Where (what pins) to connect +5volts to ArduIMU from other Arduino cards

I am using an ArduIMUv3, an APM2.5, and an Arduino UNO.

I am able to use one USB (or both)connector to either the APM or the UNO to both load programs and supply power - even if I connect the UNO to the APM via an RC 3-wire servo wire connector.

Print outs

    Is there an ablitity to print out the current Params,PIDs, Configs.

Thx, Brian

ublox lea6 back up battery life

Hi,

this is a question regarding the battery installed on the 3drobotics GPS board:

Recent purchased, the GPS make a fix to the sat's in 10 to 30 seconds.

Now, the board was not used for a while and after hours connected via USB there is still no fix.

I

What is your opinion ...

Regardless of the drone model you have...

What is the most  enervating/unnerving/maddening thing with your drone?

In other words : What would need to change...

I do not want to influence the answers, this is why I do not give more details.

Cheers,

Is Anybody Using APM1 on TradHeli Anymore?

Just wondering if anybody is still using APM1 on TradHeli?

Last night I just did some test hops with the APM2.5 in the new rate control mode.  It seems to be working.  Can't declare victory yet, but it's promising.

But the thing is, a key to it's succe

ArduPlane 2.67 released

I've just released ArduPlane 2.67

This release fixes a number of important bugs, as well as adding a few new features.

This release changes how the level parameters are stored in EEPROM, so it is very important that you re-level your plane after upgrad

QUICK HELP: APM Pitch angle problem

Hi,

In APM (ArduPlane/ ArduCopter) with/ without Mission Planner, we can observe that when the board is titled down, pitch angle changes from 0 (horizontal position), to 90 (vertically pointing downward), and tilting it further brings/decreases it ba

Differences between the hexacopter ready to fly and the hexacopter full assemblage kit?

Hello all,I notice that on the page for the Ready to Fly hexacopter Arducopter, there is an option for $55 sonar. I do not see this sonar anywhere for the full assemblage kit of the same hexacopter-style arducopter.Is this sonar actually included? Is

Altitude not right when auto mode - What I am missing?

Hi,

I have marked my waypoints as 80 meters and some days ago it was working at the exact (79-81) altitude, but last flights I get 55-59 meters even if the waypoints are 80meters. Its a 5 waypoint mission and it doesn't climb... its not the motor, its

APM 2.5 Optical flow enabled weirdness

I have my QAV500 platform tuned very well with 2.8.1, i can let go of sticks and have it maintain position for quite a while without any input.  

However, today I finally got around to enabling the optical flow sensor, following the wiki, ensuring tha

Why is the FBW-B speed target constantly changing.

Sorry to blat this site with more questions but I have some time off and got lots of data from the weekends flying.

In FBW-B I had large speed/power oscillations so started adjusting PIDs in the field. It seemed to improve but think I have just noti

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.

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
