Erratic gimbal roll servo - overrides mavlink command

Hello all,

I am having an issue setting up a servo gimbal in ArduCopter 4.0.3. I am using a companion computer to send pitch and roll commands to the gimbal ( vehicle.gimbal.rotate() ) while the vehicle is in guided mode. The gimbal pitches down through 80 degrees of movement just fine, but when it gets to where the camera is pointed straight down towards the ground, the roll servo (not the pitch servo) starts twitching and runs to one of its limits, so that the camera is still pitched downwards but is now pointed off at an angle. As I rotate the drone back and forth about its roll axis the roll servo responds.

This makes me think that the autopilot is overriding my mavlink command to pitch the gimbal down without any roll or tilt (vehicle.gimbal.rotate(90,0,0)). I have made sure that MNT_STAB_ROLL, MNT_STAB_TILT and MNT_STAB_PAN are all set to 0. Attached is a screenshot of my camera setup with servo PWM settings.

Any advice is appreciated

Thanks

!

Motors arming after turning off remote controller

Hi guys,

I’m running into a problem that I didn’t notice before.

When I turn off the radio controller but the drone stays on, the motors suddenly start spinning. What could be causing this behavior? Do you think this is something that could be adjusted in the parameters?

Dual Power Modules?

I have 2 mauch 200A units that I would like to install into my airplane - one for each wing. The units require a BEC to power them. Can I run separate BEC’s for each unit and then plug them into power1 and power2 respectively? Is there some switching going on with the power input to the pixhawk that would safely allow me to plug in 2 BEC’s? Or is it safer to power the current sensors from one common BEC?

Yaw not changing during LOITER_TURNS waypoint

I’m having an issue where my quad doesn’t rotate in the yaw axis when performing a Loiter (turns) waypoint. It will go to the waypoint and hover in place (radius=0) or move in a circle without yawing. In QGroundControl I can see a blue target direction indicator circling around the compass, but the quad’s heading does not change.

When following regular waypoints the quad does yaw toward the next waypoint.

I’m using the default CIRCLE_RATE = 20deg/s.

Adjusting the cruise speed

@sandre wrote:

Hi,

I want to adjust cruise speed.

At default settings I have a ground speed of about 42km/h (without airspeed sensor), and I think the optimal speed should be lower. In the mission planner I have value “Cruise speed”, default 12m/s. I updated it to 9.5, and also lowered minimum FBWA speed, but don’t see any change in actual cruise speed.

How to set cruise speed?

Are these different settings with RTL speed? For RTL I prefer keep it as is - less efficient, but more reliable.

Is it possible to adjust cruise speed during flight, providing value from transmitter channel, like in iNav?

Regards, Andrey

OpenTX Waypoints

Hello all,

I use a pixhawk in my baitboat.
Now i use a android tablet/phone with the Mission Maker app.
Here i saved several waypoints wich i send to the boat and put the boat in auto mode.
So every time i want to drop my bait i need to use the FlySky transmitter and a android device.

Now i found the Jumper T16 / Radiomaster with the OpenTX Yaapu plugin.
This looks really good, but i would like to know if it is possible to send waypoint from the transmitter with OpenTX to the pixhawk without using a Ground Control Center software.

That would be really amazing so that i only have to use the transmitter every time i need to drop the bait.

Regards,

Wouter

Good morning everyone, I bought an F4 V-6 and when I pass the image through it, the image comes out with a lot of letters “VVVVV” in Oculos, I already exchanged the camera for another model, but the letters “V” appears after going through the dish.

Can someone help me?

Behind the plate, the solder bridge was made between the VCC and the RAM
I’ve done the test without solder and with the solder and the problem continues

Hi. Im in hurry, i have limited days to finish my task.
I use pixhawk, emax rs2306 2750kv motors, ublox neo m8n gps, 50a hobbywing esc. The problem is that, when i try to launch my drone, the front side of it launches faster and it goes to flip and crash.
What should i do, what is the problem?

MP DATA tab layout for different models

Hello,
I have four craft running arduplane/copter and use MP as the ground station, only one at a time !
The SYSID_THISMAV value is recognised when connectiong to a model with the expected value appearing.

