Leila Takayama: What's it like to be a robot?

Filmed:
1,183,118 views

We already live among robots: tools and machines like dishwashers and thermostats so integrated into our lives that we'd never think to call them that. What will a future with even more robots look like? Social scientist Leila Takayama shares some unique challenges of designing for human-robot interactions -- and how experimenting with robotic futures actually leads us to a better understanding of ourselves.

You only get one chance
to make a first impression,
0
760
2656
00:15
and that's true if you're a robot
as well as if you're a person.
1
3440
3176
00:18
The first time that I met
one of these robots
2
6640
3016
00:21
was at a place
called Willow Garage in 2008.
3
9680
2896
00:24
When I went to visit there,
my host walked me into the building
4
12600
3016
00:27
and we met this little guy.
5
15640
1576
00:29
He was rolling into the hallway,
6
17240
1656
00:30
came up to me, sat there,
7
18920
1816
00:32
stared blankly past me,
8
20760
2256
00:35
did nothing for a while,
9
23040
1656
00:36
rapidly spun his head around 180 degrees
10
24720
1936
00:38
and then ran away.
11
26680
1536
00:40
And that was not a great first impression.
12
28240
2176
00:42
The thing that I learned
about robots that day
13
30440
2176
00:44
is that they kind of do their own thing,
14
32640
2176
00:46
and they're not totally aware of us.
15
34840
2136
00:49
And I think as we're experimenting
with these possible robot futures,
16
37000
3239
00:52
we actually end up learning
a lot more about ourselves
17
40263
2673
00:54
as opposed to just these machines.
18
42960
1656
00:56
And what I learned that day
19
44640
1336
00:58
was that I had pretty high
expectations for this little dude.
20
46000
3416
01:01
He was not only supposed to be able
to navigate the physical world,
21
49440
3176
01:04
but also be able
to navigate my social world --
22
52640
2656
01:07
he's in my space; it's a personal robot.
23
55320
2176
01:09
wWhy didn't it understand me?
24
57520
2016
01:11
My host explained to me,
25
59560
1256
01:12
"Well, the robot is trying
to get from point A to point B,
26
60840
3176
01:16
and you were an obstacle in his way,
27
64040
1776
01:17
so he had to replan his path,
28
65840
2016
01:19
figure out where to go,
29
67880
1256
01:21
and then get there some other way,"
30
69160
1696
01:22
which was actually
not a very efficient thing to do.
31
70880
2456
01:25
If that robot had figured out
that I was a person, not a chair,
32
73360
3256
01:28
and that I was willing
to get out of its way
33
76640
2096
01:30
if it was trying to get somewhere,
34
78760
1656
01:32
then it actually
would have been more efficient
35
80440
2216
01:34
at getting its job done
36
82680
1256
01:35
if it had bothered
to notice that I was a human
37
83960
2216
01:38
and that I have different affordances
than things like chairs and walls do.
38
86200
3576
01:41
You know, we tend to think of these robots
as being from outer space
39
89800
3216
01:45
and from the future
and from science fiction,
40
93040
2136
01:47
and while that could be true,
41
95200
1416
01:48
I'd actually like to argue
that robots are here today,
42
96640
2656
01:51
and they live and work
amongst us right now.
43
99320
2776
01:54
These are two robots that live in my home.
44
102120
2856
01:57
They vacuum the floors
and they cut the grass
45
105000
2496
01:59
every single day,
46
107520
1216
02:00
which is more than I would do
if I actually had time to do these tasks,
47
108760
3376
02:04
and they probably
do it better than I would, too.
48
112160
2336
02:06
This one actually takes care of my kitty.
49
114520
2496
02:09
Every single time
he uses the box, it cleans it,
50
117040
2576
02:11
which is not something I'm willing to do,
51
119640
1976
02:13
and it actually makes
his life better as well as mine.
52
121640
2576
02:16
And while we call these robot products --
53
124240
2416
02:18
it's a "robot vacuum cleaner,
it's a robot lawnmower,
54
126680
2696
02:21
it's a robot littler box,"
55
129400
1495
02:22
I think there's actually a bunch
of other robots hiding in plain sight
56
130919
4137
02:27
that have just become so darn useful
57
135080
1856
02:28
and so darn mundane
58
136960
1456
02:30
that we call them things
like, "dishwasher," right?
