Introduction to Singapore's Robotics in Eldercare
Singapore, a 'Smart Nation', is at the forefront of integrating technology into healthcare, especially for its aging demographics. This approach is crucial for addressing manpower shortages and empowering seniors to live independently and comfortably at home. Robots are deployed across several key areas: social companionship, physical wellness, mobility assistance, and service delivery.
The Rise of Companion and Social Robots
Combatting loneliness and promoting mental well-being is a critical function of robotics in eldercare. Social robots offer interactive engagement that can be beneficial, particularly during periods of isolation. Changi General Hospital and other institutions in Singapore have trialed various social robots, with promising results.
- Daisy: A humanoid co-worker deployed in nursing homes, Daisy relieves staff from repetitive engagement duties, allowing them to focus on more meaningful interactions with residents. By leading activities like bingo, Daisy supports the emotional and cognitive health of older adults.
- Paro: This robotic baby seal, a cuddly, touch-reactive therapeutic tool, has been shown to reduce stress and anxiety in dementia patients. Its soothing qualities can help manage challenging behaviors and, in some cases, reduce the need for sedative medication.
- KEBBI Air & LOVOT: A Taiwanese-made desktop companion, KEBBI Air converses with people, while the Japanese-made LOVOT is a social robot that promotes feelings of happiness and connection. These robots enrich social interaction, especially for residents in care homes who may be under-engaged.
- Naen: Created by Singapore-based Professor Nadia Thalman, Naen is a humanoid social robot that can play bingo with residents and interact with them based on their needs. Its advanced AI includes memory and an emotional model, enabling situational awareness.
Advancements in Physical Wellness and Mobility
Physical health and mobility are central to maintaining independence. Robotics in this area focuses on preventing accidents and assisting with physical activity.
- RoboCoach (Xuan): Developed by Ngee Ann Polytechnic, this humanoid exercise robot leads seniors in guided fitness routines at senior activity centers. It uses sensors to ensure correct form, provides encouragement, and can respond to voice commands, making exercise more engaging and safer.
- Mobile Robotic Balance Assistant (MRBA): A wearable assistive device developed by Nanyang Technological University, the MRBA uses sensors to detect a loss of balance and prevent falls by catching the wearer with a safety harness. It also helps with physical therapy exercises and sitting/standing assistance. The device aims to promote independent living and has undergone clinical trials with positive results.
Autonomous Service and Delivery Robots
Addressing logistical needs frees up human caregivers and promotes efficiency. Delivery robots offer a reliable way to get essentials to seniors, especially those living in high-density public housing (HDB) flats.
- Aiden: This autonomous robot delivers items like food and medicine to seniors in HDB blocks. It navigates complex environments like narrow corridors and lifts with ease. Pilots have shown that Aiden can simplify daily life and allow staff to focus on more complex care needs. Aiden is being refined and tested in real-world scenarios to integrate seamlessly into daily community life.
Singapore's Strategic Approach: 'High Tech, High Touch'
Singapore's government recognizes that technology should complement, not replace, human caregivers. The strategy is described as 'high tech, high touch,' where AI and robots serve as extra sets of eyes, ears, and hands to support a person-centric approach to caregiving. The government's "Action Plan for Successful Ageing" includes a focus on using AI to assist in preventive illness care and monitoring seniors' health at home. A balanced approach is emphasized, one that respects the autonomy of seniors and tailors technology to their needs.

The Future of Eldercare Robotics in Singapore
The continued development of robots like Aiden and MRBA, combined with the successful deployment of social companions like Daisy and Paro, demonstrates Singapore's commitment to tech-enabled eldercare. Integrating AI into home monitoring systems for fall detection is also a growing area. As research expands, particularly in community and home settings, these technologies will become more refined and accessible, ensuring Singapore's seniors can age with dignity and independence, supported by an advanced, compassionate network of care.
