I know this is going to sound声音 strange奇怪,
0
577
2475
我知道这听起来很奇怪,
00:18
but I think robots机器人 can inspire启发 us
1
3052
3294
但我认为机器人可以启发我们
00:22
to be better humans人类.
2
6346
2388
去做更好的人。
00:24
See, I grew成长 up in Bethlehem伯利恒, Pennsylvania宾夕法尼亚,
3
8734
3629
我在宾夕法尼亚州的伯利恒长大,
00:28
the home of Bethlehem伯利恒 Steel.
4
12363
2321
那里是伯利恒钢铁之乡。
00:30
My father父亲 was an engineer工程师,
5
14684
2079
我的父亲是一名工程师,
00:32
and when I was growing生长 up, he would teach me
6
16763
2851
当我一天天长大,他教给我
00:35
how things worked工作.
7
19614
1159
事物是如何运行的。
00:36
We would build建立 projects项目 together一起,
8
20773
2815
我们在一起做项目
00:39
like model模型 rockets火箭 and slot插槽 cars汽车.
9
23588
2792
比如火箭模型和插槽汽车。
00:42
Here's这里的 the go-kart卡丁车 that we built内置 together一起.
10
26380
3284
这里是我们一起做的卡丁车。
00:45
That's me behind背后 the wheel,
11
29664
2219
方向盘后面这个是我
00:47
with my sister妹妹 and my best最好 friend朋友 at the time,
12
31883
3819
还有我的妹妹和我当时最好的朋友,
00:51
and one day,
13
35702
2123
一天,
00:53
he came来了 home, when I was about 10 years年份 old,
14
37825
3107
他回家,那时我10 岁左右
00:56
and at the dinner晚餐 table, he announced公布
15
40932
2304
在饭桌上,他宣布
00:59
that for our next下一个 project项目, we were going to build建立 a robot机器人.
16
43236
6438
下一个项目,我们打算做一个机器人。
01:05
A robot机器人.
17
49674
1109
一个机器人。
01:06
Now, I was thrilled高兴 about this,
18
50783
2252
当时,我超级激动
01:08
because at school学校,
19
53035
1590
因为在学校,
01:10
there was a bully欺负 named命名 Kevin凯文,
20
54625
2075
有名叫凯文的小霸王
01:12
and he was picking选择 on me
21
56700
2246
老是欺负我
01:14
because I was the only Jewish犹太 kid孩子 in class.
22
58946
2414
因为我是班里唯一的犹太孩子。
01:17
So I couldn't不能 wait to get started开始 to work on this
23
61360
2813
所以我迫不及待要开始着手做
01:20
so I could introduce介绍 Kevin凯文 to my robot机器人. (Laughter笑声)
24
64173
3822
这样我就可以让凯文认识认识我的机器人。(笑声)
01:23
(Robot机器人 noises噪音)
25
67995
11063
(机器人噪音)
01:34
But that wasn't the kind of robot机器人 my dad had in mind心神.
26
79058
4875
但这并不是的我爸爸想的那种机器人。
01:39
See, he owned拥有的 a chromium plating电镀 company公司,
27
83933
3728
你看,他拥有一家镀铬公司
01:43
and they had to move移动
28
87661
2176
他们不得不得在
01:45
heavy steel parts部分 between之间 tanks坦克 of chemicals化学制品,
29
89837
3096
大量的化学品中搬运重钢部件
01:48
and so he needed需要 an industrial产业 robot机器人 like this
30
92933
3790
所以他需要像这样的工业机器人
01:52
that could basically基本上 do the heavy lifting吊装.
31
96723
3099
基本上要能做托举的事。
01:55
But my dad didn't get the kind of robot机器人 he wanted, either.
32
99822
3905
但我爸没得到他想要的那种机器人,
01:59
He and I worked工作 on it for several一些 years年份,
33
103727
2597
我和他研究了几年,
02:02
but it was the 1970s,
34
106324
1978
但当时是 1970 年代,
02:04
and the technology技术 that was available可得到 to amateurs业余
35
108302
2526
暂时还没有
02:06
just wasn't there yet然而.
36
110828
2657
提供给业余人士的技术
02:09
So Dad continued继续 to do this kind of work by hand,
37
113485
3745
所以爸爸继续手工做这种工作
02:13
and a few少数 years年份 later后来,
38
117230
2275
几年以后,
02:15
he was diagnosed确诊 with cancer癌症.
