Help with reading log files from MissionPLanner

Hi!
I made my first successfull take off today. F550 hexacopter, ublox GPS and Devo7 transmitter. The hexa hoovered like no drone I ever flown before. Marvelous and beautiful! I flew a few meters and then let it self stabilize two-three meters above ground. Then the whole copter tilted and started flying away. I panicked and pushed "hold pos" but nothing happened for two seconds so I increased the panic and pressed "return to home" and two seconds later the whole thing made cartwheels over an old dusty road and collapsed in a heap of parts. (I think everything except two arms and the main board is salvagable)

Can anyone help me with the log files and see what went wrong? The only thing I can decipher is DCM bad heading, and that dissapears after a few seconds. The copter drifting off and then bolting away into the road was (as far as I can tell) in direct opposite of remote commands.

Thanks in advance!

Coding for a plane with VTOL/

Hi,

I am trying to build the code for a coaxial bicopter-cum-plane hybrid firmware. It takes off and lands like a copter, and once it hits a specific velocity it flies like a plane.

I was wondering, if its possible to switch between arduplane and arducopter firmwares in mid flight, given a preset condition is met. Will it be possible to do it on a single erle brain 2? Do I need to use ROS?

Any thoughts on this would be appreciated!

Hi,
Since new users cannot have more than 4 posts on the same topic, which was Tiltrotor with Tridge, I am attempting to create a new post for other new users to post on until they are no longer considered "new users".

It's a bit limiting but we always find a way to work around the limitations.

Good News... funding on the way

Good News, I just got word that our proposal “Unmanned Automated Ocean Survey Platform”
Will most likely be funded in full. Like most my other boats, it uses APM/Pixhawk and mission planner.
This craft will utilize 4 x 300 watt solar panels and golf cart batteries for possible 24
hour operation.

The boat itself is a Prindle 18-2 with lots of flotation and room in the hulls for batteries… (334 lbs)
My other boats ran about 100 watts/knot at 3 knots… this one should be far better…

Before I get the funding I starting developing a long range monitoring system using uno and 24bit a/d board.

This system will transmit via vhf radio at 1200 baud, position, volts and amps of everything every 10 seconds

The range of this system will be 10 miles to start but can be increased easily.
I will keep the community updated because you guys have great ideas quite often

QuadPlane All Ready to Go But Need Some Advice Please

@jacques_eloff wrote:

My Quadplane is all ready to go but I have 2 questions I’m hoping someone can help me with. I have done 3 fixed wing Pixhawk planes, so I'm comfortable with Plane firmware, but my multirotor experience is limited to DJI products thus far.

Firstly, I’m having trouble calibrating the ESCs. I am on firmware ver 3.5.3 (not going with 3.6.0 just yet) so I have to go with the “Old Calibration Procedure” described here: http://ardupilot.org/plane/docs/quadplane-esc-calibration.html. The problem is with step 8 – ie, disarming the ESCs after they have registered the max PWM. I have set ARMING_RUDDER to 2 to allow left rudder to disarm but the delay means that I cannot execute this in the required time. I am using T-Motor Air ESCs and (like most ESCs) they move onto the next parameter setting (timing in this case) 3 secs after the calibration setting (“beep-beep”). However, I think I may have managed calibrate the ESCs by switching to manual mode just after the “beep-beep” because this caused the ESCs to exit the programming cycle. But I don’t know for sure. Surely it would be easier just to link my ESCs in a daisy chain with Y-leads and calibrate them that way?

Secondly, reading through APM copter, it says that throttle minimum for 15secs will disarm the motors, but this does not seem to happen with Quadplane – they just carry on spinning until I disarm with left rudder or switch to manual mode. Not really an issue, though.

Thanks,
Jacques

Raspberry Pi 3 connecting to Pixhawk

I am following the manual from here to the letter:

http://ardupilot.org/dev/docs/raspberry-pi-via-mavlink.html

And after running the script I end up waiting for the heartbeat and they do not connect.

I know to change the starting parameter since the RPi3 has changed the ttyAMA0 for ttyS0 and I checked the baud rate and have set both the pixhawk to 115200 on serial 1 and 2.

My starting line is as follows:

mavproxy.py –master=/dev/ttyS0 –baudrate 115200 –aircraft MyCopter

Any ideas whats wrong?

Hello,

I search the parameter for autotune.
I miss GCS_PID_MASK.
What is the parameter for it?

Additional:
If I use AUTOTUNE as special mode in Channel6, it work.
If I use AUTOTUNE as flight-mode it dosn't work?

