不同位置的伺服器拆解开,传递到身体其他部位、或者直接传递到脚底。 But another system is the kinematic scheme, bases on the series connected elastic drive, is calculated the joint feedback of force after the mechanical impedance control system, actuates the high torque direct current machine to the machinery internal springing ---- Generally speaking is the spring conducts to reverse the stored energy, then using spring energy the accelerated motion that realizes the joint, the final result realizes to reduce effort and accelerate in the ordinary rate process. 而另一套系统是运动系统,是基于串联弹性驱动,由力阻抗控制系统计算出关节力反馈之后,驱动高扭矩直流电机对机械内部的弹性装置----一般来说就是弹簧进行扭转储能,然后利用弹簧能量实现关节的加速运动,最终的结果就是在普通运动过程中实现省力、加速。 Simply speaking, the carrying a heavy load system can make the user move a heavier object, but the kinematic scheme can make the user jump high, runs quickly. 简单来说,负重系统可以让使用者搬起更重的物体,而运动系统则可以让使用者跳得更高、跑得更快。 But the issue is, the complexity of kinematic scheme compares with the carrying a heavy load system is much more complex, particularly in again the stored energy speed, even if the power density highest, is over muscle density several times drives the driver, slightly will also be slow in the reaction speed in the muscle, therefore this caused when conducting the fast movement, the exoskeleton user will feel a slight lag feeling. 但问题是,运动系统的复杂程度相较与负重系统要复杂得多,尤其是在重新储能的速度上,哪怕是功率密度最高的、超过肌肉密度几倍的直驱驱动器,在反应速度上也会稍稍慢于肌肉,所以这就导致了在进行快速动作时,外骨骼的使用者会感受到一种轻微的滞后感。 If must describe this lag feeling, the best example is most people have played in school June first International Children's Day that three people of board activities, everyone's foot fixes on the long board simultaneously, before the movement has not achieved the synchronization, the detention feeling that person who first starts feels is the present mechanical exoskeleton detention feeling. 如果要描述这种滞后感的话,最好的例子就是大部分人在学校六一儿童节活动上玩过的那种三人一板活动,所有人的脚同时固定在长板上,在动作没有达到同步前,首先启动的那个人所感受到的滞涩感就是现在机械外骨骼的滞涩感。 However, theoretically, this postponing can also overcome through the training ---- Before this involves leaf boat, two sets of muscle memory issue that said. 不过,理论上来讲,这种延后也是可以通过训练克服的----这就又涉及到叶舟之前所说的两套肌肉记忆的问题了。 In his train of thought scatters, drilling in not far away target range has started, leaf boat takes back the mentality, starts to watch the drilling earnestly. 正在他思绪飘散的时候,不远处靶场上的演练已经开始,叶舟重新收回思路,认真地开始观看演练。 First the one who enters the stage is the artillery, sees only a stature not to calculate before the big soldier arrives at the ammunition box, grips the edge of ammunition box with the hand firmly, later makes an effort slightly, that length surpasses one meter ammunition box to be lifted with ease. 首先出场的是炮兵,只见一名身材不算高大的士兵走到弹药箱前,用手牢牢握住弹药箱的边缘,随后稍稍用力,那个长度超过一米的弹药箱被轻松抬起。 „This is the ammunition box of d30 122 millimeters artillery, the actual equipment 3 rounds, the bullet weight 22 kilograms, in other words he holds up to be close to over 70 kilograms objects being stress-free one time. And leaf you looks, unlike the previous generation mechanical exoskeleton, this exoskeleton has very big promotion in the flexibility and work error rate.” “这是d30型122毫米榴弹炮的弹药箱,实装三发,弹重22公斤,也就是说他一次性举起接近70公斤以上的物体毫无压力。