翻译人员: Hagar Abdelrahman 校对人员: sylvia feng

Exactly 12 years ago in a TEDx Talk,

12年前在一场TEDx演讲

I introduced my seven species of robot.

我介绍了我的7种机器人。

A unique three-legged robot called STriDER,

一个独特的三足机器人， 叫STriDER，

a wheel-leg hybrid robot called IMPASS,

一个轮腿混合机器人， 叫IMPASS，

an amoeba robot and many more.

一个阿米巴机器人等等。

Now, 12 years is a pretty long time,

现在，12年太多了，

especially in a cutting-edge field like robotics.

尤其是机器人技术这样的尖端领域。

How have our robots evolved during the past 12 years?

在之前的12年内机器人 怎么进化的？

What new species of robot have we built since then?

从那时候我们建造了什么新 的机器人种类呢？

Hello, my name is Dennis Hong,

你好，我叫Dennis Hong，

and today, I would like to show you our next seven species of robot.

今天我要给你展示 我们下7种机器人。

Since my last TEDx Talk,

自从我上次TEDx 演讲以来，

we’ve been focusing on the development of humanoid robots:

我们一直专注于人形机器人的发展

robots that look like us,

看起来像人的机器人，

two legs, torso, two arms and a head.

两条腿、躯干、 两条手臂和一个头。

Let me show you some of the humanoid robots

让我给你展示一些人形机器人

that we developed at our lab, RoMeLa.

在我们实验室——RoMeLa开发 的。

DARwIn is a miniature humanoid robot for research and education

DARwIn是一款用于研究和教育 的微型人形机器人

that we made fully open-source.

我们把它完全开放源代码。

(Laughter)

（笑声）

CHARLI is considered the United States’

CHARLI被认为是美国

very first full-sized humanoid robot.

最先的全尺寸人形机器人。

THOR-RD is for disaster relief applications

THOR-RD是为救灾应用

and Shipboard Autonomous Fire fighting Robot, SAFFiR and THOR,

和船载自主消防机器人——SAFFir 和THOR，

which uses this unique biologically-inspired actuator.

它们使用独特的受生物启发执行器。

And many more.

等等

I think we built more than a dozen different types of humanoid robots.

我觉得我们建造了十几种不同类的人 形机器人。

However, after more than a decade of humanoid robotics research,

不过，十几年的 人形机器人技术研究之后，

I'm starting to have different thoughts.

我开始有了不同的想法。

Now humanoid robots are important and they're great.

人形机器人又重要又伟大的。

However, they always fall down, they’re too unstable.

但是，它们很不稳定总是摔倒。

And they’re painfully slow.

也很慢。

Yes, these days we’re trying to develop technology

对，现在我们正在努力发展一个

that resolves these two problems,

解决这两个问题的技术，

but still, they are too expensive and they’re too complicated.

但是，它们又贵又复杂。

And most importantly, they’re too dangerous.

和最重要的很危险。

You do not want to be next to these big, heavy moving robots.

你不想靠近这些又大又重 的移动机器人

It might fall on top of you.

它有可能摔倒你身上。

So what do we do?

那，我们怎么做呢？

(Laughter)

（笑声）

Now, why is it so difficult to make robots walk with two feet?

那，为什么很难建造 用两条腿行走的机器人？

I mean, we do it all the time.

我们一直用两条腿走路

So once I wanted to throw away everything I know about robotics for a moment

所以我要暂时扔掉 我所知道关于机器人技术

and try to think fundamentally,

并尝试从根本上思考，

why is it so difficult to make robots walk with two feet?

为什么让机器人用两条腿走路这么难？

And I found something fascinating.

我发现了很有趣的事，

So check this out.

看一下这个。

Now, when your robot tries to move forward,

当你的机器人试往前走，

one of the reasons why it constantly falls down

它总是摔倒的一个理由就是

is because the distance between your left and right leg.

因为你的左腿和右腿之间的空间。

Because your legs move forward and backward, up and down,

因为你的腿前后移动，上下移动，

it creates this unwanted twisting forces,

所以产生了不必要的扭转力，

we call these moments, right?

