A service robot that delivers information on the move
Collibot
Signage Model / Delivery Model
Collibot is available in two types: the Signage Model for guidance and information delivery, and the Delivery Model for meal delivery and transport.
Collibot is a service robot family featuring 2 purpose-specific types. The Signage Model delivers guidance, advertising, and information while moving through commercial facilities and hotels, while the Delivery Model transports food, tableware, and supplies in restaurants and facilities.
In-Store Customer Service Solutions Powered by Collibot
The signage model delivers in-facility displays and customer engagement while patrolling, whereas the delivery model handles transport. With either configuration, display switching and visitor data logging can be linked via the cloud.
- Signage Model: Displays promotional campaigns and facility guidance while navigating the floor
- Delivery Model: Reduces staff round trips through food delivery, table clearing, and supply transport
- Both Models: Swap tailored content by time of day or day of the week with no coding required
Key Features
Integration with business systems
Enterprise integration APIs allow either configuration to be incorporated into existing operational workflows.
Supports meal delivery and transport

Signage Model
Signage Model delivering guidance and information on the move
The 32-inch displays on both sides of the unit display facility guides, campaigns, menus, and more while on the move. In configurations combined with Kebbi, interactive dialogue and customer attraction can be layered onto the signage display. Display content and continuous operating time are confirmed based on configuration and operating conditions. Japan's digital signage market expanded to 274,000,000,000 yen in FY2024 (announced by Fuji Keizai in 2025). Stationary models deliver information where they are installed. In contrast, this model patrols the facility, bringing information directly to the flow of people.
No-code operations
Quickly update on-site tasks with Roflow
Even without programming experience, you can build workflows for guidance, speech, movement, and standby directly on the Roflow screen. The system is designed so that on-site staff can easily adapt to changes such as seasonal menus or in-facility events.
Delivery Model
Delivery model supporting food delivery, table clearing, and supply transport
Equipped with 3-tier trays, the delivery model handles the transport of food, tableware, and supplies in restaurants and hotels, reducing the round-trip workload for staff. Designed around trays with a 10 kg capacity per tier and approximately 10 hours of continuous operation, it is deployed after verifying aisle widths, flooring, and actual traffic flow.
Product Images (by Model)
The Collibot family consists of 2 types: the signage model for guidance and information delivery, and the delivery model for food serving and transport. Choose the right model for your application and on-site traffic flow.
Delivery Model
Configured with 3-tier trays to transport food, tableware, and supplies. Ideal for food delivery, dish return, and intra-facility transport.
Signage Model
Guidance and advertisements are displayed on the 32-inch displays on both sides of the unit, delivering information while moving. In addition to the commercial version's appearance, you can also see official videos, human-robot collaboration, and operations at PoC and deployment sites.

Frequently Asked Questions
Where can it be used?
It can be used on flat indoor floor surfaces in restaurants, hotels, commercial facilities, and similar settings. The delivery model is suited for serving food, bussing tables, and transporting items, while the signage model is suited for reception, guidance, and displaying advertisements. We check aisle widths and traffic flow prior to deployment.
Can it navigate while avoiding obstacles?
In addition to LiDAR SLAM, it travels while sensing its surroundings using a combination of ultrasonic, IR, ToF, and obstacle detection sensors.
What are the unit dimensions?
The delivery model is 500 × 513 × 1,164 mm, and the signage model is 500 × 513 × 1,223 mm. To ensure safe operation, we verify on-site traffic flow using a minimum aisle width of 850 mm as a guideline. Please refer to the specification table on the same page for detailed dimensions.

What is Roflow?
It is NUWA's cloud development tool that visually combines robot movement, speech, screen display, and more. Even without programming experience, you can configure service flows tailored to specific use cases.
Must it always be combined with Kebbi?
No. Both the delivery model and the signage model can be operated standalone. You can choose a configuration combined with Kebbi when you want to increase human interaction, such as attracting customers, presenting menus, or providing facility guidance.
Can it be made to speak specific lines?
Yes. You can configure the robot's lines within the corresponding service flow to match guidance content for your store or facility.
How is map setup performed?
Using map creation and management functions, you configure navigation areas, destinations, restricted areas, and more. During deployment, we verify the on-site environment and design safe traffic flow.
What tasks can be configured for restaurants?
With the delivery model, you can combine food delivery, table clearing, patrolling, and item transport. Tasks involving interaction and display—such as welcoming guests, introducing dishes, and facility guidance—are supported by the signage model or configurations paired with Kebbi. Available features in Japan vary depending on configuration and contract terms, so please consult us via the contact form.
Please tell me the process for implementation.
