Is the robot moving? The /amcl_pose data is published only on filter
updates, which occur each time the robot has moved a sufficient
distance. The /tf data is published continuously; this is where most
programs look for the pose estimates produced by amcl. To see it, try
tf_echo:

$ rosrun tf tf_echo map odom
