ModuleNotFoundError: No module named 'ardrone_joy' 是指在运行代码时找不到名为'ardrone_joy'的模块。可能的原因是您没有正确安装或导入该模块。要解决此问题,您可以按照以下步骤操作:
1. 确保您已正确安装了'ardrone_joy'模块。您可以使用pip命令来安装该模块,例如:pip install ardrone_joy。如果您已经安装了该模块,请确保版本与您正在使用的代码兼容。
2. 检查您的代码中是否正确导入了'ardrone_joy'模块。请确认import语句是否正确拼写,并且该模块是否在您的Python环境中可用。
3. 如果您已经按照上述步骤检查并仍然出现问题,请尝试重新安装'ardrone_joy'模块。您可以卸载模块并重新安装,以确保安装过程正确无误。
4. 如果问题仍然存在,请检查您的Python环境和依赖项是否正确配置。确保您的Python版本与所需模块的兼容,并确保所有依赖项都已正确安装。

这个错误提示告诉我们 "coroutine 'Safe_5Gaction' was never awaited",意味着在代码中没有等待 `Safe_5Gaction` 这个协程的执行。要解决这个问题,你需要在调用 `Safe_5Gaction` 的地方使用 `await` 来等待它的执行。
假设你在某个地方调用了 `Safe_5Gaction`,你可以这样修改代码:
```python
await Safe_5Gaction(client, userdata, msg)
```
这样就能解决这个错误了。需要注意的是,你在调用 `Safe_5Gaction` 的地方也需要是一个协程(被 `async` 修饰的函数),或者在协程上下文中调用它。
另外,你还需要注意代码中的其他问题,比如 `PosAttSub` 和 `server` 的定义,以及相关的导入语句等。

这段代码是一个ROS节点,用于读取参数并发布无人机的目标位置。它通过订阅`/odom`话题获取当前无人机的位置信息,然后根据预设的目标点,计算当前位置与目标点之间的距离。当距离小于阈值时,发布下一个目标点作为无人机的目标位置。
在`main`函数中,我们首先初始化ROS节点,并设置参数服务器前缀为`~`。然后创建一个订阅器`odom_sub`,用于接收无人机的位置信息。创建一个发布器`param_goal_pub`,用于发布无人机的目标位置。接着从参数服务器中读取参数,包括目标点的数量`waypoint_num`和每个目标点的坐标。最后,设置循环的频率,并在循环中调用`ros::spinOnce()`来处理ROS的回调函数。
其中,`OdomCallback`是回调函数,用于处理接收到的无人机位置信息。在该函数中,我们首先判断是否已经发布了所有的目标点,如果是,则直接返回。否则,计算当前位置与目标点之间的距离`dist`。如果距离小于设定的阈值(这里设为0.1),则发布下一个目标点作为无人机的目标位置,并将目标点计数加1。
请根据实际需求修改其中的TODO部分,完成发布无人机目标位置的代码。
