rostopic send msgs to robot in ros control of gazebo didn't work

edit

n@lin-VirtualBox:~$ rostopic list   
/clock   
/gazebo/linkstates   
/gazebo/modelstates  
/gazebo/parameterdescriptions

/linrobot/jointstates  
/linrobot/leftWheeleffortcontroller/command  
/linrobot/rightWheeleffortcontroller/command  
/rosout  
/rosoutagg  
/tf

Then:

lin@lin-VirtualBox:~$ rostopic pub -1 /linrobot/leftWheeleffortcontroller/command std_msgs/Float64 "data: 1.5"  
publishing and latching message for 3.0 seconds  
lin@lin-VirtualBox:~$

I am using ros_contol to control my robot move. I roslaunch the file, no error. but send command with the topic i have, but the robot didn't move.
thanks for help, all.

lin@lin-VirtualBox:~$ roslaunch linrobot_gazebo linrobot_world.launch
