This summer, small robots returned to city sidewalks in America. A delivery robot is a small machine with wheels. It carries food from a restaurant to a home. A worker puts the meal inside its locked box. Then the robot moves along the sidewalk. People can watch its trip on an app. At home, the customer opens the box. (axios.com)
Imagine you come home tired after work. You order rice, chicken, and a warm drink. Soon, a little robot brings your dinner. It may look like a moving lunchbox! Robots can help during busy dinner hours. They must also share sidewalks safely with people. (axios.com)
