Turtlebot3 is not operating by keyboard

edit

Hello everyone,

I am trying run the Turtlrbot3, every command is running and I gave the command roslaunch turtlebot3_teleop turtlebot3_teleop_key.launch. It is also working and while pressing the keys "wadx", it is showing:

w/x : increase/decrease linear velocity (Burger : ~ 0.22, Waffle and Waffle Pi : ~ 0.26)
a/d : increase/decrease angular velocity (Burger : ~ 2.84, Waffle and Waffle Pi : ~ 1.82)

space key, s : force stop

CTRL-C to quit

currently:  linear vel -0.08000000000000006  angular vel 0.2999999999999998 
currently:  linear vel -0.09000000000000005  angular vel 0.2999999999999998

But, Turtlebot3 is not moving I checked the rosnode as well:
