Lego Ev3 Rubik's Cube Solver. Physical ControlsRubic&#39s Cube MovementsMeasuring The Cube&#39s Initial StateFinding The SolutionJoining The PartsThe solutions uses three motors and one color sensor Referring to the above pic the left most motor called lift is used to roll the cube The second motor called base on top of which the cube rests is used to turn the cube The last motor called hand can either hold the top two layers of the cube on place while the base rotates (current state in the above pic) or move the color sensor to measurement position For each of these physical control there is a separate python class namely Base Hand and Lift When each of these classes are initiated motors reset their positions Lift finds both extreme positions Hand touches the rubic cube to find its extreme Base assume that it&#39s aligned when inited There is a standard notation how Rubic&#39s cube movements are marked For example R means that rotate the right face clockwise 90 degrees See the full notation for reference Given the individual physical controls the Moverclass allows using standard Rubic&#39s cube movement notation to modify the cube To make a single move it first orients the cube such that the desired face is on bottom and then uses hand to keep it on place while turning the face Python class called Inspectoruses Hand&#39s color measurement sensor to measure the initial state of the rubic cube The measurement is currently quite unstable and still under work Identifying the color is hard and depends on the lighting Especially detecting red and orange from each other can fail sometimes If the measurement fails the initial state can be corrected by hand Given the initial state the solution uses currently Ruwix online Rubic&#39s cube solver to find the optimal sequence of movements As it does not provide direct API access the cube input format was reverse engineered and the output is read by using Selenium This can be later replaced by custom solver The file solve_rubik_cubepy combines all of thes parts It first connects the ev3 by RPyC initializes the physical control classes measures initial states finds the solution path and makes the movements That&#39s it.

MindCub3r is a robot that can be built from a single LEGO MINDSTORMS EV3 home set (31313) or from EV3 Education Core and Expansion sets (45544+45560) to solve the well known Rubik&#39s Cube puzzle All MindCub3r software releases should work with LEGO EV3 firmware versions from v106H (home) and v106E (Education) onwards.
