You may not be able to build an HRP-4C
fembot in your average garage, but the programming would practically take care of itself -- not only does the AIST humanoid sing
using off-the-shelf Yamaha Vocaloid software, its dance moves
are click-and-drag, too. Roboticist Dr. Kazuhito Yokoi gave IEEE Spectrum
an inside look at the HRP-4C's motion trajectory software, which works much like 3D animation tools: you position the limbs where you want them to start and when you want them to end up using keyframes
, and the software takes care of the rest. The system's intelligent enough to generate a 6.7 second sequence from just eight keyframes, and it compensates for hazardous instructions, too -- if your haphazard choreography would tip her over or send limbs flying, it'll automatically adjust her moves.
