Detect target IR test

Pilot: Yuchen Lin Manasva Katyal

GSO: Yuchen Lin Jerry Tian

Note

What is being tested?

  •  Detect target IR validation test and accuracy test

Info

Hardware to be installed, items to bring, batteries, etc (change status to success when installed or plan for installing at flight test is done)

  • Houston Drone

  • 6x 4x 3s batteries

  • IR camera (picamera) with IR bandpass filter

  • 2x IR Beacon

  • Measuring tape

CLUSTER ESTIMATION TEST PROCEDURE (HOUSTON)

Procedure

Goals / Objectives

Knockoff criteria

  1. Setup

Get the script to run (either manually or auto start on bootup)

Script is not running

  1. Place and measure distance from drone power-on location to IR beacons

Know true value of the IR beacon location and home location. Use phone GPS to determine IR beacon locations as a backup.

 

  1. Hover above the IR beacons and fly a few passes at 5, 10, 15m altitude. (we are not doing 20m or above, the accuracy seems too low from previous flight tests)

💻 DEBRIEF

Flight test debrief report

We didn’t bring Wrestrc key fob, calling the number on the gate let us in.

Card 1: Huston IR Cam (Pilot: Manasva Katyal , GSO: Jerry Tian )

1st flight : stablizing

  • Took off in Stabilise @ 11:52

  • Landed in Stabilise @ 11:52

  • Huston was drifting a fair amount in Stabilize mode, so switched to Loiter for future flights

2nd flight: test in loiter

  • Took off in loiter @ 11:54

  • Landed in loiter @ 11:55

  • Was much more stable, verified maneuverability before running IR cam test

3rd flight: 5m test w IR camera

  • Took off in loiter @ 11:56

  • Landed in loiter @ 12:00

  • Produced images from the IR camera were mostly white due to the snow. IR camera is not detecting just IR? Otherwise the cold snow should be black in the images.

  • Impossible to detect the IR beacons because whole image is white.

  • Perhaps look into better bandpass filter.. defer to Tong Zhang Maxwell Lou

  • Also, some images were corrupted (0 bytes)… reason unknown again deferred to Autonomy leads

time gap between flight 3, 4 is due to image analysis on Evan Zhao 's computer

Tested IR camera functionality by taking pictures of people

4th flight: 10m test w IR camera round 2

  • Took off in loiter @ 12:32

  • Landed in RTL @ 12:34

  • Images again are too white to detect any IR beacons (pretty much same result as flight #3)

  • Corrupted images again…

  • Data merge worker died too, strangely

  • At the end went into battery failsafe and RTL’d

    • Current draw was very high due to RPI load + very cold temperatures

Additional Notes:

  • Near the end was getting quite hard to test due to very cold conditions (affecting battery, etc.)

  • TX16S kept going into emergency mode… not sure if this was due to cold or something else

  • 15m test was called off due to lack of image usefullness + very heavy snow

Card 2: Foam Plane Pilot Training

  • Were running into quite a few issues at this point (cold/snow/TX16s emergency mode)

  • Waited inside car for a fair bit to allow things to heat up

  • “Takeoff” & Crash @ 1:23

  • Jerry Tian ran the plane with Manasva Katyal as pilot, on launch noticed an immediate right yaw and roll. Correction inputs were put in quite quickly but had no effect.

  • Plane crashed nose first, and prop as well as a part of main fuselage.

  • Theory:

    • Servos are rated from 0C to 55C, temperature was -15C so were very sluggish in response

    • Also, might need more power, so perhaps add additional prop

    • Frankly takeoff speed was never enough… might need to look into a basic landing gear

    • Enjoy the video below 😭

...

Main Takeaways:

  • Autonomy likely needs to look into IR cam/filter and worker dying issue more, or we need to test in a non-snowed environment.

  • Fixed wing pilot training may require some reworking.