39
119505
4139
他被诊断出患上癌症
02:19
You see, what the robot机器人 we were trying to build建立
40
123644
3305
你看,我们在试着做的机器人
02:22
was telling告诉 him was not about doing the heavy lifting吊装.
41
126949
3267
正告诉他别做重型起重。
02:26
It was a warning警告 about his exposure曝光 to the toxic有毒的 chemicals化学制品.
42
130216
4308
这是向他发出别接触有毒化学品的警告。
02:30
He didn't recognize认识 that at the time,
43
134524
2977
他那时并没有意识到,
02:33
and he contracted签约 leukemia白血病,
44
137501
2139
他还染上了白血病,
02:35
and he died死亡 at the age年龄 of 45.
45
139640
3222
45 岁的时候去世了
02:38
I was devastated满目疮痍 by this,
46
142862
2841
我被击溃了,
02:41
and I never forgot忘记 the robot机器人 that he and I tried试着 to build建立.
47
145703
4575
然而我永远不会忘了我们尝试做的机器人。
02:46
When I was in college学院, I decided决定 to study研究 engineering工程, like him.
48
150278
4311
我在大学的时候,决定修读工程学,就像他一样。
02:50
And I went to Carnegie卡内基 Mellon梅隆, and I earned my PhD博士 in robotics机器人.
49
154589
4946
我去了卡耐基梅隆大学,取得了我的机器人技术博士学位。
02:55
I've been studying研究 robots机器人 ever since以来.
50
159535
3094
从那时起我一直研究机器人。
02:58
So what I'd like to tell you about
51
162629
1638
所以我想告诉你们的是
03:00
are four robot机器人 projects项目
52
164267
2714
四 个机器人项目
03:02
and how they've他们已经 inspired启发 me to be a better human人的.
53
166981
7044
还有他们如何鼓舞我成为一个更好的人。
03:09
By 1993, I was a young年轻 professor教授 at USCUSC,
54
174025
5749
1993 年,我是南加州大学的年轻教授
03:15
and I was just building建造 up my own拥有 robotics机器人 lab实验室,
55
179774
3037
我刚建好我自己的机器人技术实验室,
03:18
and this was the year that the World世界 Wide Web卷筒纸 came来了 out.
56
182811
3585
这也是互联网出来的那一年,
03:22
And I remember记得 my students学生们 were the ones那些
57
186396
1176
我记得我的学生就是那些
03:23
who told me about it,
58
187572
1704
那些告诉我互联网的人
03:25
and we would -- we were just amazed吃惊.
59
189276
2619
我们当时都十分惊叹。
03:27
We started开始 playing播放 with this, and that afternoon下午,
60
191895
3434
我们开始摆弄,那天下午,
03:31
we realized实现 that we could use this new, universal普遍 interface接口
61
195329
3853
我们意识到我们可以利用这个新的、 通用的接口
03:35
to allow允许 anyone任何人 in the world世界
62
199182
2543
使得世界上任何人
03:37
to operate操作 the robot机器人 in our lab实验室.
63
201725
3048
都能操作在我们实验室的机器人。
03:40
So, rather than have it fight斗争 or do industrial产业 work,
64
204773
5708
于是,我们打算造播种机
03:46
we decided决定 to build建立 a planter播种机,
65
210481
2486
而不是用机器人来打架或是投入工业
03:48
put the robot机器人 into the center中央 of it,
66
212967
1976
把它放进播种机中间,
03:50
and we called it the TelegardenTelegarden.
67
214943
2353
我们管它叫Telegrarden。
03:53
And we had put a camera相机 in the gripper夹具 of the hand
68
217296
3603
我们还放了一台相机在机器人把手的
03:56
of the robot机器人, and we wrote some special特别 scripts脚本
69
220899
2709
抓手上,我们写了一些特殊的脚本
03:59
and software软件 so that anyone任何人 in the world世界 could come in
70
223608
3161
和软件,如此一来,世界上任何人都能进来
04:02
and by clicking点击 on the screen屏幕
71
226769
2329
并通过在屏幕上单击
04:04
they could move移动 the robot机器人 around
72
229098
2173
就可以移动机器人
04:07
and visit访问 the garden花园.
73
231271
2316
还能参观花园。
04:09
But we also allowed允许, set up some other software软件
74
233587
3620
而且,我们同时还设置一些其他软件
04:13
that lets让我们 you participate参加 and help us water the garden花园
75
237207
3419
允许你们参与和帮助我们在花园远程浇水
04:16
remotely远程, and if you water it a few少数 times,
76
240626
3045
如果你多浇它几次,
04:19
we'd星期三 give you your own拥有 seed种子 to plant.
