So robots.
Robots can be programmed to do the same task millions of times
with minimal error, something very difficult for us, right?
And it can be very impressive to watch them at work.
Look at them.
I could watch them for hours.
No?
But what is less impressive that if you take this robot
out of the factories
where the environments are not perfectly known and measured like here,
to do even a simple task which doesn't require much precision,
and this is what can happen.
I mean, opening a door, you don't require much precision.
(Laughter)
Or, a small error in the measurements,
you miss the ?? and that's it.
