I already said. You're confined in a fragile environment. Anything goes around you'll die. You'll have insufficient oxygen, or too much CO2, or your food will get a disease, or your biosphere will spring a leak. All kinds of shit can go wrong. It's an incredibly fragile and isolated ecosystem. Go read about Biosphere 2 and what actually happened.

But why can't we just order robots to grow whatever we need.

I just don't see it. Biosphere 2 was small scale, had limited reserves of oxygen etc. A sealed biodome on earth can pull in oxygen still from the earths atmosphere even if it is sterile or full of bioweapons or radioactive etc.
