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.
