The article

It would depend. Is it a name or a description (which may also be used as a name). Consider :

a) "Here at "Robots and Agents Lab", we supply robots and agents whenever requested by customers."

b) "If you need a robot or agent, I suggest that you make an appointment with the Robots and Agents Lab."

I suspect b) is more what you meant.

Kind regards, Michael

Thanks.

It's a title of a person: "Director of the Robots and Agents Lab"

or could be used in a sentence like: "He is the Director of the Robots and Agents Lab"

so 'the' is required?

Probably. It still depends on what "Robots and Agents Lab" is. If it's the trading name of a business, then no, but otherwise, probably yes.

I believe "Robots and Agents Lab" is a proper name, it does not mean that the lab provides robots or agents.

So it may not need the article then, right?

I just don't know. What does the lab do? I need context to help you. Can you post a whole sentence including this?
