You mean like VNC?

In addition to gvdhoom's comments, the port may not be open and just needs the following inelegant solution at least as

I +1'd this post so maybe now you have the points needed.

Along with the nav message ODOM you need to also publish the transform for baselink to ODOM. This should be described in

I will assume when you say "the Jetson doesn't see the data" you mean you have a subscriber running on the Jetson and th

Then other idea I have is to look at QOS settings. I've not had issues with laser and QOS with RVIZ2 but I had a lot of

You're asking for advice, so lucky for me there is no wrong way to asnwer this. In your situation, I would likely start

How do you know which way the motor is turning if you only use one channel of the encoders? How confident are you that i

Correct. In my install of Humble there is no 'tutorial_interfaces". In my Humble there is "example_interfaces" but there

Looks like you found the issue. Your right encoder is failed.

+1 for planning isolation testing. Do you have an oscilloscope you can use to look at raw electrical signal? I'm suspect

No problem.

Make sure set the gblobal frame in RVIZ2 to scan and see if it then appears. I'm pretty sure it's undr 'Global Options".

How can 1 meter travel be less than both 0.5m and 2m travel as shown in your 1st, 2nd, and 6th forward trials and 1 mete

I suspect no one can help if you don't look through the log files and post the bits that are relevent, and then you also

there is a ROS package called dodo_detector that uses tensorflow and python2. You may be able to get a good idea how to

I just created a new workspace and cloned and built that repository to show you you just need to follow instructions. It

Forward was accurate. Backwards was not. According to ODOM and the laser, the wall followed the robot as it moved back.

I'm not sure I understand your question, but just to be clear the navigation will continue updating the path until the g

Can you explain what HW you have? Like what is powering the motors and is there any feedback like encoders. What you're

In my case I had a X.py program in my ROS2_WS that importing from another Y.py module installed on my system and it ran
