I would really want to see a tutorial on how to send the robot to some location once you finished mapping ; Thanks in advance !

[@TheArcanis87]

Amazing ROS tutorial! I'm learning ROS and it helps a lot your step by step tutorial explaining what the commands do, and how to make it works. Thanks for sharing!

[@Hybrid.Robotics]

I have been using the Sandisk SD cards and have never had a problem with them. I have reformatted and reloaded operating systems on them many times. :) Samsung cards would also be a great choice.

[@fdtank81]

This is awesome
Can’t wait to see the finished version
Following closely
Great job

@2:30 Its call slip rings. They have metal disks touching each other so the two sides can rotate independently and still conduct power / data.

[@AndrewTSq]

cool, i was thinking it used induction from rotation and wireless data

[@lorisrobots]

I wish I had been able to catch this one in the live stream Really nice intro to using this technology. Thanks Kevin!

[@44gala]

Amazing tutorial. Explanation & demo is awesome and easy to understand

[@RC_Ira]

Amazing video, excellent work my friend!🎉😊

[@Fourgees_4GS]

Very informative. Thanks for this info.

[@garycroftsmicroscopy]

Very good work Kevin

[@aldoseba]

You should do a 3D lidar project that at first maps the surrounding environment, save it and compare all the time, when it sees flyes or mosquitoes, shoot a laser to kill it

[@johnm4962]

great video

[@ElfaInc]

BTW - The ~ Symbol is called a "Tilde"

[@Midotaha1234]

Hi , the /tf topic is not showing when I type rostopic list. Do you have any idea why ? Thanks for the great tutorial

[@kevinmcaleer28]

I think you have to start that in another session too

[@hawk453]

Hey how have you connected your raspi to the laptop???? I have been trying a lot to run rviz on my laptop using vnc,,,but it doesnt work,,,could you please help me on this

[@zainimran8824]

Hey! Im sorry its been quiet a while since you uploaded this video, But I was wondering were you able to implement Hector SLAM on this robot?

[@kevinmcaleer28]

The raspberry pi zero isn’t quite up to the task - you can do it with a raspberry pi 4 - Build a ROS robot - Learn ROS with me Part 1

[@tezc1197]

Is there a way to build something like this but using GPS coordinates

[@dannykangaroo8143]

On the section of installing rplidar, when I do catkin_make, i get an error, Invoking “make -j4 - l4” failed. Any ideas on this?

[@agrimekatronik321]

Hello,thanks for these great tutorials, I cant find the hector slam tutorial,did you make it?

[@kwidmayer]

Is it possible to use this with the LiDAR sensor rotated 90 degrees, up and down rather than side to side?

[@kevinmcaleer28]

You could but then you wouldn’t be able to navigate, which is what it’s designed for

[@davidjijo6657]

really good videos, please add a timestamp next time :(

[@rcarrasquel.u]

Q: Hello. Do you have a video where you explain how to configure the lidar measurements in the transform? . I don't understand the official documentation

[@TheRealFrankWizza]

Funny story, when I when I went to install ubuntu, they only have a server version of 20.04 on the imager and the ubuntu website. Ubuntu MATE, has a download for 20.04 on their website.

[@danyarRobotics]

hello dear teacher sorry I have a question I Can download ros on ubuntu desktop 22.04 LTS? I use raspberry pi 4 thanks for answer

[@davisogunsina1294]

Use raspberry pi imager to flash ubuntu 22.04 server into an sd card and install ubuntu 22.04 desktop.

[@sohaib3088]

Is it possible to install Rviz on Raspian OS?

[@kevinmcaleer28]

It’s not a supported configuration (TLDR - it won’t work)

[@sohaib3088]

[@razanad3333]

Q please may you list the components in this video?

Q. Rostopic command not found bro

[@Tio_Sam00]

Hey, can i use the raspberry pi pico with Lidar?

[@kevinmcaleer28]

The Pico can’t run ROS directly (that requires a full OS and Gbs of RAM), but you can add LiDAR to Pico’s as it’s just UART data

[@Tio_Sam00]

@@kevinmcaleer28 thanks for the response. which Raspberry would you recommend then? I'm doing a school project and I need to build an AI robot, and I'm using LIDAR