77
243671
3585
我们就会给你些种子,自己来种。
04:23
Now, this was a project项目, an engineering工程 project项目,
78
247256
3271
这是一个项目,工程项目
04:26
and we published发表 some papers文件 on the design设计,
79
250527
2776
我们发表了一些论文,关于它的设计,
04:29
the system系统 design设计 of it, but we also thought of it
80
253303
2249
系统的设计,但我们也把它看做
04:31
as an art艺术 installation安装.
81
255552
3086
是一种艺术装置。
04:34
It was invited邀请, after the first year,
82
258638
2173
一年后,它被请到
04:36
by the ArsARS Electronica电子乐 Museum博物馆 in Austria奥地利
83
260811
3044
奥地利的 Ars 电子乐博物馆里去
04:39
to have it installed安装 in their lobby前厅,
84
263855
3000
装在他们的大厅里,
04:42
and I'm happy快乐 to say it remained保持 online线上 there,
85
266855
2418
我很高兴地说,将近九年
04:45
24 hours小时 a day, for almost几乎 nine years年份.
86
269273
4983
一天二十四小时,它依然在线运行。
04:50
That robot机器人 was operated操作 by more people
87
274256
3799
操纵这个机器人的人
04:53
than any other robot机器人 in history历史.
88
278055
3086
比史上任何一个机器人都多
04:57
Now, one day,
89
281141
1554
有一天,
04:58
I got a call out of the blue蓝色
90
282695
2317
我突然接到一个意外的电话
05:00
from a student学生,
91
285012
2015
一个学生打来的
05:02
who asked a very simple简单 but profound深刻 question.
92
287027
4670
问了一个非常简单但又深刻的问题。
05:07
He said, "Is the robot机器人 real真实?"
93
291697
4538
他说,“机器人是真的吗?”
05:12
Now, everyone大家 else其他 had assumed假定 it was,
94
296235
2765
所有人都觉得它是,
05:14
and we knew知道 it was because we were working加工 with it.
95
299000
2331
而我们知道,因为我们和它一同工作。
05:17
But I knew知道 what he meant意味着,
96
301331
1540
但我知道他的意思,
05:18
because it would be possible可能 to take a bunch of pictures图片
97
302871
2593
因为它将有可能拍一组花园里
05:21
of flowers花卉 in a garden花园 and then, basically基本上, index指数 them
98
305464
4361
花朵的图片,然后,基本上,把索引加到
05:25
in a computer电脑 system系统 such这样 that it would appear出现
99
309825
2229
在计算机系统里,这样就看起来
05:27
that there was a real真实 robot机器人 when there wasn't.
100
312054
3074
像是真有这么一个机器人,而实际上没有。
05:31
And the more I thought about it, I couldn't不能 think
101
315128
1241
我越是想到这个问题,我越是想不出
05:32
of a good answer回答 for how he could tell the difference区别.
102
316369
3551
一个好答案,来告诉他个中区别
05:35
This was right about the time that I was offered提供 a position位置
103
319920
2887
那时有个恰巧的时机,我被提供一个职位,
05:38
here at Berkeley伯克利,
104
322807
2073
在这里,加州大学柏克莱分校,
05:40
and when I got here, I looked看着 up Hubert休伯特 Dreyfus德雷福斯,
105
324880
3552
我来这里,我咨询了休伯特 · 福斯,
05:44
who's谁是 a world-renowned世界知名 professor教授 of philosophy哲学,
106
328432
3665
世界知名的哲学教授,
05:47
and I talked with him about this, and he said,
107
332097
2374
我和他谈到这一点,他说:
05:50
"This is one of the oldest最老的 and most central中央 problems问题
108
334471
3560
"这是哲学里最古老和最核心的问题之一
05:53
in philosophy哲学. It goes back to the Skeptics怀疑论者,
109
338031
3602
这要追溯到怀疑论者,
05:57
and up through通过 Descartes笛卡尔.
110
341633
1960
直到笛卡尔。
05:59
It's the issue问题 of epistemology认识论,
111
343593
3170
这是认识论的问题,
06:02
the study研究 of how do we know that something is true真正."
112
346763
3750
是研究我们怎么知道什么是真的."
06:06
So he and I started开始 working加工 together一起,
113
350513
2223
所以我和他开始一起工作,
06:08
and we coined创造 a new term术语: telepistemologytelepistemology,
114
352736
3041
我们创造了一个新名词: telepistemology,
06:11
the study研究 of knowledge知识 at a distance距离.
115
355777
3526
对知识的远程研究。
06:15
We invited邀请 leading领导 artists艺术家, engineers工程师,
116
359303
2752
我们邀请了著名艺术家、 工程师、
06:17
and philosophers哲学家 to write essays随笔 about this,
117
362055
3064
还有哲学家,就此写论文
06:21
and the results结果, the results结果 are collected in this book
118
365119
2340
这些结果收录在麻省理工学院出版社出版的
06:23
from MITMIT Press.
119
367459
2621
这本书里。
06:25
So thanks谢谢 to this student学生 who questioned质疑
120
370080
2332
谢谢这位对人人都信以为真的东西,
06:28
what everyone大家 else其他 had assumed假定 to be true真正,
121
372412
2803
提出质疑的学生
06:31
this project项目 taught me an important重要 lesson about life,
122
375215
4208
这个项目教给我人生重要的一课,
06:35
which哪一个 is to always question assumptions假设.
123
379423
4073
那就是总是质疑假设。
06:39
Now, the second第二 project项目 I'll tell you about
124
383496
2648
现在,我要告诉你们第二个项目
06:42
grew成长 out of the TelegardenTelegarden.
125
386144
1879
是由Telegarden 培养起来的。
06:43
As it was operating操作, my students学生们 and I were very interested有兴趣
126
388023
2576
在它运行期间,我和我的学生都很感兴趣
06:46
in how people were interacting互动 with each other
127
390599
2762
人们直接如何彼此互动
06:49
and what they were doing with the garden花园.
128
393361
1621
他们在花园里做什么。
06:50
So we started开始 thinking思维, what if the robot机器人 could leave离开
129
394982
2262
所以我们开始思考,如果机器人能离开
06:53
the garden花园 and go out into some other
130
397244
2083
花园,出到其他一些
06:55
interesting有趣 environment环境?
131
399327
1992
有趣的环境
06:57
Like, for example, what if it could go to a dinner晚餐 party派对
132
401319
2179
比如,如果它走到白宫
06:59
at the White白色 House? (Laughter笑声)
133
403498
5198
去参加一个晚宴?(笑声)
07:04
So, because we were interested有兴趣 more in the system系统 design设计
134
408696
2841
于是,因为我们更感兴趣的是系统设计
07:07
and the user用户 interface接口 than in the hardware硬件,
135
411537
3286
以及用户界面而非硬件
07:10
we decided决定 that, rather than have
136
414823
2034
我们决定,并非是要
07:12
a robot机器人 replace更换 the human人的 to go to the party派对,
137
416857
3678
机器人代替人去参加聚会,
07:16
we'd星期三 have a human人的 replace更换 the robot机器人.
138
420535
2843
我们会有人代替机器人去。
07:19
We called it the Tele-Actor远程演员.
139
423378
2600
我们叫它远程演员。
07:21
We got a human人的,
140
425978
2032
我们有这么一个人,
07:23
someone有人 who's谁是 very outgoing传出 and gregarious群居,
141
428010
3007
一个非常外向和合群的人,
07:26
and she was outfitted装备 with a helmet头盔
142
431017
3142
给她配了头盔
07:30
with various各个 equipment设备, cameras相机 and microphones麦克风,
143
434159
2570
还有各种设备、 摄像头和麦克风,
07:32
and then a backpack背包 with wireless无线 Internet互联网 connection连接,
144
436729
3740
还有一个带无线网络连接的背包
07:36
and the idea理念 was that she could go into a remote远程 and
145
440469
3359
我们的想法是,她进到一个远程的
07:39
interesting有趣 environment环境, and then over the Internet互联网,
146
443828
3815
有趣的环境中,然后通过互联网,
07:43
people could experience经验 what she was experiencing经历,
147
447643
3151
人们可以经历她所经历的
07:46
so they could see what she was seeing眼看,
148
450794
2937
他们可以看到她所看到的,
07:49
but then, more importantly重要的, they could participate参加
149
453731
3307
然后,更重要的是,他们能够通过彼此的互动
07:52
by interacting互动 with each other
150
457038
2948
来参与其中
07:55
and coming未来 up with ideas思路 about what she should do next下一个
151
459986
3705
并且想出她下一步该做什么
07:59
and where she should go,
152
463691
2216
她该去哪里
08:01
and then conveying输送 those to the Tele-Actor远程演员.
