World record broken as robot solves puzzle cube at lightning speed

Two brothers from the U.K., Matthew and Thomas Pidden, have set a new Guinness World Record by designing a robot that solves a 4×4 puzzle cube in just 45.3 seconds, breaking a decade-old record. The project originated as Matthew’s undergraduate final project at the University of Bristol, combining his passion for Rubik’s Cubes and computer science. Matthew developed the software and control algorithms enabling the robot to analyze and solve the cube efficiently, while Thomas designed and 3D-printed many of the robot’s mechanical components. The robot features a central frame holding the cube and four mechanical arms that precisely rotate the cube’s layers based on calculated sequences. The brothers’ collaboration merged programming expertise with innovative engineering, resulting in a machine capable of rapid and accurate puzzle solving. After several trials and refinements, the robot achieved the record-breaking time by scanning the cube, computing the fastest solution, and executing a swift series of rotations. This accomplishment not only demonstrates advances in robotics technology but
