Hey everyone, I want to receive distance data from Maxbotix sensors over a MAVROS topic named “/mavros/distance\_sensor/…”. Even if I can read distance data as DISTANCE\_SENSOR from MAVLink Inspector on QGroundControl, I couldn’t see its MAVROS topic on the terminal when I type the command “rostopic list”. How can I solve this issue? Thank you.

The reason is that I should have commented the lines of “distance sensors” and “range finders” on px4\_plugginlists.yaml . The document is supposed to be as below:

plugin\_blacklist:  
#common  
-safety\_area  
#extras  
-image\_pub  
-vibration  
#- distance\_sensor  
#- rangefinder  
-wheel\_odometry

plugin\_whitelist: []  
#- ‘sys\_\*’

Small typo error.  
The file name is  
**px4\_pluginlists.yaml**

in the mavros/mavros/launch
