Hi,
Is it necessary to have battery power connected when calibrating pixhawk 2.4.8
I thought that with the usb connected it supplied the power source from my computer.
I also thought that having both connected could damage the computer or pixhawk.

Hi, I am receiving STATUSTEXT messages from MAVROS successfully in Ardupilot. I would like to forward those to my GCS. I have configured my “–out IP:port” correctly as I am receiving other information in the GCS such as battery status, HWstatus, meminfo, etc. I would now like to have the STATUSTEXT messages also show up on my GCS. I’ve seen how i can use add the “-f” flag to mavlink command for PX4, is there something similar for ArduPilot?

Dear community,
I’m trying to plan the a series of way points with same spacing along a line so that the rover can stop every 2m to take the measurement, but I couldn’t find any options in Mission Planner that can make it happen.
So is there any way to set waypoints with same spacing along a line and spline ?
Thank you for your help.Mirko

Hi,
I just took my mecanum rover for its first outside drive.
Axles are taken from this:
https://amewi.com/de/drift-climbing-king
Controller is a Mateksys F405-STD with a Mateksys 3-6s (9-27V) PDB. The rover runs on 2s, but the PDB is working without a problem.
A Raspi W zero is used as a companion computer, running mavlink-router and motion, but it is too slow to be useful. I will replace it with a RPi 3B+ soon.

Hello,
I have a Rover (mower) with individual left/right motors operating in skid steer mode.
Everything is working quite well other than I’ve noticed the machine pulls a bit to the left at full throttle.
Is there an easy way to adjust the trim?
The only way I could think of is to reduce the SERVO_MAX for the right throttle.Thanks!

Hello everyone!
I’m having trouble having a mission ran on my skit steer rover because on the flight data screen I keep getting a message saying “flight mode change failed” and EKF flashing in red. I try setting the flight mode to auto on my 3 position switch on my Spektrum DX9 transmitter and get the message mentioned previously along with the rover goes in a circle if I have a waypoint defined as part of the mission. The transmitter can control the rover when it’s on the manual flight mode. Additionally, the flight data screen also prints out “error compass variance” in red. How do I go about fixing all of these red messages and getting the rover to work on auto flight mode?
The specs of my rover:
PPM Encoder from Spektrum AR600 6 Channel receiver to RC on the pixhawk; the PPM encoder’s connections into the receiver go as such: (CH6=>AUX1/CH7=>GEAR/CH4=>RUDD/CH3=>ELEV/CH2=>THRO/CH1=>AILE)
Sabertooth 2x12 ESC set to mixed mode on the dipset switches (1=>ON/2=>3=>OFF/4=>ON/5=>ON/6=>ON)
I’m running ArduRover 3.4.2
Here are my parameters and telemetry logs:

Hey, ya’ll!
I am using Ardurover firmware and I can’t figure out how to make the rover reverse when the Throttle stick is “below” the middle position.
So I would like the Throttle to work so that in the middle position the motor stops. When I forward the Throttle stick the model moves forward and when I reverse the stick position I get a reverse gear.
It seems like a very basic thing for a rover, but I somehow can’t find proper materials for that.
Can someone help?
If I just select “RC1” instead of “Throttle” in “Servo Output” menu in the Misison Planner I get the exact behavior that I want. The downside is in that case the arm / disarm and mode functions do not work, because the Pixhawk is just bypassing the RC signal.
When I am looking at he “Servo Output” screen in Mission Planner I can see that min is 1000, trim is 1500 and max 1900 for Throttle. But actually the stick goes from 1500 to 1900 (and does not allow to go below 1500).

I bought a Traxxas Stampede for the chassis for a Rover using a Spektrum DX-9 transmitter and receiver. For the life of me, I can’t get the Traxxas VL-5 esc calibrated properly. It can be calibrated but needs to be recalibrated each time it is turned on, plus occasionally will go to full speed all on its own. This is unsafe!
I’m at the point of wanting to change out the electronics.
Is there a ground esc that is Spectrum compatible?
This there a transmitter that is compatible with the Traxxas VL-5 esc?
Any other suggestions?Chuck

I can’t find any version of Rover > 3.4.2 with NuttX? All other version of ardupilopt seems so be there for both ChibiOs and NuttX OS? I use Andruv (4G) for telemetry, and I found out it can’t communicate with ChibiOS thru USB, so that’s way I prefer NuttX.

