* robot now speaks and asks for help when bumper is pressed for some time
Waypoint recorder now subscribes to "robot_pose" topic rather then to "amcl" pose.
This causes the waypoint to be saved at the moment and place the user wants.
Thus, the waypoints can be specified more precisely.
Removed unnecessary include.
