Revision history [back]

It seems not to be a ROS specific question but a LIDAR specific question. nan means mostly the LIDAR didn't received the his laser-ray. The most reasonable answer is "out of range". It could also have other reasons like bright light as noise or "bad" surfaces that don't reflect the ray back to the LIDAR. At your place I would search the answer to your question in first point by the LIDAR. I guess it's a measuring issue.
