thank you for you folks' answer!

I am using ros indigo, working with a MIDG II GPS/INS sensor using this python wrapper, I am able to produce a IMU message, but where is the magnetometer data?

How would I get magnetometer data if I need it?

2018-08-07 21:38:19 -0500 marked best answer For frame [laser]: Frame [laser] does not exist

I am running ubuntu 14.4 indigo. I downloaded this line extraction packet.. I then roslaunch husky_gazebo husky_playpen.launch and roslaunch husky_viz view_robot.launch to start a husky simulation. Then, I followed the line extraction package instruction and started roslaunch example.launch. I checked that both /line_segments and /line_markers are giving me outputs by rostopic echo. Now, I am trying to make the line marker show up on rivz, but I am running into the following error when I added the marker For frame [laser]: Frame [laser] does not exist a picture is shown below: image description

anyone have suggestions on this? thank you.

2018-07-01 16:01:35 -0500 marked best answer modify sick lidar parameters on husky_gazebo

I am using ubuntu 14.04 Indigo. I am trying to figure out the best way to add a hokuyo lidar to the husky in gazebo world. So far, from the husky move base demo ( roslaunch husky_gazebo husky_empty_world.launch), It already has a sick_lms1xx laser on it.

Since, I need to mount the hokuyo lidar on the husky for my simulation, I was thinking of just modifying husky_description/urdf/husky.urdf.xacro from this github source, and change the sick_lms1xx laser configuration such as min, max, increment angles to match hokuyo lidar configuration. However, I can't find all these parameters. Dose anyone know how I can modify them?
