I want to invent an environmental robot. It can help us sort rubbish. The city is too polluted now. If we want to protect the environment, we need to start from the small things around us. It is everyone's responsibility to sort rubbish. This robot can help us to introduce a lot of garbage classification work. In this way, urban waste can be better managed. Only when the environment is better, our life will be better.

我想要发明一个环保机器人。它可以帮我们进行垃圾分类。现在城市污染太严重了。我们要保护环境的话，需要从身边的小事做起。垃圾分类，人人有责。这个机器人可以帮我们介绍很多垃圾分类的工作。这样可以更好地管理这些城市垃圾。只有环境变好了，我们的生活才会更美好。
