export_command_interfaces()

std::vector< hardware_interface::CommandInterface > ros2_control_demo_hardware::RRBotModularJoint::export_command_interfaces ( )

overridevirtual

Exports all command interfaces for this hardware interface.

The command 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 command interfaces

Implements hardware_interface::ActuatorInterface.

export_state_interfaces()

std::vector< hardware_interface::StateInterface > ros2_control_demo_hardware::RRBotModularJoint::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::ActuatorInterface.

on_init()

CallbackReturn ros2_control_demo_hardware::RRBotModularJoint::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::ActuatorInterface.

read()

hardware_interface::return_type ros2_control_demo_hardware::RRBotModularJoint::read ( )

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.

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_hardware::RRBotModularJoint::write ( )

overridevirtual

Write the current command values to the actuator.

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::ActuatorInterface.
