How do i choose battery for my drone?
@louistwiice wrote:
Hello guys!
I’m a new beginner in uav field. My project is to build a Drone for inpection in aviation. I would like to know how to choose a good battery for my drone. I’ve seen many videos in which people explain how to choose it but i’m not sure to understand it all.
So here is my configuration
type of vehicle: quadcopter (4 motors)
flight controler: pixhawk 2.4.8
motor + propeller: cibra 2206 2100kv + HQ 6030
telemetry: rfd 900 for long range
What do i need for my project?
time flight: 20mn minimum, not less
my questions are:
1- what battery feature do i need? (If you could detail how do you choose it, it would be great
)
2- Do i need to change my type of vehicle? Because, i’m not sure a quadcoter can handle that. So do i need to take 6 motors instead of 4?
thank you very much

What happenned to relays?
@GoFast124 wrote:
I need to have a relay switched using my transmitter. The wiki doesnt show how to do this with ardupilot 3.9. I think i have managed to set up aux5 as a relay output but how do i map an rc channel to control the relay?

RTL at 1m/s, why?
@Steve79 wrote:
hi all,
in a large quad with PH2.1 and Arducopter 3.7-dev, everything was working as expected until yesterday, when i turned RTL on the TX and it switched correctly, but speed was a slow 1m/s.
Previous flight, i used to have a solid speed, i can’t remember exact speed, maybe 6m/s.
Then i landed manually and checked RTL_SPEED, it was = 0. I put 1000 (which should be 10m/s), flow again, switched to RTL and again it was coming back at 1m/s.
What can i do/check?

Use joystick to move the camera
@jager wrote:
Hi, i have installed a SITL simulator on Linux with FilghtGear following the guide and it works.
Now, i had an idea to move the camera, like a gimbal, while i’m fliyng. What i can do?
For example, with a stick of the joystick, i want to zoom in/out or move up/down/left/right with the camera on flightgear.
It’s possible? I have to intercept from MavProxy the channel of that stick and then use the telnet command of flightgear to move the camera? There is a simpler way?
Thank you

RTL problem param list
@esy.j wrote:
Hello All,
I flew yesterday with my copter and I came up with a very interesting question for my self!!
when my copter was about 0.5m above the ground ,I noticed the battery is low , so I wanted to land but what happened was , the mode changed to RTL , since it was selected for the fail safe mode to do so.
but What it got my attention was that the copter was going higher and higher although I put the RTL_ALT to 50 cm which is 0.5m so it needed not to higher than this ALT. am I right ?I checked in the param list And I saw the RTL-ALT can be choosen from 0 to 8000 cm . and I had chosen this to be 50 cm before.
now I saw in the webpage of ardupilot the range is showing a number between 200 to 8000cm.
why these two number in param list and ardupilot page is different ? which one is correct ?RTL_ALT: RTL Altitude
Range Increment Units 200 - 8000 1 centimeters

Question about Pixhawk 4 Processing Limitations
@dtmcnamara wrote:
Hey everyone, first post here but that is after many months of reading.
Over the last few years the company I work for has been wanting to get away from the DJI ecosystem and start to assemble our own drone for industrial applications. With the most recent political issues between the US and China and the bans actually starting to go into affect I have been given the green light to start to order parts and electronics to create a v0.1 test drone so we can start down the long road of R&D.
Upon looking into all the optional hardware that can be added I constantly see everything is being ported through some of the same connectors on the Pixhawk 4 board. I understand with the I2C bus I will need to set each device with a unique address and use a splitter but what about processing power and reaching a limit for things to operate correctly? At what point do I need to start to worry about there not being enough CPU power and need to start to look into a companion computer to assist in things? Below if a list of the current items we will be needing
Gimbal
Camera trigger
Dual GPS
RPLIDAR
Telemetry Radio
IR-Lock precision landing sensor
PX4FLOW camera
FPV camera
Retractable landing gearsI’m definitely a noob when it comes to drones so please excuse me if this is a basic question.
Thanks

Pimavlink: extract camera feedback time from log file
@ardupilot.td wrote:
Hi,
I want to extract the extact (subsecond) time of the camera feedback event from the log file with the help of Python/pimavlink.
I have managed to load the binary file and filter it for the cam messages. But within the message I could not find the precise time of the event.
Any hints how I can extract the time from the DFReader object?

Unable to prearm because of compass calibration failures
@Peter_Weichhart wrote:
I think I tried nearly everything what I could found in this forum:
I deactivated compass 2 (no result)
I deactivated compass 3 (no result)
I deactivated compass 2+3 (no results)
I calibrated in both methods: Live and onboard calibration (both successful)Because of my frustrations I set ARMING_CHECK to Value 15866 all checks but excluding compass)
But I haven’t expected the result: Now I don’t get a message anymore “Compass Calibration” at Fright Data, but the behavior of the flight controller is still the same: It blinks green, beep every +/- 2 seconds (for hours) and still no arming.
I wonder if I do something wrong, or misunderstand something or is there a bug?
I hope somebody can help! Thanks a lot and greetings from Namibia

Problem connecting UGCS to flight control EMLID EDGE
@rcdevil wrote:
I’ve been trying to connect EMLID Edge Flight Controller and UGCS Pro for days, have made some settings in the file “ardupilot_vsm.conf” but without success.
You use the wireless modules of EMLID that are sold together in a set with the Flight Controller:
https://emlid.com/edge/
The connection to the software QGroundControl works, but unfortunately not to UGCS.
Could you possibly post a screenshot of the file “ardupilot_vsm.conf”?Thank you

Nasty crash, please help with interpreting the logs
@netzero2015 wrote:
Unfortunately today I pretty much destroyed my hexa in a flyaway that I am struggling to understand from the logs. The compass on the Pixhawk is bad after the crash and I suspect I had a bad contact on the GPS i2c connector. The drone flied well and landed 2 times, one in RTL, in two short tests of a few minutes, then on a third take off I went a bit higher in alt and noted some strange twitching (could not see well as the Sun was in the same angle as the drone), decided to lower the alt (and probably land immediately after) but the drone went crazy on a side, tried to save but roll and pitch could not do a lot, it kept in the same direction and it crashed into a high wall, falled down from a fourth floor height and “landed” on concrete. Thanks a lot for your help.

