OpenAI Robot Rubik's Cube

San Francisco–based AI research lab OpenAI managed to successfully train a robotic hand to manipulate a cube with extraordinary dexterity. That’s right, using a reinforcement-learning algorithm, the hand taught itself how to manipulate the cube with a technique modeled after how animals learn. It simulated various conditions, and trained the robot to solve the cube to keep going regardless of any unknown physical factors. Read more for two videos and additional information.

AI Rubik's Cube System
University of California, Irvine researchers have developed an artificial intelligence system, called DeepCubeA, that can solve a Rubik’s Cube in about 20 moves, or an average of 1.2 seconds. For comparison, the current human world record clocks in at 3.47 seconds, but the Massachusetts Institute of Technology’s min2phase algorithm solved one in a mere 0.38-seconds, roughly three times faster than DeepCubeA.

Pyraminx Rubik's Cube Record Underwater
The Pyraminx is basically a regular tetrahedron puzzle in the style of Rubik’s Cube, divided into 4 axial pieces, 6 edge pieces, and 4 trivial tips that can be twisted along its cuts to permute its pieces. Just like it’s cube counterpart, the goal is to scramble the colors, and then restore them to their original configuration. Chinmay Prabhu, a 20-year-old from India, managed to achieve the record title for the Most Pyraminx (Rubik’s Cubes) solved underwater and all in a single breath. How did he prepare for this record setting run? He’s been solving Rubik’s cube puzzles since 2015. Read more for the video and additional information.

Self-Solving Rubik's Cube

Love Rubik’s Cubes, but can never quite solve one? Well, this innovative 3D-printed, self-solving version might be just what you need. A Japanese inventor made this a reality with a host of servo motors, Arduino boards and lots of trial & error. Unfortunately, there’s no detailed manual explaining how everything works, but its creator did upload a disassembly video. Continue reading to watch and for more information.

Rubika Rubik's Cube Bookcase

Rubika appears to be a floating 3D Rubik’s Cube, but it’s actually a cleverly-designed bookcase. Thanks to its three-color design, you can use each section for different items, including books, wine bottles, trinkets, and lots more. The shelves may not be optimal for video games, but with some tinkering, you could possibly use it to house your consoles. Continue reading for more pictures.

Infineon Rubik's Cube Machine

Most would consider solving a Rubik’s Cube in minutes to be impossible, but Infineon Technologies engineer Albert Beer has manged to create a robot that set a new world record by taking just 0.637-seconds to complete the puzzle. “It takes tremendous computing power to solve such a highly complex puzzle with a machine. In the case of ‘Sub1 Reloaded’, the power for motor control was supplied by a microcontroller from Infineon’s AURIX family, similar to the one used in driver assistance systems. Minimal reaction times play an even greater role in autonomous driving. A high data-processing rate is necessary to ensure real-time capabilities with clock frequencies of 200 MHz. As a result of this ability, a vehicle can safely and reliably apply the brakes when it approaches a barrier,” said Beer. Click here to view the first image in today’s viral picture gallery.

Rubik's Cube Solving Robot

Rubik’s Cube-solving robots are nothing new, but friends Jay Flatland and Paul Rose managed to build one you won’t believe is real. Though the setup may look complex, it’s only comprised of several webcams, 3D-printed frames and Arduino stepper motors. The custom software takes the image input from the cameras and converts it into a ‘unrolled’ that the solver can comprehend. After a few blazing runs, they managed to get the times down to 1.047s and an unreal 1.019s. Continue reading for more.

17x17x17 Rubik's Cube

According to Oskar van Deventer (above), Over The Top is a world-record 17x17x17 Rubik’s Cube, with many intricate patterns. It can take many, many hours to solve, yet one YouTuber who goes by RedKB has managed to do so, recording the entire process. Oskar says: “The puzzle was first presented live to the world at at the New York Puzzle Party Symposium, Saturday Feb. 12th.” Continue reading to watch the entire 7.5-hour non-timelapse video as well as the product link to where you can buy your very own 17x17x17 Rubik’s Cube.

It’s official, Cubestormer 3 has smashed the Guinness World Record for solving a Rubik’s Cube in the fastest time by solving a cube in just 3.253 seconds at the Big Bang Fair, held at the NEC in Birmingham. This third-generation model beat the previous non-human record of 5.27 seconds, set by the machine’s predecessor, the Cubestormer 2. Continue reading for two videos and more information.

In the mid-1970s, Erno Rubik worked at the Department of Interior Design at the Academy of Applied Arts and Crafts in Budapest. Although it is widely reported that the Cube was built as a teaching tool to help his students understand 3D objects, his actual purpose was solving the structural problem of moving the parts independently without the entire mechanism falling apart.
