◆ on_init()

hardware_interface::CallbackReturn ros2_control_demo_example_12::RRBotSystemPositionOnlyHardware::on_init ( const hardware_interface::HardwareInfo & hardware_info )

overridevirtual

Initialization of the hardware interface from data parsed from the robot's URDF.

Parameters

[in] hardware_info structure with data from URDF.

Returns: CallbackReturn::SUCCESS if required data are provided and can be parsed.; CallbackReturn::ERROR if any error happens or data are missing.

Reimplemented from hardware_interface::SystemInterface.

◆ read()

hardware_interface::return_type ros2_control_demo_example_12::RRBotSystemPositionOnlyHardware::read	(	const rclcpp::Time &	time,
		const rclcpp::Duration &	period
	)

overridevirtual

Read the current state values from the actuator.

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.

Parameters

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

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

Implements hardware_interface::SystemInterface.

◆ write()

hardware_interface::return_type ros2_control_demo_example_12::RRBotSystemPositionOnlyHardware::write	(	const rclcpp::Time &	time,
		const rclcpp::Duration &	period
	)

overridevirtual

Write the current command values to the actuator.

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

Parameters

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

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

Implements hardware_interface::SystemInterface.