59
138440
2496
02:32
They get new names.
60
140960
1216
02:34
They don't get called robot anymore
61
142200
1696
02:35
because they actually
serve a purpose in our lives.
62
143920
2416
02:38
Similarly, a thermostat, right?
63
146360
1496
02:39
I know my robotics friends out there
64
147880
1776
02:41
are probably cringing
at me calling this a robot,
65
149680
2336
02:44
but it has a goal.
66
152040
1256
02:45
Its goal is to make my house
66 degrees Fahrenheit,
67
153320
2896
02:48
and it senses the world.
68
156240
1256
02:49
It knows it's a little bit cold,
69
157520
1576
02:51
it makes a plan and then
it acts on the physical world.
70
159120
2616
02:53
It's robotics.
71
161760
1256
02:55
Even if it might not
look like Rosie the Robot,
72
163040
2576
02:57
it's doing something
that's really useful in my life
73
165640
2936
03:00
so I don't have to take care
74
168600
1376
03:02
of turning the temperature
up and down myself.
75
170000
2576
03:04
And I think these systems
live and work amongst us now,
76
172600
3816
03:08
and not only are these systems
living amongst us
77
176440
2336
03:10
but you are probably
a robot operator, too.
78
178800
2656
03:13
When you drive your car,
79
181480
1256
03:14
it feels like you are operating machinery.
80
182760
2216
03:17
You are also going
from point A to point B,
81
185000
2816
03:19
but your car probably has power steering,
82
187840
2216
03:22
it probably has automatic braking systems,
83
190080
2696
03:24
it might have an automatic transmission
and maybe even adaptive cruise control.
84
192800
3736
03:28
And while it might not be
a fully autonomous car,
85
196560
2936
03:31
it has bits of autonomy,
86
199520
1296
03:32
and they're so useful
87
200840
1336
03:34
and they make us drive safer,
88
202200
1816
03:36
and we just sort of feel
like they're invisible-in-use, right?
89
204040
3656
03:39
So when you're driving your car,
90
207720
1576
03:41
you should just feel like
you're going from one place to another.
91
209320
3096
03:44
It doesn't feel like it's this big thing
that you have to deal with and operate
92
212440
3736
03:48
and use these controls
93
216200
1256
03:49
because we spent so long
learning how to drive
94
217480
2176
03:51
that they've become
extensions of ourselves.
95
219680
2696
03:54
When you park that car
in that tight little garage space,
96
222400
2696
03:57
you know where your corners are.
97
225120
1576
03:58
And when you drive a rental car
that maybe you haven't driven before,
98
226720
3256
04:02
it takes some time
to get used to your new robot body.
99
230000
3056
04:05
And this is also true for people
who operate other types of robots,
100
233080
3976
04:09
so I'd like to share with you
a few stories about that.
101
237080
2600
04:12
Dealing with the problem
of remote collaboration.
102
240240
2336
04:14
So, at Willow Garage
I had a coworker named Dallas,
103
242600
2576
04:17
and Dallas looked like this.
104
245200
1576
04:18
He worked from his home in Indiana
in our company in California.
105
246800
4056
04:22
He was a voice in a box
on the table in most of our meetings,
106
250880
2936
04:25
which was kind of OK
except that, you know,
107
253840
2215
04:28
if we had a really heated debate
and we didn't like what he was saying,
108
256079
3377
04:31
we might just hang up on him.
109
259480
1416
04:32
(Laughter)
110
260920
1015
04:33
Then we might have a meeting
after that meeting
111
261959
2217
04:36
and actually make the decisions
in the hallway afterwards
112
264200
2696
04:38
when he wasn't there anymore.
113
266920
1416
04:40
So that wasn't so great for him.
114
268360
1576
04:41
And as a robotics company at Willow,
115
269960
1736
04:43
we had some extra
robot body parts laying around,
116
271720
2336
04:46
so Dallas and his buddy Curt
put together this thing,
117
274080
2496
04:48
which looks kind of
like Skype on a stick on wheels,
118
276600
2936
04:51
which seems like a techy, silly toy,
119
279560
1736
04:53
but really it's probably
one of the most powerful tools
120
281320
2776
04:56
that I've seen ever made
for remote collaboration.
