Robots play a role in elder care

Japan hopes to fill shortfall of specialized workers by 2025

TOKYO - Paro the furry seal cries softly while an elderly woman pets it. Pepper, a humanoid, waves while leading a group of senior citizens in exercises. The upright Tree guides a disabled man taking shaky steps, saying in a gentle feminine voice, "right, left, well done!"

Robots have the run of Tokyo's Shin-tomi nursing home, which uses 20 different models to care for its residents. The Japanese government hopes it will be a model for harnessing the country's robotics expertise to help cope with a swelling elderly population and dwindling workforce.
