Hitachi EMIEW goes about on wheels

The Hitachi EMIEW (Excellent Mobility and Interactive Existence as Work-mate) moves about on its wheels, relying on technology that can be found in the Segway as well. This allows it to zip about robustly compared to bipedal robots, hitting a maximum speed of 3.7mph with a reaction time of 100 miliseconds. The EMIEW has been usurped by its newer sibling, the EMIEW 2 which brings better technology to the table.
