Keeping a Downstream Module Focused During a Redesign
Sending the full street-camera feed directly into the route-selection module might provide the missing curb-boundary information, but it would force route selection to handle raw perception and decision-making at the same time. Adding a dedicated curb-line detector keeps the system modular because each part stays responsible for a narrower task.

Keeping a Downstream Module Focused During a Redesign
Why would a navigation team add a separate curb-detection module to its driving stack?
True or False: A lane-marking detector can be added so the planner receives lane-position information it did not already have.

Why Use a Boundary Detector Before Navigation?
True or False: Sending the full warehouse camera feed directly into the navigation controller is the preferred fix because it recovers missing aisle information without adding any intermediate perception step.
Adding an intermediate _____ module can turn raw road-boundary detections into a cleaner route-planning input while keeping each part of the system narrow in scope.
Why is it a bad idea to give the raw front-camera image directly to the route-selection module?
Sending the raw front-camera image straight to the route selector is the best fix when curb-line information is missing from the processing chain.
Sending raw sensor data straight into route selection breaks the principle of '_____ simplicity.'
