I start a navigation with a known map,and after I specify the pose ,then point to the navgoal,it can generate the path to the goal ,however the robot just rotate . by the way,my lab space is some small. after i move it to a broader space ,and make a new map,then navigation ,still noly rotates. see the cmdvel,the value of linear is always zero. How to solve this problem? thank you!

my robot configuration:I made it by myself ,so it has no name.ros version is fuerte,I read again the navigation,I think maybe it is caused by the "recoverybehaviorenable" of the move_base. I will update my solution and the detail configuration later if I solve it .
