Environments

Possible environments in which a PwD lives:

• Environment: Person 1
  In a nursing home where there are 100 other people who have a physical or mental disability and each of them has their own room

• Environment: Person 2
  In a daycare centre with 50 other people. He/She is dropped off every day at 8:00h and picked up at 18:00h. 

• Environment: Person 3
  Lives at home with family. The family consists of their child and spouse along with the two grandchildren.

• Social Environment in care center
  The care center has different rooms like living room and puzzles room which support food, beverages and puzzle games respectively. These activities take place at specific periods of the day. The PwD patients are not allowed to go out of the center alone as this can be risky, therefore need a caretaker to accompany them.

Requirements for the environment

• reachable door
  The room or house has to have a door. The door should never be out of the robot's reach (no loss of connection to sensor, no stairways) so that the robot can always reach the door and help the patient.

• gate between safe/ unsafe environment for PwD
  The door should separate the care home from the 'outside', where the patient is not allowed to go (alone). Best case it's the only door leading outwards. 

Application
From these requirements follows that in our case we need to cover the main entrance/ exit door of the care center. We will locate the robot inside the building, in front of the door like a Bouncer. This has the advantage that PwDs are still able to walk around in the building but are prevented from wandering outside.
Furthermore using the robot as door guard has the advantage that only one robot for many Patients is needed. This saves money in terms of acquisition costs and maintenance costs.