并且叶总你看,跟上一代机械外骨骼不同,这一款外骨骼在灵活度和工作错误率上有很大的提升。” „Mainly was the man-machine interaction speed becomes quick ---- Because we replaced a stronger electrical machinery.” “主要是人机交互的速度变快了----因为我们换装了更强的电机。” leaf boat nods, he can see on the target range the movement of artillery, just like side expert said that compared him once in that in the news saw clumsily, the slow exoskeleton installment, the thing that this time he saw strove to excel obviously on are too many. 叶舟点了点头,他能看到靶场上炮兵的动作,正如身边这个专家所说的一样,相比起他曾经在新闻上看到的那种笨拙地、缓慢的外骨骼装置,这次他看到的东西显然要强上太多。 At least, artillery in carrying out his process of one set of movement, no link is specially mechanical, even the whole looked to give back to leaf boat a feeling of passing clouds and flowing water. 起码,炮兵在执行完他的一整套动作的过程中,没有哪一个环节是特别机械的,甚至整体看下来还给了叶舟一种行云流水的感觉。 The shell enters the chest cavity, but the soldier has not conducted the scene to fire, but continued to demonstrate other such as to issue in the plow and manpower towed howitzer and under the emergency conducts the operation of fast transfer to the artillery. 炮弹入膛,但士兵没有进行现场击发,而是继续演示了其他诸如下发驻犁、人力牵引火炮、紧急状态下对火炮进行快速转移的操作。 From these operations, leaf boat can obviously feel the strength of single soldier was enlarged, movement that some were impossible to complete, in their hands becomes relaxed. 从这些操作里,叶舟可以明显地感觉到单个士兵的力量被放大了许多,一些本来不可能完成的动作,在他们的手里都变得轻轻松松。 Afterward, the logistics is also mostly the same except for minor differences from the medical soldier's demonstration, the quick horizontal suspension stretcher that the medical soldier conducts the back actually makes leaf boat at present one bright, in that gadget extended dead to reach a deadlock the express box of delivery man body back to be the same probably, through the body of each part of locking gear automatic fixed wounded person, set aside both hands to the medical soldier, the outer wall also undertook part of protections. 随后,后勤和医务兵的展示也都大同小异,倒是医务兵背上的快捷横挂式担架让叶舟眼前一亮,那玩意儿伸展开来就好像死亡搁浅里快递员身后背的快递箱一样,通过各个部分的锁定机构自动固定伤员的身体,给医务兵腾出了双手,外壁也承担了一部分的防护作用。 However, in addition, leaf boat has not truly seen any new highlight. 不过,除此之外,叶舟也确实没有看到什么新的亮点了。 Waits for the demonstrations of these three branch of the services, the demonstration of Ye Zhou's long-awaited infantry combatant finally starts, sees only on the soldier in target range to carry the refitted exoskeleton, the back carries one not to know that model individual recoilless gun and a QW-12 individual air defense missile, very 95 light machine guns, in the hand take the ots-11 system ensemble rifle, the chest front are hanging various ammunition and other explosive materials equip, entire one is the firepower monster! 等这三个兵种的演示完毕,叶舟期待已久的步兵战斗员的演示终于开始,只见靶场上的士兵身上挂载着已经经过改装的外骨骼,背后背着一具不知道型号的单兵无后座力炮、一具前卫-12单兵防空导弹,一挺95轻机枪,手里拿着ots-11综合系统步枪,胸前挂着各类弹药和其他爆炸物装备,整一个就是火力怪兽！ The slightly extremely fat soldier runs on the target range in the individual firing positions, weapon 11 test fires, the distant place establishes the good target to be exploded crushes. 略显臃肿的士兵在靶场上奔走于各个射击位置之间,把身上的武器一一试射,远处设置好的靶子被炸得粉碎。 Sees this, leaf boat cannot help but somewhat sighed. 看到这一幕,叶舟不由得有些感叹。 For these years had not watched the development of army, never expected that their firepower insufficient phobophobias have developed this degree...... 这几年没关注过陆军的发展,没想到他们的火力不足恐惧症已经发展到这种程度了...... 4 types of weapons, in view of the medium armored ground targets, helicopters, the colony infantries and conventional infantries, each weapon can display important about respectively. 四种武器,分别针对中型装甲地面目标、直升机、集群步兵、常规步兵,每一个武器都能发挥至关重要的左右。 