show fake laserscan messages rviz
I want through this laser scan tutorial to send laser scan message in ROS. And I want to display the laser scan in Rviz. But it failed. The Status of LaserScan become error. Also I want to select fixed frame to "laser_frame", but not exist. But I run rostopic echo /Scan
, I can see the frame_id in each data stream.
Any suggestions, thanks for your help.
