Amazing! I will go through the videos to learn more about ROS.

[underlecht]

Just found your videos. They just are amazing. Thank you, and I am continuing watching them:)

[amortalbeing]

thanks a lot just subbed recently. keep up the great work :)

[gfzucatelli]

Muito bom seus vídeos. Saudações do Brasil!

[kadirguzel]

Just found your videos and documentations on your web page. Thank you, I am subscribed. Please keep going :)

Subscribed and liked! Getting back into ROS development after a short break from academia and found this video helpful. Topic suggestion would be how to use dockers/singularity instances and how to communicate with them. For example running ROS2 on host and wanting to access ROS1 topics running in a container instance

[jonathans]

Very helpful video, thank you! Question: Can the travel router be used without internet? I.e. solely for communication between the robot computer and base station?

[davidfarning]

Humble tester here :) I skipped the travel router setup and used my home office setup which uses pfsense/unifi. I'll reconsider the travel router option if I want to make things more portable.

I'll try this later. I have a small NanoPi that has one ethernet and one USB port. Ethernet will attach to home network while at home or to base station (laptop) if i'm away from home. NanoPi will have a large Realtek 2.4G antenna connected to the USB port and this will be the access point. Don''t know if Netplan is also 'nmcli' but have found 'nmcli' easy to configure..

Instead of buying a travel router can I use my smartphone hotspot to make the dedicated network? @2:45

[jaredaceves]

what if I have raspberry pi standard linux as my default os, do i need to uninstall it?

[mikebrascome]

Great tutorial. I do have a question, though. What happens when you network with ROS2, but communication doesn't happen? How do you troubleshoot it? Does ROS2 create any logs?

[kailuwang]

If I only want to simulate with gazebo on VM, should I setting like this video?

[alexCh-lngw]

if your pi is out in the wild using 5g/4g or in general cellular data, you'll need to set up ssh reverse tunneling to gain access to it to minimize the amount of hardware you use.

Thanks for sharing. I am having an error that 2 ros cannot see each other in the same wifi network. Can you help me

[dreamscometrue]

I install VMware on my laptop to install Ubuntu. After I installed Ros2 Humble for both virtual machine and Raspberry pi4. I started testing the link between VM and raspberry with the sample node above (ROS2 Humble). I pinged rasp's IP on the VM and got a signal and at the rasp screen I pinged the ip address of the virtual machine and got a response. But when transmitting "Talker" on virtual machine it shows "Hello world 1, ...." but on raspberry screen "Listener" does not receive "Hello world...". Looking forward to hearing from you

or just use a smartphone hotspot w/ hybrid network sharing

[abdullahrawshan]

Hi I'm having a lot of trouble setting up the network with my virtual machine. Can you help me with this?

[angelhoma]

so, this video is for who wants to use the router?

[chaoyuhou]

After I added the dev yaml file, the VM lost the ethernet connection, a little help please
