In French, you would typically use "tu" when talking to someone you know well, such as a friend or a peer, and "vous" when addressing someone more formally or someone you do not know well.
Since "Robert" is a name and lacks context about your relationship with this person, if Robert is a friend or someone you are familiar with, you would use "tu." If he is someone you do not know well or if you wish to show respect, you would use "vous."
Please select "Otu" or "Ovous" based on the intended familiarity or formality. If you are unsure, "Ovous" might be the safer choice.
