Due to the demographic changes in modern society, there has been an explosive increase in the population aged 80 and above worldwide. As a result, I focused on how to improve the quality of life for the elderly, who often face issues such as loneliness and depression.Elderly individuals with mobility difficulties often lose opportunities for active interaction with their families or other elderly people due to physical limitations or emotional distance. To address the issue of lonely lives among the elderly, I proposed Roobin, a companion social robot, for Van Breda, a manufacturer of robots and healthcare-based IoT systems.

Acceptance of Robots Among the Elderly

To accommodate elderly users who are not familiar with displays or new interfaces, the design of Roobin prioritized intuitive usability. Notably, I believed that a hardware-based approach, such as expressions, nodding, and the use of LEDs, would enhance the acceptance of robots among the elderly more effectively than a software-based approach. Therefore, the design focused on hardware elements. Additionally, by incorporating voice-based communication, we aimed to minimize any difficulties elderly users might experience when interacting with the robot.

Hardware Prototyping Using 3D Printing, Raspberry Pi, and Arduino

The prototype's exterior was created using 3D printing technology. To implement various movements of the robot, controllers such as Raspberry Pi and Arduino were used internally.

Roobin Application: Connecting the Elderly with Society

The Roobin application is designed with the goal of connecting elderly users with others. Many elderly individuals choose not to move into nursing homes in order to maintain their familiar lifestyle, but they often need assistance from others in their daily lives due to physical or cognitive limitations. Particularly in emergencies, appropriate actions need to be taken immediately to avoid medical risks. Therefore, the application notifies caregivers and medical institutions in emergency situations, enabling elderly individuals to respond more quickly to crises.Additionally, the Roobin application collects comprehensive information about the health conditions that elderly users face at home, providing supportive data for medical decision-making. Moreover, in daily life, the application suggests activities that encourage social participation for the elderly and offers options for easily contacting registered acquaintances, helping them maintain a mentally healthier lifestyle.
