Turtlebot3 Rviz使用多个路径发射
大家好，所以我试图启动turtlebot3_gazebo_rviz，但我遇到了这个错误。
roslaunch turtlebot3_gazebo turtlebot3_gazebo_rviz.launch
... logging to /home/zac1405/.ros/log/78418374-e1c4-11ec-86d1-000c295c3592/roslaunch-

我怀疑发射器无法选择正确的途径，这就是为什么它会摇动三个不同的路径。我的想法是删除路径0和路径2，并仅使用索引1的路径。我希望我的期望是正确的，否则我希望有人可以帮助我。 先感谢您

I suspect that the launcher was not able to choose the right path to start with, which is why it shakes three different paths. My idea was to remove path 0 and path 2 and use only the path with index 1. I hope my expectation is correct, otherwise I hope someone can help me.
Thank you in advance
