Admin Preparation

Your status should read “submitted” when you submit the FTR to our Flight Test Coordinator.

Once the coordinator approves, and a date/location/drone has been assigned, the status will change to “waiting for sub team review”. Once all sub-teams have reviewed and signed off, the status will change to “approved”

Goal Summary

Houston Autonomy Landing Pad Data Collection

Status?

status:APPROVED

Desired Airframe

Houston

Desired Date(s)

Testplan - to be filled out by requesting team

Create ONE table per test-item. Eg: “Landing pad images over asphalt”, “landing pad images over grass”, “landing pad images over grass, high” should all be unique tables.

Use each expand to capture one series of tests, eg “Landing pad detection” or “Auto-tuning”.

Test #1: Landing Pad Automission

Prerequisite

Objective

Knock off Criteria

  • aircraft ready

  • camera mount from mech finished

  • camera focus properly adjuested

  • video logging

  • capture more good quality image from the air that will be used for model training

  • run out of batteries

  • autonomy rep call done

Procedure

  1. spreading landing pads to proper locations

  1. initiate camera logging

  1. set up auto mission in the mission planner

  1. push mission to the pixhawk

  1. takeoff and run auto in mission planner

  1. repeat

  • didn’t crash or damage autonomy devices

  • tried collecting images with manual control instead of auto mission

    • manual control tends to be more flexible also the fly speed is slower than auto-mission

  • after increasing the image size, the camera significantly takes more time to take photos

    • more time needs to be spent on the flight

  • the first flight rpi was taking photos normally but the number of photo taken from the following flights were significantly lower

    • also rpi reports low voltage on power supply message

      • shouldn’t be buck converter’s issue tho we didn’t have DMM at that moment to test voltage

    • suspect the rpi lost performance under very low temperatures (about 0 degrees)

    • a car will be required for the next image-collecting flight test so that rpi and batteries can be warmed up between flights

  • more 3s lipo batteries will be ideal

    • 4 3s batteries we have, one of them has a bad balance port

  • The flight test location isn’t safe

    • 43°28'23.4"N 80°34'01.8"W

    • between the flights when we were checking equipment, there were 6 cars suddenly drove behind us and we first thought they were gonna deal drugs

    • we run the north cornfield across the street

    • it turns out those guys were showing off their cars and driving around the turnabout by turns

  • none

All of these major issues should be addressed via Root Cause Analysis Forms:

  • see autonomy model training channel
