LoDoMus Prime and his sidekick, Dave, roam two downtown Denver parking garages every day, watching people park their cars and rush off to appointments in nearby office buildings.

If a person lingers too long, LoDoMus Prime or Dave will start a countdown: “Five, four, three, two, one.” Then the robots call their human security backup.
