ROS camera sensor and understanding its properties

[@shozababidi8736]

As a robotics engineering student myself I just want to say that your lectures are amazing. Please keep making more tutorials. 👍

[@robotisim]

Thank you, InshaAllah will do

[@unutnguyen9129]

lmao I struggled for 2 days to successfully simulate it and then I saw this video, the detailed tutorial video is exactly what I did. If only I saw the video sooner, it would have only taken 30 minutes :)) anyway, thank you very much, very good video !!!

[@robotisim]

Great to hear!

[@manavt2000]

Amazing! Waiting for your next videos in this series of ROS wiki...i hope we will get to see more videos in future

[@robotisim]

Very soon!

[@zakiarasheed139]

You explanations are simple and wonderful. Can you also make videos on visual odometery ?

[@robotisim]

Thank you. It was added to the list. hope I complete the list afap :)

[@zainabsaleem4913]

Your videos are good, very detailed and on the point. If you have some experience in using Isaac-Sim with ROS, please make some videos on that too.

[@robotisim]

Yes mam . They are on the list -> running on AWS

4:13 when i see rostopic info /camera/rgb/image_raw it do not tells me that riviz is subscribing. (While i am already viewing stream on rviz). Strange.

[@robotisim]

In rviz change topic of image to your /camera/rgb/image_raw

[@sulaiman-hd8pz]

Was a tutorial on depth camera made already? From what I understand we can simply just change the camera type = "depth" to make the camera able to view the topic /points ? My issue with this is that there is some kind of transform that it is empty

[@robotisim]

Yes and install gazebo plugins pkg

[@waseemsajjad5174]

Camera plugins is not publishing any topics. How I will solve this issue. I tried gazebo tutorials where we have to lahnch two file one for gazebo and other for rviz, and it was working, but when I try to use the camera plugins on simple robot (similar to your previous tutorial)..it does not publish any topic. I tried same to same as did in this video but it was also not working. Am I missing something? Help me sir.

[@waseemsajjad5174]

Now its working becuase at that time, I have not installed ros--gazebo-ros-pkgs ros--gazebo-msgs ros--gazebo-plugins ros--gazebo-ros-control

[@robotisim]

Dependencies missing

[@autominyteam]

Hey there, I'succesfully completed your course, in Udemy for self driving vehicles, so far all is good, however Im wondering if there's any chance you could do a video explaining how to transform the data from the camera lane detection algorithm so it can of example be use to compare its steering with odometer or IMU, working on a PID controller and this would be awesome, any thoughts of adding this into your course or as a video, as there is none existing information. And when I compare the yaw of the odom with the angle from the algorithm does not work as they are not into the same reference frame :C Really guys do apretiatate any help from you and you're doing one of the best courses out there for self navigation in ROS

[@robotisim]

Thanks we are going to update that course , will keep in mind about that.

[@mazmazbiasa]

is it possible to use this camera plugin in drone gazebo simulation?

[@robotisim]

Yes just add in urdf

[@duykhang0709]

i can not run the file roslaunch turtlebot3_gazebo turtlebot3_empty_world . launch . Can you help me?

[@robotisim]

install turtlebot3_gazebo package
