typedef rclcpp_lifecycle::node_interfaces::LifecycleNodeInterface::CallbackReturn hardware_interface::CallbackReturn |
Virtual Class to implement when integrating a 1 DoF actuator into ros2_control.
Virtual Class to implement when integrating a complex system into ros2_control.
Virtual Class to implement when integrating a stand-alone sensor into ros2_control.
The typical examples are conveyors or motors.
Methods return values have type rclcpp_lifecycle::node_interfaces::LifecycleNodeInterface::CallbackReturn with the following meaning:
The hardware ends after each method in a state with the following meaning:
UNCONFIGURED (on_init, on_cleanup): Hardware is initialized but communication is not started and therefore no interface is available.
INACTIVE (on_configure, on_deactivate): Communication with the hardware is started and it is configured. States can be read and non-movement hardware interfaces commanded. Hardware interfaces for movement will NOT be available. Those interfaces are: HW_IF_POSITION, HW_IF_VELOCITY, HW_IF_ACCELERATION, and HW_IF_EFFORT.
FINALIZED (on_shutdown): Hardware interface is ready for unloading/destruction. Allocated memory is cleaned up.
ACTIVE (on_activate): Power circuits of hardware are active and hardware can be moved, e.g., brakes are disabled. Command interfaces for movement are available and have to be accepted. Those interfaces are: HW_IF_POSITION, HW_IF_VELOCITY, HW_IF_ACCELERATION, and HW_IF_EFFORT.
The typical examples are Force-Torque Sensor (FTS), Interial Measurement Unit (IMU).

The common examples for these types of hardware are multi-joint systems with or without sensors such as industrial or humanoid robots.
