I think robots are really useful in our daily life. They can help with some dangerous work like working on high buildings. They can also do some boring jobs that people are easily bored with. I consider them as helpers to humans. These days I often find one kind of robots in some restaurants. They can help send dishes to customers. How clever! This saves lots of money and time as well as brings customers much fun. I think robots are worth developing because they can do much more than we imagine. And I don’t think they will bring us trouble since they are made by people. We just need to use them in a proper way.