I’m expecting the DATA tab to resort to the layout I chose for that model (eg. one model has two GPS values etc.) but it brings up the last layout used.
Am I expecting too much? or am I missing something silly ?

Thanks

Pixhawk 4 mini inappropriate?

@kitchen_faucet wrote:

Hi,

For starters, I’m new to this pixhawk/ardupilot stuff.

About half a year ago I ordered a pixhawk 4 mini w/gps, from holybro. Mostly because of the physical size and still having all connections that I thought I needed. I also thought it was relatively modern.

Now when trying to set it up I started to study this ardupilot/arducopter stuff a little closer. Then I read that everyone here seems to recommend another unit, pixhack v3x (iirc?). After searching a bit I can’t see anyone saying they are using the px4 mini on a heli.

I had no idea there could be other differences than just the IMU version and external connections. It’s not very clear to a newcomer.

So, is the pixhawk 4 mini unsuitable? What is the difference compared to the recommended units?

Did I make a big mistake? will this project fail miserably or could I make it work?

Altitude increased after switching from GUIDED mode to STABILIZE mode

Hi,
I flew the drone indoor today. I used MavProxy to forward the serial port to two ports. One for using visional positional estimation to reduce drift. The other one for drone velocity control. The scripts ran as expected. However, when the drone goes near the net. I changed to Stabilized mode and the drone altitude increased a lot and hit the net.
Is there some method to prevent this altitude increase caused by mode changing?

Feature Request: Message colors and notification

Hi all,

I work at a company called Iris Automation which makes a detect-and-avoid solution for drones flying beyond visual line of sight. Naturally, this comes with its share of regulations for the vehicle, the DAA solution, and the ground station.

I’m writing to ask if Mission Planner can be enhanced to meet some of these regulations. Specifically:

  1. When displaying Mavlink STATUSTEXT messages in the “Messages” tab, the messages should be highlighted with colors indicating their severity. AC 25.1322-1 defines the following guidelines:
  1. Color Standardization. The objective of color standardization is to maintain the effectiveness of visual alerts by enabling the flightcrew to readily distinguish between alert categories.
    a. Visual alert indications must conform to the following color convention (§ 25.1322(e))
    (1) Red for warning-alert indications
    (2) Amber or yellow for caution-alert indications
    (3) Any color except red or green for advisory alert indications.
  1. If the “Messages” tab is not visible and a message comes in with severity WARNING or greater, then show a visual indicator that an urgent message requires attention. This could be displayed on the HUD or elsewhere.

I’m willing to help out and contribute code to achieve this. I’ll be forking the Mission Planner project to see what I can do. Does anyone have tips on where to start? Is this something that the Mission Planner developers are willing to include in the official version?

Thanks in advance for your help! Have a great day!

Guided mode min velocity?

@Wazootyman wrote:

I am flying a drone using guided mode and setpoint raw commands. The commands include both lat/lon and XYZ velocity (neither input is ignored). When I command a higher velocity (3-5 m/s), the velocity works. But when I command a lower velocity (<1 m/s) the velocity does not change. There is no perceptible difference between a command that sends 1 m/s, 0.5 m/s and even 0.1 m/s. The drone should be crawling but I would guess it is moving over 1 m/s.

Am I doing something wrong?
Thank you for your help.

Position controller not updating?

Hello all,

I’m experiencing some weird behaviour during waypoint missions.
Every now and then the heli will drastically slow down half-way between two waypoints, then speed up again. There’s no mission item there, no reason for the action.

In the image below I’ve plotted waypoint latitude in yellow, target position and actual position. It happens all over the place but the most obvious point is at 4.25s. This was in the middle of a 300m straightaway, the UAV pitched back violently to brake for no apparent reason, then continued You can see that the target position seems to stop updating or something?

Any ideas?

Arducopter have lot of baro drift over long time flying about 10 to 15m (+ or -) altitude value .
Prevent this is there is any method available using downfacing lidar when copter come within lidar range it should take lidar value instead of barometer value by default.
