Hitachi has released a worker robot known as EMIEW 2 (Excellent Mobility and Interactive Existence as Workmate), an improvement over its predecessor that was developed way back in March 2005. This robot is capable of responding to spoken commands, travel along its two wheels at a top speed of 4 mph, and safely navigate its way through crowds of humans without bumping into them every few seconds. EMIEW 2 stands proud at 80cm tall and weighs 13kg, making it easy to carry around. A pair of Transformer-style legs have been included to allow the EMIEW 2 crouch on its knees, while an extra set of wheels has been included for greater stability.
