Hi, nice tutorial. It realy helped me to get start with the RPLidar. A thing I noted when you explained the changes in the "tutorial_tif.launch". You had show a change in the line 8, but there is a change in line 13 too. You had to change the old name "mapping_default.launch" to the filename you created "mapping_tif.launch". It was in the minute 8:05, it already has the new filename. I did it here and worked very well. Thanks for the excelent video

First of all thank you for these amazing videos which helped me a lot! I have a similar project right now: I want to install the RPLIDAR A1 on a little car and connect it with a raspberry pi 3. I want to start the scan from my laptop and visualize the map with Rviz. So i use this order of steps: - start roscore on my laptop - tell pi that the laptop is the master (export ROS_MASTER_URI=) - define my pi as a talker and laptop as listener (rosrun rospy_tutorials talker.py) - start Rplidar - than i type "rosrun tf static_transform_publisher 0 0 0 0 0 0 map scanmatcher_frame 10" I did this because I was getting the warning "No transform between frames /map and scanmatcher_frame available after 20.002338 seconds of waiting. This warning only prints once." - start hector slam. When i start hector slam, Rviz opens but the map is empty and the terminal gives me the following info: "lookupTransform base_frame to laser timed out. Could not transform laser scan into base_frame.". Do you know what i'm doing wrong because when i connect the Lidar directly to my laptop everything works fine as in your video. I sourced after every new shell and i also used everytime the "export ROS_MASTER_URI"-command. Greetings

But this time hector slam will not be used for mapping, it will just provide the odometry data which in turn will be fed into the amcl module.

Great tutorial ! I'm trying your program on an Odroid XU4 ...the solution works very well until I turn the rplidar A1 on the Z axis. The detection is affected and the map also starts to turn in the same direction.
@prandtlmayer4 жыл бұрын
yes, turning is something he doesn't like. try to keep the unit absolutely flat and rotate slowly

Hi, nice video bro! But i have a problem, my rplidar A1 is not scanning, when i follow your instructions on windows it doesn't show me the distance information, it is just displaying the 360 degrees picture on the frame grabber, my lidar is spinning but the grabber says it is 0 Hz (0 rpn)
