S&R challenge dates

Hi Mick,

Can you confirm that the open S&R challenge is indeed on this year? It was previously announced that it wasn't on till next year, but the new 2011 site lists it as being on 1st to 4th October 2011. Is that a typo, or is it really on this year?

hmm, I suspect its a typo, as the detailed rules list the date as 1-4 Oct 2012, although the registration closes in July 2011, and the first deliverable is 27 July 2011.

Maybe you could fix the website to avoid confusion?

Cheers, Tridge

Thats a typo.
There's a couple of other minor errors in the S&R rules document as well.
I'm sure they will be cleared up in future versions

another clarification - NMEA

Hi Mick,

Section 5.15 says "either ..... and". Can you clarify if both situational awareness methods are needed? We will probably have both anyway, but it would be good to know if both are required in the rules.
For the NMEA serial link, what type of serial connector do you want, and what baud rate? Would a reconstructed NMEA stream from another GPS format transmitted to the GCS be OK? We will probably be transmitting GPS from our plane to the ground station using MAVLink, which contains all the information needed to construct a NMEA stream, but we would need to construct that stream on the ground, rather than having it come directly from the plane.

Cheers, Tridge

PS: We did our first flight test with full image capture, onboard computer and automated search pattern today. I'm glad the rules didn't change too much!
PPS: Thanks for all the effort that goes into running this challenge!

Interesting.....official acknowledgment that the "Kingaroy Triangle" actually exists.

In regards to:
"The airspace within the mission boundary will be specially allocated by CASA for the event and teams must not fly below 200ft (excluding takeoff and landing at the airport)."

Are we allowed to go below 200ft to drop the package off if our craft supports VTOL maneuveures?

Also can we submit and then resubmit Deliverable 1 if it gets rejected for whatever reason? (Provided we change it to meet the problems outlined in the rejection)

open development in OBC teams?

I'm curious what other teams are planning with regard to openly discussing their design in the lead up to the 2012 S&R challenge. Out team (CanberraUAV) took a decision early on to be totally open. So all of our code is up for anyone to see, and our discussions are all publicly available. Our website is still being put together so right now it is not always easy to find everything we're doing, but that will improve as Steve gets used to managing the Drupal website.
I've noticed that some teams have really nice development blogs (the rescue robotics and project andromeda ones are excellent!), and I'm hoping other teams might do the same.
There is an interesting overlap between this openness and the new "statement of originality" provision in the 2011/2012 rules. Our team takes the attitude that it is fine for other teams to get ideas from us, as long as they acknowledge the ideas in their entry. We will do the same for ideas we get from other teams. That is essentially what the new 6.2.1 rules are saying I think.
The ultimate goal of the outback challenge is to advance the state of the art in amateur UAV development, especially for rescue tasks. I think that goal is best served by the teams being as open as possible.
For our own team, while our website is still being developed here are some links to what we are up to:

Cheers Andrew, I think it is very much in the spirit of the competition to share experiences around and have a good time making things work rather than re-inventing the wheel.

Well how much open'ness do you want ?

However for the airframe and other challenge rationales, IMHO the discussion is better left for after the event. This way we will not all copycat eachother and some more interesting ideas and real solutions will surface.

Clarification of Failsafe RX

Hi Mick
While you are checking those other things out, can you also look into the failsafe receiver. Page 13 of the Airborne Delivery rules says 'failsafe values' (plural) and page 14 says 'servo positions' (plural again) but then it refers to only one item which is the throttle - ie: 'to simply close the throttle'. Traditionally in this competition, failsafe was on all channels but this sounds more like what Spektrum called 'Smartsafe' which is throttle off and all other channels last good signal.

With my DX7 transmitter and AR7000 receiver there are two different failsafes, [1] and [2].
With my DX7 transmitter and AR500 receiver I get failsafe [1] only.
I discovered this by reading a friend’s JR manual, so different radios from the spectrum/JR stable seem to have different arrangements.
[1] is achieved by removing the binding plug from the receiver after the transmitter is turned on. The motor goes to the setting as per transmitter on binding, other surfaces as they were before the failure.
[2] is achieved by removing the binding plug before the transmitter is turned on.
All settings go to as they were set on the transmitter during binding.

So, to satisfy the rules requirements, with some radios you can use the radio failsafe settings. With others you will have to build hardware to accomplish this.

Jack.
