A special robot show is happening in Beijing! It’s all about “nanny robots” —kind helpers for families.

These robots do many things. They play games with children, tell stories, and help grandparents stand up safely.

Safety is key! Robots use cameras and sensors (传感器) to watch over children playing or grandparents resting. If someone might fall, they warn gently.

Before chores, some robots give a confident OK sign! They tidy toys for kids, prepare medicine for elders, and remind everyone to drink water.

But these robots don’t replace (取代) people. They’re friendly helpers making life safer, easier, and happier for all ages!
