Robotic nurses with cute bear faces developed by Japanese engineers could soon be the future carers of the nation's growing elderly population.
Japanese research institute Riken developed the Robear to support healthcare workers, with enough power to lift frail patients from bed and support unstable patients on their feet.
The Robear is based on an earlier model called RIBA, which was introduced in 2011. The upgraded Robear is about 90 kilograms lighter than its predecessor, capable of more subtle movements and sports an even cuter look.
"The polar cub-like look is aimed at radiating an atmosphere of strength, geniality and cleanliness at the same time," research leader Toshiharu Mukai said.
"We voted for this design among options presented by our designer. We hope to commercialise the robot in the not too distant future."
A historically low birth rate and ever-increasing life expectancy means Japan's population of elderly people is growing, while the pool of youngsters to look after them is shrinking.
Japan's declining population puts it on course to lose half its workforce by 2060, and possibly its status as an economic superpower.
Despite calls for large-scale immigration into the racially homogenous country, residents remain reluctant, meaning an increasing reliance on robots, especially to perform physically difficult work.
This frequently combines with the country's love of all things cute, to produce machines with disarming faces and child-like voices.
Riken said it aimed to combat the burden Japan's ageing population would place on the healthcare system.
"As Japan is ageing with fewer children, the problem of a shortage in caregivers for the elderly is getting serious," Riken said in a statement.
"Expectations are high that robotics will help resolve this problem."
