Automation task
A baggage handling system at an airport is used to distribute pieces of baggage. When a
flight lands, all baggage is loaded onto the baggage handling system. The baggage passes
through a scanner at high speed. The scanner checks the destination of the baggage:
● If a piece of baggage has reached its destination airport, the baggage handling system
forwards it directly to baggage claim.
● If a piece of baggage has not reached its final destination, the system immediately
redirects it towards the connecting flight.
