Japan is so obsessed with the cosmetics/optics of their robots, or even quasi-robotlike vehicles, that I question if they'll ever produce anything functional.
Meanwhile, Boston Dynamics etc. seems to be going full tilt on not giving a damn of what it looks like, and going for bots like LS3 which can autonomously navigate rough wooded terrain it's never been on before, following a human operator, but picking it's own path, or the Atlas bot, wich most of the top teams in the DARPA challenge used, simply focusing on the programming.
And a shout-out to the South Korean HUBO which actually had the most points and the best time, the way the bot would kneel, then drive around on wheels whenever it didn't need to actively walk was genius.
