Task 1: Raspberry Pi/ Camera Testing w/ Houston Objective: Verify the camera colour calibration and system integration Task 2: Tubie Take off Objective: Verify the reinforced airframe and try to fly longer this time Takes 3: Pilot Training Objective: Train new pilot Hardy Yu Task 4: Pegasus hover Objective: Verify the system integration by flying pegasus over the air |

| title | Week Before Checklist |
|---|
|
- Raspberry Pi can collect images with the $200 CV Camera
- Test the imaging repository with the Raspberry Pi and confirm images are taken and stored on the SD card
- Edit the
rc.local and ensure that image collection code runs on Raspberry Pi startup
- Raspberry Pi can be powered onboard the drone. Need help from the Electrical team.
- Raspberry Pi and $200 CV Camera are mounted onto Houston. The $200 CV Camera needs to be pointing in the downards direction.. Need help from the Mechanical team.
- Flight test location booked
- Drone Registration -
- Houston
- Tubie
- Pegasus → flying on vanny registration
- Ensure we have good props for Pegasus after last tests crash

- Systems test - Daniel Puratich
- Check flight controller orientation - Nathan Green
- Check motor spin & rotation direction - Nathan Green
- Check DSHOT configuration (DS300, bidir?)
- Motors plugged into correct pins on pixhawk
- Verify motors 1,2,3,4 in motor test go in the correct order
- Verify motors in a,b,c,d configuration is correct order
- verify rotational response of motors is correct (with more than just audio), move the drone around and check each motors reponse individually
- Check transmitter mappings
- Verify communication links
- VTX/RX - no video on any of these aircrafts
- Controller
- Groundstation
- Ammeter working - Nathan Green
- Verify data logging - Nathan Green checked SD card, its working
- Transportation logistics finalized
- Setting Failsafes, Nathan Green
- normal failsafe set to land
- disabled battery failsafe, dont want it to randomly land
- GCS failsafe set to always land after 5 seconds of no GCS

| title | Morning of Checklist |
|---|
|
- Confirm the Raspberry Pi is securely attached to the drone.
- Confirm the image collection software runs when the Raspberris powered on.
- Nathan Green configuring the GPS so both GPS’s are used
- Nathan Green Setting the controller profile on the radio master
- SDC Vehicle key collected → machine shop is closed, we will not be able to grab the key Hardy Yu
- Batteries Planned for (DON'T LEAVE CHARGING OVERNIGHT)
- Drone batteries & spares - 2 sets for pegasus, 3 houston batteries
- Transmitter batteries - 70% on transmitter
- Battery tester/indicator
- On-site kit together - Daniel Puratich announcing checklist
- First Aid Kit
- Ground station if applicable
- Laptop
- Antenna / Receivers
- Transmitter
- Extra Water
- Power cords / Extension cables
- Wrenches - none needed
- Allen keys (metric ones) - three sets
- Knives
- Tape
- Rope/string - not needed
- Zip ties
- Velcro
- Radios
- Safety goggles - not needed
- Fire extinguisher - we dont have one, theyre out of our budget gg
- Spare foam - not needed
- hot glue gun w/ hot glue stick - not bringing that
- harnesses
- ratchet set
- battery removed for velcro (thin 3d printed thing) for pegasus
- Wrestrc
- Airfame assembled
- ESCs/flight controller wired
- Radio equipment tested
- Channel mappings
- Flight modes
- Motors tested
- Check DSHOT configuration (DS300, bidir?)
- Motors plugged into correct pins on pixhawk
- Verify motors 1,2,3,4 in motor test go in the correct order
- Verify motors in a,b,c,d configuration is correct order
- verify rotational response of motors is correct (with more than just audio), move the drone around and check each motors response individually
- Wiring secured (Harnessing)
- End-to-end test (neglecting props)
- Props require a little gold ring which we did not use during the strap down test, may have caused extra vibrations.
- Check the center of gravity - CG is off quite a bit but because only running two batteries and much less hardware then anticipated it will be reasonable for this test
- All components not on the airframe that are required should be in the flight box (e.g. props & prop nuts)
- Airframe payload - Raspberry Pi + $200 Camera
- Mount to airframe pointing downwards (exact angle doesn’t really matter)
- Spare parts
- Props
- Houston props
- Peggy props
- Airframe components (landing struts, arms, etc)
- wings nuts - n/a
- prop nuts
- any detached components such as angle mount - none needed
- Hardware to assemble these components
- Spare Electronics - we dont have much
- ESCs
- Motors
- Flight controllers
- Receiver
- Ground station Software updated

|
- drive back to bay
- post mortem
- Analytics added to this document
- action items delegated
- Autonomy Tasks
- Dismount Raspberry Pi + camera
- Check SD card for saved images
- Check saved images for purpling and see which camera settings yield best results
- Make note of the best camera settings.
- batteries discharge is delegated -
- batteries at storage voltage confirmed
- Upload logs, Nathan Green
- Confirm wrestrc card is back in the holder

Debrief

After the flight test summarize the timeline of what happened. With timestamps if timestamps aren't given in checklist? Tubie Flight Test 10:15 got tubie fully setup and attempted to flight Tubie @Aidan pilot, @Hardy threw the plane. we failed taking off the plane two times in a row. Both attempts, the plane lost power right after it is been thrown.

Daniel Puratich Directing this section of flight test post mortem! Raspberry Pi Powered w/ 12V What happened: The autonomy houston flight test is scheduled on Oct 21st. The autonomy team got the software ready and installed in the Pi, mech ppl help mounting the camera and pi onto the drone, but the power to the Pi wasn’t done before Oct 21st 8:30am Oct 21st, Hardy Yu Amy Hu who come to the flight test decided to solider the power for the Raspberry Pi themselves in a rush to meet the flight test timeline. Hardy Yu proposed the plan of splitting out the power from the xt60 output of the Holybro PM02D to power the PDB and Pi at the same time. The splited xt60 connect to a usb c breakout board and then power up the Pi. Daniel Puratich also help arrived around 9 and helped on the solidering soldering process and very roughly reviewed the plansolder joints. we We powered the Pi without it ever been tested with multimeter and power generatorsupply. However, later on we found out the xt60 output from PM02D is the battery voltage (12V) and that fried the Pi (rated for 5V).
What we should do to avoid similiar triggic from happening in the future: Any newly created electronics should be tested before used Schematic makes things much easier to review If flight tests prerequisite aren’t meet, we should really consider delay or cancel the flight testand more …. add to this
