Those robots. You're good at getting out of their way if you have to and it sounds like you've got a good eye for this sort of thing. Do you think you'd be able to keep an eye on them and tell me what they get up to at night?

It doesn't have to be very often -- and it doesn't have to be for the whole night, either. I just want us to get a better idea of what they're doing when the rest of us are in bed.
