Watch: A robot just solved a Rubik’s cube in 0.38 seconds

The world record for humans, meanwhile, is 4.69 seconds.


The Guinness World Record for the fastest a human can solve a Rubik’s Cube is 4.69 seconds. The record for the fastest a robot could solve it, thus far, was 0.637 seconds. You wouldn’t think it’s possible, even for a robot, to beat that!

But a robot from MIT’s Biomimetic Robotics Lab has just (unofficially) broken the record by solving the Rubik’s cube in a mind-bending 0.38 seconds, as you can see in the video (above). Of course, now that the moves for solving the cube are known, speed is really matter of mechanical dexterity.

The robot in the video above was created by Ben Katz, a robotics student, and software developer Jared Di Carlo. At first, it looks like the puzzle was magically solved in one turn. However, the video slows down to show exactly how the robot solved the cube.

The duo who made the robot claimed in a blog post that the machine can actually go faster, except the tuning process was time consuming and often ended up in mistakes, like the “cubesplosion” in the video below. Citing that they have “lost interest in playing the tuning games” for now, the two said they may return to the robot eventually and attempt to solve the puzzle even faster.

Can a colour encourage creativity and innovation?

The story behind the universally favoured colour - blue.

It was sought after by many artists. It was searched for in the skies and deep oceans. It was the colour blue. Found rarely as a pigment in nature, it was once more precious than gold. It was only after the discovery of a semi-precious rock, lapis lazuli, that Egyptians could extract this rare pigment.

For centuries, lapis lazuli was the only source of Ultramarine, a colour whose name translated to ‘beyond the sea’. The challenges associated with importing the stone made it exclusive to the Egyptian kingdom. The colour became commonly available only after the invention of a synthetic alternative known as ‘French Ultramarine’.

It’s no surprise that this rare colour that inspired artists in the 1900s, is still regarded as the as the colour of innovation in the 21st century. The story of discovery and creation of blue symbolizes attaining the unattainable.

It took scientists decades of trying to create the elusive ‘Blue Rose’. And the fascination with blue didn’t end there. When Sir John Herschel, the famous scientist and astronomer, tried to create copies of his notes; he discovered ‘Cyanotype’ or ‘Blueprints’, an invention that revolutionized architecture. The story of how a rugged, indigo fabric called ‘Denim’ became the choice for workmen in newly formed America and then a fashion sensation, is known to all. In each of these instances of breakthrough and innovation, the colour blue has had a significant influence.

In 2009, the University of British Columbia, conducted tests with 600 participants to see how cognitive performance varies when people see red or blue. While the red groups did better on recall and attention to detail, blue groups did better on tests requiring invention and imagination. The study proved that the colour blue boosts our ability to think creatively; reaffirming the notion that blue is the colour of innovation.

When we talk about innovation and exclusivity, the brand that takes us by surprise is NEXA. Since its inception, the brand has left no stone unturned to create exclusive experiences for its audience. In the search for a colour that represents its spirit of innovation and communicates its determination to constantly evolve, NEXA created its own signature blue: NEXA Blue. The creation of a signature color was an endeavor to bring something exclusive and innovative to NEXA customers. This is the story of the creation, inspiration and passion behind NEXA:
