Looking for more pointers to help sort out my issues

Posted by Jeremy on May 12, 2010 at 4:28pm
First sorry for the long post and read, just trying to offer as much info as I can in hopes to help sort out my issue. Thanks in advance for any help and or suggestions.

So far I have tried the following AP versions - 2.5.4 and 2.6
I sent my entire setup to Chris to check out and what he came up with was I had it set in the incorrect Radio Mode I had 0 but he found 1 worked with his radio and the rest of my setup. Once getting it home and setting things back up I kept the Radio Mode 1 setting and noticed worse results for me with my radio. Results of the difference for the modes is posted below. I think Mode 0 is correct according to the results. But then why did Chris get it to work with his radio but everything else on Mode 1? Though I get more consistent results using Mode 0 I seem to get failsafe errors happening.

For the rest of this post it will be with me using V2.6 since the issue exists on both versions for me.

Here are my results for the following tests so you can see the output of everything.

For this test Y seems to be the only one effected when moving my hands around the sensors.

What I noticed during both of these tests since I did not want to paste endless results when moving my hands by the sensors there is only really a noticeable difference on A2

Again with me not touching anything on the radio so to me it appears the radio should be run in mode 0 and not mode 1.

The above is all in manual mode everything sitting level and moving nothing my sensors are showing that the roll and pitch is changing. When in other modes as you will see below it bounces around even more again with not moving anything and not passing anything by the sensors.

When I have V2.6 loaded what happens is everything on Manual mode appears to be ok switching to either stabilize or fly by wire a the servos begin madly twitching. Which to me seems to be following along with the pitch and roll not being able to hold a steady number. I have tried Radio Mode 0 and 1 for me 1 seems to give me worse results. More of the "twitching" though I never see any failsafe warnings. in Mode 0 I occasionally will see that failsafe has failed.

I have previously tried eliminating the ESC from the equation with same results. I have also gone through basically everything but using a new radio. Everything for me gives me the same results of the "twitching" I do not understand though why the sensors can not hold a steady reading when sitting still, level and having nothing moving around it.

What I did to test the board:
1. Turn on Radio
2. plug in FTDI
3. plug in battery through the ESC
4. Allow to get GPS
5. COM says its ready
6. results above start

My equipment:
Futaba 7c 2.4ghz
futaba RX r617fs
Exceed ESC
HS81 servos
EM406 GPS
Ardupilot board
Ardupilot shield V2
Ardupilot XYZ sensors

Initially when the stuff came back when it was booting I was trying to calibrate the servos though I did not have that set. Was told by Chris that it could be an issue so I stopped doing that as the board was booting and calibrating.

I have re verified that my settings for the 7c match what is listed in the manual on how to set it. And done exactly as the steps state.

To me and this is my VERY uneducated guess that the issue lies in the XYZ sensors, reason I think this is because they do not hold steady when the full ArduPilot V2.6 is uploaded the pitch and roll constantly bounce around and I started to watch the servos more closely and the "twitching" seems to be the servos quickly trying to react to the sensors bouncing around so much. I have tried both indoor and out which appear to give me the same results.

I have also tried uploading with nothing but a 4.8v battery hooked up while uploading the code as well as just the GPS disconnected, About every possible way I can figure out.

Results from outdoors is Mode 1 gives me the least "twitch" indoors Mode 0 gives me the least "twitch"

Also when i turn off my controller it does not seem to effect anything on Mode 0 but on Mode 1 it seems to act normally it seems to be trying to take the plane back.

I will post any other additional info needed or anything else for better helping out.

    Well after a long trip to town to try a radio at a hobby shop there trying a 7c (only one they would let me try) I had the same results as the radio I have. I copied the settings exactly, so must be an issue with my radio. I must not be understanding the manual properly in setting up the TX, I go through step by step as listed and adding the values the way they are shown and not working properly for me.

    It is not doing it in manual outdoors. but does it for Mode 1 and Mode 0. Manual seems to be OK on both Modes outdoors. Though not indoors.

    Since there was a difference in my chipset for the RX could the settings I am using from the manual possible not be correct for the 7c since the RX is different?
  • Jeremy May 12, 2010 at 5:46pm
    I would say on average maybe 5 degrees or so but I would say every 20-60 seconds the rudder servo max's to both directions so hard you can hear the servo click to each extreme.

    Should I just take the change to Mode 1 and take it up in the air and stop worrying about what its doing on the ground?

    A little twitching is perfectly normal; a lot is not. How many degrees are they moving, on average?
