Arduino + Nunchuck + Pan and Tilt Camera

[drozdov79]

Hello! Do you used original Nunchuck or clone?

[2nigelstone]

This is a fantactic tool, can you agree that people with a handicap wich cannot move their hands or arms with t his tool they can control a robot arm.

I got an neck injury in 2005 and try to find a tool to help me keeping things in my right hand so i am sure that your solution makes this possible with your arduino project.

Lets make a deal together and find a solution for millions of paralised people.

Greetins Nigel from Belgium

[somud1]

this code that you released works only for the decmila board.

i want to make this work on the arduino mega but i realized that the sda and slc pins would be different how ac i change the code so it works on the mega.

also, i am using a third party nunchuk and the way these works is different how should i go about rewriting code? do you have a copy of the code with commenting?

[Frajedista]

Not bad! There's no noise at all! Perfect! Awesome work!

BTW, I've been working with arduino and the nunchuck too ;) See it in my channel :D

[masterproducts0]

I have a nice idea! put this camera on a robot.

[gomiz3]

brilliant!



[kle8309]

reminds me of a chicken

[akadsgold]

thats looks like a little chicken

[widdalightsout]

can i do it with continuous or full rotation servo ?

[andreahaku]

@widdalightsout Yes I think so but I never tried.

[marselsipod]

Nice! I think ill order an arduino now, lol

[andreahaku]

@marselsipod Arduino is the best phisical computing platform ever. Go buy one and experiment! You'll have lot of fun like I had... and learn a lot of things, like I did ;)

[prestondocks]

Thanks for the code. I had struggled with this for a while and could not get any sensible movement, but your code is spot on. Thanks again.

[andreahaku]

@prestondocks The code is probably "old" and needs to be revised. I'm not in that thing anymore so don't have time to work on it, but I'd be happy to publish an updated version of it, if someone wants to do it.

[Frankjikes]

@andreahaku can i have an updated version of the code as i want to reproduce something similar.

[ZOOKAROOS]

you should put it on a crane and make a video from the top

[andreahaku]

@ZOOKAROOS that was almost the reason why I developed it :)

[ich3210]

Can i do that with my iphone too?

[andreahaku]

@ich3210 I think so, but I don't know if there's an easy way to interface with the iPhone. Maybe someone has developed some app for that.. don't know sincerely.

[scratchedguitar]

That is the best thing EVER :P would be awesome to see it with a video feed from the camera side by side :P

[andreahaku]

@scratchedguitar you're right... I did it as an experiment but then I stopped "recording" my developments.

[2nigelstone]

Fantastic apllication, do you realise what sollution you build for people with a fycical handicap which cannot move there hands.With this project people can move with their head and move a robot arm to pick up objects.

I love this application Compliments Nigel

[andreahaku]

@2nigelstone Thanks Nigel. I'm happy if that can be really helpful for someone. Keep me updated if someone really find some interesting use for that ;)

[KrassesZeug]

Wow!

[EmuAddict]

..so It's better than anything you could make.

[Pvsmuntje]

Nice! How did you make the pan&tilt mechanism? Did you just glue the servo's together?

[andreahaku]

@Pvsmuntje I used Lynxmotion kit but there are many ways to do that. This is one of the easiest and clean solutions.

[gingrrr]

You could attach a device like this to a snowboarding helmet, including a nunchuck, and smooth out the movements of your head. So just filming straight down the hill.

[VALKIR4636]

sigh, it moves so fluent ... mine just jerks arround altho I use smoothing for the output :( can u give me some pointers on how I can reduce these "hiccups" ?

[graymalkin1234]

@VALKIR4636 When processing the data from the nunchuck try using an average from the last three readings, it will add a slight delay but should compensate for such hiccups.

[nx2overide]

wow im pressive.. but creepy as it look alive!!!

[muietumuie]

you suld do a mod here :when you dont press button camera don't move when you press you can move no?but it is realy good great job

[molinobeer]

he actually did it...

[EvilInYourCloset]

Very cool!

Hm, what type of Servos did you use?

[LargoUsagi]

i second that question

[andreahaku]

HS-422

[BootsSiR]

very neat!!

[Iolfish]

love that shit :D its look like a birdie :P

[nemesisdog2]

very sensitive isnt it

[96bikerider96]

i'm making a robot with front, back, left, rifgt, controls, controlled with the nuncuk's analog stick, and a pan&tilt camera holder on top, controlled by the accelarometer :)

oh and it will be wireless :D

long term project though, still have to buy another arduino...

[Magganrchy]

Very nifty I'm working on something to control a robotic arm with a Wii nunchuck...similar idea

[weevil76]

Great job! I've been looking for something like this to use as a basis for some animatronic eye-movement creature fx. Thank you for sharing your work!

[jrichman63]

NOW GET THIS ON A RC PLANE! and then we are talking!

[96bikerider96]

theres one on a helicopter!

