During a manned mission, you have to keep the man alive and coherent. This means taking food, air, and water into space, as well as designing the spacecraft with enough empty space to be occupied by the human body and a mission timeline that allows for sleeping and rest of the crew member. Secondly, a mission failure means potential loss of human life. None of these provisions need to be taken into account for robotic missions.
