]]>http://community.bwbot.org/topic/16654/ros自动驾驶-雷达检测不到求助RSS for NodeSat, 08 Aug 2026 01:26:07 GMTWed, 28 Aug 2024 16:14:56 GMT60<![CDATA[Reply to ROS自动驾驶 雷达检测不到求助 on Thu, 29 Aug 2024 17:35:08 GMT]]>从您提供的日志来看，确实有可能是更新固件（firmware）导致了连接问题。具体来说，cfg getaddrinfo(): Name or service not known 表示系统无法解析激光雷达的主机名，这通常与网络配置有关。而 Licensing: STEER firmware build date: 2023/09/13 显示了固件的构建日期，这表明您的固件版本是最近更新过的。

以下是几个可能的原因和解决方法：

1. 检查网络配置

更新固件后，激光雷达的网络配置可能发生了变化。请确认以下几点：

  • IP 地址：确保激光雷达的 IP 地址没有改变。您可以通过激光雷达的管理界面或命令行工具查询当前的 IP 地址。
  • 主机名：确保激光雷达的主机名没有改变。如果主机名改变了，请相应地更新 /etc/hosts 文件。

2. 更新 /etc/hosts 文件

确保 /etc/hosts 文件中包含正确的条目来解析激光雷达的主机名。您可以按照以下步骤操作：

  1. 打开终端。
  2. 使用文本编辑器编辑 /etc/hosts 文件：
    sudo nano /etc/hosts
  3. 添加或更新以下条目（替换 `` 为实际的 IP 地址）：
     os-122139001039.local
 os-122142001045.local
 os-122128000279.local
  4. 保存并退出编辑器。

3. 检查网络连接

确保您的计算机和激光雷达之间的网络连接正常。您可以尝试以下命令来检查网络连接：

ping os-122139001039.local
ping os-122142001045.local
ping os-122128000279.local

如果无法 ping 通，请检查网络配置或联系网络管理员。

4. 检查激光雷达的固件版本

确保激光雷达的固件版本与您的 ROS 节点兼容。您可以尝试以下步骤来获取激光雷达的固件版本：

  1. 登录激光雷达的管理界面（通常可以通过 Web 浏览器访问）。
  2. 查看固件版本信息。
  3. 确认固件版本与 ROS 节点的兼容性。

5. 检查日志文件

查看具体的日志文件（如 /home/uiuc/.ros/log/254ded82-6553-11ef-93bc-0242e34281bb/front_lidar-driver_node-4.log），可能会提供更多关于问题原因的信息。

6. 重新启动激光雷达

有时候，简单地重新启动激光雷达也可能解决问题。尝试关闭激光雷达电源，等待几分钟后再重新打开。

7. 回滚固件版本

如果以上方法都无法解决问题，您可以考虑回滚到之前的固件版本，看看问题是否解决。您可以联系激光雷达制造商获取旧版本的固件并进行回滚。

希望这些步骤能帮助您解决问题。如果有任何进一步的问题，请随时告诉我。

[ INFO] [1724859343.275541851]: Licensing: STEER firmware build date: 2023/09/13
cfg getaddrinfo(): Name or service not known

这一行，请问是因为update 了firmware才导致了错误吗

]]>http://community.bwbot.org/post/17447http://community.bwbot.org/post/17447Thu, 29 Aug 2024 17:34:16 GMT<![CDATA[Reply to ROS自动驾驶 雷达检测不到求助 on Thu, 29 Aug 2024 03:30:29 GMT]]>根据您提供的日志信息，您遇到的问题主要集中在激光雷达（LiDAR）节点无法正常启动。具体来说，问题包括但不限于：

  • Aravis 相关的断言失败：这表明 Aravis 库（用于与相机设备交互）可能无法正确初始化相机。
  • GStreamer 启动失败：GStreamer 是一个用于流媒体处理的库，它在这里被用来处理来自相机的数据。GStreamer 无法启动可能意味着数据流存在问题。
  • 传感器初始化失败：由于无法解析 IP 地址，导致传感器无法初始化。

解决方案建议

1. 检查 Aravis 库版本和兼容性

确保您的 Aravis 库是最新的，并且与您的操作系统和其他依赖项兼容。您可以尝试更新 Aravis 库并重新编译相关节点。

sudo apt-get update
sudo apt-get install --only-upgrade libaravis-dev

然后重新编译您的项目。

2. 检查相机连接

确保所有相机设备已正确连接并且能够被系统识别。您可以通过 lsusb 命令检查设备是否被系统识别。

3. 检查网络配置

从日志中可以看出，存在 getaddrinfo(): Name or service not known 错误，这表明您的系统无法解析激光雷达的主机名。请检查您的 /etc/hosts 文件是否包含了正确的条目以解析激光雷达的主机名。

编辑 /etc/hosts 文件，添加如下行：

   os-122139001039.local
   os-122142001045.local
   os-122128000279.local

其中 `` 是您激光雷达的实际 IP 地址。

4. 检查激光雷达配置

确保激光雷达的 IP 地址配置正确，并且与您的计算机在同一网络内。您可以使用 ping 命令检查网络连接：

ping os-122139001039.local
ping os-122142001045.local
ping os-122128000279.local

如果无法 ping 通，说明网络连接有问题。

5. 检查日志文件

查看具体的日志文件（如 /home/uiuc/.ros/log/254ded82-6553-11ef-93bc-0242e34281bb/front_lidar-driver_node-4.log），可能会提供更多关于问题原因的信息。

6. 重新启动激光雷达

有时候，简单地重新启动激光雷达也可能解决问题。尝试关闭激光雷达电源，等待几分钟后再重新打开。

希望以上建议能帮助您解决问题。如果您还有其他疑问或需要进一步的帮助，请随时告诉我。
