Issue with Hokuyo laser scaner
Hi
I am doing Hector SLAM with the hokuyo laser scanner and sometimes when the lens is dirty or comes in contact with dust during flight, the SLAM fails leading to crash I plan to analyse the hokuyo laser scanner path in rviz and if there is any specific way to see the impact of dust on the scanner. Any help will be greatly appreciated
Maybe you can check if there is any false-reading under impact of dust. If you are using urg_node, you can also check the diagnostics topic which show the laser's error if any.
How do I check the diagnostic topic ? Have anybody had similar issues with dust on the laser scanner ?
We used to have problem with dust issue but it mostly affects navigation. Assuming the laser is in a good condition, the mapping should be fine in acceptable-dusty environment.
Are you using urg_node to connect to your laser?
Yes, I am ...
Following this: http://wiki.ros.org/urg_node , the topic name is
diagnostics
Thanks, is there any way to see the error reading in rviz
could you pls guide me on how to print the diagnostic_msgs
