What's more exciting than having a fresh hot pizza delivered to your door? How about having it brought to you by a robot? Thanks to Domino's Robotic Unit or DRU, that just became a reality! On March 8, the three-foot tall robot delivered its first pizza to some lucky residents in Brisbane, Australia.

The fully autonomous DRU is the result of a cooperation between Domino’s Pizza Australia and Marathon Robotics.The 450-pound machine that travels at a maximum speed of 12.4 miles an hour can traverse a distance of up to 12 miles and back, before requiring a battery recharge. LIDAR, a laser-based sensor technology similar to the one used in self-driving cars, enables DRU to detect and avoid obstacles, while traditional sensors, much like those used in vacuum robots ensure its path is safe as it heads to its destination.   

The robot can fit up to ten pizzas and even has a separate cold area to accommodate drink orders.To access their fond, customers have to enter the unique code provided by the company.This is not only ensures that they pick up the right pizza, but also prevents the pies from getting stolen.

Scientists expert additional DRU’s to be ready for service in their various Queensland locations within the next six months.But don’t expect these super cute robots to replace humans anytime soon.According to Domino’s the DRU still needs extensive testing, which the company believes could take up to two years.

And then there is also the issue of regulations.The public use of autonomous vehicles is still banned in most countries.But Don Meij, the CEO and Managing Director of Domino's Pizza Australia New Zealand Ltd, is not worried.He is “confident that one day DRU will become an   integral part of the Domino's family.”
