Hi, I am using ROS kinetic and since the tutorials on is a littile bit out-dated, I followed the answer in .

It did compile and roslaunch the demo successfully. I've checked the rostopic list and found there is actually a topic called /cmd_vel. I tried to use this command to let the quadrotor take-off

rostopic pub -r 10 /cmd_vel geometry_msgs/Twist  '{linear:  {x: 0, y: 0.0, z: 1.0}, angular: {x: 0.0,y: 0.0,z: 0.0}}'

But the quadrotor still stays on the ground. I used

rostopic echo /cmd_vel

to check if the message is sent to the topic correctly, and it does.

Does someone know what can be possibly wrong?
