Issue:

I’ve set up the TurtleBot 3 by following the manual provided on the website. Everything is running fine until bring-up, but after bring-up, I’ve failed to run the teleop operation using the keyboard.

A few points to be noted:

  1. Both our pc and tb3 is connected to the same WiFi, which supports multicast
  2. pc and the th3 is connected through ssh
  3. The lidar sensor of TB3 starts running as soon as I turn on the OpenCR button, but I’ve seen many videos on YouTube where they run the bringup command and then the lidar sensor starts to spin. Is that an issue?

Software Interface:

TB3
ROS2 humble
Ubuntu 22.04

It is normal for the lidar to start spinning when Turtlebot is turned on.

Make sure the DOMAIN is the same on the SBC and remote pc.

nano ~./bashrc

Check this line

export ROS_DOMAIN_ID=30
