roslaunch not working properly

[gsssrao]

roslaunch sangi_gazebo sangi_world.launch
is giving errors. Here are the screenshots:

So,
rosrun turtlesim turtle_teleop_key /turtle1/cmd_vel:=/sangi/cmd_vel
is also not working properly.

Output of:
rospack profile is

Look at this link : cannot launch node and then execute the following commands
rospack find controller_manager
And see if the controller_manager package is installed and can be found.
If, it can't be found, try rospack profile or install it .
If, it can be found, try running it invidually:
roscore && rosrun controller_manager controller_manager list

See, if any controllers are being listed.

Post the output of the following commands.

[gsssrao]

Ok. For rospack find controller_manager
[rospack] Error: package 'control_manager' not found
So, it is not installed.
Found the package here

So tried the debian package install:
sudo apt-get install ros-indigo-ros-control ros-indigo-ros-controllers

So, now this is the output of roslaunch:

But, teleoperator is not working properly as per arrow keys. The bot just keeps turning with wheels moving in opposite directions.

I am also getting this warning:

Then, the problem was with controller manager not installed.
From the log, there's an error that the libgazebo_ros_control plugin is not installed,
Install it by: sudo apt-get install ros-indigo-gazebo-ros-control

Now, the gazebo sim is running properly. The teleoperation is controlled by the turtlesim package which is debugged.
The problem with the teleoperation is probably because you are using a Mac. The keymappings maybe different in Mac.

Try running the turtlesim and see if that runs properly:

roscore
rosrun turtlesim turtlesim_node
rosrun turtlesim turtle_teleop_key

And see if this works properly.

If not, look at how the turtlesim node can be calibrated

I am closing this issue as of now as the gazebo and launch files are working well.

[ankithjain]

why is it showing "[turtlemimic.launch] is neither a launch file in package
[beginner_tutorials] nor is [beginner_tutorials] a launch file name
The traceback for the exception was written to the log file" when i tried
to launch a launch file ?
