Risolviamo il Cubo di Rubik

The ARM-Powered CUBESTORMER 3 robot has smashed the Guinness World Record for solving a Rubik's cube, recording a time of 3.253 seconds at the Big Bang Fair in Birmingham, UK.
 
The robot employs an ARM-powered Samsung® Galaxy S4 smartphone powered by a Samsung Exynos 5 Octa application processor to analyze the cube and instruct four robotic hands to do the manipulations. ARM9™ processors also power the eight LEGO® MINDSTORMS® EV3 bricks which perform the motor sequencing and control.
 
CUBESTORMER 3 was designed, built and programmed by Mike Dobson and David Gilday, creators respectively of CubeStormer http://youtu.be/eaRcWB3jwMo and Android Speedcuber http://youtu.be/ylFb4pqAUd8 and more recently, co-creators of CubeStormer II http://www.youtube.com/watch?v=_d0LfkIut2M
 
The custom app developed for the smartphone uses the phone's camera to capture images of each face of the Rubik's Cube which it processes to determine the scrambled colors.The solution is found using an advanced two-phase algorithm that was originally developed for Speedcuber and then enhanced to make effective use of the dual-core ARM Cortex®-A9 based processor in a Samsung Galaxy SII smartphone powered by an Exynos 5 Dual application processor used in CubeStormer II. Further optimizations were made to take advantage of the eight-core big.LITTLE™ processor configuration in the Exynos 5 Octa application processor featuring four Cortex-A15 and four Cortex-A7 processors in the Galaxy S4.
 
Human speedcubers' solve times only include the physical manipulation of the cube and do not include some time which is allowed to CUBESTORMER 3 Smashes Rubik's Cube Speed Record

CubeStormer II solves the Rubik's Cube puzzle faster than the human world record.

This ARM Powered robot was designed, built and programmed by Mike Dobson and David Gilday, creators respectively of CubeStormer http://youtu.be/eaRcWB3jwMo and Android Speedcuber http://youtu.be/ylFb4pqAUd8.

The mechanics are constructed entirely from LEGO, including four MINDSTORMS NXT kits, with the addition of a Samsung Galaxy S II smartphone running a custom Android app as the robot's brain. Both the MINDSTORMS NXT kits and the Samsung Galaxy SII use a variety of ARM --based processors.

The app uses the phone's camera to capture images of each face of the Rubik's Cube which it processes to determine the scrambled colours. The solution is found using an advanced two-phase algorithm, originally developed for Speedcuber, enhanced to be multi-threaded to make effective use of the smartphone's dual-core ARM Cortex-A9 1.2GHz processor. The software finds an efficient solution to the puzzle which is optimised specifically for the capabilities of the four-grip mechanism. The app communicates via Bluetooth with software running on the ARM microprocessors in the LEGO NXT Intelligent Bricks which controls the motors driving the robot. During the physical solve, the app uses OpenGL ES on the phone's ARM Mali-400 MP GPU to display a graphical version of the cube being solved in real time.

Human speedcubers' solve times only include the physical manipulation of the cube and don't include some time which is allowed to CubeStormer II

Megaminxer is probably the first robot in the world to solve a Megaminx puzzle.

The Megaminx is a dodecahedron with 12 faces, each with 5 edges. Each face can be rotated in a similar way to the well-known Rubik's Cube puzzle.
The robot itself is built out of LEGO using a Mindstorms NXT kit for driving the mechanics. An HTC Desire smartphone running a custom Android app is the brain of the solver. The app uses the phone's camera to capture images of each face of the Megaminx which it then processes to determine the colors of the scrambled puzzle. After working out the solution, the app transmits the moves to the NXT controller via bluetooth to instruct it to solve the Magaminx.

The mechanism used by Megaminxer has been adapted from the Android Megaminxer - How to solve Megaminx with your phone

Software has been modified to use look-up tables to determine better combinations and is therefore to cut down the solving time to almost half. ARM Powered HTC Nexus One & LEGO solve Rubik's Cube in 15s

Possibly the first ever 4x4x4 LEGO Rubik's Cube solver?
This Rubik's Cube solver was designed and programmed using a Nokia N95 mobile phone, a LEGO Mindstorms NXT and lots of LEGO technic pieces! ARM Powered LEGO/Nokia 4x4x4 Rubik's Cube Solver

This Rubik's Cube solver was designed and programmed using a Nokia N95 mobile phone, a LEGO Mindstorms NXT and lots of yellow LEGO technic pieces! 

This is a Java application running on the Nokia N95.  This communicates with the NXT using a simple control program via Bluetooth.  The embedded camera in the N95 is used to capture an image of each face of the cube.  The application then processes these images to determine the colour of each piece of the cube.  Then the solution is worked out in a couple of seconds resulting in a sequence of approximately 30 moves.  The N95 then transmits these moves one at a time to the NXT to solve the puzzle.  This normally takes 3-4 minutes in real-time. ARM Powered Nokia and LEGO Rubik's Cube Solver

Build your own Rubik's Cube® solver from just a LEGO® MINDSTORMS® NXT 2.0 set.

ARM has previously demonstrated a variety of ARM Powered® robots constructed from smartphones and LEGO MINDSTORMS solving a variety of Rubik's Cube style puzzles including the world-famous CubeStormer II created by Mike Dobson and David Gilday.

These robots show the range of performance and presence of energy-efficient ARM processors from small, embedded microcontrollers to high performance application and graphics processors which are present in consumer products. 

ARM fully endorses STEM (Science, Technology, Engineering and Mathematics) education and adoption.   David Gilday, the creator of these robots, decided to try to use his robot activities to inspire young (and ARM Powered® MindCuber solves Void Cube

MicroCuber is probably the world's first robot to solve the Microbic puzzle.

Microbic is a tiny Rubik's Cube style puzzle, only 12mm across, designed by Evgeny Grigoriev See: http://www.youtube.com/watch?v=yBny_NvuxdU

MicroCuber's mechanism is built entirely from LEGO bricks including a MINDSTORMS NXT kit with the addition of a Sony Ericsson Xperia Mini smartphone running a custom Android app. The app uses the smartphone's camera to capture images of each face of the cube which it then processes to determine the colors of the scrambled puzzle. After working out the solution, the app transmits the moves to the NXT controller via bluetooth to instruct it to solve the cube.

It was quite a challenge to design a mechanism from LEGO bricks that is capable of manipulating such a small cube.

I'm flattered that Kenneth Brandon (@redKB) has included this video in his LEGO® MicroCuber

The CUBESTORMER 3 robot which uses ARM® processor technology will attempt to break the Guinness World Record for solving a Rubik's® Cube at the Big Bang Fair being held at the NEC in Birmingham, UK, on Saturday (March 15). 

The new robot employs an ARM-powered Samsung® Galaxy S4 smartphone equipped with an Samsung Electronics' Exynos 5 Octa application processor with an eight-core ARM big.LITTLE™ implementation featuring four Cortex-A15 and four Cortex-A7 processors to analyze the cube and instruct four robotic hands to do the manipulations.
