Press release

Robot for unmanned viewing

-A new form of communication between customers in the New Normal era and housing sales-

Our one-story model house "Hiraya ga Millerun" supports unmanned viewing

We have introduced a remote-controlled robot (mascot name "Millerun").



Background of introduction


It is thought that there are requests for a leisurely tour with the family alone, and for avoiding the risk of face-to-face contact in the New Normal era after the new Corona. In the existing video customer service system, the person in charge communicates through the screen to answer customer's questions and guide the specifications and equipment, but the location was limited to a few places in the building where communication is possible. Was the current situation. Therefore, taking advantage of the one-story building without stairs, we started to consider the introduction of a remote-controlled robot that can move in the indoor space together with the customer and talk while looking and moving together, and started full-scale introduction in May 2021.


Expected effects of introducing a remote-controlled robot
1. Communication where you can feel contact while not contacting
2. Product description while moving indoors and looking at the actual item
3. Confirmation of places of interest for visitors

The moving robot customer service expands the range of guidance that can be provided while being unmanned, and the information that can be input becomes closer to that of manned customer service. In addition, the operator who remotely controls the robot guides the customer by becoming a robot with a unique shape that makes them feel familiar. This makes it possible for customers to obtain information about housing while slowly inspecting at their own pace and casually communicating through robots without feeling the tension felt by a real sales representative. I will.


IoT offerings to let you enjoy smart home life


Life will be more flexible with the little help by technologies.

Casa robotics’ one-story houses are equipped with IoT devices to lets you spend a smart home life.

Key Smart Home Features

Smart locks

Because IKI’s next-generation smart locks are able to issue different passcodes to each person, they can identify who is entering the house. They let parents at work know when a child comes home, let guests use your house when you are away from home for a couple of days, etc. Smart locks give you a sense of security at a higher level.

Smart lights

IKI houses come with a multi-functional smart light, which can control intelligently an air conditioner based on its internal thermometer, monitoring activity levels of family members with its motion sensor and lets you enjoy a shower of sounds coming from the ceiling which is made by the built-in speaker. Smart lights let you feel safer and more comfortable.


Next-generation VR and Zero-contact House Tours

IKI model houses minimize contact between customers and sales representatives. It is made possible by two key technologies.
Next-generation VR

The next-generation VR, which is much more realistic than conventional VR (Virtual Reality), allows you to self-view actual model houses and architectural examples.
With next-generation VR, you can also measure the floor plan dimensions in the VR space, so you can check in advance whether your furniture will fit. The screen is an image.

Zero-contact House Tour System

Experience the IKI space to the fullest in a model house without a sales representative. This is made possible by a zero-contact house tour system that takes advantage of the characteristics of IKI as a smart home.

When you apply for a house tour via the app or web, you will receive a passcode for the smart lock at the entrance of the model house. The customer can enter the model house directly at the reserved time.

Inside the model house, we have prepared a spot where you can communicate remotely with the Casa robotics concierge. The concierge can answer a variety of questions about the house while avoiding a physical face-to-face encounter.
