Member Function Documentation

configure()

hardware_interface::return_type ros2_control_demo_hardware::RRBotSystemWithSensorHardware::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 > ros2_control_demo_hardware::RRBotSystemWithSensorHardware::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 > ros2_control_demo_hardware::RRBotSystemWithSensorHardware::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.

read()

hardware_interface::return_type ros2_control_demo_hardware::RRBotSystemWithSensorHardware::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 ros2_control_demo_hardware::RRBotSystemWithSensorHardware::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 ros2_control_demo_hardware::RRBotSystemWithSensorHardware::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 ros2_control_demo_hardware::RRBotSystemWithSensorHardware::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.
