TPD: Group 4

Version 2.1 by Hugo van Dijk on 2023/03/09 12:51

 Group 4:

ProblemThe Humanoid Robot has to manage the amount of physical activities the PwD in the carehome did. He has to motivate the person with the lowest count to go on a walk in the garden. He will use either goal-based or motivation-based explanations for his motivation. He has to accompany the PwD on their walks. While walking he manages the route and provides smalltalk.

Solution Description

All actors (caretaker, humanoid robot, players) are co-located

  1. The robot monitors the activities done by all PwD in the carehome as well as the current weather.
  2. The caretaker supervises the robot to check if it is operating safely
  3. PwD is unaware of this at the moment.
  4. The robot goes up to the PwD with a low activity level and tries to motivate them to join him for a walk in the garden.
  5. The PwD responds to the robot
  6. The robot monitors values related to safety for the PwD (like responsiveness & movement)
  7. The robot gives multiple options for routes to walk
  8. The PwD chooses one of the options.
  9. The PwD walks with the robot
  10. The robot uses GPS to monitor the route and corrects the PwD if they are going the wrong way.
  11. The robot makes small talk during the walk.
  12. The PwD responds to the robot.
Human RQ
  • PwD: able to walk and interact with robot
  • Caretaker: know the vulnerabilities of all PwD and understand the limits of the Robot.
Machine RQ
  • Check activity
    • Have a way of monitoring movement of all PwD
    • Have a db with activity per PwD
    • Able to choose PwD (that is able to walk) with lowest activity level
    • Know current weather outside
  • Motivate
    • Be able to find and go up to the PwD
    • Don't ask too often (to not be annoying)
    • Have some basic info about the PwD to help with motivation.
    • Be able to perceive PwD's reaction (speech and vision)
  • Supervise safety
    • Be able to perceive PwD's response level (speech and vision)
    • Be able to perceive PwD's movement (vision)
  • Give route options
    • Know multiple safe routes through the garden
    • Communicate route options clearly (text or visual)
  • Monitor route
    • Have way of tracking route (sonar/cameras)
    • Move at walking speed
    • Communicate correction
  • Small talk
    • Have arsenal of interesting (relatively simple) topics/questions
    • Handle responses adaptively
Consequences

+ Offload of caretaker so that they can focus on more involving health related activities

+ Healthy for PwD

+ Sense of independency

+ Social for PwD

- Robot can be perceived as annoying and thus ignored by PwD

- Privacy issues

- Hardware limitations of robot

Grounding

Action sequence Observation scene:

1. Check activity level of all PwD

2. Choose lowest for PwD that is able to walk

3. The CT verifies the choice

Action sequence Motivation scene:

  1. Find and go up to PwD
  2. Ask to go outside
  3. Provide relevant explanation
  4. Respond to PwD's responses

Action sequence Activity scene:

  1. HR Provides route options (explain of display)
  2. PwD chooses option
  3. HR selects route option
  4. HR starts walking at same speed as PwD
  5. HR monitors route and corrects if PwD goes off route
  6. HR asks simple question (like "what do you think of the weather?")
  7. PwD responds
  8. HR handles response
  9. Repeat step 6 until done walking.
  10. Both go back inside
  11. HR thanks the PwD.
