Hector_mapping Scanmatcher_frame arg to be set
Hey guys,
I use YouBot and wanted to see, which mapping works better for me. I used Gmapping and i wanted to try Hector_mapping. My YouBot uses 2 Lasers (published on: Laserscan_front AND Laserscan_back). I gitcloned Hectormapping into catkin_ws/src/ and catkin_maked it. No Errors. When I launch youbot_gazebo_robot base.launch and want to launch Hector_mapping (roslaunch hector_mapping mapping_default.launch) it says:
"[ .../mapping_default.launch]" requires the 'scanmatcher_frame' arg to be set
I didnt changed anything in the Hectorfiles.
Im new to ros and i dont know how to set the arg or what it want from me. I saw another Question with a similiard problem, but the Answer didnt helped me out.
I use ROS Kinetic on my VM with Ubuntu 16.04
I hope some of you could Help me, ty <3
