hi,

i want to control the kobuki without sensors. i only know how to control it using keyboard and set goals using 2D Nav Goal in rviz. Now i have the goal msg "x,y,z," and "quaternion" one by one. But i don't know how to send it and receive it. Do I need to write a lot of code ? Do you have any idea or dose there have a tutorial about this? Thank you very much!

Thank you very much! Now I have the message geometry_msgs/PoseStamped. But the kobuki need geometry_msgs/Twist. The package move_base has the way to tranform between them. But I don't have sensors and just want to control kobuki. (poor code reading for me..)Do you know how to transform?
