Technical Specifications & Social Implementation
Intuitive Voice Interface
Users can search for information on shops and facilities via voice dialogue and set them as destinations. The AI also provides real-time audio descriptions of surrounding landmarks and pedestrian activity.

Precision Sensing & Localization

LiDAR (Light Detection and Ranging): Uses lasers to accurately measure distances to walls and obstacles, capturing the overall geometry of the environment. By cross-referencing real-time data with pre-mapped layouts, the robot achieves precise self-localization.

RGB-D (Depth) Cameras: A system of three depth-sensing cameras paired with human-recognition AI allows for a wide-angle view, tracking the position and movement of pedestrians with high accuracy.

RTK-GNSS: To ensure absolute positioning, the unit utilizes an integrated satellite antenna combined with ground-based reference station data (Real-Time Kinematic Global Navigation Satellite System).

High-Performance Processing
All sensor data is processed by an onboard computer equipped with a high-speed GPU (Graphics Processing Unit), enabling the rapid recognition and decision-making required for safe, autonomous navigation.

Social Implementation & Proven Results
Dedicated to real-world integration, the project has undergone extensive pilot testing. Notably, the AI Suitcase operated throughout the entire duration of Expo 2025 Osaka, Kansai (April to October), with over 4,800 participants experiencing the technology. It is also available for demonstrations at Miraikan (The National Museum of Emerging Science and Innovation), a consortium member.

We continue to push the boundaries of development to realize a future where everyone can move freely and independently.
