Companion(同伴)robots are playing an ever-increasing role in helping busy people look after the elderly and children. With an aging population and an increasing labor shortage, the demand for companion robots for elder care and children’s companions is on the rise.

Xiaoyuzaijia is an intelligent companion robot produced by Zaijia.com, a Beijing-based startup engaged in internet hardware and intelligent home appliances businesses.

If the elderly people are ill at home, the robot can bring medicine and water. The robot will open the door when the guest comes. It can even tell a story, sing a song and play chess.

The number of elderly people aged 60 and above reached more than 222 million in 2015, accounting for 16.2 percent of the total population, according to the National Bureau of Statistics. It is estimated that the number will reach 243 million in 2020.

Song Chenfeng, founder and CEO of Zaijia, said: "The robot is equipped with a monitoring camera and other hardware for facial and voice recognition.” Family members could also connect their smart phones with the robot. “When the elderly fall or the children cry at home, the robot will send messages to inform other family members," he said. “The companion robot should be an important 'blue sea' in the intelligent household robot market. Xiaoyuzaijia aims at white-collar people who are busy with their work and spend less time accompanying their family members. It builds a bridge among family members and satisfies the emotional communications needs of modern people,” said Song.

Yuan Wenhui, chairman of Zaijia, said the company will offer personalized service in the family healthcare and children's education sectors, based on big data algorithms, aiming to be an indispensable intelligent family housekeeper in the future.

Statistics from the International Federation of Robotics show that the market demand for service robots will boom in the next three years, with the market scale reaching $46 billion.
