EMIEW 2: A roller-skater robot from Hitachi

Japanese company Hitachi which specializes in electronics, has created a robot that can roller blade. The little EMIEW2 humanoid robot has small wheels and shock absorbers which allow it to roll on surfaces that are not perfectly smooth. It's 80 cm tall and weighs 14 kg. Its maximum speed is 6 km/h. It has 14 microphones which can recognize human voices even when there's background noise. The purpose of EMIEW2 would be to act as a security guard (patroller), a museum guide or as a welcoming host (reception). http://www.youtube.com/watch?v=CCl7GRa7W3o
