If you're ordering a takeaway in London later this year, a robot could be calling to your door.

Food delivery app Just Eat will be utilising robots built by Starship Technologies over the coming months to send orders to customers that are within a two-to-three mile radius of restaurants in the UK capital.

When greeted with the robot, consumers can input a code sent through the mobile app to open the lid and collect their food.

The self-driving robots have already completed 5,000 miles of journeys in tests across Glastonbury, Greenwich and Milton Keynes, with Starship Technologies saying they have "met over 400,000 people without a single accident."

The ground drones can "walk" at four miles per hour, using cameras and sensors to avoid obstacles and cross the road.

Here's how they operate...

David Buttress, CEO of Just Eat, commented:

"As soon as we met the Starship team, we found their passion for their product infectious.

"With scaleable innovation at the core of their business, they are the perfect partner for us at Just Eat. We can’t wait to bring the delivery robots to local high streets very soon."

Just Eat competitor Pronto will also be trialling the robots in London, with Hermes and Metro Group deploying them in the German cities of Bern, Düsseldorf and Hamburg.

Starship says that it plans to expand into other European cities and the US once testing has been completed.
