At the Robo Japan 2008 Convention, Takara Tomy's old i-Sobot was supplanted as the smallest, two-legged humanoid robot. While the i-Sobot is already diminutive at only 16.5cm in height, Tomy's new Robo-Q looks positively minute standing next to its older sibling (see picture for reference).

Robo-Q is only 3.4cm high and can navigate mazes and play games. it was created in the aim of creating a micro-pet so features like infrared sensors are to be expected if it's to move around autonomously and avoid bumping into objects. It could also be navigated via remote control to kick equally minute balls around, for example. Takara Tomy's Robo-Q will be available in Japan in four color schemes starting February, 2009 for a little less than $40.
