2012-05-12 16:05:18 -0500 commented question subscribing to rosout INFO

Thanks Lorenz, I tried subscribing to rosout_agg before but I cannot get anything out of it. The messages that I want to read are there (I confirmed with rostopic echo rosout_agg) but my subscriber doesn't work. Is there something wrong with this: rospy.Subscriber("rosout_agg", String, callback)?

Hi,

I'm sure this is a noob question but I looked in the wiki and in here for a long time and I could not find the answer.

Is there any way of creating a node that will subscribe to the INFO level rosout logs? Basically, I would like to do a Python node that will react to an INFO message being sent to rosout.

Thanks in advance!

Thanks for the tip. CoM seems to be very interesting but I am too much of a noob to be able to implement it yet.

I found this related file ( https://amigo.wtb.tue.nl/svn/amigo/code/tue-ros-pkg/dev/tue_perception_dev/body_detector_dev/src/body_detector.cpp ) that seems to have done this already but I cannot compile it because I'm lacking this dependency:

include "object_msgs/WorldEvidence.h"

Any idea where to find it?

Hello,

I searched the documentation and forum and did not find any answer to this question, but I might have missed something. So apologies if this is a solved issue.

I'm a very new to ROS so this might be a rather silly question. I would like to know if the openni_tracker node is able to post the user detection event and the rough user position before the PSI pose is calibrated.

I know the tracker prints that a new user is detected or gone to the terminal, but is there a topic with this information I could use?

Also, is it possible to track a user rough position before surrendering to the machine (assuming the PSI pose)?

Should I be using another node in order to do this?
