“ARS is a complete system to solve Rubik’s cube: yes, another robot to solve the cube!
ARS is a three years long school project made with 3D printed parts and laser cut structures: an Arduino receives the correct sequence generated by an home made software, ARS Studio, through USB port, then moves forward and backward six stepper motors till the end.
ARS is based on great mr. Kociemba algorithm: as told on his website, Herbert Kociemba is a German cuber from Darmstadt, Germany who invented this algorithm in 1992 in order to find near optimal solutions to 3x3 cube, improving on the Thistlethwaite Algorithm.
In this Instructable instructions will be explained about building robot structure, and using the open source software developed to generate the proper sequence needed to solve the cube using Kociemba’s algorithm.
More infos on Kociemba and his work:
about algorithm
about God’s number, the number of moves an algorithm would take in the worst case to solve the cube. At long last, God’s Number has been shown to be 20 by Kociemba and his friends
