Nippon Telegraph and Telephone: NTT Group companies begin demonstration experiment in autonomous and efficient food delivery using robotsCreating valuable new experiences for office workers and sales opportunities for restaurants

Tokyo – October 3, 2022 – NTT Urban Solutions, Inc. (Headquarters: Chiyoda-ku, Tokyo, Representative Member of the Chairman of the Board: Hiroshi Tsujigami), NTT Urban Development (Headquarters: Chiyoda-ku, Tokyo, President and CEO: Hiroshi Tsujigami), NTT Communications Corporation (Headquarters: Chiyoda-ku, Tokyo, President and Chief Executive Officer: Toru Maruoka, “NTT Com”) and NTT Corporation (Headquarters: Chioyda-ku, Tokyo, President and Chief Executive management: Akira Shimada, “NTT”) are working together to reduce the need for human labor by using robots in a new initiative. The four companies are running demonstration experiments involving food delivery using autonomous robots linked to mobile ordering apps. Through this demonstration, they also aim to create new and valuable experiences for office workers and sales opportunities for restaurants. This demonstration will begin on October 3, 2022 at the Urbannet Nagoya Nexta Building (1-chome, Higashi-sakura, Higashi-ku, Nagoya), a new construction completed in January 2022.

Overview of the demo experience

Seamless coordination between robots and buildings is becoming commonplace. By collecting information about building facilities, routing and storing traffic information and other data in the cloud, the robot autonomously searches for the optimal route without human instructions after receiving a command, all to be picked up and delivered to the relevant floor.

Verification details
Verification of user needs (users and restaurants)

User needs

• Food and drinks delivered in a reasonable time
(within 5 minutes before or after the scheduled delivery time)
• Be able to receive unlimited food and drink

Restaurant needs

• The operation for the delivery of the robot is not an obstacle to the management of the store
• Helps increase sales opportunities

Technology Verification

Optimal route identification

• Appropriate delivery can be determined automatically using technology that captures and predicts the external environment, such as traffic on the delivery route and elevator usage, etc., by calculating the optimal route.

Optimization of delivery routes

• Multiple orders can be efficiently delivered in the shortest time and with the fewest operations using multiple robots.

Robot control optimization system

• Combine the two technologies above to schedule and deliver the optimal operation, delivering appropriately at the time requested by the user.

We will use NTT’s “Machizukuri DTC”®1 and “4D digital platform®2 technologies to carry out this demonstration. In addition, we will use 5G for communication with the robot, which is characterized by high speed, large capacity and low latency. 5G communication will achieve safe and secure indoor delivery services by determining the position information of the robot, providing camera images on the road and the working status of multiple units.

Role of each employee:

NTT Urban Solutions

• Scheduling the robot usage service
• Use case study and verification

NTT Urban Development

• Various adjustments and maintenance of the environment (for the provision of demonstration services in the field of demonstration)


• Development of the 5G/LTE communication environment
• Various bot considerations and adjustments for system implementation


• Development of predictive optimization technology and algorithms including “MachiZukuri DTC®” in collaboration with NTT Smart Data Science Center

Upcoming developments

Initiatives to use robots

NTT Urban Solutions is already using robots for security and cleaning at Urbannet Nagoya Nexta Building. Going forward, we will continue to work for increased use of robots in buildings and neighborhoods in anticipation of a declining workforce, such as robot delivery in neighborhoods (including indoors and outdoors). ‘outdoor), integrated control (including robots for different purposes), and multi-use of robots. We will continue to investigate and verify surrounding issues.

NTT Group’s vision for urban development

NTT Group aims to create new value by integrating various robots into everyone’s life through the “MachiZukuri DTC®” using the IOWN concept3 Technology.
The robots will not only perform delivery, security and cleaning functions, but will also predict and anticipate each person’s current status to provide comfort, safety, convenience and excitement.

1“Machi Zukuri DTC®” is a technology that optimizes the whole city by linking various functions such as store management, food loss prevention and human service (hospitality) based on the concept of digital twin computing4. Please see the Related Press Releases section below to see other related initiatives.

3The “IOWN Concept” uses innovative technology to overcome the limitations of conventional infrastructure, optimize individual and entire systems based on various types of information, and create a thriving society open to diversity. It is a network and information processing infrastructure comprising terminals capable of providing high-speed, high-capacity communication and innovative technologies centered on this concept.
At the NTT R&D Forum: Road to IOWN 2022*, which will be held from November 16 to 18, 2022, we will demonstrate a robot-based food delivery operation demonstration.
