IDP: Group 4: walking a route

**Design problem:** The HR has to monitor of the PwD is staying on route while engaging in smalltalk.

**Design solution:** In this design pattern, the HR monitors the route through its sonar sensor and kindly correts the PwD if they go off route. Furthermore they will ask simple questions about the weather and environment and respond accurately to the PwD.

**Example: **In our use case (i.e. "activity" as specified by group 4 of the SCE-course in 2023), Pepper and the PwD walk side-by-side with Pepper adjusting to the PwD's tempo. In case the PwD goes off route, Pepper says "please follow me to stay on route" and goes in front. Afterwards they go side by side again. While walking, Pepper asks questions like "What do you t think of the weather today?" and "Do you like the plants in the garden?" For detail on the parameter setting, see the Table below (WIP).
