Dev Call jan 22, 2024

Issues & Pull Requests



Attendee count (max): 16

UTC1100 - Conference update

  • Annual developer conference
  • Reno Stead probably ruled out
    • We’re too big for conference
      • 50
      • Really training rooms
    • Too small for flying outside
  • Maybe a local airfield?
  • Tom’s concerned the numbers could absolutely explode
    • A hotel which can expand as the attendance grows?
    • Reno can do that sort of thing
  • There’s a group in Japan that was interested
    • DroneJapan which runs the drone school in Japan
    • Run events all the time
    • Kaga City
    • Northern coast
      • A bit of a hike from Tokyo
      • Shinkansen 4.5 hours, 3.5 hours after an update
      • There are direct flights Sydney->KMG (near Kaga City), so probably same from other major airports
    • Lots of flying opportunities
    • Planes, multis and boats
    • (Randy shows powerpoint with lots of cool things)
    • Drone Japan would do a lot of the work to set things up
    • Candidate dates:
      • Oct 18-20
      • Oct 25-27
      • November 1st to 3rd
    • Weather should be mild on all of these
    • Week after Randy’s competition
    • Visa waiver program should make things straight-forward
    • Considerably easier to get to Japan than Canberra
    • Group houses?
      • Worked really well in Canberra
    • “Too old for Royukan”?
      • They were thinking more regular hotels
    • Maybe cheaper than Canberra, too
      • Smaller town
  • So maybe Japan this year, Reno next?
  • Randy might head over to have a look
  • Maybe put something out on the mailing list
  • Come back next week and make a decision
  • FliteTest was also considered
    • Maybe 2025 if Reno can’t work?

UTC1134 - AP_Periph: send temperature and Vehicle: receive temperature by IamPete1 · Pull Request #25993 · ArduPilot/ardupilot · GitHub

  • Send temperature and receive temperature, move up
  • Subscribing to everything in AP_DroneCAN.cpp is a anti-pattern
    • We should move stuff out of this file!
      • AP_DroneCAN.cpp shouldn’t know about xact, for example

UTC1142 - AP_Scripting: add lua implementation of Copter's target location bindings by robot-to-society · Pull Request #26013 · ArduPilot/ardupilot · GitHub

  • Add lua implementation of Copter’s target location
  • Interesting race condition when you want to update a location based on the old location
  • LUA script must ask for current location, create a new location, send both back in
    • Copter will reject the target location update unless the passed-back-in original matches the current target location
    • Carried over from bendy-ruler C++ code
  • For Copter ship landing?
  • The LUA bindings needs a massive comment explaining the idea behind the update calls
