将超声波加入局部costmap时报错，执行以下命令成功解除错误。

# 本人ros版本为melodic，请改为与自己对应的版本。
sudo apt-get install ros-melodic-range-sensor-layer

服务器出现了异常关机，导致容器启动时出现这个错误：Error starting daemon: layer does not exist，反复检查了docker运行是正常的，最后查找了一下docker挂载的数据，于是将docker挂载的数据清空，再重新运行容器。有数据丢失风险，慎重。............

我仿真实验用的车子底盘是阿克曼四轮驱动（前轮转向），试验过程中发现使用DWB 控制器无法进行转弯（按下图），而且很容易提前停止，然后想尝试TEB 控制器，发现 navigation2 已经不支持（teb_controller 不适用 ros2 的问题），说是已经整合到MPPI 控制器了，所以有了这篇文章的尝试。项目Value系统ros2版本humble建图方案底盘驱动Navigation2 导航插件。

针对导出dxf文件时点击lib按钮列表conversion文件为空的情况，主要问题是环境变量env加载的问题，在candec安装目录（例如c:\cadence）下创建pcbenv文件夹，将c:\cadence\spb_16.0\share\pcb\text中的env文件拷贝到C:\Cadence\pcbenv中，重启软件即可。据说还可以修改env进行快捷键自由编辑。

机器人导航过程中，有两个问题 1.在行进过程中，当扫描到动态障碍后，将障碍记录到地图信息中，如果这块区域不再扫描到，则这块动态障碍区域永远不再消失。如果指定目的地为这块区域时，算法会显示该地方不可到达 2.很多人围着机器人，地图中会出现很多动态障碍，当人群散开不再围着机器人时，costmap中会残留很多动态障碍，并且长时间不消失。通常来说是扫描范围中最左边和最右边的区域里动态障碍不会消失，怀疑

记录学习阅读ROS Navigation源码的理解，本文为Costmap2D代价地图源码学习记录，以文字总结、绘制结构图说明、代码注释为主。仍在学习过程中，有错误欢迎指正，共同进步。障碍层地图通过订阅传感器话题，将传感器输出的障碍物信息存进buffer（剔除过高、过远的点），在本层地图上将观测到的点云标记为障碍物，将传感器到点云点连线上的点标记为FREE_SPACE。最后，在bound范围内，将本层地图合并到主地图上。
