Okay, so there was this cute little robot named Hitchbot. It's shaped like a person and its job was to travel around and meet new people. It wanted to learn about different places and cultures.
Hitchbot didn't drive a car or walk. Instead, it was designed to catch rides with friendly people. People would pick it up and take it places. They'd talk to it, take pictures with it, and help it learn new things.
Hitchbot had a very special skill, too. It could talk back to people! It could say things like "hello" and "thank you" and answer questions. It was very smart and could understand when people were talking to it.
Unfortunately, one day Hitchbot was put in a bad situation and it couldn't continue its travels. But, lots of people remember Hitchbot and how it brought many people together during its journey.
