MIT robot solves Rubik's Cube in world record time: 0.38 seconds

This MIT robot solves it faster than any human ever could. It's a world record.

MIT robot breaks Rubik's Cube Record

  • A robot developed by MIT students Ben Katz and Jared Di Carlo has set the world record for solving the Rubik's Cube.
  • The fastest human record is held by Australian Feliks Zemdegs, who solved it in 4.22 seconds in 2018.
  • The original-size Rubik's Cube (3x3x3) has 43 quintillion possible combinations – and one solution.


There's a special place in our hearts for the Rubik's Cube. Pop culture icon and shorthand for intelligence, many dabblers have played around with this ingenious toy, and throughout the years there has been a number of competitions, challenges and variations for solving it.

The popularity of the Rubik's Cube can be attributed to the simplicity of its design combined with the mind-boggling complexity of the puzzle; there is one solution out of 43 quintillion possible combinations.

It was only a matter of time before the engineers and roboticists got to tinkering with it. Back in 2016, a robot set a new record for solving the cube in 0.637 seconds. But that wasn't fast enough for some. More recently, two MIT students, Ben Katz, a mechanical engineering graduate student, and Jared Di Carlo, a third-year electrical engineering and computer science student, thought they could one-up that.

"We watched the videos of the previous robots, and we noticed that the motors were not the fastest that could be used... We thought we could do better with improved motors and controls."

They set up a motor actuating within each face of the Rubik's cube controlled by electronics for control. With the assistance of webcams pointed at the cube, custom software determines the initial state of each face. Then, utilizing pre-existing software to solve the Rubik's Cube, the robot was guided to solve the puzzle.

The result? Their robot solved the Rubik's Cube in 0.38 seconds. It's safe to say that no human is physically capable of beating this speed. And we can add another achievement to the list of robots outperforming humans.

The human who has the fastest world record for hand-solving is Feliks Zemdegs. He was able to solve a Rubik's Cube in 4.22 seconds. Which is also nothing to sneeze at. The skills and talents robots are displacing are vast and varied to say the least. Not to mention surprising.

Now, watch the video a few more times and let your inadequate human hands fathom that speed.

Take your career to the next level by raising your EQ

Emotional intelligence is a skill sought by many employers. Here's how to raise yours.

Gear
  • Daniel Goleman's 1995 book Emotional Intelligence catapulted the term into widespread use in the business world.
  • One study found that EQ (emotional intelligence) is the top predictor of performance and accounts for 58% of success across all job types.
  • EQ has been found to increase annual pay by around $29,000 and be present in 90% of top performers.

Just How Much Land Does the Federal Government Own — and Why?

The rough beauty of the American West seems as far as you can get from the polished corridors of power in Washington DC.

Surprising Science

The rough beauty of the American West seems as far as you can get from the polished corridors of power in Washington DC. Until you look at the title to the land. The federal government owns large tracts of the western states: from a low of 29.9% in Montana, already more than the national average, up to a whopping 84.5% in Nevada.

Can VR help us understand layers of oppression?

Researchers are using technology to make visual the complex concepts of racism, as well as its political and social consequences.

Future of Learning
  • Often thought of first as gaming tech, virtual reality has been increasingly used in research as a tool for mimicking real-life scenarios and experiences in a safe and controlled environment.
  • Focusing on issues of oppression and the ripple affect it has throughout America's political, educational, and social systems, Dr. Courtney D. Cogburn of Columbia University School of Social Work and her team developed a VR experience that gives users the opportunity to "walk a mile" in the shoes of a black man as he faces racism at three stages in his life: as a child, during adolescence, and as an adult.
  • Cogburn says that the goal is to show how these "interwoven oppressions" continue to shape the world beyond our individual experiences. "I think the most important and powerful human superpower is critical consciousness," she says. "And that is the ability to think, be aware and think critically about the world and people around you...it's not so much about the interpersonal 'Do I feel bad, do I like you?'—it's more 'Do I see the world as it is? Am I thinking critically about it and engaging it?'"
