Robot Brief

EMIEW3 (Excellent Mobility and Interactive Existence as Workmate) is a humanoid service robot developed by Hitachi, designed to assist people in public spaces such as airports, train stations, retail stores, and offices. Launched in 2016, EMIEW3 features a compact and lightweight design standing 90 cm tall and weighing 15 kg. It moves smoothly at human walking speed (up to 6 km/h) using a unique four-wheel locomotion system that includes wheels plus smaller casters on each foot for improved balance and maneuverability. The robot is equipped with advanced sensors including a 14-channel microphone array, HD cameras, laser range finders (LiDAR), gyroscopes, and environmental sensors, enabling it to recognize and respond to human voices in Japanese, English, and Chinese. EMIEW3 integrates with a cloud-based robotics IT platform (“remote brain”) for intelligent processing, allowing it to provide real-time customer service, guidance, and information. It can autonomously locate customers needing assistance, navigate complex indoor environments, avoid obstacles, and even right itself if it falls. EMIEW3 aims to enhance customer satisfaction and operational efficiency by providing reliable, multilingual interactive support in busy public venues.

Use Cases

EMIEW3 assists lost tourists, guides customers in retail environments, supports office workers, and provides information in public facilities. It recognizes and processes voice commands in multiple languages, navigates autonomously while avoiding obstacles, and interacts with people using a friendly child-like voice. The robot can respond to questions, provide directions, and share information about nearby facilities or products, contributing to improved customer experience and operational support.

Industries

  • Airports & Train Stations: Customer guidance and information services.
  • Retail: Assisting shoppers and providing product or store information.
  • Offices: Supporting employees with information and navigation.
  • Public Facilities: General visitor assistance and interactive engagement.

Intro

EMIEW3 is a compact humanoid robot standing 90 cm tall and weighing 15 kg. It uses a unique four-wheel locomotion system with wheels and smaller casters for stable and agile movement at speeds up to 6 km/h. The robot is equipped with HD cameras, a laser range finder, a 14-channel microphone array, and gyroscopes for environmental sensing and navigation. Its AI system connects to a cloud-based robotics IT platform that processes voice and image data, enabling advanced interaction and autonomous operation. EMIEW3 can recognize three languages (Japanese, English, Chinese), respond with a child-like voice, and autonomously navigate complex indoor spaces while avoiding obstacles. It can also recover by righting itself if it falls.

Connectivity

  • WiFi (IEEE 802.11a/g/n) for cloud connection and remote monitoring.
