1. 减少 source 到 bashrc 中

为了不必在小车的 Ubuntu 上每次都 source 本人的工作空间，我把本人的 workspace 加到 ~/.bashrc 文件开端：

而后重启 shell，之后就会主动 source 我得工作空间，能够应用 roscd 间接进入指定包中：

roscd pkg_name

2. 编写启动 launch

每次调试小车，都要别离启动很多节点，比方交融、建图、Loam、Rviz 等，所以我把这些节点全副配置在一个 launch 中启动，间接一行命令启动，这样调试就不便多了，大大节省时间：

  • lidar_camera_fusion\launch：lidar_camera_fusion.launch
  • octomap_server\rviz：octomap_debug.rviz
  • octomap_server\launch：dlonng_octomap_test.launch
<launch>  <!-- Start ZED! -->  <include file = "$(find zed_cpu_ros)/launch/zed_cpu_ros.launch" />  <!-- Start Robosense LIDAR! -->  <include file = "$(find rslidar_pointcloud)/launch/rs_lidar_16.launch" />  <!-- Start fusion node! -->  <include file = "$(find lidar_camera_fusion)/launch/lidar_camera_fusion.launch" />  <!-- Start Octomap node! -->  <include file = "$(find octomap_server)/launch/octomap_server_start.launch" />  <!-- Start octomap_debug.rviz -->  <node pkg = "rviz" type = "rviz" name = "$(anon rviz)" respawn = "false" output = "screen" args = "-d $(find octomap_server)/rviz/octomap_debug.rviz"/>  <!-- Start Lego Loam! -->  <include file = "$(find lego_loam)/launch/demo.launch" />  <!-- Only using in map build test! -->  <node pkg = "tf2_ros" type = "static_transform_publisher" name = "dlonng_static_test_broadcaster" args = "0 0 0 0 0 0 base_link rslidar" /></launch>

3. 补充一些小 Tips

如果不晓得要启动的包的 launch 文件叫啥，能够查找指定包的门路，而后进入看看 launch 文件夹上面的启动文件叫啥：

rospack list | grep "zed_cpu_ros"
rospack list | grep "rslidar_pointcloud"

之后我就能够从 octomap_server 中一键启动所有我建图要用的节点了：

roslaunch octomap_server dlonng_octomap_test.launch

然而启动过程中遇到 rviz 节点名字反复的问题，我把雷达启动的 RVIZ 关掉或者把启动 RVIZ 的节点名称扭转下，避免反复。
