Announcing T3-2, Round Two: the autotakeoff and landing round
It's time for the second round of the second season of the Trust Time Trial (T3) competion! This round is an autotakeoff and landing round, with 3D waypoints. Like the last round, there are two divisions: plane and copters.
Your mission in this round is to complete the course diagrammed above. Your UAV must autonomously do the following:
- Autotakeoff. NO MANUAL CONTROL. This must be fully autonomous launch, with the RC transmitter on the ground. For aircraft we will accept rise-off-ground, catapult or hand-launch (but remember, no transmitter!). For copters, it must rise-off-ground. Just flick your RC transmitter's mode toggle switch and put that bad boy on the ground while you watch the show.
- Hit the above eight waypoints, which are in increasing and then decreasing height (the target altitude is given after each waypoint number). They are all 100m apart, for both planes and copters. The exact position of WP8 (or however more waypoints you need to end the mission) is not important--it is just whatever you need to set up your landing pattern properly.
- Autoland, as close to your launch position as possible. Again, no transmitters!
To enter, post the following in the comments below:
- KML track and screenshot of your track in Google Earth, with launch and final rest positions marked.
- A description of your vehicle and autopilot.
- Because this is a hands-free round, we want videos of the whole thing! Upload them to YouTube and embed the video in your entry.
Gary Mortimer, as always, will be the judge. In this case it will be scored primarily on "style": he will use qualitative rather than purely quantitative measures to reward clean patterns, tight altitude control and the closeness of the landings to the takeoff points. Note: experience has shown he can be influenced by creativity and fun, so make those videos count!
There will be three winners in each category (planes and copters), with the #1s getting a $100 gift certificate at the DIY Drones store and #2 and #3 getting $25 each.
All entrants who successfully compete the course with a copter, regardless of place in the judging, will receive a flying robot merit badge!
This is a pretty tough challenge and the weather is still dicey in the Northern Hemisphere, so you get two months for this one. Deadline is Sunday, March 4th, at midnight PST.

If there are may points it is harder. The Auto takeoff and land I did a long time ago. Truly. It took many tries.

Hi Chris, quick question. regarding WP8, when you say: "it's just whatever we need for the landing pattern"
For fixed wing, we can add WP9, WP10... to reach home right? or we only have the freedom to choose the position of WP8?

eagle: yes, that's right. I've edited the above to make this more clear.

This is an excellent challenge guys. I'm looking forward to giving it a go :)
Would it be okay if I do the mirror image of the above graphic, i.e. a left hand circuit? My flying site typically has wind directions that would put a right handed circuit over the pits area; I'd hate to have to do a downwind takeoff and landing!

Colin: Sure, that's fine.

Hi, is it ok to raise the altitudes, say add 25m to each point? There are obstacles (trees) at some of my flying sites and I don´t like to touch them :-)

Yeah thats fine Marc, looking forward to your entry. Remember stay below 400' agl max though.

Can the take-off and landing WP basically be the same as WP4? Keep it as a box, for copters?

Here a video of the T3 2 rounds mission competition with the firmware ArduCopter v2.1.1 R9 connected in HIL mode with an APM v1 (APM 2560) board through the Mission Planner v1.1.19. The flight plan follows exactly the T3-2 mission.
Regards, Jean-Louis

I definitely will give this a go. I've never even done auto Land and takeoffs but i think two months is enough time i wish you had a merit badges for fixed wing that's awesome !!
