I enjoyed making the video. Looking forward for more tutorials

Thanks for the video. I bought the RPlidar A1 recently and was able to make a map of my room successfully.

This is incredible. The fact that you can get this software for free is even more awesome.

Great tutorial, I almost slept reading through the ROS wiki. Videos are so easy to understand. Looking foward to a tutorial for autonomous navigation with slam on rasperry pi.

Many thanks. I´m a civil engineer and was able to do the same with RPLidar A3, the results are much better with this model. Now to export to CAD file :P

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

Thank you for such a valuable video!! We will keep learning, please dont stop posting.

Hi! It's important to say that if you rotate the Lidar fastly in one axis -- you can have problems for mapping, occasionally it's happens when you have a diff drive robot. Great video!

You are a blessing! Beautifully explained and to the point.

Exactly what I was looking for! Thanks

Kindly make part 2 of it. SLAM

Love your shirts, your video, and definitely your project!!!

Thanks a lot i was looking for this. Excellent explanations. Looking forward to navigation go to goal and how to integrate same with ROS arduino motor control to move robot. God bless you. Regards

Thanks a ton. This way really worked.

I was followed your this tutorial for build the map using same sensor as you used, but then when i started hector_slam my map wont generate correctly as i move the lidar in diferent position the obstacle change position to, can u help me?

could you explain why you set the parameter to zero at 7:53, what if lidar is not place at centre. do i have to change it accordingly?

Can u use the slam for 3d lidar lslidar? Im working on project AMR but still confused with the 3d slam

This video is all my needs :3 thank you

Please help me ERROR: cannot launch node of type [hector_mapping/hector_mapping]: can't locate node [hector_mapping] in package [hector_mapping]

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

Whenever I start the hector map, there will be an error of "cannot launch node of type [hector_mapping/hector_mapping]: can't locate node" along with [hector_trajectory_server] , [hector_geotiff] as well, is there any fix for this?

Thank you so much! This helped a lot.

Hello sir I successfully created map using hector slam now i want to localise my robot in that created map only using laser scan and hector slam can guide me how can i do that?

Please help me ERROR: cannot launch node of type [hector_mapping/hector_mapping]: can't locate node [hector_mapping] in package [hector_mapping] What shall i do ? :(

Hello, I would like to ask if this method work also with rplidr c1 .. please help me 🙏🏻🙏🏻

Awesome as always! Thank you!

I really didn't understand how to install the Lidar program on ubuntu.... I went on the link... but still too confusing

When I wrote "ls /dev/ttyUSB0", it says there is "no such file or directory". What should I do?

I made a mistake in "lookupTransform base_footprint to laser timed out. Could not transform laser scan into base_frame. " when ran the command line roslaunch hector_slam_launch tutorial_tif.launch. May you give me a piece of advice to fix this error?please

why did not my rviz show anything when I run the command line "roslaunch hector_slam_launch tutorial_tif.launch"?

Very useful tutorial, thank you. Could you please make a tutorial on how to integrate Hector slam with amcl location. Many thanks.

I`m new in ros, and i try to do this tutorial using a X2ydlidar, but when i launch the tutorial file i see this en rviz " Fixed Frame [map] does not exist " and the program doesn`t work . What can i do to fix it ? th

Hii Can you please help on navigation using the saved map in map server by hector slam, need your help ! Thanks a lot. Best wishes

I'm getting an error that says "Fixed Frame[map] does not exist" With the message saying "No map received". What should i do?? Also, the terminal is saying cannot locate node of type hector_mapping in package hecktor_mapping.

hello sir, when I click scan, my rplidar A1M1 is spinning but showing 0.0 Hz (0 RPM) on frame_grabber. Do you know what the problem might be? It takes me weeks now and I haven't found any solution yet.

@Tiziano Fiorenzani I have followed your tutorial for the setup of the RPLidar A1, but when I type "roslaunch rplidar_ros view_rplidar.launch" onto the terminal I get an error message saying that scan mode "sensitivity" is not supported by the lidar. I have done some investigating into the matter and one of the suggestions was to edit the launch file, however the view_rplidar.launch file does not contain lines regarding the scan mode. Because of the error the rviz gui does not show anything. Any help would be greatly appreciated.

Hello, I am using it on my ros robot, I followed the all steps, but it says For frame [laser_frame]: Fixed Frame [map] does not exist

great video thanks. keep it coming !