121
284120
2480
04:59
So now, if I didn't answer
Dallas' email question,
122
287160
3496
05:02
he could literally roll into my office,
123
290680
2216
05:04
block my doorway
and ask me the question again --
124
292920
2576
05:07
(Laughter)
125
295520
1016
05:08
until I answered it.
126
296560
1216
05:09
And I'm not going to turn him off, right?
That's kind of rude.
127
297800
2976
05:12
Not only was it good
for these one-on-one communications,
128
300800
2696
05:15
but also for just showing up
at the company all-hands meeting.
129
303520
2936
05:18
Getting your butt in that chair
130
306480
1696
05:20
and showing people that you're present
and committed to your project
131
308200
3216
05:23
is a big deal
132
311440
1256
05:24
and can help remote collaboration a ton.
133
312720
2176
05:26
We saw this over the period
of months and then years,
134
314920
2856
05:29
not only at our company
but at others, too.
135
317800
2160
05:32
The best thing that can happen
with these systems
136
320720
2336
05:35
is that it starts to feel
like you're just there.
137
323080
2336
05:37
It's just you, it's just your body,
138
325440
1696
05:39
and so people actually start
to give these things personal space.
139
327160
3096
05:42
So when you're having a stand-up meeting,
140
330280
1976
05:44
people will stand around the space
141
332280
1656
05:45
just as they would
if you were there in person.
142
333960
2216
05:48
That's great until
there's breakdowns and it's not.
143
336200
2576
05:50
People, when they first see these robots,
144
338800
1976
05:52
are like, "Wow, where's the components?
There must be a camera over there,"
145
340800
3576
05:56
and they start poking your face.
146
344400
1576
05:58
"You're talking too softly,
I'm going to turn up your volume,"
147
346000
2936
06:00
which is like having a coworker
walk up to you and say,
148
348960
2616
06:03
"You're speaking too softly,
I'm going to turn up your face."
149
351600
2896
06:06
That's awkward and not OK,
150
354520
1256
06:07
and so we end up having to build
these new social norms
151
355800
2616
06:10
around using these systems.
152
358440
2216
06:12
Similarly, as you start
feeling like it's your body,
153
360680
3416
06:16
you start noticing things like,
"Oh, my robot is kind of short."
154
364120
3696
06:19
Dallas would say things to me --
he was six-foot tall --
155
367840
2656
06:22
and we would take him via robot
to cocktail parties and things like that,
156
370520
3456
06:26
as you do,
157
374000
1216
06:27
and the robot was about five-foot-tall,
which is close to my height.
158
375240
3336
06:30
And he would tell me,
159
378600
1216
06:31
"You know, people are not
really looking at me.
160
379840
2536
06:34
I feel like I'm just looking
at this sea of shoulders,
161
382400
2696
06:37
and it's just -- we need a taller robot."
162
385120
1976
06:39
And I told him,
163
387120
1256
06:40
"Um, no.
164
388400
1296
06:41
You get to walk in my shoes for today.
165
389720
1936
06:43
You get to see what it's like
to be on the shorter end of the spectrum."
166
391680
3536
06:47
And he actually ended up building
a lot of empathy for that experience,
167
395240
3376
06:50
which was kind of great.
168
398640
1256
06:51
So when he'd come visit in person,
169
399920
1656
06:53
he no longer stood over me
as he was talking to me,
170
401600
2416
06:56
he would sit down
and talk to me eye to eye,
171
404040
2096
06:58
which was kind of a beautiful thing.
172
406160
1736
06:59
So we actually decided
to look at this in the laboratory
173
407920
2656
07:02
and see what others kinds of differences
things like robot height would make.
174
410600
3656
07:06
And so half of the people in our study
used a shorter robot,
175
414280
2856
07:09
half of the people in our study
used a taller robot
176
417160
2416
07:11
and we actually found
that the exact same person
177
419600
2256
07:13
who has the exact same body
and says the exact same things as someone,
178
421880
3336
07:17
is more persuasive
and perceived as being more credible
179
425240
2616
07:19
if they're in a taller robot form.
180
427880
1656
07:21
It makes no rational sense,
181
429560
1816
07:23
but that's why we study psychology.
182
431400
1696
07:25
And really, you know,
the way that Cliff Nass would put this
183
433120
2856
07:28
is that we're having to deal
with these new technologies
184
436000
3016
07:31
despite the fact
that we have very old brains.
