Deep-learning technology enables PnD-based robot to recognize customers; autonomous driving technology and connectivity with elevators enables movement between floors without human help
SEOUL – 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 has a storage unit integrated on top of a PnD driving unit. Alongside the loading box used to deliver items, a connected screen displays customer information.
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 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 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, uses 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 door’s opening, and once it perceives the recipient, it automatically opens the storage compartment for them.
The robot can communicate appropriate screen messages in a befitting tone 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. It 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 advance further 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. It 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 previously an obstacle to commercializing robot delivery service. The service robot can enter the apartment complex, access the 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 attracting significant attention from the logistics and retail industries. The Group expects last-mile delivery robots to increase the entire delivery process’s efficiency greatly.
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.
