Hi everyone,

Now I am following rviz tutorial to control interactive markers. I want to edit the code in below link to let the marker move towards one direction every 5 seconds automatically without dragging the arrow:

I have added a for loop in the code and changed box_marker.pose.position value for each loop. But the marker didn't moved and its length got extended. Would you please instruct me which value should I change to meet my requirement?

I appreciate your help.
