Member Function Documentation

◆ configure()

hardware_interface::return_type ign_ros2_control::IgnitionSystem::configure ( const hardware_interface::HardwareInfo & system_info )

overridevirtual

Configuration of the system from data parsed from the robot's URDF.

Parameters

[in] system_info structure with data from URDF.

Returns: return_type::OK if required data are provided and can be parsed, return_type::ERROR otherwise.

Reimplemented from hardware_interface::BaseInterface< hardware_interface::SystemInterface >.

◆ export_command_interfaces()

std::vector< hardware_interface::CommandInterface > ign_ros2_control::IgnitionSystem::export_command_interfaces ( )

overridevirtual

Exports all command interfaces for this system.

The command interfaces have to be created and transferred according to the system info passed in for the configuration.

Note the ownership over the state interfaces is transferred to the caller.

Returns: vector of command interfaces

Implements hardware_interface::SystemInterface.

◆ export_state_interfaces()

std::vector< hardware_interface::StateInterface > ign_ros2_control::IgnitionSystem::export_state_interfaces ( )

overridevirtual

Exports all state interfaces for this system.

The state interfaces have to be created and transferred according to the system info passed in for the configuration.

Note the ownership over the state interfaces is transferred to the caller.

Returns: vector of state interfaces

Implements hardware_interface::SystemInterface.

◆ initSim()

bool ign_ros2_control::IgnitionSystem::initSim	(	rclcpp::Node::SharedPtr &	model_nh,
		std::map< std::string, ignition::gazebo::Entity > &	joints,
		const hardware_interface::HardwareInfo &	hardware_info,
		ignition::gazebo::EntityComponentManager &	_ecm,
		int &	update_rate
	)

overridevirtual

Initialize the system interface param[in] model_nh Pointer to the ros2 node param[in] joints Map with the name of the joint as the key and the value is related with the entity in Gazebo param[in] hardware_info structure with data from URDF. param[in] _ecm Entity-component manager. param[in] update_rate controller update rate.

Implements ign_ros2_control::IgnitionSystemInterface.

◆ read()

hardware_interface::return_type ign_ros2_control::IgnitionSystem::read ( )

overridevirtual

Read the current state values from the actuators and sensors within the system.

The data readings from the physical hardware has to be updated and reflected accordingly in the exported state interfaces. That is, the data pointed by the interfaces shall be updated.

Returns: return_type::OK if the read was successful, return_type::ERROR otherwise.

Implements hardware_interface::SystemInterface.

◆ start()

hardware_interface::return_type ign_ros2_control::IgnitionSystem::start ( )

overridevirtual

Start exchange data with the hardware.

Returns: return_type:OK if everything worked as expected, return_type::ERROR otherwise.

Implements hardware_interface::SystemInterface.

◆ stop()

hardware_interface::return_type ign_ros2_control::IgnitionSystem::stop ( )

overridevirtual

Stop exchange data with the hardware.

Returns: return_type:OK if everything worked as expected, return_type::ERROR otherwise.

Implements hardware_interface::SystemInterface.

◆ write()

hardware_interface::return_type ign_ros2_control::IgnitionSystem::write ( )

overridevirtual

Write the current command values to the actuator within the system.

The physical hardware shall be updated with the latest value from the exported command interfaces.

Returns: return_type::OK if the read was successful, return_type::ERROR otherwise.

Implements hardware_interface::SystemInterface.