Hi,
i´m running a pixhawk lite on a tbs discovery clone.
Running the quad in standard modes (stabilize, altitude hold, loiter, etc) I can download the logfiles, everything is fine.
When uploading a mission via 3dr radio and flying it all logfiles on the pixhawk are gone but also no new one will be created on the FC. The quad runs the mission without problems but there is no logfile. :frowning:
I`ve allready checked the configuration, all parameters seemed to be like they were befor the mission, no changes.
Also I checked the DOCs for further information but couldn´t find any matching item.
Anybody an idea ?

Need help with firmware modification for my own use

@charles_linquist wrote:

I would like to modify the APM arducopter firmware for my own use. This is for a quadcopter, and I'm running the APM 2.6 version.

I need to add a 5th servo output that is the average of the PWM values of servos 1-4. As I look into AP_MotorsSingle.cpp, I see some possibilities, but It also looks like I would have to modify things like get_motor_mask as well. I'm certain their are other things that would need to change that aren't immediately apparent.

The code is complicated enough that I don't feel comfortable making this modification without consulting someone who knows a lot more about it than myself.

I should state that I have successfully modified a few lines to smooth out the current measurements, and to add a battery ESR 'correction factor' (adds ESR * Amps to the displayed battery voltage), but this new "average output" is beyond my capabilities.

Would someone be willing to help me?

First Testing AC3.4 RC1

@Pomaroli wrote:

Hi.
attached 3 logs from today's fly session with my Hexaracer.

Logs
1. Autotune Roll and Pitch
2. Autotune yaw
3. Flying around with the new settings at the begin it was ok but it became more more instable, probably related to the GPS Modul ? (see below PXGPS)

Impressions
- In my opinion AC3.4 has an improved 3D handling which is not fully capable yet or my copter has some issue i don't have sorted out now. (See below PXGPS modul?)
- Autotune results are very different from before with AC3.3.3.

i'm trying out also a new GPS modul from China named PXGPS with ublox 7, which is very small and lightweight.
i had really problems with the magnetic interferences (magfield) you will find in all 3 logs some issues which are related. Is there a better Setup for this GPS modul ?

I'm in a hurry to get a Pixhawk and all of the online stores local to me are out of stock. HK has a clone but I'm not a big fan of clones as I'm a design/engineer and it would piss me off if someone copied my products.
What everyones thoughts on the HK clones, good/bad.
I could bit the bullet and purchase from 3DR and pay the same price as the pixhawk for the shipping?
Cheers,

@vfcgps1688 wrote:

Now, this has been seen/done recently for an in field implementation (reference here), and myself as an AG GPS technician would love to see if we can create long range auotnomous systems. Starting slow with either full implementation or hybrid cabling into my technology (uses the NMEA from my GPS receiver, tying into my PWM valving, companion computer, etc). Any feedback would be appreciated.

We already have operator present autopilot with full in field turning on our top models. this would be more "to position" and override to keep within a determined boundary. We are capable of either running submeter or sub-inch horizontal positioning, and have controllers with either roll and yaw or pitch, roll and yaw. and we either have proprietary CAN moniotrs or a new Android based modular Tablet interface. Thanks in advance :slight_smile:

Autonomous side scan survey kayak

Been lurking in the background for a while now but I think I'm about ready to start work on my first build. What I'm envisioning is a dual trolling motor setup (skid steer) set on a 16 ft old town look 160T kayak. Once the autonomy is worked out I eventually want to incorporate a hummingbird or lowrance side scan unit on a teather to collect high resolution bathymetry and side scan data here in the Puget sound (Washington state) . I will be using the 16ft tandem So that I can "ride along" until I'm comfortable with the autopilot taking complete control at which point I will move the whole package to a smaller hull (single seat kayak more than likely). As I'm just getting started I would love to hear any suggestions or look at any relevant prior posts.

I'm having some trouble getting to know my Radiolink AT9 Controller, specifically the switches. the 3 Position SwC gives me three flight modes, but none of the other switches register anything in APM planner when selected. The controller has 8 switches -- it would be great if I could assign a flight mode to each one, but it isn't clear how to do this.

I am a fairly handy guy. but find myself with wires and plugs that I don't know where everything goes and there was no manual with it.
Can anyone direct me to a manual, video or anything that can can help me get all these pieces into a working unit? Unfortunately I don't know anyone nearby who could help. I can solder, cut and screw etc....just need to know what goes where.

Thanks in advance for any help,
