What’s inside
The parts the company has talked about publicly.
- Movement
- Wheeled base · 23 joints
- Actuators & motors
- 21 DC motors; 23 DoF (head 3, arms 5 each, hands 1 each, legs 3 each, wheels 2). Each foot has a wheel plus a small caster.
- Hands
- Simple 1-DoF grippers, slightly redesigned from EMIEW2.
- Sensors & vision
- HD camera, laser range finder (LIDAR fitted through a cut-out in the neck), 14-channel microphone array; can also use network cameras installed in the building as extra eyes.
- Compute
- On-board computer for motion control and networking; an external 'remote brain' (cloud) handles navigation, voice, image and language processing.
- Battery & power
- Lithium-iron-phosphate battery; about 3 hours of operation.
- Materials & build
- Hard plastic and soft rubber exterior over a metal and plastic frame.
- AI & software
- Hitachi 'remote brain' robotics IT platform: one system monitors and controls several robots at different sites, shares information between them and can send recovery instructions after a failure. Speech recognition and translation that copes with street noise; predictive collision avoidance carried over from EMIEW2.
- Other details
- 90 cm tall, 15 kg, keeps pace with walkers at up to 6 km/h, crosses 15 mm floor steps and can stand back up after being knocked over (new in EMIEW3). Depends on network connectivity for its smarts.
