Core
AAIController
AIController is the base class of controllers for AI-controlled Pawns.
AIControllers manage the artificial intelligence for the pawns they control.

UBehaviorTreeComponent
Component used to run a behavior tree.
State Tree
UStateTreeComponent
Component used to run a state tree.
UStateTreeAIComponent
State tree component designed to be run on an AIController.
Place it on your AI Controller.
IStateTreeSchemaProvider
Implementing this interface allows derived class to override the schema used to filter valid state trees for a FStateTreeReference.
The state tree reference property needs to be marked with SchemaCanBeOverriden metatag.

Navigation

Core
UNavLocalGridManager
Manager for local navigation grids.
Builds non overlapping grid from multiple sources, that can be used later for pathfinding.
Check also: UGridPathFollowingComponent, FNavLocalGridData.
Created in UAISystem::PostInitProperties.

Path
UPathFollowingComponent
UCrowdFollowingComponent
UGridPathFollowingComponent
Path following augmented with local navigation grids. Keeps track of nearby grids and use them instead of navigation path when agent is inside. Once outside grid, regular path following is resumed. This allows creating dynamic navigation obstacles with fully static navigation (e.g. static navmesh), as long as they are minor modifications for path. Not recommended for blocking off entire corridors. Does not replace proper avoidance for dynamic obstacles!

UAIPerceptionSystem
AI Subsystem managing AI Perception through registered AI Senses between Listeners and Stimuli Sources.
Created in UAISystem::PostInitProperties.
This subsystem holds a list of Senses.
Inside UAIPerceptionSystem::Tick it calls UAISense::Tick for each Senses.
This function calls UAISense::Update, which does something different depending on the sight.
UAIPerceptionStimuliSourceComponent
Gives owning actor a way to auto-register as perception system’s sense stimuli source.
UPawnSensingComponent
Deprecated since 5.5.

UAISense
Base class of all sense classes.

UAISense_Sight
Inside UAISense_Sight::Update, UAISense_Sight::ComputeVisibility is called, which calls FAISystem::CheckIsTargetInSightCone.
