i can successfully run the command
roslaunch rplidar_ros rplidar.launch
then i found i cannot found the topic scan created by rplidar_node,but a topic named base_scan created by rplidar_node. what can i do to let the topic base_scan back to scan?
Have you changed the launch file / rplidar_node? It's normally set to publish on scan.
You can remap the topics with the tag <remap> in your launch file :
<remap from="base_scan" to="scan"/>

you can also edit the rplidar.launch file to change the topic name to suit your need.
@chrissunny94 It's not a good idea to edit other packages' source (including launch files). If/when the package is updated then the modified source is gone. @Delb's answer is correct, modify your own source, which is under your control.
