IR Camera Test (HOUSTON)

Procedure

Goals/Objectives

Knockoff criteria

  1. Setup (prepare drone)

  • A good outcome is if rc.local succesfully runs and images are auto captured and stored in a designated folder

< list of reasons why you would want to stop the test >

  1. Hover at 3-5.

  • Best outcome: Image output is desirable (high quality and emitter light is clear visible with no discernible issues in image quality) and are successfully stored in a logging folder.

  • Acceptable outcome: Images are successfully stored in a logging folder (we will see what why image quality is poor).

due to vibration on drone, images are very blurry.

Weather: cloudy

  1. Hover at 10m

Same as above

  1. Hover at 15m

Same as above

  1. Hover at 20m

Obstacle Detection/Guided Mode (HOUSTON)

Procedure

Goals / Objectives

Knockoff criteria

  1. Setup drone:

  2. a) Ensure the guided-mode script has been uploaded to the drone

  3. b) Switch on drone

  4. c) Run the script (starts the mission, where drone navigates to waypoints in a square, switches from AUTO → GUIDED → AUTO, completes mission and returns to landing)

  • Good outcome if drone completes the auto-guided-auto mode switches seamlessly, drone continues its auto mission after diversion, and returns to land.

IMP: pls see photo before reading the description below!

  • The mission is setup as follows. connection initialisedinitialized, armed, takes off 10m altitude, flies 10m NW to the first vertex of the square, flies 10m E to the second vertex. When the drone is about to arrive at second vertex, it switches from AUTO to GUIDED to simulate a diversion and navigates to a waypoint 7.5 NE of current pos. After reaching this intermediate wp, drone switches to AUTO, continues to 3rd waypoint. Just before it reaches the third waypoint there is another auto-guided-auto switch, abrupt change in velocity component direction. Then we carry on naturally to 4th wp. halfway between, we auto-guided-auto (through ned_waypoint this time) to another intermediate wp (see photo), return to waypoint originally navigating too, and initiate landing procedure.

  • 10m S, 4th waypoint 10m W, signifying the completion of the auto-mission. The drone then returns to landing position and lands gracefully.

< list of reasons why you would want to stop the test >

Pilot intervention is not necessary unless safety issues arise, or there are environmental disruptions, as the auto → guided → auto switch is handled by the script.

if at any point the pilot needs to take control: 1) kill the script, this forcefully changes drone mode to loiter (tested on MP), and then aborts the current mission. 2) Pilot has manual control over the drone

NOTE: on mp, simulating a mission-abort, ie. killing the script changes mode to loiter almost instantly, but drone altitude plummets to zero. (discussed with Andrew and it should just be a MissionPlanner default issue). However, just in case, pilot should be ready to control vertical throttle when aborting mission (when killing the script)

315 deg (i.e. in NW direction)

Good

  • Geolocation logs worked, will update with photos after checking them

  • Auto starts with Houston when powered up

Bad

  • Camera direction needs to be labeled for installing

    • Distance/offset for camera location needs to be known at some point

Recap

Cloudy weather

Grass in the background

IR emitter set on top of controller box

Flight 1 - 5 m

Flight 2 - 10 m

Flight 3 - 15-20 m

Good

  • Lots of images

  • Different altitudes

Bad

  • Not great images

    • Need a better camera with global shutter due to vibe and drifting of drone

  • IR camera broke before flight test, glued back on (Nathan glued it)

  • Took a while prior to leaving for flight to get set up on Pi

Flight Card 3

Recap

Flight 1 - completed script

Flight 2 - tested canceling script switching to loiter

Good

Bad

Flight Card 4

Recap

Good

...

  • Script completed well, armed and took off drone in auto and successfully switched from Auto to Guided at flags

Bad

  • Could not switch from Auto/Guided to Loiter in the middle of the script

    • Was able to switch to RTL though

  • RTL switch to Loiter cut thrust and drone fell, caught with RTL but switch to loiter caused same issue

    • Hard landing, nothing was damaged

    • Thrust on controller was at 50% during this too

    • Test script on drone with lower altitude to problem solve switching to loiter issue

      • Simulation successfully switched from auto/guided to loiter, but did not translate to real flight

Action Items

  • Check photos for IR and Geolocation

  • Check path from guided mode and compare to simulation

  • Check RTL to loiter transition issues
