This machine solves the rubik's cube faster than the blink of an eye.

This 3x3x3 Rubik's cube solving speed is confirmed to be 0.103 seconds - faster than the blink of an eye.

This impressive achievement comes from four students from the Elmore Family School of Electrical and Computer Engineering, Purdue University (Indiana, USA), including Matthew Patrohay, Junpei Ota, Aden Hurd and Alex Berta. Their product, the robot named “Purdubik’s Cube”, has officially broken the world record, surpassing all previous competitors in both speed and accuracy.

“We solved it in just 103 milliseconds. A human blink takes 200-300 milliseconds. That means before you even realize what’s happening, the cube is solved,” Matthew shared on the school’s website.

The video recording the moment the robot worked left many people amazed, because the entire operation happened in just one blink of the camera - so fast that viewers almost didn't see anything. Only when replayed in slow motion did the "smoothness" and precision of the machine become truly apparent.

Matthew, now 23, said he got the idea in high school after watching a video of a group of MIT students building a robot that solved a Rubik’s Cube in 380 milliseconds. “I thought it was a really cool project. I wanted to do that one day,” he said.

After sharing their dream with their peers at school, they set out to make the project a reality. The final result not only surpassed their initial goal but also set a new record that is hard to match.

The official test took place in the school's lab on April 21. Purdubik's Cube is designed to recognize colors super fast, then automatically create an optimal algorithm to come up with the most efficient solution. The entire movement is performed by an extremely high-precision industrial control system, allowing the robotic arm to rotate the cube at a speed that the human eye cannot keep up with.

Associate Professor Nak-seung Patrick Hyun, who supervised the team of students, said the achievement was not only record-breaking, but also a testament to the increasingly sophisticated capabilities of modern mechatronic systems.

“This brings us closer to understanding and simulating ultra-fast response systems in nature, like how a fly's eye processes motion, or human neural reflexes,” he said.

The Purdue team's achievement broke the previous record set by Mitsubishi Electric Corporation (Japan) in 2024 with a time of 0.305 seconds. Looking back over a decade of improvement, the speed of solving the Rubik's Cube by robot has gone from over a minute to under a second, and now it has reached 0.1 seconds - a limit that seemed impossible to overcome.

World's fastest Rubik's cube solving robot milestones:

• 2009 – 1 minute 4 seconds (Peter Redmond, Ireland)
• 2011 – 5.27 seconds (Mike Dobson and David Gilday, UK)
• 2014 – 3.25 seconds (Mike Dobson and David Gilday)
• 2015 – 2.39 seconds (Zackary Gromko, USA)
• 2016 – 0.9 seconds → 0.637 seconds (Jay Flatland & Paul Rose; Albert Beer, Germany)
• 2018 – 0.38 seconds (Ben Katz and Jared Di Carlo, USA)
• 2024 – 0.305 seconds (Mitsubishi Electric, Japan)
• 2025 – 0.103 seconds (Purdue University, USA)

The tech world is waiting to see if the 0.103-second mark can still be broken, or if this will be the new boundary that humans and machines must accept.
