Hey
TOPIC: In recent years, flying robots such as autonomous quadrocopters have gained increased interest in robotics and computer vision research. For navigating safely, these robots need the ability to localize themselves autonomously using their onboard sensors. Potential applications of such systems include the automatic 3D reconstruction of buildings, inspection and simple maintenance tasks, surveillance of public places as well as in search and rescue systems.
I need some assistance in building my autonomous Quad-copter
I am aiming to use arduino mega ship and a camera and for sure all components of quad-copter such as motors and gyro and accelerometer and ultrasonic.
and want it to be in a follow me mode(optional).
If someone is able to help me in coding and other procedures,i will be so appreciated.
Hi,
What is your electronics, programming, arduino, hardware experience?
Tom... 
Glad to help but you are in begging stage that means you don't understand yet what you actually need,
you gonna need way more components than what you want to use and way expensive quad components.
Yes it's possible to do but the price is going higher every time you add a extra task, extra task = more time,
more money, more testing. The price of this project can be low as well but you need to understand that
what you actually ask from others to help you it's not just free time hobby but work.
Building the quadcopter is the easy step, adding sensors it's not hard but making it to interact with the arround
enviroment it's way more work than you expect and you ask a extra task to follow you.
I will agree with Tom
Tell us what you know/experience so we could know what to give you back.

i worked several time on arduino board and for different projects such as line follower and autonomous sumo robot. i know about sensors and measurements data. As Dom said, building the quad-copter is an easy task and he is right. my aim here is to make my quadcopter follow me while skying. Some said that the arduino board won't handle the data image processing from the camera because it is very low in processing unit. this is my concern. Will the arduino mega able to handle image processing and 3D recognition(computer vision) or i need to search for another hardware ship?
thanks all for Your assistance
About the following part you can make it with a GPS tracker, meaning that you gonna use a GPS on your quadcopter and a 2nd GPS device on you, the quad will receive the real time data and will virtually follow you.
About the camera image processing and recognition you need way more than just a chip, I would recommend to
start with a android (OS) you need processing and graphical processing units.
Your project sounds fun because I'm doing a similar flying project right now and I would suggest you to
start with the 1st part, gps tracking/following. About the cam you need way more components and bigger
quadcopter.

I would suggest you learn to fly a cheap one before you go for the more advanced design.
Could save you money in the long run.
I have seen a novice with a £1000 quad who splunged it 30 seconds out of the box.

Image processing such as you describe requires a lot of power and memory.
I think it unlikely you will find something light enough for an aerial device.
Cameras and recorders such as the go pro work but will not do dsp.
i will first work on the GPS mode and will use the arduino and see if it will work.
After i am done in this part i will work on the image processing which is more important. some said u need to learn about gimbal axis and a lot of linear and mathematics equations to make the image processing accurate and help u to use follow me Mode
Dom Keep feedback me about your process in the GPS and tracking. willing to cooperate so we can achieve our common goal.
Thanks all for the cooperation and i really appreciate

The Occasion i mentioned used a quadrocopter with GPS guidance and return to field capability.
He made a mistake with waypoints which took him over water.
Despite being about a metre away from him and transmitter I was unable to rescue.
The onboard gyros toppled i think.
They crash quickly.
I would suggest you learn to fly a quad first before experimenting
i know very well how to fly it, Won a race competition with my quadcopter.
But now we have a new competition by flying the quadcopter through waypoints without our intervention.
Hope i win this one.
If u have some infos about what u used as equipment, can u please fill in so i can compare and see to tweak my outcome as most as possible (including coding if possible).
Thanks again

I am unfamiliar with that , do you have links please ?
If you need to dsp processing of video i would suggest you need something seperate from your flight control system
here is the project.
Like i said before my first aim is to fly this quadcopter via gps and compass.
camera and image processing is a different story.
so first i want to make sure my quad is flying autonomously.
Check the attachment,the proposal circuit may not be accurate or beneficial
Thanks again for your cooperation
Competition.doc (203 KB)
Your attachment appears to be missing.
oh i fixed!!!
double check and feedback me
Thanks again

Holy ****
Are you sure that link did not come from the CIA to trap the bright ones ??
Hahahha!!
It is not that hard, u may find it strange but step by step u will find it easy.
Like i said before, will start working on GPS and compass mode so it will fly through way points and then i will work on the vision and data and image transmission so it can detect the landing zone.
So if u or someone else worked before on the GPS and compass mode for a quadcopter please feedback me about the process u worked on it and if it worked or not.
same issue for the image(i think arduino in this case won't work since u gonna need a better processing unit)
Thanks again

1000 can buy you a quadrocopter which will follow waypoints and return to home.
Image processing is something completely different.
Its nothing to do with quads although it may be able to control them.
I suspect that you need o look at Digital Signal Processing or CGI separately.
Its a very non trivial appliation
This stuff is used for terminal guidance in cruise missiles hence my earlier toungue in cheek comment.
You gonna build this quadcopter from 0%?
If you gonna build your own quadcopter from 0 will be easier to understand what exactly do you need,
for the autopilot you need a gps, compas and quadcopter control code.
I will post the rest other time i'm busy need to go

Hi,
I like your enthusiasm.
The programming involved in keeping a vehicle level and stable in the air by controlling each of 4 motors, with cross breezes etc, will not be an easy task.
But as Dom has said its a good way to learn about these things.
