Can raspberry pi 3b+ run ros noetic

edit

I'm planning using lidar sensor to draw a map with ROS gmapping and because pi 3b+ only has 1GB RAM. So I doubt that it would have enough RAM to run ROS and control 18 servos and 6 force sensor, but I don't know how to estimate memory using

I guess the only problem here is gmapping. If gmapping is only executed one time per "cycle" maybe you can try it with rpi 3B+ (probably slow af when gmapping up) but if you want to have gmapping continuously running, you might have to buy a rpi 4 of at least 2 GB of RAM (4 GB better) I was running ARUCO detection in 3B+ (can´t remember the size of the ram) and it was slow as hell but ARUCO algorithms are unoptimized.

Not ideal but opencv detection in ARUCO can run with 2GB RAM with C++ and that should help you with speed.

@osilva Can´t remember the amount of RAM but it really was slow. Can´t either remember if ARUCO was implemented on Python or C++ hahaha

I don't know this statement can help you or not, but you should consider it.

1. If you decrease the size of your video stream to lower pixels.
2. Instead of RGB channels just use black and white.

I think that can saves a lot of raspberry pi resources and can be helpful for Aruco detection.

@Ranjit Kathiriya Thanks for the help but that was not an issue. I have already overcome that.
