hello peeps

im new to ROS. So, i was following turtlebot simulation tutorials to create map. I manage to launch gazebo. Then when i try to launch rviz i get error.

the command i use

roslaunch turtlebot_rviz_launchers view_navigation.launch

the error i get

[view_navigation.launch] is neither a launch file in package [turtlebot_rviz_launchers] nor is [turtlebot_rviz_launchers] a launch file name
The traceback for the exception was written to the log file

can anyone help here? I already execute source /opt/ros/indigo/setup.bash but still cant run rviz

im using ubuntu 14.04 and ROS INDIGO

hi everyone im new in ubuntu and currently learning to understand ROS. im working on a project which required ROS to program turtbot for navigation. the problem is I dont know where and what to start. im just following the ROS tutorial provided. can anyone enlighten me on how and what should i do first.what is the step from creating workspace to programming turtlebot.

im so lost here :(

hi everyone. i need help on creating yaml file. i have to create a yaml file from an image(map of surrounding) and then used the yaml file for turtlebot navigation. anyone know where can i start?is it very difficult to be done?i have no basic of programming. please help

noted..thanks for the information..by the way, is it possible to create map (by editing the yaml file) straight away from a picture or real map?i mean translating the picture into yaml file by using some sort of algorithm..is it do able?

ohh silly me..i run the gmapping on workstation.should run on turtlebot..;)

so i was following the SLAM Map Building with TurtleBot. The problem is there is no map received error in rviz. anyone know how to overcome this problem?
