ros杂记

1.找不到自己创建的功能包，有可能是环境变量没有设置

source devel/setup.bash

2.打开文件命令

xdg-open CMakeLists.txt

3.出现这个错误ERROR: cannot launch node of type [robot_state_publisher/state_publisher]: Cannot locate node of type [state_publisher] in package [robot_state_publisher]. Make sure file exists in package path and permission is set to executable (chmod +x)
是launch文件出错，其中的node节点有问题，检查！

type="state_publisher"这里错了，应该是type="robot_state_publisher"

4.rviz中滑动条不出现

joint-state-publisher修改为最新的包joint-state-publisher_gui

roslaunch marm_description view_marm.launch
