这些警告信息表明在执行costmap过程中出现了问题。根据警告信息来看,可能是由于没有找到base_link到map的变换关系导致的。请确保在运行costmap之前,确保base_link和map之间的tf变换已经正确设置。你可以通过查看tf的配置文件或者执行tf相关的命令来确认这个问题。另外,还可以尝试增加等待时间来等待tf变换的建立。如果问题仍然存在,请提供更多的详细信息,以便我能够更好地帮助你解决问题。

Failed to complete request: java.lang.NullPointerException
As an AI language model, I don't have enough context to determine the exact cause of the error message you are seeing. However, a `java.lang.NullPointerException` error message usually occurs when your code is trying to access an object or variable that has not been initialized or is null.
To resolve this issue, you can try the following steps:
1. Check your code for any uninitialized or null objects or variables.
2. Make sure that all objects and variables are properly initialized before they are used.
3. Use proper exception handling techniques in your code to catch and handle NullPointerExceptions.
4. Debug your code and check the stack trace to identify the exact line of code where the error occurs.
If you are still having trouble resolving this issue, you may need to seek help from a Java developer or a community forum.
sqlite3.IntegrityError: UNIQUE constraint failed: Content.内容
This error message indicates that there is a unique constraint applied to the "内容" field in the "Content" table of your SQLite database, and that constraint has been violated.
A unique constraint ensures that no two rows in a table have the same value in a particular column. In this case, it seems that you are trying to insert a row with a value in the "内容" field that already exists in another row, and this violates the unique constraint.
To resolve this issue, you need to either remove the unique constraint from the "内容" field or ensure that the value you are trying to insert is unique. You can also update the existing row with the same value instead of inserting a new one.
