How to set the x_velocities of TrajectoryPlannerROS?

edit

Hi,

I'm trying to model a UAV in ROS. I am using the gazebo_ros_planar_move plugin.

When I set the min_vel_x and max_vel_x to be a constant velocity in the base_local_plannar.yaml. However, the local planner (TrajectoryPlannerROS) uses zero velocity also. It stops when it reaches the goal.

How do I force it to keep moving continuously even if it reaches the goal. I have written a global path planner that re-plans the path that takes into consideration the kinematics of UAV.

Thanks.
