OS Version: Ubuntu 16.04.4\r\n2. Git tag: master\r\n\r\n3. Workspace structure\r\nI clone the rosflight and rosflight_joy repos into src directory of my workspace. When running catkin_make everything compiles cleanly and after sourcing the devel I can run the nodes.\r\n\r\n4.Joystick: FrSky Taranis\r\n\r\nFirst thing that is different from the steps in the docs is that rqt_graph doesn't launch automatically. The rqt structure I see after running all the nodes and launch files is this:\r\n![image](https://user-images.githubusercontent.com/6543766/39042751-eb01598c-448b-11e8-9201-0efb2e7d3093.png)\r\n\r\nAlso in Gazebo the undercarriage of the drone is below the floor level (seems it doesn't have collisions enabled?)\r\n\r\nEven though I got everything to run I see error messages when trying to arm the quad. I made a call to calibrate_imu and calibrate_baro and the error in the rosflight_io is \r\n```\r\n[ERROR] [1524214501.767272762, 464.493000000]: [Autopilot]: unable to arm due to error code 0x1\r\n```\r\n\r\nI was trying to find some information about this error code in the docs and even source code but didn't find any useful information. Would you be able to point me in some direction?\r\n\r\nThanks!"}}
