[Paparazzi-devel] Encoder Problems

[Adam Amos]

Hi All,

I am experiencing a strange problem with two of my PPM encoders.

They appear to be operating properly (3Hz LED) however I am unable to see
the PPM signals in the GCS and I am also unable to change the failsafe value
(fails to upload successfully). I have tried with multiple receivers (Corona
2.4Ghz and 36Mhz) but to no avail. 

Has anybody encountered this before?

Hi,
I4m testing the paparazzi system for small UAV for University purposes. 
I4m a newbie in Linux as well as in Papaprazzi.
I use a Easy Glider plane for test flights.
Today I was first time in Air after testing everything on the ground. 
The gain parameters seemed to be a little high, but everything else worked
fine.
I walked around the waypoints with the plane to see what happens again
everything fine.
I also did a very accurate test of the RC transmitter range.
After launching the plane in manual mode I got a short climb flight and
everything worked fine again.
After reaching 50m manual control was not possible anymore and the plane
crashed.
When I looked at the ground station, the only message I got was that the
paparazzi went into Kill mode (nice expression) which, in my opinion means
that the plane stops throttle and tries to navigate home.
No other Mistake message appeared.
Does a possibility exist to switch this "safety" feature off?
When I fly manually, I don4t want to do the autopilot anything and never
ever.

Thanks for your help

Christian

Hallo Christian,

the kill mode is meant to turn off the engine to have battery power left for
a landing or keep the aircraft from flying far away. Kill mode does not
affect navigation. If there is still a RC connection the manual mode
overrides kill mode as manual mode always overstrikes the autopilot. There
are three ways to get into kill mode:

- pressing the red 'kill' button in the gcs
- aircraft is not able to come back in HOME mode (flying further than
KILL_MODE_DISTANCE)
- battery level is low (voltage below LOW_BATTERY)

Kill mode can not be turned off but you can set both values in the airframe
file so that it would never be triggered. Could you provide the telemetry
log files for a closer look?

Martin

I confirm what Martin says : kill mode has no effect while in manual -
if the aircraft became unresponsive in manual this is due to something
else. Now getting the kill mode message probably means that your
battery went low and if it went low enough it might have crashed the
autopilot.

Hi Christian,

Normally at the start of a session, the GCS would display "Wait GPS", then
"Geo init" and "Holding point".
When at Holding point the throttle is off for safety reasons and the "Kill
mode" message is displayed.
When you click on the "Launch" button, the throttle is enabled and "Kill
mode" is disabled.

So, probably you did not click on the Launch button and saw the Kill mode
message.

In manual mode, the autopilot is not activated. The R/C signals are simply
passed through from the R/C receiver to the servos.

You should read more documentation on the Wiki (http://paparazzi.enac.fr)
particularly the "Getting Started" section, the GCS page, as well as reading
the User's Manual.

Cheers, Mark
