Currently Domino's Australia is testing the DRU, Domino’s Robotic Unit. It’s an automated delivery bot that can roam the streets all by itself, and bring you your order with no human intervention.
To avoid hungry hoodlums stealing your food in transit, the compartment can only be unlocked with a smartphone app or a special code you’re given when you place your order. The company already tested the bot with a few customers in one neighborhood, and everything went well.
