In Tianjin, China, a group of people are waiting at the bus stop. Soon, the bus comes to the bus stop. It isn't the same bus as we usually see on the street. It looks like a panda with black ears and black eyes. After getting on the bus, people only need to buy their tickets by scanning(扫描)their hands! About one minute later, the bus begins its self-driving mode. It stops for traffic lights automatically(自动的)before it gets to the next stop. That is to say, it can drive and stop by itself.
There are also some robots on the bus. People can talk to them and ask them for help. If there is a bad person on the bus, the robots will call the police. "It's very convenient. " says a woman taking the bus. "And kids love it. "
