IDEA Required: For a Master Thesis Project.

Hi All,

I was brainstorming on coming up with an idea based on UAV, Quadcopter application in real-time. In the area of surveillance there are many different ideas that can be employed.

Battery Life

For instance, tackling the area of improving battery l

2 Aileron channels. Has anyone got differential working properly?

I have put the 2^nd aileron on a separate channel so that I can have differential (defiantly makes my plane fly better). It was working fine with the APM not connected. I have set it up with the wiki brief.

What happens with mine is, all though both a

I tested the 3DR GPS uBlox LEA-6 for high altitude however I discovered something strange.

In the datasheet of the uBlox LEA-6 it’s written that the altitude limitation is at 50'000m so you could use it for ballooning. However I tested it with an AP

GYRO DRIFT Compensation: "How To" in APM?

Hi All,

I use APM, and I need to do 'drift compensation'.  I have the following:

ahrs.pitch, ahrs.roll, ahrs.yaw.

drift vector =( x, y, z )

I use an external Compass for Yaw , and it is enabled. Now, how do I make use of the vectors above; do I need to a

Arduino Due Multi-Copter I/O Shield

Hi all,

  I have begun a new project that relates to multi-copters.  I have designed a shield for the arduino Due that makes using one for a multi-copter project a bit more convenient (or really almost any robotic type of project).  The PCB is current

Quadcopter Applications: Thesis project

Hi Guys,

I was interested in doing my master thesis research in the area of UAV. I wanted to know the topics of reseach in the area of building surveillance using a quadcopter.

I was looking for specific areas of improvement and/or implementation that

How to fix incorrect pitch, yaw and roll values

I'm currently connecting my APM2.5 to my pc using a usb. When i connect it to the pc using the mission planner the Roll Pitch and Yaw are always waay off from the actual orientation of the board.

I have discovered the values for roll pitch and yaw see

Fly away - saved at 1.8km - help with logs please

I had a pretty exciting flight on the weekend. My plane with APM2.5 flew most of a circuit in Auto mode correctly, but towards the end it just flew off to sea!

I wanted to monitor the strength of the telemetry link by flying ever increasing loops. Eac

Intermittent USB connection

Hi all

We recently purchased the ArduCopter kit “3DR ArduCopter Hexa-B Frame + Motors + Full Flight Electronics Kit” and have had some trouble configuring the APM.

We have done the following:

• Built the and soldered all the parts including power board a

Quadcopter Control-Function Layers

Introduction

Quadcopters is a very active topic, it is fun and easy to build, and make use of rich set of sensors for stabilizing and navigation. So if you like flying, mechanics and programming then go for quadcopter.

We can find on the Internet a lot

Having a Little Trouble Playing AVI Files Recorded from MP

I recorded a few avi files of the HUD with a video feed from within Mission Planner, but they won't play back for me.  I have downloaded a few codec packs, but no go so far.  I'm running Windows 7, 64 bit.  Any idea of what I need to do to get these

How to Maintain In Flight Speed?

Hi there, quick question.  I'm flying my hexa on the latest arducopter code and an APM 2.5.  The default PIDs work fine for most everything, it can even navigate waypoints with ease.  However, I have the auto mode speed set to 5 m/s, yet I see the co

Waypoint list corrupted after failed write? Plane flying through mountain.

Hi,

Yesterday my APM2-equipped glider scored its 3rd tree landing, and the 2nd related to software issues if I am not wrong. A flight plan seems to have gotten corrupted.

I had my new GPRS data connection in it. The APM software had my modifications fo

Com Port doesn't existed error - Problem solved

Unable to establish a connection.

The port 'COM16" does not exist.

Being kinda new to this I was using a MP with the 9.0 Mavlink with the 2 APM 2.0 & 2.5 boards I have. But I wasn't getting any HUD on the MP. Using the Mavlink 9.0 I could upload Firmwa

Paralinx Arrow HD Video TX/RX

I came across this video transmitter which claims to have 300' (90m) range LOS and latency <2ms.  

The TX which is like a dongle weighs at 2oz (56g). As i don't have expirience with HDMI devices i assume the TX is powered from the camera if HDMI slot

Did my APM die mid flight?

I think my APM just died midflight of course leading to a crash.

I have attached the tlog. The flight does not start till 80% through the log.

I took off in manual switched to loiter then to auto for a 3 waypoint mission.

The plane flew the mission then

Question concerning logs + bad motor

I managed to flash some turnigy plush ESC's for my APM quadcopter and at firts glance it flie great. You can really see and feel the difference compared to the stock FW of the ESC's.At a certain moment the quad just flew to the side and crashed but l

Flightmode stabilize is not working wehn switching from manual to stabilize

Hello, I just tested my very first Arduplane and found a strange behaviour when switching from manual to stabilize. When I switch from manual to stabilize and then move the plane, it does not do anything. It seems that it stays in manual mode, but in

Encryption in 3DR radios?

Hi,

is there any encryption and/or authentication on the air interface of the 3RD radios? As I understand, XBees run AES-128 on the airlink.