GPS fine at first but then goes crazy log included
@Gdpalumbo wrote:
Hello,
I am having a weird sudden issue with my pixhawk. It is very unstable and therefor not trustworthy in loiter mode. The quad will hover and fly fine in stabilize but when I switch to gps its all over the place, so bad I have to switch to stabilize again. I just did one flight where it was bad off the bat, and then one where it was fine for a few minutes but then started acting crazy again. I did the auto analysis of the log but it didn’t pick up anything. I have included the log file maybe someone could please take a look that can read these better than I can? I will try to brush up on how to better interperet the logs but I could really use some help now. Actually it says the file is too big, heres the google drive link to download it. Thank you in advance much appreciated.

Reverse channel input - set in parameter list has no effect (do not reverse)

As in my Topic described: I reversed in the parameter list the channel input of (e.g. channel 2+3 to reverse)
After restart of the controller (Pixhawk 2.1 Cube), it has no effect. The channel is not reversed!
Any idea what I am doing wrong?

Plane crazy pitching in any auto mode - Video
@stuwe wrote:
dear experts,
i’m stuck with this. whenever i switch to an auto mode - preferably to autotune the plane goes either straight up or bottom down and holds that position until stall or crash. no interest in leveling. when i try to hold the plane around the horizon (which i guess is not the idea of autotune) i can do it for a little while like balancing on a ball but once either too much up or down the plane gets “suck” into either direction and the FC is working hard to hold it there. no input effect to get her out!i’ve done many test flights with all sorts of different parameter settings - from low to high, recalibrated multiple times and and and. on the bench it all looks good except when i switch to any auto mode the servos go a bit crazy - then quiet, then crazy again… just weird. i’ve read on crazy servos on the bench and some guys claim that once the plane is airborne this is gone. it seems to be like that for me as well otherwise i could not hold her for a few seconds.
board orientation is yaw 270 which seems to work according to mission planner AH. however - that would be the most logical thing to me being wrong and i 've experienced some strange required settings in that area in iNav and Betaflight - but the AH simulation looks fine.
I’m using a Matek F405-Wing with the latest firmware. before the whole setup with board, plane etc. was flown with iNav without any issues. so i rule hardware problems out. the plane is also nicely balanced and the controls physically limited and adjusted - just the way it shold be - all fine… until flashing ArduPilot…
after more than 10 test flights the plane has never flown in auto mode. it instantly pulls up or down when any auto mode is engaged!
maybe the video helps to explain…
thanks upfront for any advice that could solve the mistery!!!
these are the current settings of the parameters i think are relevant to this issue and that i’ve played around with.
Bank to 25
Pitch Max to 35
Pitch Min to –20
Stick_mixing to 2
TECS_PITCH_MAX to 35
TECS_PITCH_MIN to –35
(All P,I,D set to 1,0,0 wherever possible)
PTCH2SRV_IMAX to 3000
PTCH2SRV_P to 1
PTCH2SRV_RMAX_DN to 0
RLL2SRV_P to 1
RLL2SRV_IMAX to 3000
STEER2SRV_P to 1
STEER2SRV_IMAX to 4500
STEER2SRV_I to 0
STEER2SRV_D to 0.08
Stall_Prevention to 1

My darn motors refuse to rotate
@Skifree wrote:
Hi all. I’m trying to set up a Quadplane, and I can’t get my quad motors to spin up.
When I have the mode set to FBWA I can spin the pusher propeller fine. When I switch to Qstabilize, the quad motors just keep on beeping as if there is no input. I have tested that the motors work by using a servo tester to calibrate the ESC’s. I also notice that if the Pixhawk is disarmed, and the safety switch is flashing, the quad motors beep slowly and not together.
When the safety switch is solid, the motors all beep quickly and in unison.Is there something stupid that I’m missing?
I should note that this is the second quadplane I have done, and I also was able to go to the motor test in optional hardware and check the output. on this one, when I try the motor test, Mission Planner comes back with a “denied by autopilot”.
I’ve followed the instructions on the wiki, Everything else seems to be working well. I feel like this is the last major hurdle to get past.
I’m using Arduplane 3.9.8
Any help is much appreciated! Thanks!

Mateksys F405-STD external compass
@count74 wrote:
Hi,
I am trying to connect an external compass (integrated into a GPS module) to my F405-STD. Without the compass everything works fine, but as soon as it is connected, I get “check BRD_TYPE: Baro: unable to initalize driver”. At first I thought, I had switched SDA/SCL, but the error is persistent, no matter in which order I connect the wires. Is this a known problem? Is there a way to solve it?

Issues with OmniX config
@RezaB wrote:
Hi, I’m back trying to get my omniX rover to work, and am still having issues with getting any motor response. I’ve set up the rover, as the process has been mentioned but get no response.
For example, I tried arming the rover in manual mode, and then moving the yaw stick back and forth. I get no response from the motors, and looking at the logs, it is clear that it receives the rc signal, but sends no servo response.
I was wondering if any one had some solutions to this problem. I am loading both the tlog and the parameters file, in the hope that it may help. omniX.param (14.0 KB)
