Member Function Documentation

◆ command_interface_configuration()

controller_interface::InterfaceConfiguration ros2_control_demo_example_7::RobotController::command_interface_configuration ( ) const

overridevirtual

Get configuration for controller's required command interfaces.

Method used by the controller_manager to get the set of command interfaces used by the controller. Each controller can use individual method to determine interface names that in simples case have the following format: <joint>/<interface>. The method is called only in inactive or active state, i.e., on_configure has to be called first. The configuration is used to check if controller can be activated and to claim interfaces from hardware. The claimed interfaces are populated in the command_interfaces_ member.

Returns: configuration of command interfaces.

Implements controller_interface::ControllerInterfaceBase.

◆ state_interface_configuration()

controller_interface::InterfaceConfiguration ros2_control_demo_example_7::RobotController::state_interface_configuration ( ) const

overridevirtual

Get configuration for controller's required state interfaces.

Method used by the controller_manager to get the set of state interface used by the controller. Each controller can use individual method to determine interface names that in simples case have the following format: <joint>/<interface>. The method is called only in inactive or active state, i.e., on_configure has to be called first. The configuration is used to check if controller can be activated and to claim interfaces from hardware. The claimed interfaces are populated in the state_interfaces_ member.

Returns: configuration of state interfaces.

Implements controller_interface::ControllerInterfaceBase.

◆ update()

controller_interface::return_type ros2_control_demo_example_7::RobotController::update	(	const rclcpp::Time &	time,
		const rclcpp::Duration &	period
	)

overridevirtual

Control step update. Command interfaces are updated based on on reference inputs and current states. The method called in the (real-time) control loop.

Parameters

[in]	time	The time at the start of this control loop iteration
[in]	period	The measured time since the last control loop iteration

Returns: return_type::OK if update is successfully, otherwise return_type::ERROR.

Implements controller_interface::ControllerInterfaceBase.
