Abstract: In recent years, the robots of the Rubiks cube have emerged in an endless stream. The current Rubiks cube robots have defects such as instability, high cost and large size. For this, a new type of Rubiks cube robot is developed. Rubiks cube design uses a wide range of knowledge, including mechanical design, system control, visual inspection, algorithms and so on. In order to make it completely intelligent, the third-order cube is arbitrarily restored in the shortest time. The overall design structure consists of a camera and a two-finger robot. The camera captures the image and transmits it to the host computer. The STM32F103C8T6 minimum system controls the rotation of the robot arm fingers. In the case of low cost, the Rubiks cube is restored faster and more accurately than human calculations.

Key words: control, visual inspection, upper computer, two-finger manipulator
