Usage: static_transform_publisher x y z qx qy qz qw frame_id child_frame_id  period(milliseconds) 
This transform is the transform of the coordinate frame from frame_id into the coordinate frame 
of the child_frame_id.  
[ERROR] [1380079370.694111859]: static_transform_publisher exited due to not having the right number of arguments

Here's the problem when I tried to confirm whether my static_transform_publisher is running.

I have tried out to 'roslaunch kinect_frames.launch' with 'rosrun tf static_transform_publisher 0.0 0.0 0.0 0.0 0.0 1 base_link base_scan 100' running on another terminal (just simply fill in some argument). Here's the output.

Just FYI, if the args have 6 numbers then 2 strings then 1 more number the first 6 are interpreted as x,y,z,y,p,r i.e. orientation parameterized by yaw, pitch, roll. If you use 7 numbers the orientation is parameterized with a quaternion i.e. args are x,y,z,qx,qy,qz,qw.

Thanks for the correction jarviscchultz. FuerteNewbie, we would still need to see the command line you gave to get this output.

rosrun tf static_transform_publisher

Well if that is the exact command you used to generate the posted error, then I believe the error is very clear. As myself and @DamienJadeDuff pointed out, the static_transform_publisher requires 10 (or 9) arguments, and it appears as if you didn't provide them. Does this resolve your problem?

It don't really solve but at least I get to understand something. Anyway does static_transform_publisher work on simulator? I guess the simulator itself define the robot x y z yaw pitch roll already.

I don't understand your question about the it working on simulator? The `static_transform_publisher` does one simple task; at some desired frequency, it broadcasts a constant transform between two constant frames. An example of this can be seen in kinect_frames.launch file in openni_launch

@jarvisschultz I have update my output from roslaunch kinect_frames.launch, it doesn't seems working right.

Can you please provide the command that you used to get this output? Did you give ALL the values required on the command line?

There should be 7 numbers then 2 strings then 1 more number. e.g.

rosrun tf static_transform_publisher 0.0 0.0 0.0 0.0 0.0 0.0 1.0 base_link map 1000

OR 6 numbers then 2 strings then 1 more number. e.g.

rosrun tf static_transform_publisher 0.0 0.0 0.0 0.0 0.0 0.0 base_link map 1000

(incorporating the suggestion from jarvisschultz).

I just simply rosrun tf static_transform_publisher

rosrun tf static_transform_publisher 0.0 0.0 0.0 0.0 0.0 0.0 1.0 base_link map 1000 The tutorial doesn't list the tf part in the command line code, thank you for this!
