Re: [Paparazzi-devel] Low cost autopilots for paparazzi

[Prof. Dr.-Ing. Heinrich Warmers]

Hi Michal,
a problem with the Paparazzi project  is that the hardware is expensive by the low count  of  units  for example for  many students and hobbyists.
The special hardware like Krooz, Apogee etc. is good but not available in many countries or shops and make also
a determination between mutirotor or normal wings aircraft
For example the production  of our one autopilot HBmini  the self cost of  manufacturing  a set of 10 units is about 2500 Euros.
The fix cost of a production run is about 1000 Euros in Germany .
The construction  of a prototype by hand need about 40h.

The second idea is to use the same cheap hardware for simple software like  MultiWii and a more complex like Paparazzi.
This gives the chance that a hobbyists starts with the simple software and can chance to Paparazzi to a second without new hardware.
The work for the implementation is only  the addition of  a new make system and directories.

Regards

Heinrich

Hello Heinrich,

do I understand correctly that you want to port paparazzi onto an existing hardware? I noticed that recently lot of new APs came out (Krooz, Apogee) and the community is working on those. Just a suggestion - maybe it would be better to first finish and properly test those boards (so they can be considered airworthy) before moving to new hardware (which should be way easier with proven drivers)?

With kind regards
Michal

Hi,
i want to start a discussion for low cost STM3 autopilots to use with paparazzi
I have flown a low cost Multikopter  with the following autopilot with the STM32f103 (M3 with 48 pins 128kB EPROM 20kB RAM):

 http://flyduino.net/Multikopter-FC_2  cost  47 Euro compatible with
 
http://abusemark.com/store/index.php?main_page=product_info&products_id=30 
(cost 49,50 Euro) compatible with
 
http://abusemark.com/store/index.php?main_page=product_info&products_id=45 
( Cost 18,50 Euro without magnet and baron sensor).

The multirotor has the same performance, like my paparazzi multirotor.
The software is a 32-bit MultiWii port.
The hardware is full Paparazzi computable.
The board has a USB connection and sensors of the sate of the art.

It seems to be simple to port paparazzi on this hardware. The only restriction is the 128KB EPROM space.

Is same one of the Paparazzi team willing to work with me to port paparazzi on this hardware?

Next time STM offer a processor with 265KB EPROM and 64 KB RAM in the same housing with the f4 CPU (floating point unit, cost about 10 Euros).

I am locking for answers

Heinrich
