Woowa Brothers Corp., South Korea’s top food delivery app operator, has launched a last-mile indoor robot food delivery service, as people increasingly prefer contactless delivery in the pandemic era.

Dilly Tower, the delivery robot, can deliver ordered food from the entrance of an apartment complex to the front door of a particular household, Woowa Brothers said on Monday.

The service, which allows the robot to come and go between the ground floor of an apartment complex to a customer’s residence without any human help, has become a reality for the first time in Korea, it said.

Woowa, the owner of the country’s No. 1 food delivery app Baedal Minjok, commonly known as Baemin, said it is initially offering the service in the Forena Yeongdeungpo Apartment Complex in western Seoul.

The residential-commercial complex has three buildings with a total of 293 households.

Once a Baemin delivery rider gets the ordered food to the entrance of the apartment building, Dilly Tower carries the food in its shelf compartment and heads for the final destination.

The delivery robot can communicate with the elevator wirelessly to pick the designated floor.

When the robot arrives at the apartment of the customer, an alert is sent to the customer through an app. After the customer enters the order number, Dilly Tower’s shelf compartment opens, and delivery is complete.

Dilly Tower can carry up to 20 kilograms and travel at a speed of up to 1.2 meters per second, according to Woowa Brothers.


Last year, Woowa Brothers ran a pilot test of an outdoor robot delivery service for food deliveries in Suwon, Gyeonggi Province.

The company and Hyundai Motor Group said in March this year they agreed to further develop delivery robots capable of traveling through various building structures and equipped with a payment service.

There is a higher technological barrier for outdoor self-driving robots than for indoor robots.

Once fully realized, the automated delivery system will allow Delidrive to travel through crowded urban streets and move between buildings with various structural features, they said.
