I just started the course. In the introduction I need to launch a file that will allow me to control the robot using some keys in the keyboard. However, when I try to do it, nothing happens in the simulation. The log shows the speed when I change it but the robot does not change its behavior, it only rotates in place counter clockwise at a pathetic speed.
This is the only line that write in the terminal:
roslaunch turtlebot_teleop keyboard_teleop.launch
And I try to use these commands:
Moving around:
u i o
j k l
m , .
q/z : increase/decrease max speeds by 10%
w/x : increase/decrease only linear speed by 10%
e/c : increase/decrease only angular speed by 10%
space key, k : force stop
anything else : stop smoothly