185
439040
2736
07:33
Human psychology is not changing
at the same speed that tech is
186
441800
2976
07:36
and so we're always playing catch-up,
187
444800
1816
07:38
trying to make sense of this world
188
446640
1656
07:40
where these autonomous things
are running around.
189
448320
2336
07:42
Usually, things that talk are people,
not machines, right?
190
450680
2736
07:45
And so we breathe a lot of meaning
into things like just height of a machine,
191
453440
4576
07:50
not a person,
192
458040
1256
07:51
and attribute that
to the person using the system.
193
459320
2360
07:55
You know, this, I think,
is really important
194
463120
2216
07:57
when you're thinking about robotics.
195
465360
1736
07:59
It's not so much about reinventing humans,
196
467120
2096
08:01
it's more about figuring out
how we extend ourselves, right?
197
469240
3136
08:04
And we end up using things
in ways that are sort of surprising.
198
472400
2976
08:07
So these guys can't play pool
because the robots don't have arms,
199
475400
4256
08:11
but they can heckle the guys
who are playing pool
200
479680
2336
08:14
and that can be an important thing
for team bonding,
201
482040
3176
08:17
which is kind of neat.
202
485240
1296
08:18
People who get really good
at operating these systems
203
486560
2496
08:21
will even do things
like make up new games,
204
489080
2056
08:23
like robot soccer
in the middle of the night,
205
491160
2136
08:25
pushing the trash cans around.
206
493320
1456
08:26
But not everyone's good.
207
494800
1576
08:28
A lot of people have trouble
operating these systems.
208
496400
2496
08:30
This is actually a guy
who logged into the robot
209
498920
2256
08:33
and his eyeball was turned
90 degrees to the left.
210
501200
2376
08:35
He didn't know that,
211
503600
1256
08:36
so he ended up just bashing
around the office,
212
504880
2176
08:39
running into people's desks,
getting super embarrassed,
213
507080
2616
08:41
laughing about it --
his volume was way too high.
214
509720
2336
08:44
And this guy here
in the image is telling me,
215
512080
2136
08:46
"We need a robot mute button."
216
514240
2096
08:48
And by that what he really meant
was we don't want it to be so disruptive.
217
516360
3496
08:51
So as a robotics company,
218
519880
1616
08:53
we added some obstacle
avoidance to the system.
219
521520
2456
08:56
It got a little laser range finder
that could see the obstacles,
220
524000
3056
08:59
and if I as a robot operator
try to say, run into a chair,
221
527080
3136
09:02
it wouldn't let me,
it would just plan a path around,
222
530240
2496
09:04
which seems like a good idea.
223
532760
1856
09:06
People did hit fewer obstacles
using that system, obviously,
224
534640
3176
09:09
but actually, for some of the people,
225
537840
2096
09:11
it took them a lot longer
to get through our obstacle course,
226
539960
2856
09:14
and we wanted to know why.
227
542840
1560
09:17
It turns out that there's
this important human dimension --
228
545080
3056
09:20
a personality dimension
called locus of control,
229
548160
2296
09:22
and people who have
a strong internal locus of control,
230
550480
3136
09:25
they need to be the masters
of their own destiny --
231
553640
3056
09:28
really don't like giving up control
to an autonomous system --
232
556720
3096
09:31
so much so that they will
fight the autonomy;
233
559840
2136
09:34
"If I want to hit that chair,
I'm going to hit that chair."
234
562000
3096
09:37
And so they would actually suffer
from having that autonomous assistance,
235
565120
3616
09:40
which is an important thing for us to know
236
568760
2576
09:43
as we're building increasingly
autonomous, say, cars, right?
237
571360
3296
09:46
How are different people going
to grapple with that loss of control?
238
574680
3360
09:50
It's going to be different
depending on human dimensions.
239
578880
2696
09:53
We can't treat humans
as if we're just one monolithic thing.
240
581600
3496
09:57
We vary by personality, by culture,
241
585120
2416
09:59
we even vary by emotional state
moment to moment,
242
587560
2456
10:02
and being able to design these systems,
243
590040
1976
10:04
these human-robot interaction systems,
244
592040
2296
10:06
we need to take into account
the human dimensions,
245
594360
2736
10:09
not just the technological ones.
246
597120
1720
10:11
Along with a sense of control
also comes a sense of responsibility.
