It's been a few years since we checked in on Navirobo. The iXs developed bot is now fully grown and fettered to Fujitsu and Kawasaki on a Japanese press tour. The bot features an impressive bag of tricks including an accelerometer ("ooo, it's bumpy"), light sensor ("don't forget to turn on the lights"), and voice guided navigation with the ability to point the way and describe nearby points of interest (read: honey pots). It'll even detect alcohol on your breath and presumably take a swipe at your jugular in just retribution. See for yourself in the videos over at Impress or check the few posted after the break.
