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.

  • Outplacement is an underperforming $5 billion dollar industry. A new non-profit coalition by SkillUp intends to disrupt it.
  • More and more Americans will be laid off in years to come due to automation. Those people need to reorient their career paths and reskill in a way that protects their long-term livelihood.
  • SkillUp brings together technology and service providers, education and training providers, hiring employers, worker outreach, and philanthropies to help people land in-demand jobs in high-growth industries.

Do we really date based on our own ideals?

Do we really know what we want in a romantic partner? If so, do our desires actually mean we match up with people who suit them?

  • Two separate scientific studies suggest that our "ideals" don't really match what we look for in a romantic partner.
  • Results of studies like these can change the way we date, especially in the online world.
  • "You say you want these three attributes and you like the people who possess these attributes. But the story doesn't end there," says Paul Eastwick, co-author of the study and professor in the UC Davis Department of Psychology.
