Sensors compound a specific family of actors quite diverse and unique. They are normally spawned as attachment/sons of a vehicle (take a look at carla.World to learn about actor spawning). Sensors are thoroughly designed to retrieve different types of data that they are listening to. The data they receive is shaped as different subclasses inherited from carla.SensorData (depending on the sensor).
Most sensors can be divided in two groups:those receiving data on every tick (cameras, point clouds and some specific sensors) and those who only receive under certain circumstances (trigger detectors). CARLA provides a specific set of sensors and their blueprint can be found in carla.BlueprintLibrary. All the information on their preferences and settlement can be found [here](ref_sensors.md), but the list of those available in CARLA so far goes as follows:<br>
The function the sensor will be calling to every time a new measurement is received. This function needs for an argument containing an object type carla.SensorData to work with.
This sensor works a bit differently than the rest. Take look at the [specific documentation](adv_rss.md), and the [rss sensor reference](ref_sensors.md#rss-sensor) to gain full understanding of it.
The RSS sensor uses world information, and a [RSS library](https://github.com/intel/ad-rss-lib) to make safety checks on a vehicle. The output retrieved by the sensor is a carla.RssResponse. This will be used by a carla.RssRestrictor to modify a carla.VehicleControl before applying it to a vehicle.
States the [RSS parameters](https://intel.github.io/ad-rss-lib/ad_rss/Appendix-ParameterDiscussion/) that the sensor will consider for the ego vehicle if no actor constellation callback is registered.
States the [RSS parameters](https://intel.github.io/ad-rss-lib/ad_rss/Appendix-ParameterDiscussion/) that the sensor will consider for the rest of vehicles if no actor constellation callback is registered.
States the [RSS parameters](https://intel.github.io/ad-rss-lib/ad_rss/Appendix-ParameterDiscussion/) that the sensor will consider for pedestrians if no actor constellation callback is registered.
Discards the current route. If there are targets remaining in **<font color="#f8805a">routing_targets</font>**, creates a new route using those. Otherwise, a new route is created at random.
The function to be called whenever a RSS situation is about to be calculated.

Register a callback to customize a carla.RssActorConstellationResult. By this callback the settings of RSS parameters are done per actor constellation and the settings (ego_vehicle_dynamics, other_vehicle_dynamics and pedestrian_dynamics) have no effect.
These objects apply restrictions to a carla.VehicleControl. It is part of the CARLA implementation of the [C++ Library for Responsibility Sensitive Safety](https://github.com/intel/ad-rss-lib). This class works hand in hand with a [rss sensor](ref_sensors.md#rss-sensor), which provides the data of the restrictions to be applied.
Enum declaration used in carla.RssSensor to enable or disable the [stay on road](https://intel.github.io/ad-rss-lib/ad_rss_map_integration/HandleRoadBoundaries/) feature. In summary, this feature considers the road boundaries as virtual objects. The minimum safety distance check is applied to these virtual walls, in order to make sure the vehicle does not drive off the road.
