No matching devices founded error for gmapping_demo.launch (turtlebot)
Note: I solved the problem. It seems I set environment paths wrong for Kinect as described here.
I am encountering with the following error when I try to run :
roslaunch turtlebot_navigation gmapping_demo.launch
Error:
[ INFO] [1426701074.584654164]: No matching device found.... waiting for devices. Reason: std::string openni2_wrapper::OpenNI2Driver::resolveDeviceURI(const string&) @ /tmp/buildd/ros-indigo-openni2-camera-0.2.3-0trusty-20150221-1448/src/openni2_driver.cpp @ 623 : Invalid device number 1, there are 0 devices connected.
Strange thing when I run :
roslaunch openni_launch openni.launch
I don't get any errors and I am able to see rgb and depth output of kinect sensor.
I think it shows that I installed Kinect driver properly. But there is something wrong with gmapping_demo that lets not to find Kinect on the USB ports.
As suggested here I installed freenect_launch and run :
roslaunch freenect_launch freenect.launch
And now I am able to get rgb and depth data on Rviz from TurtleBot's Kinect (workstation) Because gmapping_demo uses openni_launch as default I need to change launch file but not quite sure it will let the gmapping_demo use freenect_launch.
My setup : Asus netbook X201E for TurtleBot Lenovo E440 for workstation Both have Ubuntu 14.04.02 with Indigo
