New robot dog being used!
In Munich, Germany, there's a new plan to stop people from painting graffiti [[graffiti::drawings or writing scribbled on a wall or surface]] on trains. It's a robot dog! The robot is called Spot, and it was made by a company called Boston Dynamics.
Spot uses artificial intelligence [[artificial intelligence::computer programs that can think and learn like humans]] (AI) to help it find people spray-painting on trains.
How does Spot work?
Spot is very clever! It has looked at 1,200 pictures of graffiti to learn what it looks like. When Spot sees someone doing graffiti, it sends a video to the security [[security::a team that keeps people and things safe]] team. The team checks the video and decides what to do next.
This robot dog is part of a test by two train companies, Deutsche Bahn (DB) and Munich S-Bahn. They are testing Spot for four weeks. If it works well, they may use Spot more often!
Why do they need Spot?
Graffiti is a big problem in Germany. People paint trains with spray paint. This costs the train companies a lot of money to clean them. It also takes time to clean the trains before they can run again. Spot can help stop this problem.
What do you think? Could robot dogs help in other ways, too?