153
465907
3162
然后把这些想法传输给远程演员。
08:04
So we got a chance机会 to take the Tele-Actor远程演员
154
469069
2445
于是我们得到一个机会让远程演员
08:07
to the Webby威比 Awards奖项 in San Francisco弗朗西斯科,
155
471514
3615
去旧金山的威比奖现场
08:11
and that year, Sam山姆 Donaldson唐纳森 was the host主办.
156
475129
4111
那一年,主持人是山姆 · 唐纳森。
08:15
Just before the curtain窗帘 went up, I had about 30 seconds
157
479240
3642
在大幕升起之前,我只有大约 30 秒
08:18
to explain说明 to Mr先生. Donaldson唐纳森 what we were gonna do,
158
482882
4458
向唐纳森先生解释,我们打算干嘛
08:23
and I said, "The Tele-Actor远程演员
159
487340
1864
我说:“远程演员
08:25
is going to be joining加盟 you on stage阶段,
160
489204
2456
将会加入你,和你一同站在台上,
08:27
and this is a new experimental试验 project项目,
161
491660
2198
这是一个新的实验项目,
08:29
and people are watching观看 her on their screens屏幕,
162
493858
2625
人们在他们的屏幕上看着她
08:32
and she's got -- there's cameras相机 involved参与 and there's
163
496483
2305
她有相机
08:34
microphones麦克风 and she's got an earbud耳塞 in her ear,
164
498788
2911
有麦克风,在她的耳边,还有耳塞
08:37
and people over the network网络 are giving her advice忠告
165
501699
1447
网络上的人会给她建议
08:39
about what to do next下一个."
166
503146
1368
告诉她接下来做什么"。
08:40
And he said, "Wait a second第二,
167
504514
3209
他说,"等一下,
08:43
that's what I do." (Laughter笑声)
168
507723
6375
这不是我干的事吗”(笑声)
08:49
So he loved喜爱 the concept概念,
169
514098
1931
他爱这个理念,
08:51
and when the Tele-Actor远程演员 walked onstage在舞台上,
170
516029
2340
当远程演员走上舞台的时候,
08:54
she walked right up to him, and she gave him a big kiss
171
518369
2821
她径直走向他,给了他一个大大的吻
08:57
right on the lips嘴唇. (Laughter笑声)
172
521190
3106
正好吻在嘴唇上。(笑声)
09:00
We were totally完全 surprised诧异.
173
524296
1131
我们完全惊到了。
09:01
We had no idea理念 that would happen发生.
174
525427
2017
我们根本不知道会发生这个。
09:03
And he was great. He just gave her a big hug拥抱 in return返回,
175
527444
2692
他很棒。他就回以她一个热烈的拥抱,
09:06
and it worked工作 out great.
176
530136
1769
效果很好
09:07
But that night, as we were packing填料 up,
177
531905
2064
但那天晚上,当我们在打包的时候,
09:09
I asked the Tele-Actor远程演员, how did the Tele-Directors远程董事
178
533969
3608
我问那个远程演员,远程导演们怎么会
09:13
decide决定 that they would give a kiss to Sam山姆 Donaldson唐纳森?
179
537577
5558
决定他们要向 山姆·唐纳森献吻?
09:19
And she said they hadn't有没有.
180
543135
2212
她说:他们没有
09:21
She said, when she was just about to walk步行 on stage阶段,
181
545347
2434
她说,当她刚要走上台时,
09:23
the Tele-Directors远程董事 were still trying to agree同意 on what to do,
182
547781
2312
远程导演们仍在试图达成一致到底要做什么,
09:25
and so she just walked on stage阶段 and did
183
550093
2407
因此她刚刚走上舞台,就做了
09:28
what felt most natural自然. (Laughter笑声)
184
552500
5522
感觉最自然的事。(笑声)
09:33
So, the success成功 of the Tele-Actor远程演员 that night
185
558022
3670
这样,远程演员当夜的成功
09:37
was due应有 to the fact事实 that she was a wonderful精彩 actor演员.
186
561692
4373
归功于她是个很棒的演员。
09:41
She knew知道 when to trust相信 her instincts本能,
187
566065
2357
她知道何时该相信她的本能,
09:44
and so that project项目 taught me another另一个 lesson about life,
188
568422
3864
因此,这个项目教给我,人生的另一课
09:48
which哪一个 is that, when in doubt怀疑, improvise凑合. (Laughter笑声)
189
572286
6379
也就是,纠结时,即兴来。(笑声)
09:54
Now, the third第三 project项目 grew成长 out of
190
578665
3080
第三个项目是基于
09:57
my experience经验 when my father父亲 was in the hospital醫院.