我们把它们叫做动作，对吗？

Now, this is a video called a RoboOne Competition.

这个视频叫RoboOne比赛。

It's a robot fighting competition.

是一场机器人格斗比赛。

And people who participate in this competition are robot hobbyists.

参加这场比赛的人 是一些机器人爱好者。

And if you look at the robots, they develop, it’s brilliant.

如果你你看见他们开放 的机器人，真的太棒了。

It's fast, it's nimble, and it doesn't fall down.

动作又快又敏捷及不摔掉。

And if you look carefully,

如果你仔细地看

they always walk sideways,

它们总是侧身走，

Because if you walk sideways,

因为如果你侧身走

your left and right leg line up, so your twisting moments disappear.

你的左腿和右腿在一条直线上， 所以你的扭动瞬间消失了。

I actually got this inspiration by watching sports,

其实看运动给我这个灵感

fencing or ballet.

击剑或芭蕾舞。

They always walk sideways, and I think this is the reason why.

他们总是侧身走，而我觉得 是因为这个原因。

Now, one of the problems of trying to make robots move sideways

那，让机器人侧身走的其中一个问题

is you cannot really use your knees.

是你不能用你的膝盖，

So what do we do?

那怎么办？

We rotate our legs.

转动我们的腿。

It looks kind of awkward, right?

看起来奇怪，对吗？

So actually, let's change the entire torso like this

所以，我把躯干这样改变

and make it walk this way.

并让它这样走。

Now, the problem of this kind of configuration

现在，这个配置的问题

is that you really cannot use your feet and ankles.

是你不能用你的脚和脚踝。

So what do we do?

那我们怎么做？

We get rid of them.

把他们扔掉。

Now let's make more changes, let's change the shin.

现在，我们做更多的改变， 让我们换小腿。

And while doing that, let's change the head.

同时也要换头。

And something strange starts to emerge.

一个奇怪的事情就出现

This is NABi, Non Anthropomorphic Biped.

这个是NABi， 非拟人化双足机器人。

In other words, it's a robot with two legs,

换说法，是两腿机器人。

but it does not look like a human.

但是外貌不想人类。

How does it walk?

它怎么走？

It walks like this.

它这样走

Simple, fast, easy, low cost.

简单、快速、容易、低成本。

This is great.

真棒。

Now, I briefly mentioned about a robot called SAFFiR,

我简单提到一个叫 SAFFiR的机器人，

Shipboard Autonomous Fire Fighting Robot that we built.

我们建造的船载自主消防机器人。

This is a robot for Navy ships.

这是海军舰艇机器人。

And I don't know if you've been on a Navy ship, but if you open this door,

不知道你有没有上过海军舰艇， 但是如果你开这个门，

it has a really high door seal.

它有很高的门封条。

We call that “knee-knockers.”

我们把它叫做“护膝”

Before we had this robot, it was very difficult for the robot to climb over it.

有了这个机器人之前， 机器人难以爬过去它。

But if a robot does not have to be like a human,

但是，如果机器人没必要想人一样，

we can do something like this.

我们可以这样做。

Make the knee rotate at 360 degrees.

使膝盖旋转360度。

Brilliant!

太棒了！

Isn't this cool?

这不酷吗？

(Laughs)

（笑声）

Yeah.

对

Our robots can climb stairs, but it's rather difficult.

我们的机器人能爬楼梯， 就是有点儿难。

But now we can climb stairs like this.

不过，现在可以这样爬楼梯。

Now, is this just simulation and animation? No.

那，这只是模拟和动画吗？不是。

In two weeks, from the idea, analysis, design and fabrication,

在两个星期里，从注意、 分析、设计和制造，

in two weeks, we built our first robot.

在两个星期里， 我们建造了第一个机器人。

And you have not seen anything like this.

你没看见这样的事情。

(Video) Man: You're wild.

（视频）男：你疯狂了。

And we use many different types of tricks.

我们使用不同的技巧

For example, utilize the springiness of the feet

比如：使用脚的弹性

we can store the energy and make it hop and jump.

