Alright. Hi guys! We are now gonna have a look at how to get the NAO do object recognition so as always we just check that were connected to him so there’s NAO robot sitting down and just gonna go into the box yep he’s fully connected.
So first thing we have to do is we need to see the camera so we can see the object that the NAO is going to learn this if we go to view and if we go to video monitor and click that this is the camera that the NAO is seeing through so I’m just gonna make this bigger so you can see it lot bigger there you go perfect.
Now all we have to do is first click this box up here which is the new vision recognition database so were creating a new database of objects for NAO to see. So click that we can see permissions just click yes and were creating a new database so now this is grayed out so if its grayed already that’s fine if its not please click see through that.
Now if I wave my hand in front of the camera you can see there it is the NAO is recognizing my hand in front of it. If I hit pause, it’s just a still image so I’m not sure if you can see this in on this camera view. Then if you hit play then this is a live stream and this is what we wanna see so we can pick up objects again I’ll put my hand in front of it and you can see me there now if you wanna use the other camera so this is now stop camera just quickly if you go into vision and scroll down to select camera bring that in and if we connect it to the bottom that’s top and that’s the bottom and hit play there we go a bit slow there but we have the bottom camera so again I’ll wave my hand round there so you can see it there it is that seems see the bottom camera and you can see his hands here but with that one moving on with the top so were gonna cut this to needle and we gonna put the needle back to the top camera and hit play again so we just got the top camera that were actually working with and were back there again brilliant brilliant so lets gonna delete that so we could show you that so we now gonna use the learn button to get the NAO camera to recognize the object learn button is this one here see it fast up learn. Now, if we put the object in front of the NAO I’ve got a picture of NAO so you can see what I’m looking at. There he is. Just trying up there we go. So this is what we want him to learn now when we hit the learn button it gives me 4 seconds to get the object in front of him that he’s going to learn. So next going back to this button here what I’m talking about lets hit it let’s bring it in brilliant we got it just what we want. Now as soon as you hit the button and it captures the image then you can click on to the image and it will automatically bring up a selection tool so you can actually cut out the image that you want so coz its not a simple square were just gonna cut four squares and there we go we got our image that we want. It pops up the object tags box and we just write what we want so we want picture of NAO and side is the front view you can put in description if you want in here and this is other option as well. But we’ll stick to that for now for this tutorial and okay congratulations has been added to your local database. Don’t forget to send your local database to the robot yes so at this stage you can add as many objects as you want so for this time we’ll just do one but you can go on and add how objects for NAO to recognize doing the same steps as up to same?...

[@alittleguitarist7819]

i have done vision recognition for the single object but i m unable to do it with multiple objects, can you help me out ,how can we make a program for multiple objects to the vision recognition.

[@JazAverlo]

hello, may I ask you a question? how to use the API ALVisionRecognitionProxy::learnFromFile and ALVisionRecognitionProxy::detectFromFile to let NAO to do the Object Recognition?

[@blind_neighbourhoodNerd]

Great tutorial. Cheers!

[@lauryrodriguez7229]

Hello, can I feed it images of multiple objects?

[@deenarko6991]

Everytime it takes more time to get into listening mode.. What's the reason??

[@MarcoW125]

hi, i am trying to teach Pepper to detect some objects with tensorflow, i got object detection api ready but i dont know how to connect my laptop with pepper so i can use tensorflow. Doe you know how this is working ?

[@deenarko6991]

Is there any trick to get NAO into listening mode??? @philip english

[@kathrinemadsen7133]

Hi RoboPhil. I have choreograph 2.1.4.13 as well as Naoqi 2.1.4.13 and it does not work :-/ The flow stops in the vision reco box. What to do?

[@RoboPhil]

+Kathrine Madsen Hi Kathrine, It looks like i may need to do a new Tutorial for this one, as I have come across this a few times :-s . I will add it to my list :-)

[@RoboPhil]

Hi Katherine Are you still using your NAO Robot?

[@RoboPhil]

Can you email me here [e-mail]

[@kurtirving8349]

Yeah, I even tried using the Vision Recog Box and it's still broken after all these years... SoftBank also redid their site recently and made a huge mess of things, so it's impossible right now to check the forum properly.

