I was finally able to complete a decent mission with my new build. I’m calling it the ArduBlade. Not sure how long I was out for sine it seems the log didn’t work but it was about 10 minutes. Ended up getting fouled in the lake weeds and had no steerage.

I created a few missions using q ground control. 2 survey patterns with a few lines, an octogon, and messed with the “go here” function for a while. The log only recorded one minute of data. I didn’t see any write error messages. What could be the cause of this? I’m recording on the Kakute F7 onboard SD card with a class 10 32GB micro SD card. See log below.

Communication issues YL128-rs422 and Sik radio

@cryobie wrote:

Hello dear people.

I am running some sensors that require rs422 connection. I want to relay these signals threw the Sik radio, but it will not act on signals from the rs422-converter. I have tested that the signal source and rs422 converters is functioning. I have also tested that the Sik is working on another signal source. The two just dont dig each other. Nothing gets threw. I have a feeling that maybe the Sik desires more voltage on the peaks than the converter gives. I have been trying to find som detailed specs on the ttl-parts (or chip) of the Sik, but cant find any. Does anyone know the threasholds? Or does this problem seem familiar to someone that has already solved it perhaps?

Best Regards

Hi,

I’ve installed MAVProxy both for Windows 10 and for WSL Ubuntu on Windows 10.

Everything works OK when I load module joystick in MAVProxy under Windows.

However, when I try to do the same under WSL Ubuntu, I receive an error message: MAVProxy.modules.mavproxy_joystick: Failed to find matching joystick.
Loaded module joystick

I have tried to satisfy the dependencies, including: pygame pyyaml joystick cuav pyserial

python -m MAVProxy.modules.mavproxy_joystick.findjoy does not find a joystick.

Would be grateful for any help!

Thanks,

Pogo

EDIT:

I spoke too soon. I’m also have problems getting the joystick to work in Windows 10 native:

MAVProxy.modules.mavproxy_joystick: Initializing pygame
MAVProxy.modules.mavproxy_joystick: Initializing commands
MAVProxy.modules.mavproxy_joystick: Loading joystick definitions

MAVProxy.modules.mavproxy_joystick: Found joystick (FrSky Taranis Joystick)
MAVProxy.modules.mavproxy_joystick: Failed to find matching joystick.

Does anyone know why this happens?

PXFmini beginner: No motor response. No RC calibration

@nich42 wrote:

Hi,
I am kind of new to this. I started putting the drone together about a year ago. Got it fully assembled then started configuring the brain. Using a rpi0 with PXFmini. Site Found here.

Everything went well until I tried to calibrate the radio. nothing. long story short, I was able to get it working one night. Seemed to be a combination of 2-3 problems. But did not record my steps and the next day I was back to square one.

Problem 1: RC calibration does not work. No response to inputs from controller. Exits with “bad input 1”. I’m using FS-i6x controller and have tried FS-iA10B and tgy-ia6. Bind worked instantly, no problems there.

Problem 2: No motor response to Arming. I wanted to check if it was just the RC or if there was another issue. I connected a xbox360 controller to my pc and enabled “joystick” in mission planner. I can arm the drone with a button press, but nothing from the motors. Note: since I have not gotten the RX working, I also have not calibrated the esc’s.

Notes: The battery display is always 0V and 0.0 A. I was able to change it once. Seems extremely finicky. Don’t know if this has anything to do with Problem 2.

If anyone has any advice in how to configure everything properly. Here are some previous threads opened for this.
http://forum.erlerobotics.com/t/unable-to-arm-drone
http://forum.erlerobotics.com/t/pxfmini-pi0-cpu-load-90

I tried working with erleRobotics team, but apparently they no longer make the PXFmini and have completely abandoned it.

Logging PID Data

No GPS VTOL transition

@Elmtree wrote:

Had a few successful flights as well as a maiden with my VTOL tricopter based on the VAS Ghost airframe:

There were some weird behaviors that I was curious about. This is using only gyroscope/accel and baro. There isn’t any sort of velocity reading. When I flip from qstab to FBWA it does a nice transition, but the voltage remains pretty low. When I flip from FBWA to acro the voltage bumps up for the same throttle level. I didn’t think to enable logging, but will next time.