能储存能量并让它跳。

When we first introduced NABi to the community,

当我们第一次向社会介绍NABi 时，

it had a pretty good impact on the community.

它收到了社会的欢迎。

However, this robot is great for walking forward and backward.

不过，这个机器人非常适合前后走

But how does it change directions?

但它怎改变方向？

It can't.

它不能

So we decided to work on the next version called ALPHRED.

所以，我们决定开发下一个型号， 它叫ALPHRED。

ALPHRED stands for Autonomous Leg Personal Helper Robot

ALPHRED代表的 是自主腿私人助手机器人

with Enhanced Dynamics.

具有增强的动力。

So think of this robot as two NABis stacked onto each other.

所以把这个机器人想象成两个 堆叠在一起的两个的NABi。

So it looks like this.

它看起来这样子。

So this robot is axisymmetric,

所以，这个机器人是轴对称的，

which means that there's no forwards, backwards or sideways.

这说明没有向前、向后或侧身。

Now, when it walks, it has a very wide stance, right?

那，走的时候它应该有 很广泛的站姿对吗？

So it can walk like this.

所以，它能这样走。

And this is great for unstructured outdoor environments.

这非常适合非结构化的户外环境。

However, it's pretty slow.

不过，它很慢。

If you want to make it go really fast, you can change your body configuration.

如果想它走得快， 你可以改变身配置

And if you go like this,

如果它是这样，

you can have your forward legs and backward legs,

就有前腿和后腿，

and then you can gallop like a horse.

然后可以疾驰如马。

There you go. (Laughs)

它走了。（笑声）

And when you lift two of the arms it can walk like NABi,

当你抬起两只手臂， 它可以像NABi一样走，

then the two of the other legs can be used as arms

这样另外两条腿可以用作手臂

to pick up boxes or press buttons.

捡起箱子或者按下按钮。

And we're pretty excited about this new type of configuration.

而我们对新的配置感到兴奋

We call this multimodal locomotion, and this is ALPHRED.

我把它叫做多模式移动， 而这是ALPHRED。

Now, while developing these robots,

开发这些机器人时，

we've been also working on this new type of actuator.

我们也一直在研究 这种新型的执行器。

Now, when we say actuators, we're talking about these devices

当我们说执行器， 我的意思是这些让机器人

that make the robots move just like muscles in humans.

行走的器件，就像人的筋肉。

Now, most of the robots that exist today,

今天存在的大多数机器人是，

electric robots, use electric motors with gears, right?

电动机器人，使用带齿轮 的电动机，对吗？

And these are really strong,

这些非常强，

and they're precise, they're good for manufacturing.

准确的并适合生产。

But for legs, we need something different.

但是腿需要不同的事情。

We need something like biological muscles that's compliant, springy,

我们需要像人筋肉一样柔顺和弹性，

and not only the position, but also change the force.

不仅是位置，而且改变力量。

And we developed a new type of actuator called the BEAR actuator.

我们开发了新型执行器， 它叫BEAR执行器。

Now, using this BEAR actuator with the NABi,

将此BEAR执行器 与NABi一起使用，

we developed a second version called NABi-2.

我们开发了第二个型号， 它叫NABi-2.

Now, if you remember, NABi was our experiment

如果你还记得的话， NABi是我们研究

for studying a new type of bipedal locomotion.

新型双足移动试验。

But it turns out that this NABi with these new actuators

但发现使用此新执行器的NABi

doesn't work very well in terms of walking.

在行走方面效果不佳。

However, unexpectedly, we didn't know this,

不过，我们竟然不知道这件事。

but this robot is great for jumping and hopping.

但是这个机器人适合跳跃。

It can jump forward, backward and turn directions, it's brilliant.

它可以向前跳、 向后条和转向，太棒了。

But the really cool thing is, once it jumps and when it lands,

但是最酷的事情是一旦它跳跃和落地

the motors become generators, and the impact is changed to electricity.

它的电动机变成为发电机， 而冲击力变成为电力。

And it can charge its battery, so it’s very energy efficient.

可以充电池，非常节能。

And NABi-2 is ready to go.

