[@oop1761]

jazakallahukhayran ive been reading for hours and your 15 minute video explains everything

[@robotisim]

Alhamdullilah :)

[@milosnikolic1790]

MicroROS is amazing, make more videos on this topic please! 😊

[@robotisim]

Thank you! Will do!

[@luccarigueira8319]

Your videos are incredible, im learning a lot about ros2 and robotics in general. It is helping me in my personal project. Thanks, from Brazil

Salaamuallaikum Hello all, I run into a bug which is I am working with a micro-ros agent. I have established the connection between my microcontroller (esp32) and the agent.however, when I run ros2 topic list, I don't see the topic listed. from the video, at the 11;30 sec part. for me I dont see the line schema you mentioned

[@robotisim]

walaikumslaam , can you post eror somewhere so we can see discord would be the best

[@sulemanafatoamaabdulai1305]

@@robotisim Thank you for your prompt reply.. Alhamdulillah, I manage to solve that error, I realised I was not running the publisher code node on the main.cpp file. But please, I have some genuine concerns, I would love to connect via discord, please whats your discord acc?

[@houssemzouda4991]

Thank you bro !

[@robotisim]

You're welcome!

[@AhmedHendawy01]

Thank you, great tutorial!

[@Hailongfilm]

Can you connect mico ros agent via udp ? I can connect but sometimes it works, sometimes it doesn't

[@AhmedHendawy01]

@@Hailongfilm I havent tried it udp only serial, could you clarify what happens exactly or the error logs

[@robotisim]

You're very welcome!

[@robotisim]

Yes i have shown it in video

[@TheAiPioneer-h2z]

I have a question, I want to use Micro-ros in my device. I am also connecting an esp32 and an Arduino Mega to my system. I am doing serial communication between esp32 and Arduino Mega (RX TX). Will my esp32 be able to communicate with my laptop and the esp32 at the same time ?

[@robotisim]

Theoratically yes not a problem for - Serial COM with Mega then Wifi Com with Laptop how ever it totally depends upon the bandwidth and frequency you are using for the task but it will slow down for higher freq-bandwidth , still will keep connected :)

[@Hailongfilm]

Hello, I have problem with connect via udp, If i "ros2 run micro_ros_agent micro_ros_agent udp4 --port 8888" sometimes it works, sometimes it doesn't. Do you have solution?

[@robotisim]

Check ESP32 , is it working fine

[@hashantetv]

i downloaded docker in my windows as in one of your previous videos can you briefly explain how i can install microROS using VS code in my windows and docker... pls reply ....

[@robotisim]

Gona take time

[@masdikaaliman6425]

Assalamualaikum sir, i try this on arduino ide using wifi communication in esp32 wroom32d i got error guru paniced with some backtrace. But it will work properly on diffrent board

[@robotisim]

It is for PlatformIO only Arduino ide will not work

[@Astronerfabz]

can you plz make a video of wifi enabled and control and how to control multiple micro Ros robot like swarm by the by nice video really informative😍

[@robotisim]

I will add your request on the List

[@sharathnarayan4234]

I didn't see any micro ros topics while doing ros2 topic list, but I'm getting output in another window.

[@robotisim]

Export Domain ID and make sure you are on Same Access Point ( WIFI)

[@storyspark57]

Can we use esp8266 instead of esp32?

[@robotisim]

Check the MicroROS Wiki for that .

[@kaijustice7048]

I love this tutorial! I have a Portenta H7 that I am working on getting up and going with Micro ROS. Following your tutorial, I receive an interesting failure during debugging, any thoughts our comments would be appreciated!

do not know whats that.

Sir I'm facing problem in microros communication with esp32. Can I mail it to you? If yes please provide the id.

[@robotisim]

Post it on ROS robot exchange stack and provide link here

[@robotisim]

because there are more knowledgeable people than me as well :)

Esp32 stop receiving data through microros I have posted it there with above title.

[@simonrism]

Assalamuwalikum, Thank you very very much !!! I really really appreciate your work and help. I was stuck for a week with installation, where as your efforts benefits me enormously. I would like to ask you something, "Could you please make a video that blink LED light using ESP32 board and LED light can be controlled with ros2 pub_&_sub?". I wish you best of luck, Allah bless you!!! Thanks, Simon

[@robotisim]

Walaikumsalam.

[@MOHITKUMAR-xe7bg]

can you pls give the buying link for esp32?

[@robotisim]

ESP32 Dev V1 module

[@FBPrepping]

I want to build one much larger to sweep and clean my floors.

[@robotisim]

build it then :)

[@Ib.m86]

When I build the platformio on my device I am getting this error: ImportError: cannot import name 'OVERRIDE_OPT' from 'em' (/home/ibrahim/.platformio/penv/lib/python3.10/site-packages/em.py) The Python package 'empy' must be installed and 'em' must not be installed since both packages share the same namespace. I tried to reinstall empy and remove em but nothing changes, I am using Ros2 humble and platformio in vscode and python3.10

[@robotisim]

Strange . Provide details of ROS Stack Overflow . With screen shorts and logs So i can understand what is going on .