Hello sir, in 7:50 I cloned file mapping_tif.launch and file tutorial_tif.launch, but after I catkin_make, 2 new files aren't generated. Please help me, thank you sir !

please help i am geting error ls: cannot access '/dev/ttyUSB0': No such file or directory i using slamtec lidar m2m1

Sir, Please upload a video with path planning and obstacle avoiding using lidar sensor.

Hi Tiziano. Thank you for the video. Unfortunately when I follow the steps the output in my terminal reads ‘lookupTransform base_link to laser timed out. Could not transform laser scan into base_frame.’ Do you know how I could fix this problem? Thank you

Thanks for the great video!! Quick question - can you use this for 3D SLAM -- say mount the RPLIDAR on a plate (on top of a drone), connected to motor shaft that bobs between 45 and 315 degrees to produce a 3D map of its environment?

thx for this great tutorial!

Hi Tiziano Fiorenzani, may I know where did you get the Framegrabber application? The one i am currently using is always showing "Unable to bind to port" even though i selected the correct port based from the Device Manager setting

Does anyone know why after installing the drivers, there is no port found in the ports section in device manager?

Hello Tiziano. Excellent tutorial!!! I have seen a few of your videos, and love them. Can you please do one where you go into odometry?

My rviz gives a strange error from this, that the fixed frame map does not exist, do you have any clue why? I followed the steps with hector slam, but the rplidar was preinstalled on my pi

Did ever have an error that said " Can not start scan: 80008000!"? Help please.

Hi, is there a ready kit available for mapping indoor spaces?

Hey. I have a doubt. I need to get the lidar position values from hector slam.When I run the tutorial.launch file, I see a topic called "slam_out_pose" which publishes these values, but I can't seem to figure out how to write a subscriber for it. Could you help me out here? Thanks.

This is very nice, thanks for sharing. I have a question, the RPLIDAR can be used to make a 3D model if using it a vertical position while walking in a hall, and if its posible, can be done with HectorSlam?

How can i move my robot in rviz. Help me

Amazing video! where is the donate button - one question how can we export the map to point cloud data .PCD because i want to use it in Autocad to generate an accurate floor plan.

I am on a mac running virtual box (ubuntu latest) and am having trouble with the 'sudo chmod 666 /dev/ttyUSB0', it saying the file or path does not exist. Does it matter to which of the 4 USB-C ports on my mac i plug my lidar to? when i roslaunch rplidar_ros package, the rviz does not show my lidar scan. please send help!

Hi there, very good video, thank you! I used it sometime ago. But now, I'm working on a humanoid /biped. Does the same thing apply or should I leave it as it was before your editing? Thank you in advance.

Thanks for your explanations I found it very useful but I have some problems when I download the hector slam file I can not find the tutorial tif launch file please I need help thank you for your help

Could you do a video of putting the RPLidar on a servo to allow 3D mapping? Thanks

Please help me , when catkin_make im ocurred this error CMake Error at /usr/share/cmake-3.10/Modules/FindQt4.cmake:1320 (message): Found unsuitable Qt version "" from NOTFOUND, this code requires Qt 4.x Call Stack (most recent call first): RPLidar_Hector_SLAM/hector_slam/hector_geotiff/CMakeLists.txt:12 (find_package)

So....how to do navigation after this? I can save the map. But still don't know what to do next.

So good

Hi and thanks for ur video, well explained, do u have an idea where to add the IMU datas to fuse with hectorslam and get better orientation estimations ?

hey thanks for the great video. Have you done the same SLAM with the lidar lite v3?

hii @tiziano amazing work but i hv a query , i can run the slam with a bag file but not in real time what shall i do?

how can I use Scan_matching with this HECtor-slam pakage bro???

Hi, I tried this tutorial and it worked correctly, but when I try to re-run the statement: RLException: [view_rplidar-launch] is neither a launch file in package [rplidar_ros] nor is [rplidar_ros] a launch file name The traceback for the exception was written to the log file roslaunch rplidar_ros rplidar.launch from catkin_ws I get the following error: RLException: [view_rplidar-launch] is not a launch file in the [rplidar_ros] package nor is [rplidar_ros] a launch filename. The exception trace has been written to the log file. What can I do?

Plz ...make tutorial to control dynamixel servo motor.....or suggest best platform for learning it .......

what is the application you run after installing the driver? It just seems to be pull out of no-where and I can't find it... Thanks!

from hector slam can i get the data by which it creates the room floorplan? here in your picture i can see the black dots which represents the wall. From hector slam can i get the value which represent these black dots? I am planning to detect the corner, is there any way that i could detect the corner?

