- class invertedai.common.AgentAttributes(*, length: float, width: float, rear_axis_offset: float)[source]#
Static attributes of the agent, which don’t change over the course of a simulation. We assume every agent is a rectangle obeying a kinematic bicycle model.
See also
- length: float#
Longitudinal extent of the agent, in meters.
- rear_axis_offset: float#
Distance from the agent’s center to its rear axis in meters. Determines motion constraints.
- tolist()[source]#
Convert AgentAttributes to a flattened list of agent attributes in this order: [length, width, rear_axis_offset]
- width: float#
Lateral extent of the agent, in meters.
- class invertedai.common.AgentState(*, center: Point, orientation: float, speed: float)[source]#
The current or predicted state of a given agent at a given point.

- classmethod fromlist(l)[source]#
Build AgentState from a list with this order: [x, y, orientation, speed]
- orientation: float#
The direction the agent is facing, in radians with 0 pointing along x and pi/2 pointing along y.
- speed: float#
In meters per second, negative if the agent is reversing.
- class invertedai.common.Image(*, encoded_image: List[int])[source]#
Images sent through the API in their encoded format. Decoding the images requires additional dependencies on top of what invertedai uses.
- class invertedai.common.InfractionIndicators(*, collisions: bool, offroad: bool, wrong_way: bool)[source]#
Infractions committed by a given agent, as returned from
iai.drive()
.- collisions: bool#
True if the agent’s bounding box overlaps with another agent’s bounding box.
- offroad: bool#
True if the agent is outside the designated driveable area specified by the map.
- wrong_way: bool#
True if the cross product of the agent’s and its lanelet’s directions is negative.
- class invertedai.common.LocationMap(*, encoded_map: str, origin: Origin)[source]#
Serializable representation of a Lanelet2 map and the corresponding origin. To reconstruct the map locally, save the OSM file to disk and load it with the UTM projector using the origin provided here. This projection defines the canonical coordinate frame of the map. Origin of the map, specified as a pair of latitude and longitude coordinates. Allows for geolocation of the map and can be used with a UTM projector to construct the Lanelet2 map object in the canonical coordinate frame.
- class invertedai.common.Point(*, x: float, y: float)[source]#
2D coordinates of a point in a given location. Each location comes with a canonical coordinate system, where the distance units are meters.

Recurrent state used in
iai.drive()
. It should not be modified, but rather passed along as received.
- class invertedai.common.StaticMapActor(*, actor_id: int, agent_type: str, center: Point, orientation: float, length: Optional[float] = None, width: Optional[float] = None, dependant: Optional[List[int]] = None)[source]#
Specifies a traffic light placement. We represent traffic lights as rectangular bounding boxes of the associated stop lines, with orientation matching the direction of traffic going through it.