191
581745
4893
我父亲在医院时,我的经验。
10:02
He was undergoing经历 a treatment治疗,
192
586638
2240
他在接受治疗,
10:04
chemotherapy化疗 treatments治疗, and there's a related有关 treatment治疗
193
588878
3633
化疗,还有个相关的疗法
10:08
called brachytherapy近距离放射治疗, where tiny, radioactive放射性的 seeds种子
194
592511
5048
被称为近距离放疗,很小,放射性的籽
10:13
are placed放置 into the body身体 to treat对待 cancerous癌的 tumors肿瘤.
195
597559
4211
被放到身体里,来治疗癌性肿瘤。
10:17
And the way it's doneDONE, as you can see here,
196
601770
2097
做的方法,你可以看到,在这儿
10:19
is that surgeons外科医生 insert needles into the body身体
197
603867
4391
外科医生将针插入身体
10:24
to deliver交付 the seeds种子, and all this,
198
608258
2592
把籽送进去,这所有的一切,
10:26
all these needles are inserted插入 in parallel平行,
199
610850
3433
所有这些针都并排插进去,
10:30
so it's very common共同 that some of the needles
200
614283
2975
所以经常地,有些针
10:33
penetrate穿透 sensitive敏感 organs器官, and as a result结果,
201
617258
4817
会穿透易受伤的器官,结果就是
10:37
the needles damage损伤 these organs器官, cause原因 damage损伤
202
622075
5063
这些针损伤了这些器官, 造成了伤害
10:43
which哪一个 leads引线 to trauma外伤 and side effects效果.
203
627138
3487
造成了创伤和副作用。
10:46
So my students学生们 and I wondered想知道, what if we could
204
630625
2500
所以我和我的学生们想知道,如果我们可以
10:49
modify修改 the system系统
205
633125
3485
改进这个系统
10:52
so that the needles could come in at different不同 angles?
206
636610
3785
那么,针能从不同的角度进去吗?
10:56
So we simulated模拟 this, and we developed发达 some
207
640395
2777
所以我们模拟了这个,开发了一些
10:59
optimization优化 algorithms算法 and we simulated模拟 this,
208
643172
2589
优化算法。我们模拟的这个
11:01
and we were able能够 to show显示 that we are able能够 to avoid避免
209
645761
2277
能够表明我们是可以避开
11:03
the delicate精巧 organs器官 and yet然而 still achieve实现 the coverage覆盖
210
648038
3767
脆弱的器官并且仍然能够实现对
11:07
of the tumors肿瘤 with the radiation辐射.
211
651805
3508
肿瘤范围的辐射。
11:11
So now, we're working加工 with doctors医生 at UCSFUCSF
212
655313
3498
我们正在和加州大学旧金山分校的医生
11:14
and engineers工程师 at Johns约翰斯 Hopkins霍普金斯
213
658811
2696
还有约翰 · 霍普金斯大学的工程师
11:17
and we're building建造 a robot机器人 that has a number of,
214
661507
3582
一起制作一个具有很多的
11:20
it's a specialized专门 design设计 with different不同 joints关节 that can allow允许
215
665089
3257
专门的设计带着不同的接头的机器人,可以使得
11:24
the needles to come in at an infinite无穷 variety品种 of angles,
216
668346
4258
针能从无限多个角度进来,
11:28
and as you can see here, they can avoid避免 delicate精巧 organs器官
217
672604
3166
你还可以在这里看到,它们能避开脆弱的器官
11:31
and still reach达到 the targets目标 they're aiming瞄准 for.
218
675770
4138
且仍然触及它们所瞄准的目标。
11:35
So, by questioning疑问 this assumption假设 that all the needles
219
679908
3317
那么,通过质疑所有针都需要平行这种假设
11:39
have to be parallel平行, this project项目 also taught me
220
683225
2945
这个项目还教给我
11:42
an important重要 lesson: When in doubt怀疑 --
221
686170
3300
重要的一课: 当有疑问的时候 — —
11:45
When your path路径 is blocked受阻, pivot.
222
689470
4367
当前路受阻的时候,换个角度。
11:49
And the last project项目 also has to do with medical robotics机器人.
223
693837
4401
最后一个项目也跟医疗机器人技术有关。
11:54
And this is something that's grown长大的 out of a system系统 called
224
698238
4040
这是从一个叫做达芬奇手术机器人
11:58
the daDA Vinci达芬奇 surgical外科 robot机器人,
225
702278
3588
的系统里产生的,
12:01
and this is a commercially商业 available可得到 device设备.
