For those who's interested: solved by switching to openni with drivers installed from https://github.com/avin2/SensorKinect

2014-12-24 02:57:06 -0500 answered a question Is it possible to have a Service node in Python and the Client node in C++?

Yes. ROS is a multi-lingual OS, the service-client specification is at the messaging layer. P2P communication occurs in XML-RPC. So you can just write your code in any language supported and let the mid-layer handle this for you. You can take a look at the original paper: http://www.willowgarage.com/papers/ro...

Hope this helps.

2014-12-24 02:52:31 -0500 answered a question kinect_aux indexing kinect based on serial no.
boost::shared_ptr<FreenectDevice> device_;

then

std::string serial_number = device_->getSerialNumber();

take a look at how freenect_stack has implemented this: https://github.com/piyushk/freenect_s...

2014-12-24 02:52:30 -0500 asked a question freenect_launch will always stop and flush when I launch rgbdslam

I am using ROS hydro on ubuntu 12.04 LTS. The problem is, since I'm using freenect to get depth and RGB images for rgbdslam, the freenect node will be okay if I leave it alone without any subscriber. But soon after I started processing the image in the rgbdslam node, the freenect node will stop and fall to a dead loop of:

[ INFO] [1419407643.570524704]: Device timed out. Flushing device.
[ INFO] [1419407643.570749230]: Starting a 3s RGB and Depth stream flush.
...

I'm using Kinect 1, and ubuntu is running in Parallels Desktop 10 with Mac OS X. I don't know what has caused this problem, anyone can help me? Thanks in advance.