NABi-2现在好了。

Or not. (Laughs)

或者还没有。（笑声）

But this is NABi-2.

这就是NABi-2.

So BEAR actuator with NABi was NABi-2,

所以BEAR执行器 跟NABi是NABI-2，

then BEAR actuator with ALPHRED is --

那BEAR执行器跟ALPHRED是...

ALPHRED-2.

ALPHRED-2.

And this is the next generation of ALPHRED.

这是下一代ALPHRED。

So this is the very first time we turned on the switch.

这是我们第一次打开开关

Look carefully at the reaction of our students.

仔细看我们学生的反应。

(Video) Man: Whoa! Oh, my God!

（视频）男：哇！天啊！

What the -- ?

什么--？

Dennis Hong: Excuse me. (Laughs)

Dennis Hong： 不好意思（笑声）

(Video) (Man shouts excitedly)

（视频）（男人兴奋地叫）

Oh, my!

天啊！

Man 2: That was amazing!

男2：太精彩了！

I think it jumped about 1.4 meters.

我觉得它跳了一米四。

This is remarkable.

很了不起了。

Walking is also very fast and stable.

走路也很快很稳。

So we wanted to do something more interesting.

我们想做更有意思的事情。

We wanted to make it do taekwondo.

我们想让它做跆拳道。

(Video) (Men shouting excitedly) Whoa!

（视频）（男人兴奋地叫）哇！

DH: We're just having too much fun.

Dennis Hong： 我们只是玩得很开心。

And ALPHRED-2 is ready to go.

而ALPHRED-2现在好了。

Now, ALPHRED-2 is actually a very practical robot.

ALPHRED-2是一个 非常实用的机器人。

For example, this is an example of picking up a box,

比如，这是它捡起盒子的一个例子，

delivering it and putting it nicely on the ground or on the table.

送它并很好地放在地上或者桌子上。

I sped up the video because it was pretty slow,

我已经加速了视频，因为太慢了，

but you can get an idea how we can use these new type of robots

但是你可以看到我们如何在 不同的用途中使用

for different applications.

这些新型机器人。

And this is ALPHRED-2.

而这是ALPHRED-2.

Now, we looked at two legs.

现在，我们看到了两足。

We looked at four legs.

看到了四足。

What about six legs?

六足呢？

Of course, we have a hexapod robot.

当然，我们有六足机器人。

Now, this robot, HEX, is about the size of a small car.

这个机器人——HEX， 大约有一辆小汽车大小。

Now, the cool thing about six-legged robots is this.

六足机器人最酷的事情就是这个。

Now, to have static stability,

要具有静力稳定性，

the minimum number of contacts with the ground is three.

那接触地面的腿数最少是三条。

Think of a camera tripod.

想一想相机的三脚架。

If you have a hexapod robot,

如果有六足机器人，

you can always have three-point contact with the ground.

你就有三条腿一直接触地面。

Three, three, three.

三条，三条，三条。

And this makes it really great for outdoor environment,

它非常适合户外环境，

rough environment.

粗糙的环境。

This particular robot we're developing for demining applications,

这个机器人我们为 排雷工作而开发的，

getting rid of landmines underground autonomously.

If you see it in person, it’s kind of scary,

如果你亲眼看它了，就有点儿可怕，

it's big and goes like this.

它很大并这样走。

(Laughs)

（笑声）

So this is HEX.

所以这是HEX。

We also have a smaller version,

我们也有更小的，

this is called SiLVIA: Six Legged Vehicle with Intelligent Articulation.

它叫SiLVIA： 智能发音的六足车。

And as I mentioned, these type of robots are really great

我刚才说，这类的机器人非常适合

for unstructured terrain such as this.

这样的非结构化地形。

It can also climb up and down stairs.

它也可以爬上下楼梯，

And this robot might be the strongest six-legged robot out there.

这个机器人有可能 是最强六足机器人。

(Video) Man: Ah, 20 kilograms.

（视频）男：20个公斤。

DH: Now, the reason why we wanted to make it really strong

Dennis Hong：我们想让 它变强的原因是

is because we want this robot to do some very interesting new type of stuff.

