Problem statement and objectives

With about one-third of the world’s population living under some form of quarantine due to the COVID-19 outbreak , scientists sound the alarm on the negative psychological effects of the current situation [2]. Studies on the impact of massive self-isolation in the past, such as in Canada and China in 2003 during the SARS outbreak or in west African countries caused by Ebola in 2014, have shown that the psychological side effects of quarantine can be observed several months or even years after an epidemic is contained [3]. Among others, prolong self-isolation may lead to higher risk of depression, anxiety, poor concentration and lowered motivation level [2]. The negative effects on well-being can be mitigated by introducing measurements which help in the process of accommodation to a new situation during the quarantine. Such measurements should aim at reducing the boredom (1), improving the communication within a social network (2) and keeping people informed (3) [2]. With the following project, we propose an in-house assistant that addresses these three objectives. Although the assistant is designed with a view of self-isolation caused by disease outbreak, it is also applicable for people who spend a considerable part of their time at home.

Approach

In order for us to tackle the problem as described in the problem statement, we will start with careful research on topics that require our attention, like how and where we can support mental and physical health of people. From this research, we can create a solution consisting of different disciplines and techniques.

From there, we will start building an assistant that has the following features:

• Speech:
  • Text to speech (TTS): being able to interact with an assistant via speech is a key part of the assistant, to tackle the loneliness problem. Using hardware microphones and pre-existing software, we can create a ‘living’ assistant.
  • Speech to text (STT): being able to talk back to the assistant sparks up the conversation, and makes the assistant more human-like.
• Engaging in conversation: the robot has functionalities to hear people, and talk back, but maintaining context and having a real conversation is very important.
• Movement: the robot has functionalities that enable it to move around a surface, and autonomously move around obstacles to reach some target.
• Exercising: to counter the lack of physical activities, the robot has functionalities that can prompt or motivate the user to be physically active, and to track the user’s activity.
• General information: the robot prompts the user to hear the latest news twice every day, once in the morning and once in the evening. Users can always request a new update through a voice command.
• Graphical User Interface: when the user is unable to talk to the assistant, there will be an option to interact with a graphical user interface, displayed on a touch screen. InterFACE.
• Vision: skeleton tracking, facial detection. Use this data to count jumping jacks, look at someone when talking to. (Closely linked with navigation)
• Navigation: TODO

Using different feature sets allows our team members to (partly) work individually, speeding up the development process in the difficult time that we are in right now. The parts should be tested together. Not only in the end, but also when building. This can be done by scheduling meetings with the person responsible for building the physical robot. The team members can share code via a source like GitHub, which then can be uploaded onto the robot, allowing members to test their part.

When all parts work together, a video will be created, highlighting all bot functionalities.

Deliverables

By the end of the project, we will deliver the following items:

• Project Description (report via wiki)
• Project Video demonstrating functionalities
• Physical assistant
• Source code
