turtlebot.eu power board and kinect
Hey,
I have a question regarding turtlebot.eu power board. I don't have any external battery so everything is power through roomba's battery. Kinect is connected on 12v dc power connector (spec at max 350mA) on the power board.
Everything works normally. I can control roomba, get video feed from kinect cameras. But I do have a problem with pointcloud data. It starts completely normal. I am receiving pointcloud normally for approximately a minute. After that it just stops. No error messages, the image just freezes. Roomba works all the time withouth problem (teleop, dashboard). It seems like that the openni freezes. Is it possible that kinect doesn't get enought power, that I should use external battery? Or maybe is there a problem with openni kinect driver?
The same problem is when I try to build a SLAM map. It works normally for about a minute then the laser topic stops posting. Since laser is build from pointcloud I think problems are connected.
Also I notice, when I watch only IR stream from kinect, the IR light on kinect flashes slowly. It is not constantly lit. Is that normal? Like that the IR camera is switching between ON and OFF.
Does anybody have the same problem? I start turtlebot with
roslaunch turtlebot_bringup minimal.launch
and start openni with
roslaunch openni_launch openni.launch
Then I run
rosrun rviz rviz
to get the image.
Thank you for your help.
