move_base action server doesn't come up with a real robot

edit

Hello !

I try to run the move_base node on a real robot. When I run it in simulation (with another robot), it works successfully.
But, when I try to bring up the navigation stack on a real robot, the move_base action server doesn't come up.
Indeed, when I launch the move_base node, I get continuously the unexpected following warning:

[ WARN] [1466504490.216963462]: Costmap2DROS transform timeout. Current time: 1466504490.2169, global_pose stamp: 1466504032.8989, tolerance: 0.3000

Moreover, when I run my own C++ node in order to send a goal command, the program stays blocked inside the waitForServer loop, this loop is as follows:

while(!ac.waitForServer(ros::Duration(5.0)))
{
    ROS_INFO("Waiting for the move_base action server to come up");
}

I don't understand why it doesn't work and why when I run the move_base node the move_base action server doesn't come up.
If anyone can help me, I would be very grateful,
lfr
