1
99:59:59,999 --> 99:59:59,999
So robots.

2
99:59:59,999 --> 99:59:59,999
Robots can be programmed
to do the same task millions of times

3
99:59:59,999 --> 99:59:59,999
with minimal error, something
very difficult for us, right?

4
99:59:59,999 --> 99:59:59,999
And it can be very impressive
to watch them at work.

5
99:59:59,999 --> 99:59:59,999
Look at them.

6
99:59:59,999 --> 99:59:59,999
I could watch them for hours.

7
99:59:59,999 --> 99:59:59,999
No?

8
99:59:59,999 --> 99:59:59,999
But what is less impressive
that if you take this robot

9
99:59:59,999 --> 99:59:59,999
out of the factories

10
99:59:59,999 --> 99:59:59,999
where the environments are not
perfectly known and measured like here,

11
99:59:59,999 --> 99:59:59,999
to do even a simple task
which doesn't require much precision,

12
99:59:59,999 --> 99:59:59,999
and this is what can happen.

13
99:59:59,999 --> 99:59:59,999
I mean, opening a door,
you don't require much precision.

14
99:59:59,999 --> 99:59:59,999
(Laughter)

15
99:59:59,999 --> 99:59:59,999
Or, a small error in the measurements,

16
99:59:59,999 --> 99:59:59,999
you miss the ?? and that's it.
