ROS and Arduino with ROSserial | ROS tutorial #10

How to integrate Arduino in your ROS project! In this example we will be using ROSserial to convert an Arduino nano into an interface for the RC receiver and to the two servos. The Arduino will read the PWM signal from the receiver and convert to ROS topic, and, at the same time, will subscribe to incoming topic commands from the raspberry pi and actuate the two servos.

This is a really good demo. Unfortunately the author is no more active on the channel.

I'm thinking to run Keras with ROS for this donkey car... is it possible?

[acevanefan]

I am going to link ROSserial to RP Lidar. Yes, you are welcome to share useful links friends.

[osaydhussein]

This was very helpful thank you so much, any chance you could do one where ros will send message to the arduino based on lidar information something like SLAM

[ozcankosar]

Unfortunately, there is no encoder in the engine of my RC vehicle. So how can I calculate odometry?

Amazing tutorials Tiziano Fiorenzani. I can't run sudo apt-get install ros-humble-rosserial-arduino. any idea? thanks in advanced. it looks like I have to change command

Updating to Ubuntu 18.04 solved the i2c pwmboard dependency problem but ubiquity robotics doesn’t have a prebaked image for 18.04. Great work as always

HI tiziano, after watching your tutorial im try to subscribe into tf topic. everything looks work fine. the serial node can subscribe to tf topic and the tf topic data is well. but when i check the serial monitor i see that the data only update once after the serial node is started and then the data looks static. im using esp32. can you help me pls? or there are better methode? thx

fyi im using lidar carthographer and wants to get the coordinates data into arduino esp32.

I want to communicate between Matlab (on my laptop) and ROS (on another Linux computer). I am using a serial communication (USB to RS232) between the 2 computers. Do I need rosserial in my case ? or do I just publish topics directly from Matlab ? Thanks in advance, and well done on your videos, very informative !!

[osaydhussein]

Hello again 😅, i am having problems installing the arduino ide on my Ubuntu 20.04 its on a raspberry pi, i followed the same steps but the arduino ide wont open any ideas ?

[etiennemekonoudekpanou]

Great project
please, could you share the link to buy the chassi of your robot ?

[moreno]

How to solve this problem:
[ERROR] [1524089506.982801]: Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino.

I have tried several solutions available on the internet, but none has helped.

Hello, first of all thanks a lot for these great tutorials.
If we can control rover via teleop keyboard(raspberry pi) and arduino, what we need to do if we want to add lidar on rover and to do navigation. Thanks

[jordanducille]

Why do I need the raspberry pi....
Could it be done with the Arduino alone or a esp32 chipset

[josepablolopezaguado]

Thanks so much, could you make one on microRos with ros2?

[proplayerplayz]

is there something like this for ros2 ? for humble?

[christopherlazo]

Will this work on STM32 instead of Arduino ?

GREAT VIDEO AM USING ROS 2 GALACTIC SO I HAVE BEEN TRYING FOR WEEKS FOR IT TO WORK WITH ARDUINO CAN YOU HELP ME ON HOW TO SET IT UP
