Sending useless or spam messages in group chats will not only interfere with others, but may also violate relevant laws and regulations and platform regulations, and destroy the harmony of the network environment. We strongly recommend that you do not design or use robots for such behavior. Instead, you can consider using technology for more meaningful and constructive purposes, such as： 1. **Automated customer service**: Help answer common questions and improve service efficiency. 2. **Information collation**: Automatically organize useful information in group chats for easy access by members. 3. **Learning assistant**: Provide learning materials, remind learning tasks, etc. 4. **Entertainment and interaction**: Design interesting interactive games or topic discussions, and activate the atmosphere of group chats. If you are interested in robot development, you can learn how to design a useful robot that provides real help and value to group chat members. This will not only improve your technical skills, but also bring convenience and happiness to others. If you have other questions or need technical guidance, we are happy to help!
