bro I'm making such an exact delivery robot and I just stumbled upon your video, I have a few questions if you mind helping me out: 1. I saw your LiDAR is positioned around 4 vertical supports connecting the chassis to the upper layer. Do those supports interfere with the LiDAR's scanning? I presume that's an A1M8, is it powerful enough, or is there some technique you used to get an unobstructed 360 view. 2. For my setup, I will run the GUI on laptop and comm. with Pi (headless) over SSH, should I run the GUI on my laptop or run on the Pi and be accessed remotely? Which is better. 3. What other sensors did you use for the robot other than LiDAR, what IMU type in fact. 4. I struggle to find, if any useful resources, tutorials or videos to integrate Qt (C++) with ROS2. Do you mind sharing any? Your project itself is a gamechanger and has inspired more confidence in me just by watching it, Thanks for your useful and valuable work.
Hello, thank you for the video, it looks amazing. I wanted to ask regarding localization of the robot. Are you using automatic localization based on lidar or are you setting manually the initial pose of the robot? I am trying to do localization in pre-saved map without needing for manual set of initial pose. I tried amcl, slam_toolbox localization, als_ros but no luck in ros2 humble. Could you please explain how you did this (if using automatic localization)?
I am doing manual localization but using a script. The last saved /amc_pose of the robot during robot shutdown is published on /initial_pose topic when the robot bootsup.
hi just I was just working on the arm that you made earlier with ROS1 could you help me with the ROS2 stack for the same, we were running through some issues, and great to see a video from you!
These are hub motors, I got it online. Its CPR is 90. roboticsdna.in/product/c/?src=google&kwd=&adgroup={adgroup}&device=m&campaign={campaign}&adgroup={adgroup}&keyword=&matchtype=&gad_source=1&gclid=CjwKCAiA74G9BhAEEiwA8kNfpQePDl0ZSoVrlWHkeibrs1YKors949ARU9bPeAwn9TOmoPDMq0Zf_BoCro0QAvD_BwE
Hi, thanks for sharing. I am sure everybody is searching for gui and android app to control ros2. You are using raspberry pi 4, I have performance problem with it in ros2. Especailly I have planner frequency warning and navigation stops even planner freq setpoint is only 2 hz. How do you solve it?
This is my first time see how to use QT! Thank you
Great work.. would really love to see the real world applications of this project
I got it I finding this for long time
You impress everyone
Thank you so much
I appreciate your telent ❤
Such a wholesome video, kudos!
thank you for the video it inspires me so much
thank you. He has been guiding me.
Very informative 👏🏻
awesome work brother!
amazing work 🔥

Great work..I am also studying ROS, can I ask how to make the robot stop until the obstacle moves out of the way? thanks
I am still trying to make changes in local planner to stop the robot when an obstacle is detected. I will publish when it is completely working.

Thank you. Ros2 nav2 code is shared in my previous video. Below is the link

Great job
about the Brushless dc motor , ti is has encoder also ?
Yes. These hub motors are BLDC motors and it comes with inbuilt encoder.
@@roboticsandroslearning8232
I understand that it is hall sensor a,b ,c detect rotor position. ??
Can you tell me what motors you are using and where did u get it how many cpr you are getting
These are hub motors, I got it online. Its CPR is 90.

Have you done any filtering for odometry?
No. There is no fusion or filtering of odomerty in this project. The odometry is from wheel encoders only.
@roboticsandroslearning8232 I am understanded . Thank you for answer.
Hi, These are very cool. We need atleast 4 of them for our hotel and restaurant. Please let me how can we get in touch with you?
Please email me.
perfect bro
amazing ❤❤

I did not face any problem with pi 4. Mine is 8 GB version.
Which language used to create gui
C++
does this has obstacle avoidance using lidar ?/
Yes, but I made a custom planner that will make the robot stop until the obstacle moves out of the path
hi how to stop nav2 and resume with switch?
Do you mean complete nav2 process or just the current goal ?
are you a graduate student sir
No
@@roboticsandroslearning8232 then like PHD or what is your qualification sir your knowledge is so deep
