Apparatus and method for detecting rotational state of smart rubik's cube

An apparatus for detecting a rotational state of a smart Rubik's cube, comprising:

• a printed circuit board (PCB) assembly, a plurality of Hall sensors, and a central processing unit, wherein the PCB assembly is disposed at a spherical core inside a Rubik's cube, the plurality of Hall sensors and the central processing unit are disposed at the PCB assembly, positions of the plurality of Hall sensors correspond to Rubik's cube sides respectively, and the central processing unit is connected to the plurality of Hall sensors, wherein
• the Hall sensors are configured to:
• acquire output level signals, and transmit the output level signals to the central processing unit;
• and
• the central processing unit is configured to:
• obtain an initial corner block arrangement array, an initial corner block direction array, an initial edge block arrangement array, and an initial edge block direction array, analyze the output level signals, update the initial corner block arrangement array, the initial corner block direction array, the initial edge block arrangement array, and the initial edge block direction array based on an analysis result, and generate Rubik's cube state data.
