◆ export_command_interfaces()

std::vector< hardware_interface::CommandInterface > ros2_control_demo_example_14::RRBotActuatorWithoutFeedback::export_command_interfaces ( )
overridevirtual

Exports all command interfaces for this hardware interface.

Old way of exporting the CommandInterfaces. If a empty vector is returned then the on_export_command_interfaces() method is called. If a vector with CommandInterfaces is returned then the exporting of the CommandInterfaces is only done with this function and the ownership is transferred to the resource manager. The set_command(...), get_command(...), ..., can then not be used.

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

Returns
vector of state interfaces

Reimplemented from hardware_interface::ActuatorInterface.

◆ export_state_interfaces()

std::vector< hardware_interface::StateInterface > ros2_control_demo_example_14::RRBotActuatorWithoutFeedback::export_state_interfaces ( )
overridevirtual

Exports all state interfaces for this hardware interface.

Old way of exporting the StateInterfaces. If a empty vector is returned then the on_export_state_interfaces() method is called. If a vector with StateInterfaces is returned then the exporting of the StateInterfaces is only done with this function and the ownership is transferred to the resource manager. The set_command(...), get_command(...), ..., can then not be used.

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

Returns
vector of state interfaces

Reimplemented from hardware_interface::ActuatorInterface.

◆ on_init()

hardware_interface::CallbackReturn ros2_control_demo_example_14::RRBotActuatorWithoutFeedback::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_infostructure 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::ActuatorInterface.

◆ read()

hardware_interface::return_type ros2_control_demo_example_14::RRBotActuatorWithoutFeedback::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]timeThe time at the start of this control loop iteration
[in]periodThe 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::ActuatorInterface.

◆ write()

hardware_interface::return_type ros2_control_demo_example_14::RRBotActuatorWithoutFeedback::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]timeThe time at the start of this control loop iteration
[in]periodThe 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::ActuatorInterface.