Especially that looked on heavy, long a little looks like Gustave's recoilless rifle, really how will be hard to imagine the rabbit to provide the individual rank this type of thing. 尤其是那具一看就不轻的、长得有点像古斯塔夫的无后坐力炮,实在是难以想象兔子怎么会把这种东西配备到单兵级别的。 After waiting to demonstrate complete finished, leaf boat also basically made clear the present this exoskeleton flaw point. 等全部演示都结束之后,叶舟也基本搞清楚了现在这具外骨骼的缺陷点。 Just like he thinks that the delay is the biggest problem, in the infantry full Guazai situation, carrying a heavy load of their whole body exceeds 60 kilograms, the carrying a heavy load system and kinematic scheme must the synchronous working, the coordination pressure that this creates is huge. 正如他所想的,延迟还是最大的问题,在步兵满挂载的情况下,他们全身的负重超过60公斤,负重系统和运动系统必须同步工作,这带来的协同压力是巨大的。 Therefore, this soldier , when conducting some fine movements for example to drop to the ground, crawl, surmounts and jumps, often seems extremely unwieldy. 所以,这个士兵在进行一些精细动作比如卧倒、匍匐、翻越、跳跃的时候,往往显得极为笨重。 After frowning thought a while, leaf boat opens the mouth to ask: 皱着眉头想了一会儿之后,叶舟开口问道: „Why can so many weapon stoppers to a soldier on?” “为什么要把这么多武器塞到一个士兵身上？” Director directly in same place. 身边的指挥员直接愣在了原地。 Why? 为什么啊？ This seems an issue that touches the soul, he has many reasons, but could also not say at once. 这仿佛是一个触及灵魂的问题,他有许多理由,但一时之间又说不出来。 After hesitating for several seconds, he says: 沉吟几秒钟之后,他开口说道: „leaf, our considerations are this, from the development direction of modern warfare, the battle distance has been in the unceasing move back in the process, shot dead from the 17 th century lining up, to the 19 th century 300 to 500 meters battle, has developed now, the battle range of light infantry has to the trend of out-of-sight development.” “叶总,我们的考虑是这样的,从现代战争的发展方向来看,交战距离一直处于不断拉远的过程中,从17世纪的排队枪毙、到19世纪的300到500米交战,一直发展到现在,轻步兵的交战范围已经有了向视距外发展的趋势。” „Therefore, based on this trend, in addition the speeding up of mechanized degree, in our whole believes that the high mobility and covert significance that pursues infantry individually combat element are not big, what is most important is the individual firepower delivers the ability.” “所以,基于这个趋势,再加上机械化程度的提高,我们整体上认为,去追求步兵单个作战单元的高机动性和隐蔽性意义已经不大了,最重要的还是单兵火力投送能力。” „We must achieve a soldier to attack the tank , to shoot the airplane, forms the entire function the combat element.” “我们要做到一个士兵既能打坦克、也能打飞机,形成全功能的作战单元。” „Must form such combat element, the amount of arms that a soldier can carry was very important...... you also to see, the result of finally presenting was this.” “要形成这样的作战单元,一个士兵所能携带的武器数量就很重要了......你也看到了,最后呈现出来的结果就是这样的。” „Useful?” “有用吗？” leaf boat asked curiously. 叶舟好奇地问道。 „Exercise that had from us a while ago, to be honest, was too useful. A light infantry arranges after achieving enough fire superiority, in matching reasonable direction, can definitely pose the significant threat to the traditional armored infantry company, we even have a class to wipe out the combat examples of opposite party 4 tank two helicopters.” “从我们前段时间进行的演习来看,说实话,太有用了。一个轻步兵排在达到足够的火力优势后,搭配上合理的指挥,完全可以对传统的机械化步兵连造成重大威胁,我们甚至有过一个班打掉对方四架坦克两架直升机的战例。” „Then is exaggerating?” “那么夸张？” leaf boat stared in a big way the eye, he had not known about the military, knows that the firepower regarding the importance that the light infantry battled, but he has not thought result that the fire superiority created exaggeratingly to this degree. 