Robot solves Rubik's Cube in One Second*

* In less than 1.2 seconds. 1 second, if you round down.

Engineers Flatland and Rose are in the process of applying for an official world record for the fastest Rubik's cube solving robot, or indeed the fastest solver of any kind. Their robot can solve any scrambled state of the cube in <=1.2s, often much faster.
Their key optimization is to attach the stepper motors that do the turning directly to the cube by drilling holes in the cube's sides.

I welcome our new cube-solving overlords. Do you?

Very cool, but for competitive purposes I think the holes are cheating. Of course I don't make the rules, but I would think that such a machine should be expected to solve any standard rubics cube presented to it.

If you get a brand new rubics cube out of the packet there's no way a person could solve it in 5 seconds or whatever the world record is. The cubes used for speed solving are worn in, may have different tension springs in them and will certainly be lubed.

If human cubers can modify the basic cube then it seems fair that the robot cubers can too. I'm not sure there's anything in the actual rules that would prohibit a cube as in the video.

The humans also get a period of time to look at the cube and figure out the moves they need to do before starting. The robots don't get that. At the end of the video the robot figures out the moves and solves the cube in less than 1.1 seconds, without seeing it before hand.

Somewhere in the world, someone is wondering what it's like to put their penis in this thing. In fact, i was the first to say it so in horror i realise i might be that person.
