Patent attributes
Disclosed are a smart cube including a core housing having an accommodation space therein, a plurality of blocks having a surface formed therein to correspond to an outer circumference of the core housing and coupled to each other to be rotatable in a group around the core housing, and a controller configured to recognize a position of at least one of the blocks and to calculate a solution to place blocks having the same outer surface on at least one surface of the cube, wherein the block includes types of shaft blocks coupled to a center of each of top, bottom, front, rear, left, and right surfaces of the core housing, edge blocks in contact with each side surface of the shaft block, and corner blocks interposed between the adjacent edge blocks, the controller recognizes a position of at least one of the blocks based on a rotation direction and a rotation amount of the shaft block, and the plurality of blocks visually outputs a next step of a current step of the solution including a plurality of steps.
