I remember when I was a kid they showed a cube solving robot on the news. They said it was impressive but still not as fast as the fastest human. Amazing how far we’ve come in 15 years or so.
@@ABD-hw5ff Actually... The processing speed of cpu's very quickly outdid the rest of the computer parts. It was a sort of arms race between the chip makers and they got burnt out pretty quick. Nowadays, the bottleneck isn't clock speed, but memory locality (how quickly data can be accessed). Next, the algorithms used are more efficient. This video explains the gist of it: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wL3uWO-KLUE.html Lastly, the ability to cache everything with gigabytes of memory really helps speed things up.
I'm interested to know if they had to think about the inertia from a spin making the next adjacent spin not possible so they switch to a different face of the cube while the inertia settled down, then going back to the adjacent faces. It's a minor detail but at this speed the developers have to think of everything!
A year late, but I've only just seen this video. If you watch the 0.03x replay, you can see that the faces overshoot at the end of a rotation, and the robot has to wait for it to come back into line. I reckon this is the inertia of the cube parts. If you look at the blog-link, you can see a plot from the optical encoders that record where the motor is ... and the motors themselves don't seem to have any appreciable overshoot, so I reckon the inertia is what's causing this. Without that, it could have solved even faster :)
hi styx rakash have you become a flat earther yet? If not I suggest watch a 13 part series called _What on earth happened_ by Ewaranon to learn that the earth is not a globe. I got it in my about tab. Also if you want to watch a flat versus globe debate I suggest watch a video on Modern-Day Debate called _FE DEBATE: Austin @WitsitGetsIt & @flatearthtests9708 Vs @MrSensible & @culturecatz_
The nerdiness of this clip and what it depicted is so intense that it constitutes a threat to the fundamental fabric of space-time in the Local Group of galaxies. I'm just not enough of a nerd to explain it further than that.
It looks like the machine even programs a delay after every turn so the cube itself can recover from the super fast turn, or else it might break if the machine doesn’t delay. That’s totally nuts!
I think two stage movement can increase speed a little bit more. Imagine it moves 45 degrees and the resulting overshoot puts the corner to correct position, then the rest 45 degrees follow. :D
@Sameer Samant big talk for someone who has broken english and currently can't understand a joke, and not that the world revolves around me but i didn't ask about your workout sessions, or also this video or comment has nothing to do with your workout stuff i can understand the non-existent so called manliness and increased testosterone that you are saying that you have, it's just that you don't understand such a simple joke that even a 10 year old can understand, in fact your name does not sound very France, it's more like indian. Please think before you say something. You could have thought of a better and maybe even more positive comment rather than trying to get on someone's nerves.
“Exactly, what IS a cube? Webster’s dictionary defines a cube as a 3-dimensional object with 6 faces and all equal sides....... ........and so the Romans created the Rubrics Cube to....... ..........this machine was designed by Dr......... ...........and so now we are going to solve the Rubriks Cube once and for all, but first don’t forget to Subscribe....... ............”
Would be nice to replicate an actual solve with a method instead of just FMC, the scramble in this video looked pretty alright with that free yellow pair.
Cubes generally only come apart if they’re turned when not properly aligned, so that is not a factor here. Having said that, the robot did not actually solve the cube, it merely reversed a sequence of moves it was programmed to make from a completed cube.
I love how they blacked out the orange tiles, as the rgb values for red and orange would look too similar in realistic lighting for the sensors to distinguish
Kevin Uibu can you imagine people loosing their jobs to this? I mean no more rubix cube challenges but now robots can work faster and better. This is more alarming than exciting. 😰
The most surprising thing I found about this is you can see their recoil every time they turn. It makes me think how many things happen but are too fast for me to realize.
I had to laugh because I imagined, "Here Dexter, solve this"...Dexter goes, "GUIVE", pushes his glasses up, picks up the cube, and his face goes red like he's straining to fart... then 2 seconds later, with one eye clamped shut and the other wide open looking at the bridge of his nose, his hands burst into a blur and he solves the cube in 20 moves in 0.38 seconds.
@@tariqnabi8118 No, this video is a real, confirmed world record - you can look it up. You can also tell it's real because: 1. The way the red light is flickering. It happens because the FPS of the camera is faster than the flicker speed of the light. 2. The faces keep overshooting *every time*. This is due to the super quick acceleration and deceleration. It would never happen when rotating them slowly.
