Hello together,
I'm an engineering student from Lyon who got currently involved in a
project of building an UAV. We took over the project from another group,
which already put some work in this. Right now, some hardware was
already bought:
- a microcontroller (PIC16F876A, 20Mhz)
- a receiver/transmitter set (ARM-U8, frequence 868Mhz)
- a GPS chip (EM406A)
- a quartz (20Mhz)
- a gyroscope (IDG 500Dual)
- a batterie
- some cables
(As we think that the receiver/transmitter doesn't work with Paparazzi
(?), we are probably going to change them.)
Our goal is to buy a Twinstar II, build the necessairy card, wire
everything together and than control the drone from the ground via
Paparazzi.
Now as I have described the setting, do you guys think this is possible?
I'm not quite sure about the true function and work done by Paparazzi;
am I correct when I say:
* Paparazzi does all the aerodynamics calculation
* It than sends the current speed and direction orders to the plane
* The card on the plane needs to interpretate the orders and do the
actual adjustments of control signals / power levels
* The plane itself sends back GPS / gyroscop signals to Paparazzi
So our main work would come down to the above described interpretation
of orders. Is our microcontroller sufficient for this?
I'm sorry for this quite lengthly explanation, but I tried to keep it
short anyways :-). When reading the Paparazzi Wiki, talking to the old
group and our tutor, we got a lot of different infos about Paparazzi's
mode of operation + capabilities, so we thought it would be the best to
ask you guys directly.
Best regards,

Hi Christian,
None of your current hardware will be much use I'm afraid.
You need the autopilot unit itself which is called a Tiny. This goes in
the aircraft.
http://paparazzi.enac.fr/wiki/Tiny_v2#Architecture
You can't stabilise a UAV via the ground, there is too much latency.
The paparazzi board (Tiny) does all the work, the ground station simply
displays what is going on and allows changing high level flight
parameters (current waypoint etc).
If this is your first UAV project, forget the gyro - Paparazzi
traditionally uses infra-red level sensors, which are described on the
wiki.
Have any of you got experience with model aircraft? You will need
someone who is competent at flying model aircraft. Your Twinstar should
be fine. You almost certainly do not want to build your own Tiny board
- I would highly recommend purchasing from one of the suppliers, listed
on the wiki.
An example of everything you need is here (I'm not promoting this
particular supplier, they are just the only one I'm currently aware of
with a photo of all the stuff you need!):
https://mini.ppzuav.com/osc/product_info.php?cPath=2&products_id=68&osCsid=jug5m75orjn3rvq182qhmq8vfaquggjc
Also, read getting started on the wiki:
http://paparazzi.enac.fr/wiki/Getting_Started
I would recommend maybe reading through the wiki a couple of times, and
then trying to run a simulation as described in the getting started
section just to see how everything fits together.
All that said, welcome to the mailing list and to the Paparazzi community!

Hi Gareth,
thanks for your reply, it cleared up some things. I managed to get the
simulation running in Paparazzi and I read a lot on the wiki (even
though i didn't understand everything).
So, for a real flight, one would - after configuring Paparazzi - compile
the necessary code and flash the board with it, in order to enable the
UAV to do all the algorithmic work?
Well, if that is how it's done, than one would normally need to use the
transmitters, the board and everything else supported by Paparazzi (as
suggested by you). But as our task is not to just assemble an UAV - we
need to do some engineering work - the only possibility would be to
build an own Tiny2 board. Is this correct??
Thanks for the warm welcome!

Christian

Or you could run Paparazzi as a Linux-Userland process and
write the code to support your specific sensors, actors and communication.

By doing this, we still would have to get a Tiny2 board, which seems to
be our biggest problem. Trading off between and buying new components
and writing Linux driver code, we are probably better off with the new
components (given time as a factor) ...

Marcus's suggestion is a good one if you have a good level of
familiarity with Linux and embedded systems.
Assembling your own tiny is not really 'engineering' (it's just
difficult to do well) - is this an undergraduate group project, and if
so is there a requirement to have an element of novelty in the design?
Assembling a UAV is a much more difficult task than people always
assume! I've seen 10-20 undergrad groups who in the past have tried to
build a Paparazzi-powered UAV and not one of them actually got anything
working autonomously.
Paparazzi do not 'support' parts - we just have a list of stuff that we
know works! There are a lot of design decisions you will have to make
alone.
The makeup of your group will also influence this - if there are more
'structures' than 'systems' guys, you might want to think about changing
the airframe design instead?

Yeah, this is an undergraduate group project, but no, novelty is not a
requirement. The thing is, the project was plannend for serveral
consecutive groups, and we are now about the third taking over the work
of the over two groups. That's why already some stuff is bought, and
we'd like to build up on their work. But honestly, right now I don't see
how, as the board they have constructed can not perform the calculations
and is probably not compatible with Paparazzi. I will talk with the
others and our tutor, and maybe we need to redefine the project task.

Hi Christian,
I personally would recommend purchasing a pre-made set of everything if
your tutor will allow it. Getting everything integrated and working
will be challenge enough if you've never worked with UAV's before.
It's good you've got this far. It sounds like the previous group did
the typical undergrad thing of "autopilots are easy, we'll write our
own". 7 months later, with nothing but a poorly written NMEA parser and
a servo that wiggles, autopilots suddenly don't seem so easy.
The tx/rx pair you have will possibly work. The PIC is worth pence (or
cents, in your case). The gyro is nice, and a later project could
integrate it into paparazzi - but for now, just worry about getting the
thing flying.
You also need to organize somewhere to fly, and someone to fly it.

Hi Gareth,
you are probably right. I will discuss this option tomorrow in detail
with the others.
We got a stadium here at the university, which should serve nicely as
place to fly. Getting a pilot is something we are currently working on,
but I'm sure we'll find someone.

Christian,
Please email ppzuav at gmail dot com with the details of your project. They
select teams like yours several times a year to support with donations. If you
do not mind putting a sponsor logo on the plane they can donate an autopilot
and cables to get you flying.
It is their way of giving back to the community by helping new student projects
to get flying who would otherwise not be able to so.
As mentioned it is a challenge already just taking assembled parts and doing
the integration. The good news is the comfort you can take that everyone who
starts Paparazzi eventually flies successfully if they persist and ask for help
when they need it.
Best regards,
David Conger

Hi,
we just had the meeting with our tutor and decided to get a Tiny2
autopilot! This seems to be a very good solution, because we could
hardly exploit any of the previously done work.
Furthermore, we are quite surprised that a sponsoring could be possible
and are happily giving that a chance. So thanks all for the advices and
help!! It's really appreciated.
