I see... but from the SDK I just can get this info : - min degree & max degree - min distance & max distance - ranges array I don't know how to get the other information that I need to publish my own laser. Btw, I can't open NAO head to access hokuyo. They didn't give me the permission :(

maybe I will try to get a shot, do you mind if I use your code ? can you send it to me or put it into https://gist.github.com/ ? I need that so bad :( thank you

Hello,

I am using NAO robot right now. And I need to get the laser data, but the current NAO stack doesn't provide that. The NAO that I use is NAO with laser head. The laser is Hokuyo URG-04LX.

I want to create node which publish LaserScan topic that I get from NaoQi SDK. From the NaoQi, I can get this information : - Min/Max Degree - Min/Max Distance - Array of Distance (size about : +/- 700)

Can I use that information to create the node that publish LaserScan topic ? If yes, can someone provide me the example of Hokuyo URG-04LX laser header, angle_increment, etc ?

If it is possible, I also want the example from the Hokuyo URG-04LX in the *.bag file.

Thank you :)

Update : thanks to the comment, I already can get the information via NaoQi SDK.

I put my code here, in case someone want to use it.

:( i didn't get permission to open the head :( ... they told me to get it without open the head ... can you help me ? can I create rostopic /scan from the data I got with python NaoQi SDK ? (i can retrieve with memory.getData("Device/Laser/Value") ? please guide me :(

@AHornung : do you know how to open the head, so I can access the hokuyo directly ? thx

Ok, I will try it ... thx for the your information

so I must install ROS inside the NAO ? can't I retrieve that from the computer ?

I am using NAO "Osiris", NAO with laser on the head. I want to get the laser data so I can use SLAM with gmapping, etc.

How to get the laser data ?

Thanks

Update : I already solved that. I decided to not use directly but from the NaoQi SDK. But as mentioned in the answer, it is very slow.

If someone need the code, I put it here :

Hello everybody, currently I am using pi_tracker & openni_launch. I want to get particular depth array near from the hand.

I have tried get skeletons.position and it returns Vector3, but I don't know how to parse into 0 - 640 (width px) and 0 - 480 (height px).

Thanks :)
