T3 Back to the Future


Remember back, way back in autopilot years probably about 20. The year 2009 and the first round of our gentlemens (ladies are allowed just none have ever entered) competition the T3 challenge.

Back then just flying way points was hard and all this gear was expensive. Ardupilots were made at Sparkfun in batches that ran out quick.


Lets try it again I suspect this time the challenge would really be flying it faster than somebody FPV racing.

Read about the first time here for hints and tips. 

As tech has moved on all aircraft types welcome lets make it not above 50m and 5 laps. All of course autonomous. Extra marks if that is from take off to landing.I will count the time from take off to landing so screaming dives to the start will not help. KMLs as evidence please!

UPDATE: Rovers (and boats) are also allowed! There will be a special rover/boat class, and you only have to beat other vehicles in that class. The course for such ground/water vehicles is 100m x 100m. 

I will accept FPV times for the sake of science and should they be much much quicker it will give the pure FPV crowd something to brag about.

An Easystar (yes before HK copied it) made one lap in less than a minute in 2009 so 5 in 5 minutes should be more than possible. 

As ever the time frame is flexible but why don't we all meet back here on August the 1st and find out who won!

Please add your entries and adventures below. Points are always awarded for silliness, just as long as its safe!

    Thanks for sharing the link healthyfatboy, and congrats on winning the rover class.

    Thanks to Gary and Chris for organising and for the prizes! We received a new pixhawk in the mail yesterday..perfect timing to go into a new and refined Eaglet, picture attached :D

    Looking forward to the next T3.

    Ah excellent.  Thanks for posting the link here - I missed it when I was OS.

    They closed it out two weeks ago.

    Gents, perhaps we could close this challenge out?  And the challenge before too?  Some of us would like the T3 tag. (;

    Any updates on results?

    Just as an update but here is a link to one of my better runs I got on video during the day.

    I still had to take it out of auto once or twice during the run but you can see it navigating relatively well. There were a few close calls with the light poles in auto mode that you can see.

    My setup is pretty lame with the compass not even level but I did the proper calibrations and it seemed to work well. I had to return the Pixhawk/GPS combo since it's finished but I can try to dig up a picture of the setup when I get home.

    The gavel falls, its August 1st!

    I will now in conjunction with Chris sort the results.

    I just realized I may have okay video footage of one of my runs. It's not of either of the posted runs but one from a morning test run. I'll dig around for it and post it up tonight.
