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 "inspect" the cube beforehand. Times recorded by CubeStormer II are for the total solve including: image capture, software solution calculation and physical solve.

I made this song using only sounds from Apple products and Steve's 2005 Stanford commencement speech. Every instrument, including drums, has been sampled from a Mac product, tuned by ear, and replayed in the context of the song.
I hope you enjoy listening to this as much as I enjoyed making it.
RIP Steve. We'll miss you.

Rage Against the Machine guitarist and political activist Tom Morello is just one of the celebrities who has recently showed up in Lower Manhattan's Zuccotti Park to offer his support for the Occupy Wall Street movement. After performing for protesters this afternoon, Morello answered some questions with RT's Lucy Kafanov about Barack Obama, the state of America, bailouts, banks and the Occupy movement. Morello recently released the record World Wide Rebel Songs on behalf of his The Nightwatchman project.

Okay, so one night as I'm standing there brushing my teeth after my shower, this one decides the top of my head would make a great spot to chill out and groom herself and, well, it's now become a routine...
