The nation's first outdoor autonomous robot for food delivery, Dilly Drive, has been launched.

Woowa Brothers Corp., which runs the food delivery app Baedal Minjok, on Aug. 18 announced the start of trial runs of the gizmo at Gwanggyo Alleyway, an apartment complex in Suwon, Gyeonggi-do Province, with public facilities on the lower floors and residential areas on the upper ones.

The service is available to both visitors and residents of the complex, and the app can be used by residents and visitors to the plaza to order from restaurants and cafes in the complex.

When an order is made, the robot moves to the restaurant. A staff member puts food in the robot and presses the "Depart" button, after which the robot delivers food to the ordering customer. The customer can receive the food either on the first floor of the apartments or an outdoor table in the plaza.

The six-wheeled Dilly Drive moves at 4-5 km per hour, or about the speed of a walking person. With a light used to delivery at night, the robot can deliver about six lunchboxes or 12 drinks per trip.

Five of these robots will be run through late this month weekdays from 11 a.m. to 3 p.m. The operating hours will be gradually expanded.

Woowa Brothers plans to advance the technology for Dilly Drive and by the first half of next year, it will develop a robot that delivers in front of a customer's door.
