Flight Test Debrief

Flight Test Timeline

The flight test went from about 11:30 - 1:30 @ WRESTRC

  • Test 1: A manual-controlled flight with a pilot

  • Test 2: Attempt to load the pathing MAVLink info onto Mission Planner failed

  • Test 3: Auto-mission of manually set waypoints on Mission Planner

  • Test 4: Another attempt to load the pathing MAVLink onto Mission Planner

Test #1:

Configuration:

The same setup in Houston as the flight test in the previous week.

After the pilot got familiar with the controller profile, he took off the drone in loiter mode.

Obersavtions and result:

Houston still has the arming issue when something gets “RC link not found“ and “GPS1 configuration error“(forgot if this is the exact warning). But the warning disappears after waiting for a while or pressing the button on GPS.

Houston could fly pretty well under the control of pilot

Test #2:

Attempt:

Connected MissionPlanner to drone over COM6 and opened MavLink over TCP port 14550. After scannign QR code timeout error occurred from dronekit.

Problem:

Python script was not able to connect to Mission Planner with TCP → COM 6 over MavLink. Originally tested with simulator which communicates over TCP port. This was indicated by a timeout error in the console which occurred after successfully reading the QR code.

Test #3:

The autonomy group decided to run an auto-mission without the involvement of the pathing script.

Nathan(pilot) configured on the Pixhawk such that I can take off under auto mode when disarmed

Three waypoints are drawn on the mission planner. Houston flew really well on in the auto take-off, hitting the waypoints, and auto-landing

Test #4:

After testing the drone with a direct USB connection the Python script was successfully able to load the coordinates to mission planner but failed to do so via Remote connection. The script kept crashing with the timeout error, indicating it wasn’t able to establish a connection to the drone.

Flight Test Post Mortem // Final Thoughts // Condensed Summary

  • Drone didn’t crash

  • successfully take off auto

  • no control link issue

  • didn’t forget anything

  • good pictures

  • wrong power module type

  • failed to connect the tcp through COM

RCA for Red Items

Create a RCA and keep it as a child page.

Action Items

  • get the issue fixed (tcp through COM port)
  • find PMO2-D module