My guess though is that it can’t determine that it’s going fast enough to full transition and just maintains the back motor until I switch to acro. Any other hypothesis?

Comparing a uBlox Zed-F9P GPS with a M8P without external corrections

$

@tridge wrote:

Google Photos
As the new uBlox Zed-F9P GPS is starting to become available I thought it would be worthwhile to do some side by side testing with the previous generation uBlox M8P. This testing is without external corrections, so both GPS modules are running as standalone GPS units.
The key change with the F9P is that it is dual-band when paired with a dual-band antenna. That allows is to estimate ionospheric corrections much more accurately than can be done with a single band GPS module like the M8P.

Test Setup

GPS modules used were:

The two modules were connected to the same Hex CubeBlack running ArduPilot, with the M8P GPS as GPS1 and the F9P as GPS2.
Note that the external antenna, long antenna cable and magnetic base of the F9P setup make it impractical for most small aircraft, but modules with integrated multi-band patch antennas are now starting to become available. The first of those is here:

I don’t have one of those yet (it wasn’t available when I ordered the Drotek unit), so I tested with the one I had. I look forward to other vendors releasing more F9P based GPS modules.

Scenarios

Three scenarios were tested

  • a extremely poor location looking out the window of a house with a metal roof, looking over another house. Clear view of the sky is only available over about 20 degrees vertically. This represents extreme multi-pathing.
  • a good location with clear sky view
  • a medium location with medium density tree cover and a nearby house

All 3 locations were in Canberra, Australia.

Even though these GPS modules are capable of RTK fixes a source of corrections was not supplied. The aim of these tests was to see if the dual band and improved processing in the F9P would produce less variance in position and altitude without external corrections.

Location 1:

The first location was with extreme multi-pathing. The antennas were up against a window in a house with a metal roof and metal eaves, looking over another house.

First we show the altitude reading in meters over a 12 hour period:

And now the horizontal error in meters:

Location 2:

This location was at the CMAC flying field, with clear view of the sky in all directions. Altitude in meters over 3 hours:

and horizontal error in meters:

Location 3

This location was in the backyard of my house, with medium density tree cover. Altitude error in meters over 3 hours:

and horizontal error in meters:

Conclusion

The F9P with a dual-band antenna provides a very large reduction in both altitude drift and horizontal drift over a single band M8P. Altitude drift is still high enough with the F9P to make using a rangefinder or other altitude source for landing worthwhile, but mission accuracy should be a lot better.
The F9P reported approximately twice as many satellites as the M8P in each situation, with up to 30 satellites tracked with a clear view of the sky. It seems likely that it was the same satellites as the M8P with each reported once for each band (L1 and L2).

Hello,

I want to build a 2nd additional ground station, which only listens to the transmitted data from the drone but is not coupled to it, that’s what the first ground station is for.

Does that work somehow?

Thanks in advance!

Pixhawk digital airspeed sensor + external compass on I2C Splitter

@Tofandel wrote:

Hello,

I just finished my pixhawk installation on a Volantex Ranger EX 757-3

I have an external gps + compass module which works perfectly when plugged in the i2c port directly

I decided to add a digital airspeed sensor so I’m now using an I2C splitter

But with this configuration the external compass is not detected anymore, any idea why it’s not working?

I have the latest arduplane stable release (3.9.8 on ChibiOS)

Also I’m using Qgroundcontrol for the configuration and I tried plugging the airspeed sensor only without splitter and setting the ARSPD_PIN to 65 but I don’t see any data related to airspeed on the interface or any new sensor, how can I check that it’s working?

Using rudders for YAW on HeliQuad

@Max_Drougge wrote:

Hello.
I’m building quite a large scale HeliQuad based on the ardupilot software. Previously I’ve tried the “standard” HeliQuad firmware. It does fly with it but the YAW is problematic. The YAW is way too agile even when tuned down. What I would like is to have the heliquad software but extracting the YAW output to a seperate channel to input it to rudders. The lift power of the heliquad would be increased as it is not needed to “take” lift from the rotors for YAW maneuvers.

What do you people think? Is it possible to do this?
