Detailed Description

template<class T>
class controller_interface::Controller< T >

Controller with a specific hardware interface

Template Parameters
TThe hardware interface type used by this controller. This enforces semantic compatibility between the controller and the hardware it's meant to control.

Member Function Documentation

template<class T>
std::string controller_interface::Controller< T >::getHardwareInterfaceType ( ) const
inlineprotected

Get the name of this controller's hardware interface type.

Definition at line 136 of file controller.h.

template<class T>
virtual bool controller_interface::Controller< T >::init ( T *  ,
ros::NodeHandle  
)
inlinevirtual

The init function is called to initialize the controller from a non-realtime thread with a pointer to the hardware interface, itself, instead of a pointer to a RobotHW.

Parameters
hwThe specific hardware interface used by this controller.
controller_nhA NodeHandle in the namespace from which the controller should read its configuration, and where it should set up its ROS interface.
Returns
True if initialization was successful and the controller is ready to be started.

Definition at line 71 of file controller.h.

template<class T>
virtual bool controller_interface::Controller< T >::init ( T *  ,
ros::NodeHandle ,
ros::NodeHandle  
)
inlinevirtual

The init function is called to initialize the controller from a non-realtime thread with a pointer to the hardware interface, itself, instead of a pointer to a RobotHW.

Parameters
hwThe specific hardware interface used by this controller.
root_nhA NodeHandle in the root of the controller manager namespace. This is where the ROS interfaces are setup (publishers, subscribers, services).
controller_nhA NodeHandle in the namespace of the controller. This is where the controller-specific configuration resides.
Returns
True if initialization was successful and the controller is ready to be started.

Definition at line 88 of file controller.h.

template<class T>
virtual bool controller_interface::Controller< T >::initRequest ( hardware_interface::RobotHW robot_hw,
ros::NodeHandle root_nh,
ros::NodeHandle controller_nh,
ClaimedResources claimed_resources 
)
inlineprotectedvirtual

Initialize the controller from a RobotHW pointer.

This calls init with the hardware interface for this controller if it can extract the correct interface from robot_hw.

Implements controller_interface::ControllerBase.