[@enriquemorangarrido1915]

can you please record an advanced object recognition tutorial?

[@filipstevens6263]

Awesome video, could you also make a tutorial for facial recognition please Robo Phil?

[@RoboPhil]

filip stevens Hi Filip, I am currently working on a new load of tutorials and this will be in there. :-)

[@modsmilzo644]

Dude but how to track the object and pick if the object is on the floor , thats i want to learn :)

[@RoboPhil]

MoD Smilzo Hi MoD, I have added, to my list. :-)

[@fernsulantay]

MoD thats what I wwant to do too. Were you able to do it?

[@modsmilzo644]

Hey it was really hard to do , but if u need some help u can write me.

[@flawlessR42]

Hey, i know its one year ago but i am working with a Softbank robot (Pepper) and i want that as you write he follows a object he recognized but how do i do it. i would appreciate your help

[@rinitaasani93]

Hi RoboPhil! Thank for the video:) I have Naoqi version 2.1.4 and Choregraphe version 2.1.2. I did all the steps, but it doesn't recognize at all the object. Is the problem that version of Naoqi and Choreographe are not the same?

[@RoboPhil]

+Rinita Asani Hi Rinita, many thanks for your comment. I think you are right, if you are running a different version it could be the reason why it is not working. Keep me posted, if you manage to solve it? :-)

[@RoboPhil]

Hi are you still using the NAO Robot?. Can you email me here [e-mail]

[@郭孟勳-h3b]

I tried to do the same thing. But it didn't work at all. Can you tell me which version of your Nao and Choregraphe ps.My version is 2.1.4 for both

[@RoboPhil]

+郭孟勳 Hi , I know this works upto 2.1.2, I am not sure about 2.1.4. :-s .I will keep an eye on things and if I can 't get it to work on the new version I will do an update tutorial :-) . Thanks Phil

[@RoboPhil]

Hi moh you, sorry to hear this is not working :-s. I have done this many times, so it should work fine. Are there any errors codes that come up? ☺ :-)

[@arshantohi]

Would you be able to do this while connecting to a virtual robot?

[@azkenteknic2053]

no

[@taraandrews5405]

How much is the software to program the NAO?

[@yenle874]

Hi Phil, I have Chelographe 2.1.4.13 and try that nao recognites objects, but it does not work with small objects. I see the objects in database, that be recognited, but nao can not dectect them. so what should I ? Anyway you can make a tutorial how to regconite objects with nao using python =) Thanks a lot!!

[@mohyou9551]

please can you help me?I did the exact same steps you did but the robot still doesn't recognize the object I am showing him

[@RoboPhil]

+moh you Hi moh you, sorry to hear this is not working :-s. I have done this many times, so it should work fine. Are there any errors codes that come up? ☺ :-)

[@RoboPhil]

Can you send me any screen shots to [e-mail]? ☺ . Phil

[@mohyou9551]

+Robo Phil nothing it just doesn't recognize it. does modifying the monitor camera settings affect it?

[@RoboPhil]

+moh you hi moh you, what sort of modifications have you done? ☺

[@mohyou9551]

+Robo Phil the monitor program that comes with choregraphe. every time I tick vision recognition it doesn't save the setting

[@mohyou9551]

for everyone that this did not work with. It is probably because your nao's software is 2.1.3 If so you have to upgrade your nao to 2.1.4.13 which fixes this bug.

[@RoboPhil]

+moh you Thanks Moh, I really appreciate your help with this one :-) . Many Thanks Phil

[@mohyou9551]

:D

[@fernsulantay]

My software is 2.1.4.13 already but my robot doesnt recognize the object!! Is there objects easier to recognize? I was trying to make him recognize my phone against a white wall. HELP please

[@mohyou9551]

Fernanda Sulantay I made him recognise a red ball and a small toy robot and it worked out pretty well. I think your phone didn't work cause of the reflective screen. Try with a different objective and see the results.

[@PeymanJahani]

Thanks for this tutorial. I wonder why do we need to have a stop feedback on say box (7:16)?

[@RoboPhil]

Peyman Jahani Hi Peyman, thanks for your question. This is so the robot only says the word once. Many Thanks :-)
