Purdue Robot Achieves Rubik’s Cube Solving Record
Updated June 01, 2025
A team of Purdue University students has achieved a new Guinness World Record for the fastest Rubik’s Cube-solving robot. Their creation, dubbed Purdubik’s Cube, completed the puzzle in a mere 0.103 seconds, significantly surpassing the previous record. This achievement highlights advancements in robotics and engineering.
The Purdue team, consisting of Junpei Ota, Aden Hurd, Matthew Patrohay, and Alex Berta from the Elmore Family School of Electrical and Computer Engineering, optimized several aspects of their robot. These include high-speed, low-resolution camera systems, a reinforced cube, and a solving technique favored by human speedcubers.
Matthew Patrohay noted that previous record-holders typically focused on one new innovation. The Purdue students, though, improved the robot’s visualization speed. Thay employed Flir high-speed machine vision cameras, capturing images at 720×540 pixels with exposures as short as 10 microseconds.
The robot’s custom image detection system bypasses conventional image processing,focusing on a small 128×124 pixel region. Raw data is then sent to a high-speed color detection system, utilizing RGB measurements to quickly determine each square’s color.
Patrohay acknowledged the system might be “slightly less reliable” but emphasized that “even if it’s 90 percent consistent, that’s good enough as long as it’s fast.We really want that speed.”
For solving the cube, the team used Elias Frantar’s Rob-Twophase algorithm, which accounts for robots’ unique capabilities, such as simultaneously spinning two sides.They also implemented a “corner cutting” technique, initiating a turn on one side before another is fully completed.
What’s next
The Purdue team’s achievement sets a new benchmark in the Rubik’s Cube-solving robot field, paving the way for further innovations in robotics, machine vision, and algorithm optimization.
