The invention provides a magic cube-solving robot based on an intelligent mobile phone and relates to the field of robot devices. Magic cube color information is acquired through an upper computer unit, return logic calculation on the magic cube with disordered sequence is finished, a solving method is sent to a control unit on the robot through Bluetooth communication to control in real time, and an executing unit returns the three-step magic cube. An executing unit of the magic cube-solving robot adopts a driving mechanism which solves the problem that a wire is wound when a mechanical claw rotates to solve the problem that the wire is wound at a claw steering engine when a mechanical arm rotates. The magic cube-solving robot adopts a light-complementing auxiliary device to solve the problem of inaccurate image identification of a camera, which is caused by environment light.
