Lego Robot Masters the Rubik’s Cube in Seconds

Solving a Rubik’s Cube is challenging enough for humans, but engineer Mike Dobson took it a step further by creating a robot that can solve it in under 12 seconds—using only LEGO Mindstorms pieces.

Dubbed “Cubestormer,” this remarkable creation connects to a PC that processes the cube’s configuration and determines the solution. The robot features four mechanical “hands” that can rotate the cube in all directions with precision and speed.

A camera focused on the cube captures the current state of each face, sending this information to the computer, which then calculates and executes the optimal solving sequence.

Technical Highlights

  • Built entirely from LEGO Mindstorms components
  • Solves puzzles in under 12 seconds
  • Uses computer vision to analyze the cube
  • Features four manipulator “hands” for complete cube control.