[curlyfry562]

This is by far the coolest Arduino project I have seen. Well done.

[rottenman2010]

they should install this in FIGHTER JET for controlling guns ;)

[rockindavid310]

that my friend...is genious!!!

[jimmybobson123]

rules!

[alfcoder]

what is the accelerometer part number?

[iestynlloyd]

Awesome work!

[andreahaku]

Thanks. On my website you can find the code. Maybe it can help you to smooth and speed a little your setup.

But you have to fine tune it to make it work well with your servos.

Let me know if you need any help ;)

Ciao!

[garymusgrave]

would you mind sharing your Arduino coding for this application? Love the idea and would like to play around with it.

[YouMockMe]

that is totally cool... how does the Wii work? is it liquid murcury craeting connections? any information is great I'm just getting into arduino and this looks bad ass. Great work!

[aaronz101]

It uses accelerometers and gyroscopes, I THINK.

[andreahaku]

only one 3-axis accelerometer!

[bbqpring]

that is sweet, i think that could be really popular with a alittle tweaking

[jfarr245]

I noticed that on line 192-198 it appears as if there is a reference to joystick commands.

I would like to be able to push either the "C" or "Z" button and be able to use the joystick instead of the accelerometer (add controls for two more servos/stepper motors).

[jfarr245]

I downloaded your sketch to my board... Thanks for making it available on your website.

[andreahaku]

You're welcome. Feel free to contact me if you need help.

[soshimo]

Wow, excellent work. I've been struggling how to get yaw working with the nunchuck (you must be using a trick since the accelerometers in the nunchuck can't sense yaw - I noticed you were using left/right gestures, very clever). I've got pitch and roll down, perhaps your site will have some information to help. My platform is the propeller, but my POC was on Arduino (just hate that I use 90% of my RAM for a little program - use about 30% for equivalent on prop chip, and it's multicore 32bit)

[andreahaku]

I agree with you but developing with Arduino it's a snap! And now there's a version with double the RAM. But even if Propeller has got much greater potentials I'll probably continue developing in Arduino as actually I don't have time to learn something new :) Thanks!

[soshimo]

Well, one edge the Arduino certainly has over the propeller is freedom of development platforms. You can basically create your own gcc toolchain if you have the skillset, whereas with the prop you are limited to a BASIC-like language that uses python style delimiting or a flavor of assembler that ends up being interpreted as well. Parralax is good for the beginner, but you are right, the true power lies in C.

[jfarr245]

Can you post a website where I can learn more about writing the code to duplicate your pan/tilt setup? That is really impressive. Thanks!

[bilexperten]

I tink it wood be cool to putt the camera into driver position in a small RC car and integrate the Wii kontorll whitt the transmither :D Sorry for ban englesh.

[thekingdeeps]

wicked!

now, just scale up the robot, and you could do anything!

giant diggers!

battle mechs!

etc!

[andreahaku]

... then conquer the world! :D

[twilightprod]

Sweet Very graceful Motion!

[andreahaku]

I'd like to thank you and all the people that made very nice comments on my works. Really thanks! I hope to have time to continue developing in it and go wireless :)

Keep in touch!

[Elswalbe]

now just add legs controlled by the thumbstick and a beak and you'll have a little bluebird robot. That would be pretty sweet, aye?

[dastardlydanish]

where do you buy your servos?

[fernwood]

That took my breath away. Inspiring!

[odavilar]

Im searching some servos, but i dont know what kind of it, what servos did you use? model? or where tu buy them?

[jorge10206]

what type of connection , protocol does the nunchuck has

[alizta]

I think it was essentially an I2C bus, so it should be doable with most micro controllers.

[dustybikeeeeeeeer]

dude that is seriously cool!!!

[LordYggdrasill]

Pretty cool, but I was wishing that closer to the end of the vid you'd be shaking the Wiimote more rapidly so I could see how quickly the robot could react.

[jorge10206]

The Servo arrangement is very simple, but looks great. We will be using it for a project.

[cyrofilho]

Very amazing, nice work!

Hey, where did you find the datasheet and code fo the Wi joystick?

Mail me for share some stuff about ps2 joystick code, at keyboards ...

[alcurb]

Nice!! Reminds me of military head-motion-actuated camera. Mount the nunchuck and a screen on the helmet and you'll have similar system.

[andreahaku]

That example has been made for the development of a camera linked to a head tracker putted on virtual glasses.

[der8lub]

GREAT!

[nicksargeant]

Is the arduino sketch/source code available?

[andreahaku]

If you click for "more info" you can find the link to the how to. It's in my blog.

Thanks,

Andrea

[eyegoldeneye]

That would be an awesome tool in following a target...so hard to do with a joystick, even with experience..

[steammech]

were can I get an arduino

[haugeb]

fricken awesome! i just ordered the new arduino!

[thiage]

nice work!

[Skylord12345]

whoa nice

[jeppius]

Redimonis!! és molt precís :)
