What even is a "take" anymore? My guess is they've been trying out the dancing thing for weeks, and recording it on their phones, and this just happened to be a good clip so they bunged it over to the PR department for dissemination.

A "take" would be get everything set up, start the robots' programs plus the camera(s), and hope nothing goes wrong before you get the footage. Phone recordings? Maybe, but I think they're using steadicams.

jrhowell · 30th December 2020, 03:26 PM

The first two thirds seems to be a single take, but later on there are a lot of cuts where the light coming in through the windows changes showing that it wasn’t done all at once. Still very impressive!

Haters gonna hate. This is a whole new field of applied engineering. How many billions in today's dollars do you think were spent getting heavier-than-air flight off the ground? There were literally decades of nothing, before it all came together for the first time.

Rudimentary motion in machinery induced by specific soundwaves is nothing new. Obviously they just took that same principle and expanded on it. To suggest that this is something that requires some sort of AI is silly.

To be fair and to back off, a little, from my original response - where are you seeing the suggestion that what we've watched "requires some sort of AI"?

Mike! · 30th December 2020, 04:16 PM

Was there more than one humanoid robot or did they do some kind of old fashioned 60's sitcom video magic to make the two dance together?

These things are AI wonders.

With a remote control car, you just press forward, and the wheels move the car forward.

When you tell one of these things to move forward, it figures out how to do that.

That simple looking dance move where Spot's legs are crossed requires a mountain of computation, and AI is part of that.

I'm pretty sure Boston Dynamic's robots move according to some elegantly simple algorithms for maintaining hysteresis in an unstable system, not mountains of AI computation. Maybe mountains of AI computation went into developing the algorithms?

In fact I think one of their earliest learnings was that it was actually easier to make an unstable robot that constantly shifted its footing to keep from falling over, than it was to make a robot that could just stand still like humans do.

That brings up the question, how much autonomy did the robots have doing the dance? Were they listening to the music and acting on it? Or were humans listening to the music themselves and then telling the robots to move in certain ways?

Replace the robots with humans, and what do you do?

Someone choreographed the dance routine. The camera is probably on a mobile robot too.

Now teach the robots the dance routine.

Like the humans, these robots aren't told when to move what muscle and by how much. They are told what kind of maneuver to do (a leg lift), and their software works out the best way to do that in their environment.

I suspect if a 50 gallon barrel rolled through the dance floor, the robots would sense it, avoid it, and get back to dancing. Based on all Boston Dynamic other videos.

That's pretty much how human beings do it. Totally unstable while walking, just keep moving. Standing still is pretty much harder for a human; and still extremely dynamic.

Why do you assume the robots were dancing to the music? What if they were just moving while music was playing?

Well, I've seen plenty of Boston Dynamic videos of them pushing robots around with hockey sticks. Apparently that's a big no-no now.

Adam Savage got one of their Spot robots and that video I linked does a pretty good job at explaining some of its basic autonomy.

crackers · 30th December 2020, 08:18 PM

Well, however they do it, it’s pretty darn amazing.

Watch the video. They are moving in response to the music. The only question is how much direction from humans have they had?

Robin · 31st December 2020, 05:24 AM

If someone had brought a set of Boston Dynamic videos back in time to 1968 and said that this is where robotics will be in the second decade of the 21st century, then we would have all been very disappointed.

Amazing video, in particular when you consider how difficult it is for some humans to learn to dance. For instance, when dance instructors say, "forward, back, forward, back," when demonstrating basic steps, they say "forward" when they are already making the step forward, but many people don't understand this simple principle and consider "forward" to be a command and therefore start moving forwards when the instructor is already taking the step back.

I don't think the robots are listening and acting on it. Robots would have been more precise when following the rhythm and keeping the beat, I think. So I think engineers were listening and making the moves after having programmed the robots to emulate them. In Copenhagen, we have quite a lot of engineers learning salsa dancing. When salsa dancers talk about somebody "dancing salsa like an engineer," it isn't usually meant as praise ...

How can you tell that’s what is happening rather than, for instance, the music has been put on afterwards to match the video?

In theory, they could have told someone to play music to match the robot moves, but I doubt this happened. Much easier to do it the other way round. In any case, I think it is amazing to see the robots do all of these moves.

That would be cool, a robot that could recognize rythm patterns in music and coordinate its movements to match. It could randomly choose from a catalogue of moves and give the impression of dancing.

I think that is within our capabilities but not what is happening here. This looks like robots performing programmed movements that change in time with a popular song.

Segnosaur · 4th January 2021, 12:56 AM

I for one welcome our new dancing robotic overlords.

rdaneel · 4th January 2021, 01:02 AM

We all better start practicing, looks like the robot apocalypse is going to be a dance off.

erlando · 4th January 2021, 01:16 AM

Does anyone really think this is robots autonomously listening and interpreting music on the fly and dancing?

Yeah, just no. Watch closely towards the end and observe the light coming in through the windows at different angles. This is quite clearly multiple takes implying that the music was synced in post.

The tech is impressive. But the robots aren't dancing.

Ziggurat · 4th January 2021, 02:07 AM

The robots are definitely dancing. It is undoubtedly a pre-determined routine, as are many human dances. What they probably are not doing is using external audio as a cue for the timing. But then, why would they? Robots can keep time perfectly internally. Humans aren't very good at that, that's part of why we mostly dance to the music.

I think doing that is amazing. Programming every move, in all three robots. That is a lot of work.

I don't believe they are using audio at all.

Indeed it is. Not as much work as doing what you originally suggested, that the robots were moving in response to the music.

Ni-en-leh pointed out that a philosopher might get into trouble by claiming that two times two makes five, but he does not risk much by claiming that two times two makes shoe polish." B. Brecht "The abolition of religion as the illusory happiness of the people is required for their real happiness. The demand to give up the illusion about its condition is the demand to give up a condition which needs illusions." K. Marx Last edited by dann; 3rd January 2021 at 04:54 PM.

The only question is how much direction from humans have they had? How can you tell that’s what is happening rather than, for instance, the music has been put on afterwards to match the video?

In theory, they could have told someone to play music to match the robot moves, but I doubt this happened. Much easier to do it the other way round. In any case, I think it is amazing to see the robots do all of these moves.

The only question is how much direction from humans have they had? That would be cool, a robot that could recognize rythm patterns in music and coordinate its movements to match. It could randomly choose from a catalogue of moves and give the impression of dancing. I think that is within our capabilities but not what is happening here. This looks like robots performing programmed movements that change in time with a popular song.

Watch closely towards the end and observe the light coming in through the windows at different angles. This is quite clearly multiple takes implying that the music was synced in post. The tech is impressive. But the robots aren't dancing.

It is undoubtedly a pre-determined routine, as are many human dances. What they probably are not doing is using external audio as a cue for the timing. But then, why would they? Robots can keep time perfectly internally. Humans aren't very good at that, that's part of why we mostly dance to the music.
