History
Hitachi designed EMIEW3 with the goal of creating "human symbiotic robots that can safely co-exist with humans, providing robot-based services with advanced communication capabilities." EMIEW3 looks almost identical to its predecessor model, EMIEW2, but there are some significant differences: While EMIEW2 had single wheels for feet, EMIEW3 uses a wheel plus a smaller caster on each foot, a design that appears to make balancing easier for the robot while moving or standing still.
