Hi, sorry for my english. I beginner in Ros and I'm trying to send a goal to simulated pr2 robot in gazebo. For this, I'm following SendingSimpleGoals tutorial. Previously, I've run the following commands in differents consoles:

roslaunch pr22dnav pr22dnav.launch

roslaunch pr2gazebo pr2empty_world.launch

rosrun pr2tuckarm tuckarms.py -r t -l t

rosrun mapserver mapserver map.yaml

roslaunch pr2navigationglobal rvizmovebase.launch

When I clic and drag "Set 2D Pose Estimated" the Pr2 move to indicated pose but when I clic and drag the "2D Nav Goal" the robot stands still

The goal topic is run:

rostopic list | grep move_base/goal

return move_base/goal

Anyone could help me?

Thanks in advance