247
599640
4296
10:15
And if you were a robot operator
using one of these systems,
248
603960
2856
10:18
this is what the interface
would look like.
249
606840
2056
10:20
It looks a little bit like a video game,
250
608920
1936
10:22
which can be good because
that's very familiar to people,
251
610880
2976
10:25
but it can also be bad
252
613880
1216
10:27
because it makes people feel
like it's a video game.
253
615120
2456
10:29
We had a bunch of kids
over at Stanford play with the system
254
617600
2856
10:32
and drive the robot
around our office in Menlo Park,
255
620480
2456
10:34
and the kids started saying things like,
256
622960
1936
10:36
"10 points if you hit that guy over there.
20 points for that one."
257
624920
3176
10:40
And they would
chase them down the hallway.
258
628120
2016
10:42
(Laughter)
259
630160
1016
10:43
I told them, "Um, those are real people.
260
631200
1936
10:45
They're actually going to bleed
and feel pain if you hit them."
261
633160
3296
10:48
And they'd be like, "OK, got it."
262
636480
1616
10:50
But five minutes later,
they would be like,
263
638120
2056
10:52
"20 points for that guy over there,
he just looks like he needs to get hit."
264
640200
3616
10:55
It's a little bit
like "Ender's Game," right?
265
643840
2136
10:58
There is a real world on that other side
266
646000
1936
10:59
and I think it's our responsibility
as people designing these interfaces
267
647960
3416
11:03
to help people remember
268
651400
1256
11:04
that there's real consequences
to their actions
269
652680
2256
11:06
and to feel a sense of responsibility
270
654960
2296
11:09
when they're operating
these increasingly autonomous things.
271
657280
3280
11:13
These are kind of a great example
272
661840
2296
11:16
of experimenting with one
possible robotic future,
273
664160
3256
11:19
and I think it's pretty cool
that we can extend ourselves
274
667440
3856
11:23
and learn about the ways
that we extend ourselves
275
671320
2336
11:25
into these machines
276
673680
1216
11:26
while at the same time
being able to express our humanity
277
674920
2696
11:29
and our personality.
278
677640
1216
11:30
We also build empathy for others
279
678880
1576
11:32
in terms of being
shorter, taller, faster, slower,
280
680480
3216
11:35
and maybe even armless,
281
683720
1416
11:37
which is kind of neat.
282
685160
1336
11:38
We also build empathy
for the robots themselves.
283
686520
2536
11:41
This is one of my favorite robots.
284
689080
1656
11:42
It's called the Tweenbot.
285
690760
1456
11:44
And this guy has a little flag that says,
286
692240
1976
11:46
"I'm trying to get
to this intersection in Manhattan,"
287
694240
2576
11:48
and it's cute and rolls
forward, that's it.
288
696840
2776
11:51
It doesn't know how to build a map,
it doesn't know how to see the world,
289
699640
3456
11:55
it just asks for help.
290
703120
1256
11:56
The nice thing about people
291
704400
1336
11:57
is that it can actually depend
upon the kindness of strangers.
292
705760
3096
12:00
It did make it across the park
to the other side of Manhattan --
293
708880
3896
12:04
which is pretty great --
294
712800
1256
12:06
just because people would pick it up
and point it in the right direction.
295
714080
3456
12:09
(Laughter)
296
717560
936
12:10
And that's great, right?
297
718520
1256
12:11
We're trying to build
this human-robot world
298
719800
2696
12:14
in which we can coexist
and collaborate with one another,
299
722520
3416
12:17
and we don't need to be fully autonomous
and just do things on our own.
300
725960
3376
12:21
We actually do things together.
301
729360
1496
12:22
And to make that happen,
302
730880
1256
12:24
we actually need help from people
like the artists and the designers,
303
732160
3256
12:27
the policy makers, the legal scholars,
304
735440
1856
12:29
psychologists, sociologists,
anthropologists --
305
737320
2216
12:31
we need more perspectives in the room
306
739560
1816
12:33
if we're going to do the thing
that Stu Card says we should do,
307
741400
2976
12:36
which is invent the future
that we actually want to live in.
308
744400
3936
12:40
And I think we can continue to experiment
309
748360
2656
12:43
with these different
robotic futures together,
310
751040
2176
12:45
and in doing so, we will end up
learning a lot more about ourselves.
311
753240
4680
12:50
Thank you.
312
758720
1216
12:51
