Everything in the video is generated, no canned animations. Its signal-based with oscillators, and other type of controllers.
In these videos you can see how far we got with walkers:
Horse-like:
spider-like:
biped-like:
We haven't been able to get walkers to be as efficient as other types of machines, and they didn't look cool. Thats why they didnt make the video.
"`I wonder what makes us build inefficiently-shaped human robots instead of nice streamlined machines?'
`Pride, sir,' said the robot."
Terry Pratchett (The Dark Side of the Sun)
But these segway-like things work surprisingly well, staying up with PID controllers:
So we haven't invented anything here. But we are proud of the single most important contribution we are making... which is to make accessible and fun, all these complex constructs.
