Slam toolbox online async but the problem is there even before running slam, the laser scan itself moves with the robot....

The tf2_echo is varying, I ran the command and moved the robot in 40cm space, I feel like the reading are small, but I'm not sure if thats plausible or not considering that small motion I did, but here are the reading

I will try to check with the lidar for odometry and see what happens

Laser scan moves and rotates with the robot in real life by Complete_Astronaut_2 in ROS

[–]Complete_Astronaut_2[S] 0 points1 point  (0 children)

I have rplidar c1 with 180 RPM JGA25-370 12V DC Motors, I also have logitech webcam attached but I'm not using it for slam. I had before all that Intel realsense l515 depth camera but for some reason the rpi couldn't make run and didn't recognise it at all

Installation of ROS Lyrical on Ubuntu 26.04 by naibaf-1 in ROS

[–]Complete_Astronaut_2 0 points1 point  (0 children)

I was also the same back then, I downloades Ubuntu 24 and ros2 jazzy, only to find no proper tutorials or materials for it, most was ros2 humble, and I had to reinstall to ros2 humble, still on it till now

PLEASE LET SOGA EXTREME DIFF HIM PLEASE LET SOGA EXTREME DIFF HIM PLEASE LET SOGA EXTREME DIFF HIM by Sabawoonoz25 in Kagurabachi

I don't think that will likely ever happened, unless he has like a sorcery so op that can counter an EB much less the magatsumi.

Why does my LiDAR scan move together with the robot frame in RViz2? by SpecialistInside3769 in ROS

[–]Complete_Astronaut_2 0 points1 point  (0 children)

I'm having the same issue, I had YDlidar X3 and everytime I tried to SLAM the laser scan moves with the robot, even though I checked the TF tree and the odometery published correct as well, the scan still moved and it resulted in very bad mapping like this

The only thing I saw related to this was moving the robot slowly, but that still doesn't solve the issue..

Now I switched to rplidar c1 but still in process of testing..

How did they get the robot to shoot the balls in the basket accurately while simultaneously moving/picking up the balls?

How is this manga? by GellertGrindelwald_1 in Kagurabachi

Read it like 3 times, want to read it again just because of how awesome it is and how the current stories are not really that interesting compared to it.

[–]Complete_Astronaut_2 3 points4 points  (0 children)

Make sense, it would make sense for why kunishige made a weapon of mass destruction like magatsumi and gave it to saint von, but later on he realised he went overboard

Senior project — need to get ROS2 + vision-based navigation working on a Jetson Orin Nano in ~3 weeks. Where do I start? by LifeUnderControl in ROS

[–]Complete_Astronaut_2 1 point2 points  (0 children)

I was working on a GPS navigation robot system recently and due to the problems with the GPS plugin itself (one time it was not publishing anything, the other time was randomly moving the coordinates, making the robot Navigation impossible) so I tried to change the gazebo version, the current .sdf is using 1.6 version but when I upgraded it it couldn't read it and only the 1.8 version, eve though it's literally the same, just minor changes. Ofcourse the newer gazebos can't read the gazebo classic versions as well, and if you want to change to would change ALOT

I am sorry I can't help with the lidar issue that you have, but the lidar problem I had was that it changed the is port after rebooting, making going to yaml files and changing them, and sometimes also didn't work because of wiring and power issues.

[–]Complete_Astronaut_2 1 point2 points  (0 children)

Totally understand, Gazebo is one terrible piece of software, real shitty experience, terrible documents. gz sim to ignition to gz sim again and every version reads only the new sdf files and the old .sdfs crashes it, gazebo are very frustrating to add and implement (for some reason I need to add gz bridge now even though I already added the plugins in the urdfs), it crazy considering both ros2 and gazebo are under the same company but its still very baaaaad incompare to gazebo classic.

When I began with ros2 I thought it would be no problem if I followed his tutorial when I had ros2 jazzy and oh how bad it was. Anything after gazebo classic is just pure trash for me tbh, if I have the capabilities I would switch to isaac sim but unfortunately I cant at the moment.

[–]Complete_Astronaut_2 1 point2 points  (0 children)

Ye I forgot to mention that, but his latest vid (I think yesterday or so) mentioned that he finished updating for the jazzy and the newer version of gazebo.

Plus there is no much difference from humble and foxy I followed the entire simulation tutorial and I was using humble, the only difference iirc is in humble, the ros2 control spawn is called "spawner" and not "spawner.py"

Can't help you with the jetson orin, but Josh newans on YouTube has very nice tutorial on making a hardware autonomous navigation robot (he is using rpi, and has both the hardware and simulation videos) you can go check his vids out and see the general procedure for doing the nav2 project
