2017-04-09 10:26:04 -0500 | answered a question | Issues launching ROS on startup I start my roscore on boot simply by adding this line in "/etc/rc.local" before "exit0": the "> /dev/null" means its logs dont get stored anywhere and "&" at the end means it starts in the background. You cant start roscore in root mode, that's why "su pi -c" is at the start of the command. Replace "/home/pi/YOURWS" with your workspace name and destination. |

2015-08-26 16:19:30 -0500 | answered a question | SLAM not working with XV-11 LIDAR sensor So, I solved the problem on my own at the end. Turns out I just had to play around with the Rviz config to get a proper map. PS. I also documented my work with Neato(http://meetjanez.splet.arnes.si/2015/08/22/neato-xv-11-to-ros-slam/) and made a mini tutorial for anyone still struggling with it. Hope it helps :) |

2015-08-22 15:30:03 -0500 | asked a question | SLAM not working with XV-11 LIDAR sensor I'm trying to run SLAM without odometry. When I launch my neato.launch file, this is the error I get: No transform between frames /map and /base_link available after 20.002637 seconds of waiting. This warning only prints once. Im positive that the sensor works, because I can see the raw data on topic. Is it a problem with the sensor driver or is my config in my .launch files wrong somehow? This is my .../hector_slam-catkin/hector_slam_launch/launch/neato.launch file: This is my .../hector_slam-catkin/hector_mapping/launch/mapping_default.launch file: This is my tf tree: https://drive.google.com/file/d/0B6kX... . . . . . . . -------------------------------------------------------------------SOLUTION----------------------------------------------------------------------------------- EDIT: I found out that I forgot to add the line: in the neato.launch file. Now i see something in rviz: https://drive.google.com/file/d/0B6kX... and the map seems to be rotating ok, but there is no map being added and there is no movement in x,y directions if i move the sensor. Also in terminal I still have the error: (more) |
