Giving Our Robot a Brain - Raspberry Pi

[@annamcfarlane9563]

Another great video! raspberry is my second favourite type of pi LOL

[@雷晨光-t7o]

Another awesome video! Now I'm looking forward the next one!

I just woke up to the notification, read the thumbnail as " Giving our brain a robot " xD, but anyway, amazing video, just like the rest of yours :D

Hahaha yeah maybe one day I'll start covering neural implants ;) Thanks!

Why use ubuntu mate instead of Ubuntu?

[@giacomoburani9043]

Hi everyone, I'm really new to robotics and I'm using these amazing tutorials to learn a bit more about ROS. I'm a bit stuck on the talker-listener demo for two machines. I'm able to ssh into my pi (Raspberry Pi 4 model B) from my developement PC, but when I run the talker program on the Pi, my PC doesn't hear anything. Any help is appreciated.

[@giacomoburani9043]

solved!! I ran the command: sudo ufw disable on both machines and now I'm able to communicate

[@ArticulatedRobotics]

I'm glad you were able to get it going, I'll have to tuck that one away for my own future reference!

[@Adroitbit]

I guess the funny thing is RPi is still in short supply. I can use laptop instead anyway.

[@ArticulatedRobotics]

Oops, sorry I didn't reply! Yeah, unfortunately they are a bit hard to get a hold of at the moment :/ The good news is, as you say, we can start development on a different computer, even running simulations etc, and transfer the code to the final hardware once it's available :)

[@雷晨光-t7o]

Excuse me.May I ask a question？ Does the plugin of Gazebo can only be written by cpp？Can it be written by Python？

[@ArticulatedRobotics]

Hi! I've never actually written my own Gazebo plugin (one of the great things about ROS/Gazebo is that it comes with so many that I haven't needed to), but yes, to the best of my knowledge Gazebo plugins must be written in C++ so that they can interact directly with the Gazebo backend at a low level.

Gold. Thank you.

Great video !! Keep those coming

[@ArticulatedRobotics]

Thanks!

Doing simulation only on my end, but I figured there's a lot of good info here so I'll take a look anyway. Great tutorial project, excellent first build! Thanks for making it

[@dalasmx4453]

I have seen the most of videos of this journey, but I have a question, can I use my raspberry as the main of all the programming? I mean, I can install Ross there and make all the stuff program instead of use a laptop or desktop with Ubuntu? Thank you so much for you support and all these videos

[@Mr-lw7gy]

For running software like ROS/ROS2 should be no problem assuming you aren't doing any heavy CPU load like SLAM etc. For programming I would try to find a cheap/used laptop. It would be a much better experience. When it comes to running simulation like Gazebo on the PI I don't think it is too easy and very limited.

[@ccrzvids2]

Great video! Anyone have any tips for finding a raspberry pi or jetson? They seem to be pretty hard to come by these days.

[@ArticulatedRobotics]

Thanks! Unfortunately you're right, there is a bit of a shortage these days - I'm glad I got mine a couple of years ago! If you happen to be in Australia, Core Electronics usually has at least some models in stock core-electronics.com.au/raspberry-pi-4-model-b-4gb.html (and their warehouse happens to be in the same town as me), but perhaps some other viewers will have ideas on where to get one internationally.

[@jemarigondon4425]

Is ros 2 foxy compatible with ubuntu jellyfish?

[@prathamvjain7569]

No

[@prathamvjain7569]

But ros humble is compatible, if you are from India you might face issue in downloading ros humble

Great video 😊
