One of the best explainations for ROS2 Navigation!! Request you to make similar videos for Moveit,Moveit2, PCL, RTAB, Ignition

[@kalucardable]

You speak very fast but your explanations are clear lol. Thank you for helping the community with your videos.

[@jatinpatil1013]

you can use docker to run ros2 humble on jetson nano with any ubuntu version

[@roboticsandroslearning8232]

I didn't know this. Thanks for the information. Will try it out.

[@jwp-yh8wh]

But you can't use usb ports and other ports right?

[@mohitks62]

Glad to see you back

[@betahex3589]

i get package 'nav2_recoveries' not found error

[@ramanabotta6285]

Super anna ❤, waiting for your videos

[@pranavpatil7312]

how to implement the CAN communication to control the motors through the Jetson Nano?

[@roboticsandroslearning8232]

I have not worked on CAN communication yet :(

[@indramal]

Thank you very much. Don't you use ROS2_Control?

[@roboticsandroslearning8232]

I did use ros2_control

[@exactly.3732]

I am unable to do slam with turtlebot3 in ros2 humble it say gazebo 11.00 is required but i am having gazebo 11.10 any solutions or make a video on full installation it will help beginners a lot

[@nafisahmed6247]

How is the filter for keepout zone was done? was it editing the map file using some kind of image editor ?

[@roboticsandroslearning8232]

Yes, the keepout zones are marked using GIMP editor tool.

[@suleymankara1122]

Thanks for sharing. It tooks my one week to convert it to ros2 humble. Maybe there is software converting automaticaly. One question, in your video 29:38 second, why after running autonomous_nav.launch file not showing map in rviz2? It only shows global map.

[@ErkanUnal.]

What engine did you use? I am using a bldc hall sensor motor and vesc driver. Is it possible to configure these in your project?

[@김도영-o1e]

What a nice lecture!!! ❤

[@tarmiziizzuddin337]

Superb explanation!

[@caiyunwurslin2468]

excellent work! Thank you.

[@aimethierry6413]

Hello, I would first like to thank you for your hard work; unfortunately, I was attempting to redo what you did but can't get the good repository comparable to ros_odrive, and odrive message for foxy; could you kindly share me some link?

[@roboticsandroslearning8232]

Hello, I have uploaded the files required for odrive messages for foxy under "ros_odrive_msg" package. Try to build "ros_odrive_msg" package first and then build agv_proto package. The build should be successful. ros_odrive_msg Package: github.com/bandasaikrishna/Nav2_Autonomous_Mobile_Robot/tree/main/ros_odrive_msg

[@luizcarlosvilasboas7975]

Could you help me about this error: ry:~/ros2_ws$ colcon build --symlink-install Starting >>> agv_proto Starting >>> ros2_control_demo_hardware Starting >>> ros_odrive_msg --- stderr: agv_proto CMake Error at CMakeLists.txt:47 (find_package): By not providing "Findhardware_interface.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "hardware_interface", but CMake did not find one.

03:17 nav1 is fsm but nab2 is bt

[@roboticsandroslearning8232]

Yes, same is said in the video.

[@anas77xd]

we missed you, you are the one who contributed in saving my graduation project

[@usasat00]

I was wondering if you can help me out with my project I have a very similar setup, I'm willing to pay you I don't have no idea how much you would have to tell me, I can send an image on my robot is just not working properly.

[@roboticsandroslearning8232]

Send me a email on [e-mail]

[@debanikroy7496]

Use docker

[@JoshuaMurangaBauer]

Hello there, thank you for the video and all the resources. I'm currently setting up my Jetson nano for a similar project, but I want to run the ROS nodes through Kubernetes for Multiple vehicle/robots control have you ever looked into that already? I would appreciate some directions if any. Thanks

[@gowthamappuraj]

Great work and very much appriceation toward ROBOTICS community ,Thanka a lot

[@Thinker-y4m]

Sir , guide me for visual slam and microros .

[@Horizon-s6c]

Hello there, Amazing video! I have a question, are you using encoder with your robot, and what type of encoders?

[@roboticsandroslearning8232]

The hub motors have inbuilt incremental encoder

[@BandaSaimohan]

Super Anna Great explanation

[@ramanabotta6285]

I was not clear on BT for robotics before, and It is clear now. all thanks to you Sai anna ❤.

[@roboticsandroslearning8232]

Thanks Ramana 😊

[@Gdp_si]

Great work, can you post tutorial on docking ?

[@roboticsandroslearning8232]

I will try to work on it.