想让这机器人做非常有趣的新事情。

So this is the very first robot that can brace between walls and climb up.

所以这是第一个可以支撑在 墙壁之间并爬上的机器人。

So it's like Spiderman, isn't that cool?

像蜘蛛侠一样，不是很酷吗？

And it has some other tricks, too.

它还有其他技巧。

If you put suction cups on the feet, it can stick to the wall and climb.

如果你把吸盘放在脚上， 它就可以粘在墙上爬上去。

And if you give it an arm,

如果给了它一只手臂，

it can do some fun stuff on the blackboard, too.

它也可以在黑板上做有趣的事情。

And this is SiLVIA.

而这是SiLVIA。

So we talked about vertical mobility.

我们谈到垂直流动性。

Twelve years ago, in my last TEDx Talk, I introduced a robot called CLIMBeR.

十二年前，在我上一次TEDx演讲

我介绍了一个机器人叫CLIMBeR

It's a robot for climbing cliffs using cables like a human.

它是一个像人一样 用电缆攀登悬崖的机器人。

But this year, we wanted to get rid of the cable.

但这年，我们想去掉电缆。

We wanted to make it do free climbing.

我们想让它自由攀登。

And I'm very excited to introduce a brand new robot called SCALER,

我很高兴给你们介绍新型的机器人， 它叫ScalER，

Spine Enhanced Climbing Autonomous Legged Exploration Robot.

It's actually very strong, but strength is not all.

它很强，但实力不是全部。

We had to develop this new type of gripper,

我们不得不开发这种新型的抓手，

we call these spine grippers,

我们叫它脊柱抓手，

that can really grab onto the surfaces.

可以抓住表面。

And this video,

而这个视频，

we just took it a few days ago.

我们前几天拍到了。

So literally, it's taking its very first few steps.

所以，它正在迈出最初的几步。

Now, why are we interested in cliff-climbing robots?

那，我们为什么对攀岩机器人感兴趣？

Rescue missions, of course.

肯定是救援任务。

But we're really interested in the planetary applications.

但是我们真是对行星应用感兴趣。

Now, as you know, on Mars,

你们知道，在火星上，

we had these Rovers discovering the new planet.

我们有探索新行星的流动者。

However, the really science-rich sites are always at the cliffs,

不过，具有科学丰富 的地方总是在悬崖，

and these Rovers cannot get there.

而这些流动者无法到达那里。

So something like this will enable those kind of exploration,

所以这样的东西适合这样的探索，

in the science-rich sites on planetary surfaces.

在行星表面上的科学丰富的地方。

This is SCALER.

这个是SCALER。

Now, we talked about legs, but what about wheels?

我们说到腿，轮子呢？

Of course, we have robots with wheels.

肯定有带轮子的机器人。

This is called OmBURo,

And as the name implies, it has one wheel,

顾名思义，它有一个轮子，

it's omnidirectional,

是全向的，

it can go forward, backwards, sideways and diagonal.

它可以前进、后退、侧向和对角线。

But if we look at it, it doesn’t even need to change its orientation.

但是如果看它， 就意识到它不用换方向。

When you see it, it's almost like magic.

看到它的时候，会觉得是魔法。

It feels like it's gliding over the surface.

就像是滑过表面。

Isn't that cool?

Now it follows path, now, yes, it has one wheel,

它遵循路径，对它有一个轮子，

but actually has these smaller rollers in the rim

但其实在轮缘还有更小的滚筒

to generate this kind of motion as well.

这样还可以产生这类的运动。

So why do we want to build a robot like this?

那，我们为什么想要建造这样的机器 人？

We like to have robots living with us in this environment,

我们喜欢有机器人， 可以跟我们生活在这个环境，

and this environment sometimes is crowded, a lot of people or obstacles.

而这个环境有时候很拥挤， 有很多人或障碍。

To go through people or to avoid obstacles,

为了穿过人或者避开障碍物，

it's very important to have a very small cross section,

它很重要有很小的交叉区域，

and probably a single wheel is the best way to have a very small cross section.
