Collaborative Development to Realize a Smart Robotics Building ConceptCreating Comfortable Spaces Based on Robot Technologies
Yaskawa Electric Corporation ("Yaskawa Electric"; head office: Kitakyushu, Fukuoka; president: Koji Toshima) and Shimizu Corporation ("Shimizu"; head office: Minato Ward, Tokyo; president: Yoichi Miyamoto) are currently working in partnership to develop the component technologies needed to realize a next-generation smart robotics building concept. The two companies have established "smart showrooms" to stage the first demonstrations of this collaborative effort.
The smart robotics building concept seeks to realize diverse services and comfortable spaces in a building by integrating building infrastructure technologies and robot technologies (RT). The goal is to achieve the harmonious coexistence of people and robots within buildings, where robots can play active roles in various settings, including reception and information desk service, delivery, cleaning, and security. For example, when a visitor enters the building, the closest robot can approach him/her and offer assistance, guide the visitor to his/her destination, give a guided tour of the building facilities, or provide other specific services.
Key points to creating a smart robotics building are efficient role-sharing and the establishment of cooperative systems between the building and the robots. Rather than having robots perform all functions, robot technologies must be combined with infrastructure technologies incorporated into the building itself, including information communications, human detection, and equipment-control functions. Centrally managing all building functions, including the IDs and positions of robots operating within the building, will make it possible for multiple robots to perform a wide range of functions and services. The building infrastructure also allows for easy incorporation of purpose-specific robots.

The smart robotics building concept
As the first demonstrations of the smart robotics building concept, spaces called "smart showrooms" have been established in buildings belonging to Shimizu and Yaskawa Electric. The smart showrooms are experimental spaces that incorporate Shimizu's infrastructure technologies and Yaskawa Electric's SmartGuide guidance robots. Verification tests performed at the showrooms have demonstrated the effectiveness of services rendered by robots in tandem with the building infrastructure.
In these smart showrooms, the SmartGuide robots interact with people—for example, by greeting guests, explaining items on display, and escorting guests from the building when they depart. Elements of the building infrastructure detect individuals entering the showroom. Based on information provided by the infrastructure, the SmartGuide robots provide spoken explanations of displayed items or give presentations using a projector, depending on the needs of each guest.

Overview of the SmartGuide guidance robot
Shimizu and Yaskawa Electric plan to continue joint development efforts, incorporating advanced technologies into various building operations and functions (including reception, delivery, and security) to realize the smart robotics building concept. In the near future, the companies plan to demonstrate and verify robot technologies for receiving and escorting guests (SmartEscort) and for delivering packages to offices (SmartDelivery).