I have a pixhawk 2.4.8 and have set it up for manual as far as I can tell. I have all the parts assembled on a board which includes a pixhawk, gps module, receiver, bec, and servo. I have calibrated so when the board is pointing north it is indicated in mission planner and my campers compass. I can move the roll stick left and right and the servo turns accordingly. I have set the modes on chanel 8 for manual and auto and that works ok. I can set and write way points.
The problem is that when in auto mode the servo moves very very slowly and I have to be a long way either side of the way line for the servo to react. I have read many posts and I can not find how to make the action more sensitive. I have spent weeks on this and hence my need to ask for help.

I have compiled and successfully run my Rover several times about 2 years ago so I am not a complete newbee but close. That was using the old make routines; not waf.
This time I have done the following:
- I have downloaded/cloned latest Rover source from GitHub
- have installed latest Eclipse
- I use Windows only
- I followed all the steps in http://ardupilot.org/dev/docs/building-setup-windows-cygwin.html
very closely- I have done a complete Clean before the compile attempts
- I have run the " configure --board Pixhawk1 " successfully!
- But when I run the rover make, I always get the following:

I built an Arduboat from spare parts I had on my desk and am having some issues. Everything works fine as long as the servo is unplugged. When I plug the servo in, the sik radio loses connection, my FPV camera dims, and the flight controller beeps. I assume the servo is drawing too much power but it is well within spec of the flight controller.
What I’ve done:
- Checked continuity between the servo pins, looks like there is not a short anywhere.
- Servo is receiving 5 volts
- Swapped the servo for a smaller 9 gram (that’s all I had) and it worked for a while. Original servo was buzzing when I plugged it in.
- Unplugged servo, everything else seems to work fine.

When I put In manual mode, only turns one side.I checked Failsafe screen to see if channels are moving ok, and yes, they move.Any Idea why this happens? If I connect directly from receiver to sabertooth works perfectly.
It seems like the cube did not send the info to sabertooth strong enough

Hi all - I’m new here, take it easy on me
I’ve decided to try to use a pixhawk to upgrade my Minn Kota bow mount trolling motor on an 18’ fishing boat as a diy (fun project) solution to their commercial iPilot product. All of the hardware reverse engineering is done and the pixhawk is able to control the steering and thrust on the trolling motor. I’ll try to put up a post documenting how I did it once everything is working properly to help others since it’s been a fun project so far.
As I’ve been working on tuning, I’ve quickly run into one pretty big issue. Since the pixhawk is mounted inside the top pod on the trolling motor, “ground steering” directly controls the heading of the motor, regardless of throttle or vehicle speed. Admittedly I’ve not done much tuning, but I’m having an issue finding any PID or FF settings that will “lock on” to a compass heading in acro mode. What typically happens is that as the back of the boat swings one direction, the motor will stay pointed at the set heading within 1-2 degrees(good), but then when the boat swings the other way, the pixhawk will allow the motor to stray off heading 20-30 degrees before any correction is made (bad). Does anyone have any suggestions on what PID settings might be required in my situation where the heading is directly controlled by the steering motor? I’m not sure that any PID logic is even required for low level steering in this situation. I’m away from the boat right now, but I could send a log file later.

Hi Hi!
I have just started experimenting with ArduPilot on the Copter side of things, for autonomous fleets of UAVs and want to expand autonomous missions to ground assets. Sadly, it will be challenging for me to spend proper time building a rover right now as it is a work related project and other more boring things also occupy my schedule…
And so, does anyone knows of “ready-to-use” UGV with ArduPilot hardware? Or a build/ kit that might/should be straightforwardWithout breaking the bank…
On the copter side, I have bought a few Sky Viper’s and they are great for my purpose, was hoping to find an equivalent on the ground side of things but my frantic Googling hasn’t yielded much…
Cheers and thanks for any input!

Hi folks - I respectfully request help diagnosing this problem from flash log here:
00000006.BIN (748 KB)I’m running Rover v3.5.0 on a one-man pontoon boat with a trolling motor with vectored steering provided via a servo turning the motor shaft. All works fine in manual mode but cannot figure out why no steering action in auto mode. To diagnose this I created the simplest possible waypoint file with a single waypoint about 50 ft to the right of where the boat sits on its trailer in my garage. From the log file you can see the successful thrust and steering in manual mode after the initial auto mode period. In auto mode the prop immediately spins up but the expected steering turn does not happen (despite the “SteerOut” pulse you can see in the logs). I have played with steering tuning per http://ardupilot.org/rover/docs/rover-tuning-steering-rate.html to no avail.
What am I missing here ? On a side note, the thrust (and observed prop speed) are at full throttle in auto mode in this test regardless of the CRUISE_THROTTLE setting.
Thanks for any pointers,
Tom
