CollisionGuardNode
ASIL C

Attribute	Value
id	com.example.stig.components.collisionguardnode.context.collisionGuardNode
name	Collision guard node
description	ROS 2 software component that detects obstacles in camera images of the robot's forward travel corridor and publishes brake_request. Input plausibility and frame-continuity checks are proposed safety mechanisms; their detection coverage remains unestablished.
