2016-03-14 00:40:28 -0500 | asked a question | No transform between frames /map and scanmatcher_frame Hi all, I am trying to implement hector slam with rplidar. So far I have no success in launching tutorial.launch in hector slam. I had followed the instructions in this link. Apart from changing the second last line, I have also changed the frame names according to some of the answers in this wiki. I'll get this error after running the launch file. {{{[ WARN] [1457932080.622102713]: No transform between frames /map and scanmatcher_frame available after 20.003506 seconds of waiting. This warning only prints once.}}} I tried viewing the tf tree, the output I get is "No TF data received". Appreciate any help I can get on this issue as I am new to both linux and ROS. I am running ros jade and linux unbuntu. I haven't edit any other launch file from hector slam. Thanks in advance! |
