日本小镇机器人送餐暖人心
In a quiet town in Japan, a small robot now helps older people. It is white and round, with bright friendly eyes. It is not tall, just up to your knee. Its name is 'Food Friend.'
Every morning, a volunteer fills the robot with warm food. The food comes from the town kitchen. The robot then rolls slowly along the sidewalk. It knows the way because it has a little camera.
