Easy SLAM with ROS using slam

Easy SLAM with ROS using slam_toolbox

День тому

UPDATE: If you're on humble or newer, please note that "params_file" has changed to "slam_params_file".
SLAM is an important process, underpinning the autonomous behaviour of many mobile robots. The amazing slam_toolbox package for ROS makes getting started with SLAM incredibly simple!

For those having problems loading map. The "params_file" parameter has been changed to "slam_params_file". Hope this help :) Edit: I'm using ros2 humble

@ArticulatedRobotics 8 місяців тому

Good pickup - yes it is changed in humble, annoyingly I missed this when I did my "differences for humble" video and it has cropped up a few times since. Perhaps I will update the description of this video :)

Did not watch this video in particular but all your videos are structured always fine. Highly appreciated that you provide this content for us. There is no other content creator that explains the usage of ROS2 better than your channel. Keep up the good work! we need this.

@ricardocasimiro6424 Рік тому

great job! thanks for the video. it could be interesting to compare with cartographer and also add imu and gps also it could be very interesting to show the base math behind these algorithms

Thanks alot! Very insightful video! Looking forward to the next one too.

@benoitlagassedelocht1595 Рік тому

Finally an updated tutorial series about ROS 2 that is simple, yet very detailed! This will be very helpfull for my next project. keep up the amazing work🦾

@usimian Рік тому

Great video! I've built pretty much the same thing but with a Jetson Nano. I used the same lidar and differential wheel odometry plus an IMU thru the robot_localization package. What I'd like to learn is how to integrate a pointcloud device (I have a sparkfun VL53L5CX) or use two cameras to do visual slam. I agree, slam_toolbox is quite nice. Thanks!

@MartinBgelund Рік тому

Thanks for a great video! I'd like to see more on SLAM, especially using IMU's and maybe even distance sensors (ultrasound and time-of-flight).

@noahHAyoumentionedme 5 місяців тому

Hey I love your videos, you are so clear and precise. It's great! Would you be willing to do a video on vSLAM? I'm particularly interested in orb-slam monocular and similar single camera SLAM method. Thank you so much again!

@carldraper616 Рік тому

Another great video, had to watch it a few times to digest and implement but wonderful content. I also would love to see how you might go about IMU implementation for fused ODOM data. I have totally rewritten by ROS stack based on the Articubot code you provided us. Super well structured and things run so much better so far!

@ArticulatedRobotics Рік тому

Thanks Carl, and having seen your robot I'm very impressed! Re IMU I am also keen to explore that, I've not done it in ROS before but it is a very handy thing to be able to add to a robot.

@nathang4661 9 місяців тому

Thanks for the great video ! Has anyone faced a situation where the odometry and scan topics were not synchronised ? I think it is causing my /scan messages to be dropped so I can't get a map using slam_toolbox.

@alfonsopanadero 9 місяців тому

Hello Josh, At the beginning of July I found your videos, a little late right jejeje. The truth is that you explain it very well and detailed. I've been learning something about ROS1 for a long time. Today I know more with your perfect videos and explanations. Today I have everything working until this video. For which I am very grateful for your effort. Thank you. Note: If someone wants to use more powerful motors, they can use the BTS7960 motor controller that can be directly replaced by the L298.

@ArticulatedRobotics 9 місяців тому

Thanks for your nice feedback! And yes one day I would like to cover the BTS7960. I have used them in the past and found them to be much better though more expensive.

I can't understand from Localization with slam toolbox and Localization with amcl . Could you make a video to explain more about these two points? Or show me how to load the saved map into the rviz.

@hamidhussain5488 6 місяців тому

Thank you for the awesome video! As a newcomer to robotics, I'm eager to work with Gazebo and ROS, and I'll need to use a Windows system with Linux. Could you please provide some guidance on the system specifications that would be sufficient for this?

@MrPrinzovdarkness Рік тому

I would like more videos on SLAM with other sensors as well as how to fuse these sensors and algorithms together

@abelgeorge4953 Рік тому

Hello! Do you think using a imu sensor with a sensor fusion algorithm might help improve the accuracy? Especially when the odometery is not very accurate? If yes how might i go about implementing that with the slam toolbox or nav?

Thanks for your video! Can you help me please to fix one problem with map in Rviz? Ubuntu 22.04 ROS2 Humble. When I run map_server there are no map frame in Rviz: Frame [map] does not exist. But map_server don't have any errors or warnings in terminal afret bringup. Static tf publisher fix this issue, but I don't know how to configure it. I tried to add static tf publisher to map, so map frame appears in Rviz, but if I add static tf from odom to map, both map and odom start stay at the same place when I move robot. It looks wrong...

Hey man, great video as always though I've got one issue with this one, I've tried doing everything exactly the way you do but when I save my Map it does not open again for some reason. I save it, it saves properly but opening it again does not work, I've been at this for 2 days eh...

If you are using humble the command that opens Slam needs "params_file" changed to "slam_params_file" instead.

I have a doubt regarding the project. I've noticed that you controlling your real robot (robot_ws) using developer machine (dev_ws). I am unable interface/control the real robot from my developer machine (dev_ws) to real robot (robot_ws). I kindly request you to share your insights regarding this Thanks in advance.
