The general problem is stated well. It would be good to briefly describe an instance of the problem for one of your personas. Further, it is good that you already envision the role of the robot. Actually, that part is the "design scenario". Give this part the title "design scenario" and describe the same instance of the persona with a robot (to show the role and envisioned benefits of the robot).
