But can robots really take the place of humans? 2 can they do for us in the future? Let’s find out. Some robots look like humans, while others look like machines. They are 3 at doing repetitive jobs without getting tired. What’s more, with the help of AI, they can learn from their mistakes. This means the more they work, the 4 they will become. So robots are quite 5 from humans in some ways. 6 useful helpers robots are! Robots are great, but they still have limitations. They cannot feel emotions or understand human feelings deeply.
