Hyundai Motor Group Robots Get Rolling with Pilot Programs to Advance Last-mile Delivery

Hyundai Motor Group (the Group) has started two pilot delivery service programs using autonomous robots based on its Plug & Drive (PnD) modular platform at a hotel and a residential-commercial
complex located in the outskirts of Seoul.
The delivery robot consists of a storage unit integrated on top of a PnD
driving unit. Alongside the loading box used to deliver items, a connected
screen displays information for customers.
First shown at CES 2022, the Group’s PnD modular platform is an all-in-one
single wheel unit that combines intelligent steering, braking, in-wheel electric
drive and suspension hardware, including a steering actuator for 360-degree,
holonomic rotation. It moves autonomously with the aid of LiDAR and camera
sensors. An integrated storage unit allows the robot to transport products to
customers.
By adding the autonomous driving capability, the PnD-based robot can find
the optimal route within the area to deliver packages to recipients. It can
recognize and avoid fixed and moving objects and drive smoothly, providing a
fast delivery time.
“PnD-based delivery robots allow quicker delivery times with improved safety
through the use of autonomous driving technology, including fast obstacle
avoidance capabilities,” said Dong Jin Hyun, Head of Robotics LAB of
Hyundai Motor Group. “We plan to keep upgrading mobility services,
convenience, safety and affordability for customers through our pilot
programs.”
Rolling Hills Hotel, one of the businesses participating in the Group’s pilot
programs, is using the robot for room service from 8 p.m. to 10 p.m. daily,
delivering amenities, food and drinks. Hotel guests can place their room
service orders using Kakao Talk, a popular messaging app, without installing
any additional apps, and use real-time tracking to follow the delivery’s
progress.
The robot in service at the hotel uses a deep learning-based algorithm to

recognize the surrounding environment and people. When the robot arrives at
the room it recognizes the opening of the door, and once it perceives the
recipient, it automatically opens the storage compartment for them.
The robot can communicate appropriate screen messages and in a befitting
tone of voice based on the recipient. In addition, when moving between
floors, the unit can determine the number of people boarding an elevator and
wait for the next elevator if the first one is crowded.
The autonomous driving robot is also adept at avoiding obstacles and
collisions, even in narrow hotel corridors, and can move between floors
without human help due to electronic connectivity with the elevators, enabling
it to deliver goods along an optimal route.
The Group has also partnered with Woowa Brothers, a Korean delivery
company operating the Baemin food delivery app, since March 2021 to
further advance the technology and service capabilities of last-mile outdoor
delivery robots.
As part of a new program with Woowa Brothers, the Group’s delivery robot is
being used for door-to-door (D2D) food services at a residential/commercial
complex in the outskirts of Seoul. After a customer places an online order
through Baemin, the robot finds the exact item at a shopping center
connected to a residential-commercial complex and delivers it to the
customer’s front door.
To enable the service, the Group uses wireless communication to access
communal front doors and elevators, an issue which was previously an
obstacle to commercializing robot delivery service. The service robot can
enter the apartment complex, access upper floors through the elevator control
system and deliver food to the customer’s home.
The technology enabling service robots to move autonomously indoors and
outdoors and deliver food without human assistance has created a game-

changing last-mile delivery innovation that is attracting significant attention
from the logistics and retail industries. The Group expects last-mile delivery
robots to greatly increase the efficiency of the entire delivery process.
Based on the results of these pilot programs, the Group plans to upgrade its
PnD-based delivery robot services and gradually expand the number of
robots and their operating hours. It also plans to expand its business into
commercial areas that require delivery services to connect with customers.
