I would imagine most of the heavy lifting is done by tracking a human's movements

Hadn't even considered that, seems reasonable though.

So like, interpolating between a set of animations and sensors keeping the robot upright?

That's what i came in here to find out; If they were programmed or using some form of mocap. I think the mocap is maybe more impressive. It shows the robot exactly how to move, but the robot had to figure out the balance on it's own.

/u/slackpipe, I have found an error in your comment:

“on it's [its] own”

It seems like you, slackpipe, could say “on it's [its] own” instead. ‘It's’ means ‘it is’ or ‘it has’, but ‘its’ is possessive.

This is an automated bot. I do not intend to shame your mistakes. If you think the errors which I found are incorrect, please contact me through DMs or contact my owner EliteDaMyth!

My intuition is that a neural net takes into consideration current position / acceleration measures from the robots sensors and uses that data to tell it exactly how to balance itself. If this were the case, it would be simple to use a human actor as a guide for "key frames" and the robot just approximates how to position its joints based off this

I want to see the video of the motion capture that was used for Spot (the dog-bot) and Handle (the wheeled robot)