226
705866
2468
这是一个商业上可用的设备。
12:04
It's being存在 used in over 2,000 hospitals医院 around the world世界,
227
708334
3332
在世界各地,超过 2000 家医院正在使用它
12:07
and the idea理念 is it allows允许 the surgeon外科医生
228
711666
2528
它使外科医生
12:10
to operate操作 comfortably舒服 in his own拥有 coordinate坐标 frame,
229
714194
4249
能在他自己舒服的地盘里手术
12:14
but many许多 of the subtasks子任务 in surgery手术
230
718443
4991
但许多手术中的子任务
12:19
are very routine常规 and tedious乏味, like suturing缝合,
231
723434
3047
是非常例行公事和又乏味的,比如缝合,
12:22
and currently目前, all of these are performed执行
232
726481
2365
然而目前,所有这些都在外科医生特定的
12:24
under the specific具体 and immediate即时 control控制 of the surgeon外科医生,
233
728846
4420
实时的控制之下完成的。
12:29
so the surgeon外科医生 becomes fatigued疲劳 over time.
234
733266
2658
因此,随着时间的推移,外科医生变得倦怠。
12:31
And we've我们已经 been wondering想知道,
235
735924
1295
我们想知道,
12:33
what if we could program程序 the robot机器人
236
737219
2265
我们是否能给机器人编程,
12:35
to perform演出 some of these subtasks子任务,
237
739484
2487
来让它执行这些子任务的一部分
12:37
and thereby从而 free自由 the surgeons外科医生 to focus焦点
238
741971
1720
从而把外科医生解放出来,去关注
12:39
on the more complicated复杂 parts部分 of the surgery手术,
239
743691
2656
手术更复杂的部分
12:42
and also cut down on the time that the surgery手术 would take
240
746347
3248
同时还能省下外科手术所需的时间
12:45
if we could get the robot机器人 to do them a little bit faster更快?
241
749595
3023
如果我们让机器人做得快点的话
12:48
Now, it's hard to program程序 a robot机器人 to do delicate精巧 things
242
752618
2434
给机器人编程做这样精细的事是很难的
12:50
like this, but it turns out my colleague同事, Pieter彼得 AbbeelAbbeel,
243
755052
4079
不过我的同事,来自加州大学伯克利分校的
12:55
who's谁是 here at Berkeley伯克利, has develelopeddeveleloped
244
759131
2416
这儿的Pieter Abbeel,开发了
12:57
a new set of techniques技术 for teaching教学 robots机器人 from example.
245
761547
5623
一套新的技术,用实例来教会机器人
13:03
So he's gotten得到 robots机器人 to fly helicopters直升机,
246
767170
2767
他已经教会机器人驾驶直升机,
13:05
do incredibly令人难以置信 interesting有趣, beautiful美丽 acrobatics杂技,
247
769937
3104
通过看专业人士飞行
13:08
by watching观看 human人的 experts专家 fly them.
248
773041
2719
来做不可思议的、有趣的、美妙的特技。
13:11
So we got one of these robots机器人.
249
775760
2588
我们拿到这些机器人中的一个。
13:14
We started开始 working加工 with Pieter彼得 and his students学生们,
250
778348
2182
我们开始和彼得还有他的学生们一起工作
13:16
and we asked a surgeon外科医生 to perform演出
251
780530
2663
我们请了一位外科医生来操作
13:19
a task任务, and what we do is we, with the robot机器人,
252
783193
4451
一项任务。而我们做的就是和机器人一起
13:23
so what we're doing is asking the robot机器人,
253
787644
2063
我们在做的就是让机器人,
13:25
the surgeon外科医生 to perform演出 the task任务,
254
789707
1278
进行外科医生的任务
13:26
and we record记录 the motions运动 of the robot机器人.
255
790985
2272
然后我们记录机器人的动作。
13:29
So here's这里的 an example. I'll use a figure数字 eight,
256
793257
2128
这是一个例子。我要用数字8
13:31
tracing追踪 out a figure数字 eight as an example.
257
795385
2240
用描出一个数字8作例子
13:33
So here's这里的 what it looks容貌 like when the robot机器人,
258
797625
3630
这是机器人做的样子
13:37
this is what the robot's机器人 path路径 looks容貌 like,
259
801255
2317
这是机器人描出来的样子
13:39
those three examples例子.
260
803572
1174
这有三个例子。
13:40
Now, those are much better than what a novice初学者
261
804746
2462
这些比新手做的好很多
13:43
like I could do, but they're still jerky生涩的 and imprecise不精确.
