Student Breaks World Record With Robot That Solves 4x4 Rubik’s Cube
A British student, Matthew Pidden, has developed 'Revenger', a robot that solves the 4x4 Rubik’s Cube in 45.305 seconds, breaking the machine world record. The project, completed in 15 weeks as part of his computer science thesis, uses dual webcams and a custom algorithm. The 4x4 cube, complex with over 7.4×10^45 combinations, was invented in 1981. Pidden plans to pursue robotics further at Imperial College London.
Key points
- Matthew Pidden, a 22-year-old student from the University of Bristol, created 'Revenger' within 15 weeks.
- 'Revenger' solved the 4x4 Rubik’s Cube in 45.305 seconds, surpassing the previous robot record of 1 minute and 18 seconds.
- The robot uses two webcams for visual analysis and a unique algorithm to determine solving moves.
- The 4x4 Rubik's Cube, also known as 'Rubik’s Revenge,' has an estimated 7.4×10^45 configurations, making it more complex than the classic 3x3 cube.
- The human record for solving the 4x4 cube is 16.79 seconds, set by Max Park in 2022.
- Pidden aims to pursue a master's in robotics at Imperial College London for further studies in AI and mechatronics.
Why it matters
- The development of 'Revenger' indicates increased interest in robotics within education, aligning with the IT trend focused on advanced robotics and AI.
- The 4x4 Rubik's Cube serves as a benchmark for testing algorithms in robotics, pointing to ongoing innovations in machine learning and automation.
- Pidden's success reflects the growing emphasis on incorporating hands-on projects in computer science programs as a pathway to advanced studies.
The achievement of 'Revenger' not only highlights a new milestone in robotic puzzle solving but also underscores the potential for students to push innovation in robotics and AI, marking a significant contribution to educational and technological advancements.
