Similar to all other 6-axis robots, SquidCuber solves a cube with slight modifications (in this case a small Lego plate glued onto each center). However, recently I have also made Cuboth, a super fast Lego robot that solves a cube without any such modifications: th-cam.com/video/Kjb-MmwueEQ/w-d-xo.html and it is in fact currently the world's fastest robot to do so (even counting non-Lego machines)!
Thank you! Yes, the idea of this project (as well as my previous robots) was to see how far Lego can pushed. While you of course cannot compete with the most recent overall record holders that use top of the line professional industry motors (which are orders of magnitude more powerful than the Lego ones), I am myself still a bit surprised how far one can actually get with "toy" hardware just by meticulous optimization.
@@bigsmall246 yeah Lego really makes the mark there as opposed to other ripoffs who don't go for the same amount of durability with individual bricks so major shout-out to Lego for doing that mad making our childhood infinitely better
@@EliasFrantar At first I was like "sub1 did that like years ago wdym fastest Rubik's Cube solving robot" And then I read the title again That's awesome
Thanks! Yes, the video is getting a lot of views recently (and views are also slowly but steadily increasing on my newest robot). I am very happy that so many people are now (after almost a year) watching my projects that I have put so much time into :)
Thank you! I am also a bit surprised that I managed to make it that fast, I just never stopped optimizing, always tried out new tricks and eventually (over the course of 3 robot iterations) reached the time you see in this video. If you had asked me a year ago I would have probably told you that a 1 second average with Lego is essentially impossible (at that time the best Lego solver was sitting at 2.2 average and already looked pretty much like the limit), yet here we are. :)
I've seen real robots do better, but I can understand why I shouldn't compare. This is a fantastic machine! I'm a LEGO fan and a cuber myself and amazed to see these both working together! Hope you can do more in the future!
My 8 year old learned to follow a technique to solve it. He is pretty quick now just from memory. He is developing his own variations I'm sure. This will blow his mind
I’ll never understand how you did it,but it’s so cool!!

Would it be possible to make a 4x4 solver with legos, I know middle layers will be pain but you can be the first one, maybe you can make fast popping sticks that can turn these.
A (fast) Lego 4x4x4 solver is actually my next project, which is planned for this year :) The 6-axis mechanism of SquidCuber is going to be very difficult to adapt for handling a 4x4x4 cube. I think extending the mechanism used by my newest robot Cuboth (that solves 3x3x3 cubes without any center modifications) is a lot more promising, but you will have to stay tuned to see what exactly I am planning! ;)
Question: does the fact that every starting scenario has the correct color in the middle of the face influence the difficulty of the solving algorithm?
Not at all. The solving algorithm does not use the colors red, blue, green, etc. but only treats them as right, left, up, and so on. This means, whatever color the center on the right face is, it will always be called R. Note also that the 6 centers of a cube can never move (you can check this on your own cube), which is why this 6 axis design actually works in the first place.
Hi Elias, I am from Science Centre Singapore and I would like to reach out to you with regards to SquidCuber. We are developing an exhibition on Robotics and while we were researching on what to showcase, we came across this video and would really love to showcase your SquidCuber. Is there any way we can discuss further?
From an engineering standpoint, friction and inertia would be the most difficult obstacles to overcome. I do see that the cube is modified for this reason.
It uses "rob-twophase" github.com/efrantar/rob-twophase, which is my own extremely efficient implementation of Herbert Kociemba's two-phase algorithm further adapted to take the robot mechanics (i.e. turns on opposite faces can be performed in parallel, a 180 degree turn takes about twice as long as a 90 degree one) directly into account while searching for a solution. This gives about 20% faster to execute solutions on average. Additionally, my solver returns more than 1 solution so that I can then also select the fastest one based on data about the timing of turn transition that I collected from prior solves. This solving algorithm is one of the keys to the exceptional performance of the robot.
That's a good question. The reason they are misaligned at the end of some solves is due to a combination of gear slack and Lego motors not being perfectly accurate. I am using a decent quality speed-cube here that allows smooth turning even when the layers are not perfectly aligned (this is usually called "corner cutting"). In fact, this is actually heavily abused by the robot (i.e. it deliberately starts the next move before the previous one is fully finished) and is one of the reasons why this machine is so fast despite using rather slow Lego motors.
Если по программе кубик был разобран, то по обратному алгоритму его всегда собрать можно. Надо его в ручную разобрать, и затем собрать на станке. Вот тогда будет интересно!

.....took the algorithm where you can rotate 2 opposite sides at once. This saves a lot of (waiting) time.
The fact is it was reverse video😁😁😁
This is amazing, props to the creator of this machine.

Dude, amazing work! I didn't know this was possible!
IT s possible If You put in reverse

How beautiful mathmatical calculation used

Nice job bro! Its great!

Wooowww man made my day. Machine learning , AI and automation damm great,time saving,productive and creative🎯🥳🥳

Why this incredible video is recommended to me now... Though I am using TH-cam from past 3 years.
Extremely impressive solution for extremely impressive puzzle toy.
It went so fast that slow motion looks like normal turning

If the robot does the mixing, than this is not a big deal. Just reverse the pattern. But if already mixed cube is inserted, than I am trully amazed.
THIS IS SO AMAZING
Wtf . Created it with legos imagine the amount of engeneering and time it took
Our future overlords...Legos...and they will create an army of Lego Terminators to quash the rebellion.
This is excellent.
Why are layers misaligned at the end? If it ever got misaligned while solving the pieces would fly out of the cube, so this obviously doesn't happen.

do you have instructions? i might want to make one myself
one second.........is more than enough
Robots will soon take over the WCA
OMG! ITS AMAZING!!! BRAVO 👏🏻
Can't believe Lego did this.
When you feel like 1 second of that is a minute
When SkyNet reaches awareness, this is how fast it will kill humanity lol
i feel like this machine is easier to build than solving a rubik's cube yourself
Nah
lol no
yeah i know...
Incredible
Props to this guy he did all of this with legos
