What IMU is better for the quadcopter?

I am trying to make a quadcopter; but I am stuck in deciding which IMU should I get and like what features should I look out for? and do I need to programme it in any way??

How to measure Velocity/Acceleration of bicycle

I want to measure velocity or acceleration of a moving body(E.g: Car,bicycle,etc) without using a GPS module. Is it possible to calculate coordinate acceleration or velocity using an IMU.

How to control the height of Quadcopter?

Hi, Is there a way to control the height of the quadcopter using the MPU 6050. I know that the sensors i.e. accelerometers and gyroscope measure the orientation of the copter and stabilizes them but how would u measure or like control the height of the copter? Is the controlling of height depends on the IMU unit of completely on the throtle provided to the motors?

Can I control the height of quadcopter using MPU 6050?

Is there a way that I can control the height of the quadcopeter using the MPU 6050? I know that the accelerometer and the gyroscope are used to measure the angular acceleration and the orientations respectively and stabilise the flight. But how would you measure the height of the quadcopter?

Skeleton Tracking Using IMU Sensors?

Hello, I found here on https://www.instructables.com/ a lot of topics talking about gyroscope, accelrometer, & magnetometer sensors. How they work, the idea behind them, and how to make use of the data returned by different sensors. Then stays the ultimate problem of filtering the data and getting reliable data. Then there's an online algorithm for that written by PhD student which is a very good algorithm. It'll be used on PC side as I understood from some gurus that such algorithms will get the arduino to its knees. There're some sensors out there that you may cost you a little more but they have the option to get filtered data directly from the sensors. Then comes the question itself. Is it possible? Well that was my bachelor project to read how other people did it and redo it. Then I remember the first time I was searching for how to work with these sensors .. it was a mess. Then I made a decision to make this thing available for everyone to play with. So far I implemented "Arm Tracking" and based on the idea .. anything else will be possible actually. I wanted someone (or some people) to help or brainstorm with me how can we make it easier for anyone who wants to start with the sensors .. from writing arduino library to simplify this .. to the "Skeleton Tracking" thingy. Even if it'll only be explanation but I wanted it to be one big guide for everyone just to pay back those who helped me with other stuff they were good at. Even if the guide is about gathering resources in one big topic and linking them together. I hope I could deliver what I wanted to say properly  :D Thanks in advance

3D Precise position/orientation tracking for body-worn camera

Hi all, It's not a new question but the available technology keeps changing so I'll ask this again, having not found any current answers online that are useable at a diy, non electrical engineering level... I'm working on a project in which a body worn camera is tracked in space, then recreated as a virtual camera in the corresponding virtual 3d space (kind of like a lo-fi version of the cameras used on the "Avatar" set). This is to be done over 15-60 minute durations in an indoors area of about 30X30 feet. What I need for this is tracking of the camera's position and orientation in space, precise and continuous (as much as I can get, but at least within and inch or 2, and a few degrees, of the true values),  to be either logged on the tracking device and/or transmitted to a computer on set. Since it is body worn, it needs to be light and wireless. Since it's on a moving body in a space with some objects in it, optical tracking isn't really a good option. I looked at a wide range of solutions, from "flock of birds" and the inertiaCube on the crazy-expensive side to sparkfun's IMU sensors, but frankly am a bit bewildered by the selection and don't know how to figure out which is the best to try first, given my needs. I'm really not looking to reinvent the wheel or rebuild everything from scratch, just find a solution for this not costing more than a few hundred dollars that is fairly reliable. Software-wise I want to be able to get 3D XYZ position and rotation values from it that I'll be able to use in Realtime 3D software such as Max/MSP Jitter and the like. Any ideas, stories of previous experience with such setups, links, etc would be extremely welcome. Many thanks! nadav

double multicopter flight controller? Answered

I wanted to know if there are any flight controllers that have separate sensors. I want to use 2 either quad, hex or octo flight controllers with one setup as + and one setup as X to make an octocopter, duodecacopter or hexadecacopter ( 8, 12 and 16 blades respectively ). I want to have a a 6 or 9 DOF IMU connected to 2 separate controllers for larger multicopters. Either that or would anyone know how one might go about designing an arduino controller using either a pwm shield or a TLC5940. Thanks in advance

I bought an ArduPilotMega 2.0 - want to build a quadrotor - now what?

So, I'd like to build a quadrotor.  I looked at plans out there and it seemed that an ArduPilotMega 2.0 controller was cheaper than the old ArduPilotMega + IMU board, and more advanced.  So I bought it.  But I don't understand a lot of the terminology the RC / UAV crowd throws around, all I know is it's basically an Arduino - which I have used - with special logic for flight stuff like gyros and multiplexing.  Besides that, I don't know where to start.  I know I need to get some lightweight brushless DC motors, radios and a radio controller unit.   but what type, etc.. ?   Where do I start?