叶舟瞪大了眼睛,他并非对军事没有了解,也知道火力对于轻步兵作战的重要性,但是他没有想到火力优势造成的结果会夸张到这种程度。 The directors nod, replied: 指挥员点了点头,回答道: „Very exaggerating ---- Naturally, the individual cost is also very high, basically 2-3 soldiers were equivalent to a multipurpose car(riage). However, we actually do not care about the cost now, because the weaponry expensive/noble can also again the mass production, but personnel, if lost, that really did not have the means to supplement.” “很夸张----当然,单兵成本也很高,基本上2-3个兵就相当于一台多功能车了。不过,我们现在其实并不那么在意成本,因为武器装备再贵也都是可以量产的,可人员要是损失了,那就真没办法补充了。” „That was...... was truly good, I must first try your exoskeletons.” “那确实是......好了,我要先去试试你们的外骨骼了。” „Has prepared to you.” “早就给你准备好了。” Is saying, the director while led the target range edge leaf boat, to let him experienced the entire process completely, he has not arranged other personnel to assist, but made leaf boat put on the mechanical exoskeleton. 一边说着,指挥员一边把叶舟带到了靶场边缘,为了让他完整地体验整个过程,他并没有安排其他人员协助,而是让叶舟自己穿上了机械外骨骼。 In this process leaf boat has not encountered the difficulty completely, he discovered that this exoskeleton does in human factors engineering compared with is much better, the degrees of freedom of various joints he imagines have been the extremely fine degree, the most hard-to-control ankle and wrist/skill also made the full degree of freedom. 这个过程中叶舟完全没有遇到困难,他发现这具外骨骼在人因工程方面做得比他想象的要好得多,各关节的自由度已经达到了极为精细的程度,最难以控制的脚腕和手腕也做了充分的自由度。 This makes the entire clothing process incomparably smooth, in addition the control of intelligent system, each spot can lock after the confirmation automatically adaptive, from starting the clothing to fitting out to finish, altogether time not over 5 minutes of expenditure. 这使得整个穿戴过程变得无比顺畅,再加上智能系统的控制,各个部位在确认之后都能自动锁紧适配,从开始穿戴到整备结束,总共花费的时间不超过五分钟。 But the weapon carries the aspect also extremely to be user-friendly, may the movable support control by the arm inside control desk, presses down the corresponding mechanical button, gallows automatism spread will deliver position that can select. 而武器挂载方面也极为人性化,身后的可活动支架是由手臂内侧的操作台控制的,按下对应机械按钮,身后的挂架就会自动展开送到可以摘取的位置。 leaf boat tried to operate several times, started to move on the target range back and forth, even attempted to make the movements of several jumps, later he discovered, this set of operation logic must adapt really is not simple. 叶舟试着操作了几次,又开始在靶场上来回跑动,甚至尝试做了几个跳跃的动作,随后他发现,这套操作逻辑要适应起来还真没那么简单。 For example, according to the operation of intuition, after a jump only needs a leg, launches on the line, however in the heavy load condition, this exoskeleton were many a thermal energy storage process, this also caused a fatal issue: 比如,按照直觉的操作,一次跳跃只需要曲腿后展开就行,但是在重载状态下,这具外骨骼还多了一个蓄能过程,这也就导致了一个致命的问题: He has no way to jump in the moving process. 他没法在跑动过程中跳跃。 Is this point, seriously multiplicity that has limited the tactical maneuver. 仅仅是这一点,就已经严重限制战术动作的多样性了。 After using one, leaf boat basically summarizes the problem that this machine armor had. 使用了一圈之后,叶舟基本总结出了这具机甲存在的问题。 The movement delays, the thermal energy storage process to be long long, flexibility was still insufficient. 动作延迟长、蓄能过程长、灵活性仍然不足。 Therefore, „reason that after this causes to unload exoskeleton, will not walk” truly, before rather than Chen Hao, judges „movement strength feedback difference”. 所以,这才是真正导致了“卸下外骨骼之后就不会走路的原因”,而不是陈昊之前判断的“动作力量反馈差异”。 