Is there anyone who use LMS400 laser scan system, I want to hown how to detemine the zero point of LMS400, which userguide of LMS400 does not show clearly.

In the sicktoolbox tutorials(www.ros.org/wiki/sicktoolbox_wrapper/Tutorials/UsingTheSicklms), It only show us how to get LaserScan Message by serial port, but how can I kown how to use SICK through network.

Ok, finally, I find I use a wrong simulation time, as the clock section said, we should set /use_sim_time to true before we run the service calling node.

I find that the original code exits a bug: in the construction function, the code of the example in the link I list before doesn't include initialization code of ros::nodehandle, I add this code and it works.

I am using single scan sensor_msgs/LaserScan message provided in laser.bag, and I try to use the Laser Scan Assembler to form a bigger point cloud, by it fails in rviz (seems not bring in sensor_msgs/PointCloud message). what are the possible reasons?

Thanks, but sometimes when I use the search engine, these has no results which may due to bad internet or something else. Is it normal when you use the Ros's wiki search engine.

What shold I do if I don't kown some ros code means? Is there something like msdn in visual studio?

For example: I don't quite understand the code below means? what should I do? ros::service::waitForService("build_cloud");
