export_state_interfaces()

std::vector< hardware_interface::StateInterface > ros2_control_demo_example_14::RRBotSensorPositionFeedback::export_state_interfaces ( )

overridevirtual

Exports all state interfaces for this hardware interface.

The state interfaces have to be created and transferred according to the hardware 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::SensorInterface.

get_clock()

rclcpp::Clock::SharedPtr ros2_control_demo_example_14::RRBotSensorPositionFeedback::get_clock ( ) const

inline

Get the clock of the SensorInterface.

Returns

clock of the SensorInterface.

get_logger()

rclcpp::Logger ros2_control_demo_example_14::RRBotSensorPositionFeedback::get_logger ( ) const

inline

Get the logger of the SensorInterface.

Returns

logger of the SensorInterface.

on_init()

hardware_interface::CallbackReturn ros2_control_demo_example_14::RRBotSensorPositionFeedback::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::SensorInterface.

read()

hardware_interface::return_type ros2_control_demo_example_14::RRBotSensorPositionFeedback::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::SensorInterface.
