Hi,
i know there were serveral questions about this error, but they are all about the kinect connected to the turtlebot..
I have a RPLIDAR A1 connected to the turtlebot and want to run gmapping slam algorithm. I dont have a kinect connected or any other sensors. I have Ubuntu 14.04 and ROS Indigo installed on a Intel NUC build on the turtlebot.
I started this 3 commands in different terminals and a teleop command to start the Lidar scan, gmapping and RVIZ
roslaunch turtlebot_le2i rplidar_minimal.launch
roslaunch turtlebot_navigation gmapping_demo.launch
roslaunch turtlebot_rviz_launchers view_navigation.launch
It works fine, i can see the map being built in RVIZ but i get this errors in the gmapping terminal:
No matching device found.... waiting for devices. Reason: std::string openni2_wrapper::OpenNI2Driver::resolveDeviceURI(const string&) @ /tmp/binarydeb/ros-indigo-openni2-camera-0.2.7/src/openni2_driver.cpp @ 631 : Invalid device number 1, there are 0 devices connected.
