A robot dog named Spot is now a part of the team that protects important people in the United States. Spot works for the US Secret Service. This robot dog walks around the outside of a big house in Florida where President-elect Donald Trump stays. Spot does not have weapons. People can control Spot from far away or Spot can move on its own if they tell it where to go first. There is a sign on Spot that says, "Do not touch."

Spot has become very popular on the internet. Many people have seen videos of Spot and have different feelings about it. Some people think Spot is cool or cute, and some think Spot is scary. But Spot has a serious job. Spot helps to keep the president-elect safe. The Secret Service, which is the group that protects the president-elect, does not talk much about how they use Spot. They want to keep their work secret. The company that made Spot, Boston Dynamics, also does not say much. But they say the Secret Service is using Spot.

Spot is very good at moving around. It can walk up and down stairs and go into small spaces. It can even open doors. Spot has cameras that help it see where it is going. It can also have special tools to see heat. Spot needs a person to control it. People use something like a video game controller to tell Spot where to go. Spot can also move by itself if it knows the way. Spot is not the only robot dog. Other places in the world use robot dogs too. They help the police and the army. But even with all these robot dogs, we still need people. People make sure everything is working right. They make decisions and help if the robot dogs stop working.
