Until yesterday, the world record for fastest time in solving a Rubik's Cube was 5.27 seconds, which was set in the fall of 2011 by a Lego robot named Cubestormer 2. Thanks to the machine's successor (aptly named Cubestormer 3), the time to beat is now 3.253 seconds. The robot, which is the third in a series of automatons designed solely for the purpose of solving the Rubik's Cube ASAP, is powered by an octa-core Samsung Galaxy S4; it's got four high-performance ARM Cortex-A15 cores and four lower-intensity Cortex-A7 cores running the show, each one managing its own Lego Mindstorms actuator.

Very interesting. Now that he broke a Guinness World Record, should machines even be allowed to break world records?

A lot of it has to do with the mechanical Lego actuators...

Yes, but a differenciation should be made, same as other speed records.

Exactly. Take the mechanics out of the equation and a smartphone can do the calculation in a split second.

This robot solves it 6 times faster than I do xD
Warning: Spoiler! (Click to show)
WR is 5.55 seconds done by Mats Valk
https://www.youtube.com/watch?v=vhTMm85G9GE

I wonder if this robot didn't do a DNF (did not finish) because of the inspection time (15 sec)

Back on topic:
I'd say no because to break a record we have to train very hard. With the machines, you just have to build it the right way. (It also takes a long time but less training)

I don't see why it can't be record breaking. The machine didn't build itself, it took knowledge and engineering to create it. Humans are the basis of all records and this had lots of human element to get it that fast.

True.
But basically solving it is a simple process with a few ground rules. Faster solving by humans is basically being able to be faster at assessing the situation and which move to do next.
The only "downtime" of doing it mechanically, is not the understanding as that is way too quickly done, but the actually moving the cube.
If it was fully digital, a simple home computer could solve it way under a minute. Even milliseconds if it has a quick single core performance.

So even if this is a nice achievement, its not an "omg this is amazing!" one.
I'm pretty sure that by the time the motors were half way there, the phone had already finished solving it and just waited for the motors to complete the steps.

I see your point of view. I wasn't open-minded enough..
But as heinz357 said, tehre should be two categories. One done by a human and a second done by the machines. I agree that there will always be someone behind a record.. It could be him/her that break the record or his/her machine, as it itsn't the same way to achieve it.

Humans have trillions of non-human-per-se cells working in equilibrium.
Maybe credit should be given to those too for "human" records, much like all our conscious ancestors, as no human builds him/herself either, unless we find a guy or gal left in the jungle or a inhabited island ala "Greystoke" (and he/she most likely would not be very good at solving Rubik cubes).

We are merely parts of the chain of life, not individuals (really).

Lego robots that solve Rubik cubes are a small part of our technological evolution. Important in itself, tells a lot about the bigger picture, means nothing really if it is removed completely from our repertoire in itself. Much like we humans, we are the pinnacle of mammalian evolution on Earth thus-far, but should we all drop dead, life would not hesitate for a second to keep going, and probably surpassing us.
