EMIEW
EMIEW is a compact wheeled social robot designed for human interaction in indoor environments like offices, airports, and retail stores. It serves as a workmate for tasks such as visitor reception, guidance, surveillance patrol, and customer greeting, moving at human walking speeds while avoiding obstacles. Key features include agile two-wheel self-balancing mobility, collision avoidance via sensors, natural voice recognition with 360-degree sound detection using microphone arrays, facial recognition, high-quality speech synthesis in multiple languages (Japanese, English, Chinese, Korean), and expressive arms for gesturing. It supports cloud-based processing for advanced voice/image recognition and can interact naturally without a microphone at 1m distance. Use cases involve assisting lost tourists to facilities, office worker support, and retail customer engagement, emphasizing safe symbiosis with people.

Q2. What are the main capabilities and key features of EMIEW?
EMIEW robots feature multilingual voice recognition, autonomous navigation with obstacle avoidance, and cloud-based AI processing. Models incorporate sensors for environmental awareness and four-wheel locomotion for stable movement in facilities.
Q3. Who is EMIEW built for, and which industries can benefit from it?
EMIEW targets operators in offices, hospitals, care facilities, airports, train stations, and retail stores. According to Hitachi, it supports visitor reception, guidance, and surveillance in building environments.
Q4. Is EMIEW a commercial product or still a research prototype?
EMIEW transitioned from research prototypes to commercial offerings, with models like EMIEW4 entering full-scale operations in Japan as of 2020. Earlier versions such as EMIEW3 were demonstrated in service applications.
Q5. Is EMIEW currently available for purchase, and when is it expected to ship?
As of 2026, EMIEW models are available through domestic sales in Japan, primarily via individual quotations. Shipping occurs approximately four months after order receipt, according to manufacturer announcements.
Q6. How does EMIEW actually work in real-world environments?
EMIEW operates via sensor fusion from cameras, microphones, LiDAR, and gyroscopes for voice interaction, obstacle avoidance, and path planning. It connects to cloud platforms for AI-driven responses in dynamic public settings.
Q7. When was EMIEW announced or officially launched?
The original EMIEW was developed and announced by Hitachi around 2005, with EMIEW3 launched in 2016 and EMIEW4 entering commercial operations in Japan in 2020.
Q8. How is EMIEW different from other robots in the same category?
EMIEW distinguishes itself with four-wheel locomotion including casters for balance, self-righting after falls, and integration with building systems like surveillance cameras. According to Hitachi, it emphasizes human symbiotic operation over bipedal designs.
Q9. Does EMIEW require additional development or customization after purchase?
EMIEW supports integration with external systems for tasks like coordination with surveillance. Hitachi positions it for deployment with manufacturer-provided software, though site-specific adaptations may be needed for optimal performance.
Q10. What is the future roadmap or planned upgrades for EMIEW?
Hitachi announced plans in 2020 to expand EMIEW deployments with models like EMIEW4 and desktop variants, targeting enhanced mobility, automated recharging, and broader language support for building services.
