IMU camera control / stabilisation

A simple, example application of the 9DOF MARG sensor array and orientation filter shown in a previous video.
When the angles of the camera pan/tilt/roll unit are controlled to be equal to the angles of the sensor, the camera points in the same direction as the sensor. An example use of this would be to have the sensor fixed to a persons head and the camera look in the same direction as the wearer.
When the sensor is fixed to base of the the pan/tilt/roll unit and the angles of the unit controlled to be equal to the negative of angles measured by the sensor, the camera direction is stabilised to always be level and pointing in the same direction. This may be useful if the camera is to be mounted on a moving platform; e.g. a helicopter.
Hardware used in video: Sparkfun 6DOF IMU Razor (ADXL335, LPR530 and LPY530) with gyroscope RC HP filters removed, Sparkfun HMC5843 breakout board (low ESR cap replacement), 3 R/C servos, x-io Board with .NET library (www.x-io.co.uk).

Nicely done! That's pretty good execution.

[@eelcogg]

You sir, are a hero! Thank you for sharing your work.

[@44avalanche]

Very good job. Congrats!

[@obooth]

Wow, I'm keen on something similar for my Arducopter aerial photography project. Could almost be used in conjunction with target acquisition for tracking a subject. Great video man, exciting.

[@TerjeNesthus]

Super awesome man! Good work

[@Allonsalaplage]

Amazing work, congratulation. I was just wondering how you connected your servos together. Did you just screw right into the servo or glue some parts?

[@canadese]

Great job :)

[@AlvinYapVFX]

Very nice!!!

[@ufo.architect]

That's so cool Id like to add 32 of those to my spaceship

[@cheaptechofficialstore6701]

awesome project bro..😆😅😎

[@wolfxu249]

Amazing!!!! i just wonder what kind of motors are used

[@Ayo04Soul]

@SebMadgwickResearch, l am also grateful for your work. I am currently do a similar project using stepper motors, wifi remote control with video feedback. I would much appreciate it if I can get the materials and more importantly the code used to manipulate the servo's. Also, as the IMU is constantly feeding data to the controller, how and when are instructions set to the servo motors. Are all three motors used to keep the camera horizontal ? I'm hoping to point or track an object remotely yet keeping the image horizontal, I believe it means the camera will not track the IMU, but use the data to stabilize the camera. I would appreciate any feedback. regards, Soul.

[@lion9472]

Man this is incredible! Gratz! Is there anyway to decrease reaction time?

[@saa442]

good work

[@farazsid4270]

Can you do it for RC tank gun stabilization using I MU 6050 and Arduino Nano?? Great video by the way!!

[@yngwievanhendrix]

This is amazing. I did something similar using 3d camera. One question for you. Using AHRS can i also estimate the position in 3D ???

[@grace9465]

Bravo :')

[@nelgrump]

nice!!!

[@rodstartube]

looks like just what I'm looking for.

[@Nomoreidsleft]

Nice, but you need faster servos. You can see the servo lag. The question I have, does it help in eliminating camera vibrations?

[@stardobas]

Perfect

[@RWIZA]

I am going to do the same thing using the wiimotion plus,it will rock I swear

[@vincentjanse]

that is cool

[@abilfida4269]

@SebMadgwickResearch. I'm very grateful for your work because it inspires me a lots. I’ve read your research paper about quaternion and also your included code in C language. I actually have something to ask about how the program goes. How long does it take for one ideal process / loop? (Don’t bother the sensor output rate because I can adjust later). The one loop I mean is start from getting all raw sensor data, then calculating them using AHRS algorithm to get quaternion, then finally getting euler degrees. Thank you so much.

[@MegaRedneg]

Super

[@reis1745]

How did you attach the servos together and the servo to the camera? Some sort of glue or screws?

[@LINKIN31941]

seria mejor con una control de la Wii, solo ocupas dos puertos analógico. pero esta bien tu trabajo excelente

[@detectiveinspekta]

Wow I see this thing going far. Imagine a war room shaped like a ball. Have someone in the middle with a rotating projector.Could use a small helmet for the imu unit. The next step would be to capture motion of someones head.

[@defcon1455]

Awesome! Congrats for your job!! can you give me the code? Thanks!!

[@jeremymartello8024]

hello can you give me the program for this please i want to use it with remote control can you teach me how to do it ?

[@dhiahassen9414]

it is being like "Hey i am watching you" ... but actually you are the one watching it on youtube

[@canadese]

@benybeeJz :D I got the system but not the servos :D

[@gmassano]

is it possible to do this with a wireless control??

[@LineKernel]

hey yngwieanhendrix , what did you found ? i have the same interest

[@revoracer523]

how can i do this with it reading just 1 axis. what would i need? i have the arduino nano already but i dont know what to use for a gyro and accelerometer. its going to control camera tilt in 1 direction (left to right) on a motorcycle. any ideas.?

[@FUTUREPREDICTED]

Johnathan Oey exactly why I'm here ;)

[@canonphoto]

So when and where can I get something comparable to this?

[@canonphoto]

Went to listed website but do not see this product listed. Is it for sale?

[@JohnHansknecht]

No matter how many inputs to the system you have, your output is only 5DOF. I looks very good though!

[@tyrantus6]

@SebMadgwickResearch hello, i saw your 4years old coment under this video, you said there that you can send the source code , and some documentation , can You send me this info or some tips how to use accelerometers?

[@leezhieng]

Any way to reduce the latency of the motion?

[@henhen7890]

You could probably use a faster servo, or include a power supply for it, not sure if there is one in the video. Maybe its the microcontroller or the sensor.

[@misterpotato2]

wow. i also on work for almost same 3- axis stabilization...but i end up sitting in front of a wall. could you help me by sending the papers for your great project.tq.

[@DanMiladinovich]

Oh great! yeah i understand those but do you have any firmware / source code you would be willing to share? Thanks again

[@Videoxon]

very good for my videos ........

[@sorova]

Good but that is open loop! You need to put the sensor on the camera

[@josebuezas]

you should use faster servos, and then it would really work A digital high speed servo...

[@leftysomething]

PLEASE PLASE PLEASE can i have the code?

[@deadking13]

Wall-E !

[@waleedalhamdi319]

nice work , may i know the coding you are usung ? @SebmadgwickResearch

[@user-di2tg1ll2v]

ускорить реакцию камеры и можно смело продавать

[@MaxLeRoi2]

ну для цього треба просто взяти серви швидше. Чи окреме питання подати, ЯТД.

[@tecnoshack]

good work