Thanks Tiziano for sharing the knowledge. I wonder how the SLAM points can be geotag for outdoor mapping then the data be integrate into GIS software.

Dude you are amazing seriously. Why don't you make it a course and teach on udemy/edx platforms?

in the last part i just recive this msg RLException: [tutorial_tif.launch] is neither a launch file in package [hector_slam_launch] nor is [hector_slam_launch] a launch file name The traceback for the exception was written to the log file

2:22 I did find the driver in ny device manager but when I double click on it, it goes to "properties". I dont know how to reach the mapping interface. Please help

Please help me [tutorial_tif.launch] is neither a launch file in package [hector_slam_launch] nor is [hector_slam_launch] a launch file name The traceback for the exception was written to the log file

please help me : when i run rviz it error : segmentation fault (core dumped) how i can fix it, install ubuntu 18.04 (not ubuntu mate) and ros melodic and vnc viewer to monitor. is it ok? and now how to fix this problem ???

Sir i m new to Slam and doing hector slam using raspberry Pi 3 with utiquity robotics Ubuntu ros ..but unfortunately I got the this error can anyone help me??

Hi Tiziano, do you have a similar video for the RPLIDAR S1?I would be grateful,if you could tell me a good source I could follow for that module.

Hi, I've followed the tutorial through to running the hector slam launch file, but i'm getting an error reading as: Invalid tag: hector_geotiff ROS path [0]=/opt/ros/kinetic/share/ros ROS path [1]=/opt/ros/kinetic/share. Arg xml is The traceback for the exception was written to the log file if it helps when I typed the grep ttyUSB line all that was returned was 'ttyUSB0' I'm new to the subject and any advice as to my error would be appreciated, thanks.

Good Video, Currently I'm working with a RPLidar A2, but I couldn't open the frame grabber aplicattion. Could you help me?

Hello, do you have an advice, if the device manager is not showing this required port ? Thanks very much in advance !

Thank you so much for this. I was stuck with my own set up (I need to get more familiar with tf). This really helped me. Thanks!

Hi! I really like this video! It's very helpful!! I was wondering if you happen to know how to configure the scan frequency of the RPLidar? I saw in the Slamtec website that it can be up to 10Hz. However, I can't find out how to configure it. Thanks!

how to interface hector slam and rplidar with values in raspberrypi. please help me to get out of this sir

Awesome video as always. Thank you I want know if i can implement these packages with tf mini lidar ?

hi i am trying to do this with rpi and pc. i have tried to attached the lidar to the rpi and was able to see the /scan topic from rpi to pc but when i run rviz on my PC there's an error for the /tf "No tf data. Actual error: Fixed Frame [map] does not exist" please help me im doing this for my thesis

Hi, that was useful, so this instructions can work in order tu use RPLIDAR A3M1? Im still without making it move

A very good and precise tutorial! I have a question though: Which one will be better Gmapping or Hector Slam for indoor navigation a differential wheeled robot?

Great Video Thanks... Question, I am using the same model RPlidar as you are but get a " started core service [/rosout] process[rplidarNode-2]: started with pid [6604] process[rviz-3]: started with pid [6605] [ INFO] [1591737781.112395048]: RPLIDAR running on ROS package rplidar_ros. SDK Version:1.12.0 [ERROR] [1591737783.970103291]: Error, operation time out. RESULT_OPERATION_TIMEOUT!" after running roslaunch command. Do you thing its a RPLIDAR problem? I checked the USB permission etc already.

Great video :)

great tutorial! is it possible that we could integrate this with an RPLIDAR A2 and add our own pathfinding algorithm with it?

hi, if I want to run roslaunch rplidar_ros at standard mode, then how can I do so?

how can i find catkin_ws file?

My Global Status provides a warning statement, stating that there 'Fixed Frame' has no TF data; Actual Error: Fixed Frame [laser] does not exist. Anybody knows how to resolve this?

Hi! I want to know which raspberry pi were you using for this, and also which version of ubuntu pls

@Tiziano Fiorenzani - Nice video tutorial. What part of the software runs on Raspberry Pi and what part runs on Ubuntu laptop?

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.

Thank you for the video this was very helpful .I am looking for help in making an atonomus robot so if have anything about how to make a atonomus robot using pi and slam please upload it fast. I am very much curious to learn about it. Thank you

How can I prevent a broken map? I'm using rplidar A1 and the setting showed in this video, Thanks so much

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)

Can you tilt this and do a full 3d maping? or just 2d? Really interesting
