Is that CFOP I see? ._.

Ooh cool.
Good idea having the turning mechanism physically attached to the centers.
I wonder if one of the reasons it's a little quicker than others is because when it does the scramble it knows what the position of the cube is, rather than having to take images of the different sides and determining the state.
Hmmm, I wonder if corner cutting could be incorporated into the turning to speed it up a little.

Ah, the move count is quite high for the solve isn't it. Also the scramble sizes are quite small (12 and 14 - that's a little low for a random state isn't it?)

YES

 

[ben1996123]

YES

O.K. THANK YOU.

Also, the scrambles should be either random state or more than 20 moves.

...why would you use cfop...

 

[qqwref]

probably because roux is slow when you don't have M slices

BURN


...but yeah, you should really use random-state scrambles and a better solving method. Unless the point is to demonstrate the limits of a CFOP solve, in which case go ahead, I guess.

duh, everyone knows cfop is the best method because the world record was set with it.

Thats kinda the machines fault, isnt it?

 

[qqwref]

Try it yourself - see if you can figure out a way to hold the cube totally steady, and do 10+ tps for any move sequence, while allowing all layers to potentially rotate. It's not easy... far easier to just hold the centers constant.

Damn

 

[Kirjava]

qqnoob -> you can do M2 with L2 R2

 

[ducttapecuber]

If you were to create such bot, why wouldn't you have the robot use ZB, becasue it would have instant reconition, and wouldn't its time be better?

 

[cubegenius]

I see no M or F.

 

[yejun]

There are five axeses only. No green, defined as D. With CFOP, D is not needed.
I'm looking for a better means than CFOP. But there should be no D and no M. M can be replaced LR' but M might create D, even there is no D.
Who can help me?

 

[Kirjava]

You should be using Kociemba, but since you might have to use D, 1LLL is probably your best bet.

dafuq. cube turning sounds crappy

1. scrambles are random state AND more than 20 moves
2. taking image is really slow due to low performance of camera. It's can be much quicker by other solution.