262
807208
4657
比如我所做的。但他们仍是生涩且不精确。
13:47
So we record记录 all these examples例子, the data数据,
263
811865
2072
所以我们记录所有这些例子,数据,
13:49
and then we go through通过 a sequence序列 of steps脚步.
264
813937
3712
然后我们进行一系列步骤。
13:53
First, we used a technique技术 called dynamic动态 time warping翘曲
265
817649
3632
首先,我们使用一种从语音识别里来的
13:57
from speech言语 recognition承认, and this allows允许 us to
266
821281
2182
叫做动态时间规整的技术。这使我们
13:59
temporally时间 align对齐 all of the examples例子,
267
823463
2840
能暂时匹配的所有示例,
14:02
and then we apply应用 Kalman卡尔曼 filtering滤波,
268
826303
2929
然后我们应用卡尔曼滤波,
14:05
a technique技术 from control控制 theory理论, that allows允许 us
269
829232
2983
一种来自控制论的技术,使我们
14:08
to statistically统计学 analyze分析 all the noise噪声
270
832215
2672
能够统计上分析所有的噪音
14:10
and extract提取 the desired期望 trajectory弹道 that underliesunderlies them.
271
834887
6183
并提取所需的对应轨迹
14:16
Now, so what we're doing is that we take those
272
841070
1994
我们在做的是考虑那些
14:18
human人的 demonstrations示威, they're all noisy嘈杂 and imperfect不完善,
273
843064
2023
人类的操作演示,它们都是嘈杂的、不完美的
14:20
and we extract提取 from them an inferred推断 task任务 trajectory弹道
274
845087
3091
我们提取出一个推断出的任务轨迹
14:24
and control控制 sequence序列 for the robot机器人.
275
848178
3003
以及控制机器人的程序
14:27
We then execute执行 that on the robot机器人,
276
851181
2184
然后我们用机器人来执行,
14:29
we observe what happens发生,
277
853365
2172
我们观察会发生什么情况,
14:31
then we adjust调整 the controls控制 using运用 a sequence序列 of techniques技术
278
855537
2662
然后我们用一系列技术来调整控件
14:34
called iterative迭代 learning学习.
279
858199
2930
这叫做迭代学习。
14:37
Then what we do is, we increase增加 the velocity速度 a little bit.
280
861129
3977
接下来我们做的是,稍微提高速率。
14:41
We observe the results结果, adjust调整 the controls控制 again,
281
865106
3563
根据我们观察到的结果,再次调整控件
14:44
and observe what happens发生.
282
868669
2522
观察会发生什么情况。
14:47
And we go through通过 this several一些 rounds.
283
871191
2136
我们检查好几轮
14:49
And here's这里的 the result结果.
284
873327
1356
这是结果。
14:50
That's the inferred推断 task任务 trajectory弹道,
285
874683
1845
这就是推断出的任务的轨迹,
14:52
and here's这里的 the robot机器人 moving移动 at the speed速度 of the human人的.
286
876528
3463
这是以人类的速度运行的机器人。
14:55
Here's这里的 four times the speed速度 of the human人的.
287
879991
2442
这是人类的速度的四倍。
14:58
Here's这里的 seven times.
288
882433
2571
这里是七倍。
15:00
And here's这里的 the robot机器人 operating操作 at 10 times
289
885004
3637
这是以人速十倍
15:04
the speed速度 of the human人的.
290
888641
2200
运行的机器人
15:06
So we're able能够 to get a robot机器人 to perform演出 a delicate精巧 task任务,
291
890841
2950
所以,我们要想能够让机器人来做精细的任务,
15:09
like a surgical外科 subtask子任务,
292
893791
3224
比如外科的子任务,
15:12
at 10 times the speed速度 of a human人的.
293
897015
3247
就要以人的速度十倍来进行。
15:16
So this project项目 also, because of its involved参与 practicing
294

我从机器人那里学来的四课
15:42
and robotics机器人, the field领域 of robotics机器人 has gotten得到 much better
301
926752
5369
机器人学,机器人技术领域随着时间的过去
15:48
over time.
302
932121
2168
已经进步很多
15:50
Nowadays如今, high school学校 students学生们 can build建立 robots机器人
303
934289
2167
如今,高中学生可以造机器人
15:52
like the industrial产业 robot机器人 my dad and I tried试着 to build建立.
304
936456
4025
像我爸爸和我尝试造的工业机器人
15:56
And now, I have a daughter女儿,
305
940481
