Announcing the official DIY Drones Trust Time Trial (T3) Contest

Thanks to the good ideas of Gary Mortimer and others, we're now launching a Trust Time Trial contest. The idea is simple: you set up four waywaypoints, spaced 200m apart, on your own field and time your UAV completing the course. Upload the data in the comments here. Best time on Sept 1 wins (I've got a prize this month--a new FunJet kit).

In the future, we'll add complexity and stricter standards to the trial, but this first one is easy:

1) Must complete the pattern as shown above, totally autonomously (go into auto mode before waypoint 1 and exit after you hit waypoint 1 again). The four points are arranged in a square, with 200m on a side (obviously the two diagonal paths are longer). Any aircraft/autopilot allowed. It doesn't matter how close to the waypoints you get, as long as you pass on the outside of them.

2) For this first one, altitude is not graded.

3) Fastest time to hit all points and return to 1 wins (one lap). Must provide GPS track with timestamps and on-board video. (If you don't have/can't afford a small onboard videocamera like the FlyCamOne 2, we'll let it go this time. But in the future: video or it didn't happen!)

4) Must also demonstrate that fun was had. Kids, picnics, silly hats, marching bands, something.

GPS tracks are best achieved with an onboard GPS datalogger, like the i-Blue 747 or smaller Sanav ML-7. But if you don't have one or don't want to add the weight, you can just capture the GPS track from your telemetry stream, although you'll have to figure out how to convert it to KML format to export to Google Earth (see below). If your Ground Control System has a built-in map+track function, a screen shot of that is fine, but it should be possible for people to check to confirm that your leg lengths are at least 200m.

Evidence data should include these four things:

1) Total time, along with aircraft and autopilot used. A photo of the aircraft would be nice.

2) Screen capture of path exported to Google Earth or an equivalent, annotated with waypoints and where autonomy began and ended. Here's a sample from Dean Goedde (waypoints and autonomy not marked):

3) GPS datalog file, any format

4) Onboard video, embedded from YouTube or Vimeo. [Not absolutely required but requested]

With funjet i reach 80 miles (ground speed). But was very windy! Like 30 mph! I was using a little screamer (super small and powerful).

Thats where a course like this minimizes the effects of wind on the overall time.

oooohhh its on

I get Ublox data through FTDI and UCenter is working fine, but when I connect shield to ArduPilot no LOCK after 5 Mins, How can I insert a break to examine Buffer data, I counted 104 bytes in the 3 ublox strings sent, but increasing buffer to104 didn't help. I want to sent a print statement after 1st good buffer fill and after lock.

ArduPilot may need to bank more than 60° to compensate for g forces from high speeds runs

Comment by Jordi Muñoz on July 31, 2009 at 12:40pm
Just make sure the baud speeds are the correct and you disabled all the unnecessary strings. The only way to know what going is printing out some values on the terminal. Are you able to lock using Ucenter?

Comment by Mark Colwell on July 31, 2009 at 12:57pm
Yes uCenter locks in 2min all day long 20 sec with hot start
I added print statements but it stall at wait_for_3D_fix

If I start up with NO short on 6 & 7 I get data out, but with no GPS stuff.

did you verify if the code is in 57600 bps? Because when i released it, i leave it in 38400 bps by default. =)

As for GPS datalog will the downlink stream of Paparazzi do (includes GPS data)? It's just really hard to convert the data into a KML. I can take a screenshot of the path with maps loaded from google earth to the GCS, though, but I'd prefer doing it with the more accurate local maps I have on my computer. I'll have video of the lap, however..

Well have to see how fast I can get my easyglider to go.. It's normally only 50kmh in cruise mode, though..

Sami: Any screenshot of the path on a map will do.
