Murata Girl, aka Seiko-chan, with her twin sister at . She's just one of several robots being demonstrated here at the Japanese electronics show outside of Tokyo. Murata Girl can ride forward and backward at 2 inches per second--or idle in place. Tiny sensors tell the bot when it's about to bump into something, and gyroscopes on her back, plus a spinning disc embedded in her stomach, help her stay balanced.
She can be controlled via a Bluetooth wand (not pictured).
