Self-guided Glider

I am currently designing a glider (no motors) for long duration flights and I would like to make the glider at 4 pounds (1816g) or less. I am considering a carbon fiber frame ( I don't plan to do crazy stunts with the glider ), and also considering t

IMU 3000

Just a heads up, Invensense IMU3000 chip is now available for purchase. It's a 3-axis gyro that's designed to be paired with a digital 3-axis accelerometer, and does sensor fusion on chip, removing the need for kalman filtering on an external MCU. Ou

Ardupilot with vicon system

Hi Anyone knows how to integrate MATLAB with arduino/Ardupilot via serial communication and how to integrate the VICON sensor system with Ardupilot?

Ardupilot and arducopter

Are the ardupilot and Arducopter the same boards? can they use the same IMU and main boards?
Is the only difference between the two is the code?
Or are they different in the hardware (I saw there were some versions of the ardupilot and it seems that th

Shipping DIY Products

Hey,

I have ordered the xyz sensors and the ardu shield kit from diy drones. the stuff is with a relative of mine in USA. I wish to know weather or not the US Customs will object on sending the stuff to me in Pakistan as my relative will courier the s

ArduPilot Shield Pitot Tube

I'm building my UAV airframe this weekend and I need to install the active pitot tube in the wing but my ArduPilot Shield kit hasn't arrived yet. It appears that the active tube is just a plain tube connected to the Shield by fuel tubing. Can someone

LED LIghts and GPS Lock

another newbie question.

i am getting the following lights on the boards;

IMU

solid orange, occasionally drop out then back solid
Solid blue, again occasionaly drop out then back solid, GPS lock after a couple of mins
no red but when i move the IMU aroun

IMU shield/ oilpan gyro problem

I am using configurator v1.2.1 and software 1.31 for my arducopter.
The gyros do not show any movement when I twist and turn the quad.
The acell pitch and roll move all over but the gyros stay centered and do not move.
I ran APM_ADC test using the seria

Frequency for PID computation

Hello,

what must be my PID regulation frequency for my QuadRotor?

1ms, 10ms, 100ms?

It seems ESC for Brushless motors can't change values under 20ms, so it is not necessary to compute PID quickly?

I have an IMU (Razor 9DoF) and i communicate with it

HobbyKing?

Hi,

Has anyone had an bad experiences with HobbyKing?  I went through the motions of purchasing a RC txn and rxn from them and realised I had the wrong item in my order.  I contacted them to cancel immediatly after reecieving the confirmation and was

Interfacing question~

First of all, I am back! as I said that I went for my examination.

Now it's time to continue with my project.
A question had come to my mind recently.
Because I am going to do a ground station which includes the basic 6 air gauges, what is the hardware

ArduIMU+ V2 and LS20031 GPS

Hello!

Not got a 3 way switch?

I have a Futaba 6EX which has two 2-position switches on channel 5 and 6. I am unable to mix them to form a 4 position switch according the Futaba (marketing or honesty?) so how do I create more positions on my switches?

Why not use an Arduino Pro Min

How many R/C channels needed/recommended for an Arducopter?

Arducopter vs Aeroquad

Can someone tell me what is the difference between these quads?
Do they use the same boards?

IMU Gyro Stability

Greetings everyone. I'm working on a project where a computer steers a farm tractor via GPS. Getting accurate position data is easy. My challenge has been getting accurate heading data. I have tried a MEMS gyro on the yaw axis, but it shows a lot of

getting problem with the arduimu v2 flat ver1.7 code

hi all friends,
i have started to build my quad rotor with arduimu v2 flat,i was looking thruogh the code,initially i am using arduimu v2 flat as a main circuit board and future scope for magnetometer and gps module,and accordingly i set the parameter

Ardupilot for a car

I am interested in using ardupilot in a rc car and believe in needGpsArdupilot itselfBut I have read the user manual and it does not mention how to do it for a car.Also, is there a way for it to respond to the ground beneath it or control it's speed

New way to TX/RX

Ok guys, I am COMPLETELY new at this, so please forgive me and feel free to shoot holes in this.

I am wanting to build a drone that is pretty hefty and could drag up a forward looking video, full autopilot, downward looking video, and downward looking
