Execution module, Rubik's cube reduction robot and using method for robot

The invention provides an execution module, a Rubik's cube reduction robot and a using method for the robot. The robot comprises an upper computer control module, a lower computer control module, the execution module and a power source module. The upper computer control module is used for obtaining initial state information of a Rubik's cube, generating Rubik's cube reduction control information according to the initial state information and sends the Rubik's cube reduction control information to the lower computer control module; the lower computer control module is used for controlling the execution module to carry out Rubik's cube reduction operation according to the Rubik's cube reduction control information; and the power source module is used for supplying power to any one or more of the upper computer control module, the lower computer control module and the execution module. According to the power source module, the mode that the execution module and the lower computer control module are electrified by one power source module is adopted, so that the use amount of cables is greatly reduced, a circuit is simplified, and meanwhile the whole robot becomes simple and attractive.
