Could not load controller 'joint_state_controller' because controller type 'joint_state_controller/JointStateController' does not exist

[qboticslabs]

Getting this error when executing the following command !! Page number 104

$ roslaunch seven_dof_arm_gazebo seven_dof_arm_gazebo_control.launch

[qboticslabs]

Here is the solution !

Actually before running this launch file, please check Page : 100 about different types of ROS controllers and the ROS package name.

You should install this package manually. I didn't mention installation command in that page !

If you want the installation commands, you can take the following commands

$ sudo apt-get install ros-indigo-joint-state-controller : This will install joint_state_controller package

$ sudo apt-get install ros-indigo-effort-controllers : This will install Effort controller

$ sudo apt-get install ros-indigo-position-controllers : This will install position controllers
