How to change Hokuyo min and max angle values?

Hello everyone,

I have 40 Hz lidar Hokuyo UST-10LX and using in a custom robot. I successfully built a map using gmapping and amcl worked perfectly with this lidar.

My problem is about lidar configuration: Although I successfully used my lidar in amcl or gmapping, when I tried to set parameters using

param name="min_ang" type="double" value="-1.047"

param name="max_ang" type="double" value="1.047"

It seems it does not work. since After changed max and min angle values from above and I opened laser beams in rviz I still see same coverage in laser beams (i.e. Max and min angle DOESN'T CHANGE).

My Hokuyo launch file is as follows:

<!-- Set the port to connect to here -->

How can I change the max and min angle values of Hokuyo 10 LX? Thanks..

According to the documentation the names of the parameters are angle_min and angle_max.

Thank you, I had directly used min_ang and max_ang by just looking the beginning of the documentation, but after your notice I discovered the true parameter name in middle of doc. I tried angle_min and max and now it works!

Thanks...

Shashank_Rao: run rosrun rqt_reconfigure rqt_reconfigure opens a GUI to adjust the parameters.. If you wanna use the command line , use the rosparam command-line tool rosparam. Thanks

Thanks i solved it by changing the params in the .gazebo file of my robot so i guess that works as well
