I'm following the instructions for installation of hector quadrotor indoor slam demo from here (I've also mentioned them below):

mkdir ~/hector_quadrotor_tutorial
cd ~/hector_quadrotor_tutorial
wstool init src
source devel/setup.bash
roslaunch hector_quadrotor_demo indoor_slam_gazebo.launch
roslaunch hector_quadrotor_teleop xbox_controller.launch

But I get the below error after running the last line

ERROR: cannot launch node of type [hector_quadrotor_teleop/quadrotor_teleop]: can't locate node [quadrotor_teleop] in package [hector_quadrotor_teleop]

How do I fix this error.

here is the full content which was returned