leaf boat turns back the target range edge, at the same time unloads the exoskeleton coordinatedly in while Chen Hao said: 叶舟走回靶场边缘,一边卸下外骨骼一边对等在一边的陈昊说道: „I confirm an extraordinary personality famous saying today: Without the investigation , there would be no right to speak.” “我今天验证了一句伟人名言:没有调查就没有发言权。” „What do you mean?” “啥意思？” „Yourself put on one to know, the basic reason of this exoskeleton was not the servo-link, but was the feedback of force system.” “你自己过来穿上走一圈就知道了,这具外骨骼的根本原因不是助力系统,而是力反馈系统。” „From feedback of force boost, at present we what use is the pure physical conduction, to playing a three people of board is the same, the following person must first feel the strength that you raise legs, can synchronize raises legs.” “从力反馈到助力,目前我们用的还是单纯的物理传导,就跟玩三人一板一样,后面的人要先感受到你抬腿的力,才能同步地抬腿。” „The delay of this process is longer, the movement logic difference under operation logic and normal state is bigger, the final result is, unloaded armor, will not walk.” “这个过程的延迟越长,操作逻辑与正常状态下的运动逻辑差异就越大,最后的结果就是,卸了甲,就不会走路了。” Hears Ye Zhou's words, nearby director nods again and again. 听到叶舟的话,一旁的指挥员连连点头。 „Right right! Is this issue! Our soldiers feed back also is mainly the issue in this aspect.” “没错没错！就是这个问题！我们的战士反馈的也主要就是这方面的问题。” On his face reveals the pleasantly surprised look, although does not know today the young people named leaf boat is what background, but from opposite party's performance, the big probability is the exoskeleton domain big shot, sends to solve the problem specially. 他的脸上流露出惊喜的神色,虽然不知道今天来的这个叫叶舟的年轻人到底是什么来头,但从对方的表现来看,大概率是外骨骼领域的大佬,专门派过来解决问题的。 Thinks of here, he is following close on asking: 想到这里,他紧跟着问道: „leaf, does this issue have the means solution?” “叶总,这个问题有办法解决吗？” leaf boat pondered the moment, opens the mouth to reply: 叶舟沉思了片刻,开口回答道: „I really am not this specialty, therefore in the concrete technical detail could not put forward too many proposals, but, I think that can start from two directions.” “我真的不是这个专业的,所以具体的技术细节上提不出太多的建议,但是,我认为可以从两个方向入手。” „First, takes the artificial intelligence route, records the sports of user through the CPU, makes the model the sole muscle and state of motion of muscle group, through unceasingly the data acquisition and machine learning, is achieved by the movement of artificial intelligence finally prerequisite muscle group -based sentences the next movement of user in advance.” “第一个,走人工智能路线,通过中央处理器记录使用者的运动习惯,将单一肌肉和肌肉群的运动状态做成模型,通过不断地数据采集和机器学习,最终做到由人工智能基于前置肌肉群的运动预判使用者的下一步动作。” „This logic was equivalent to martial arts saying that looked that the person had/left the move do not look at the hand, must look at the shoulder, the truth was the same.” “这种逻辑就相当于武术里说的,看人出招不要看手,要看肩,道理是一样的。” „But, the technical standards of this artificial intelligence request were too high, I estimated that in the short-term is very difficult to realize.” “不过,这种人工智能要求的技术水平太高了,我估计短期内很难实现。” „Therefore, I have an idea, although seems like very profound imaginary, but has basically realized to apply, moreover is using also the good idea it is said.” “所以,我有一个想法,虽然看起来很玄幻,但是已经基本实现应用、而且据说用着还不错的想法。” „You said!” “你说！” The directors closely are staring at leaf boat, probably for fear that he ran. 指挥员紧紧盯着叶舟,像是生怕他跑了似的。 leaf boat coughed, says: 叶舟咳嗽了一声,开口说道: „Builds the neural control system, jumps over the feedback of force directly, thinks after the electrical signal synchronization control mechanical exoskeleton.” “搞神经控制系统,直接跳过力反馈,用神经电信号同步控制机械外骨骼。”
