We'll spare you the excruciating detail: KHR-1HV + hip-swivel = good times. Whereas KHR-1HV's predecessors, the KHR-1 and KHR-2HV had plenty of robo-kit goodness going for them, the KHR-1HV really takes things to a whole new level, allowing for a much closer approximation to human walk, specifically that whole "turning" thing us Homo sapiens are so fond of. You'll also be glad to know that the KHR-1HV has a beefier battery, for extended circular jaunts, and the kit assembly is hardly complicated by the fancy new hip servos. The shoulder servos have been beefed up as well, allowing for a 270 degree range of motion compared to the former 180 degrees, but the new motors combined with that new battery pack do make the bot a bit top-heavy. Still, the 1HV is all-in-all a pretty good upgrade to the Kondo lineup, and while current owners of the KHR-1 or 2HV don't necessarily need to drop everything right now and buy one, we know they'll be jealous all the same.
