Robot not moving in ROS Navigation

Hello, I’m unable to run the move the robot even after running the command:
roslaunch turtlebot_teleop keyboard_teleop.launch

I’m in the first chapter 1. Basic Concepts. Is there a glitch, or am I doing something wrong?

Hi @padin ,

If the robot is Turtle Bot “3” , then you could try this command:
roslaunch turtlebot3_teleop turtlebot3_teleop_key.launch

I am not sure if that would work, but you can try it and let me know.

Hello @padin ,

I just tested the command in this course and it’s working Ok for me. Please make sure that you have the focus in the Shell where you are running the program (ie. if you have the focus on the simulation, the program won’t detect the keys you are pressing).

Thanks for the reply. Yes, I have the focus on the Webshell, and it changes the angular/linear velocity when corresponding keys are pressed. However, neither the gazebo nor the rviz responds to the teleoperation.

Oh sorry. It’s my fault. I was pressing a-w-s-d-x keys instead of u-i-o-!

Interestingly, when I press a-w-d-x, the angular and linear velocity changes, yet nothing appears on the scren.
