If it is not possible out of the box, can you suggest some code changes / a high-level approach?
My desired task is to teleoperate the limbs (with nao_ctrl and openni_nao), while having Choregraphe do face recognition and attention / gaze servoing with the head.
Thanks for any tips!
There's no reason why it shouldn't work, as long as you don't try to do conflicting things (but I don't know in detail how openni_nao is communicating with ROS / NaoQI). In fact, you can even connect nao_ctrl to the simulated Nao running in Choregraphe (use the correct port and IP 127.0.0.1 for NaoQI).
Of course, if you start changing Nao's leg joint angles in Choregraphe while he's walking with nao_ctrl you will produce a fall in the worst case - in the best case NaoQI won't even let you control it or will stop the walk. Same for the head: if you do gaze servoing then just don't try to change the head angles at the same time with teleoperation.
If choregraphe + nao_openni doesn't work for some reason, try running nao_openni, then from a separate bash screen try simply:
python
from naoqi import ALProxy
mp = ALProxy("ALMotion", NAO_IP, NAO_PORT)
fdp = ALProxy("ALFaceDetection", NAO_IP, NAO_PORT)
ftp = ALProxy("ALFaceTracker", NAO_IP, NAO_PORT)
mp.setStiffnesses("HeadYaw",1.0)
mp.setStiffnesses("HeadPitch",1.0)
fdp.enableTracking()
ftp.startTracking()
If this works, then we can copy it in a .py file and make it a node for nao_openni.
