Abstract
This paper depicts the system design of a robot that can recover the disrupted Rubiks Cube automatically. The robot is a typical mechatronics system consisted of the mechanical structure and the electrical system. The recovery procedures of the Rubiks Cube are shown as follows. Firstly, the color recognition of each face of the Rubiks Cube is conducted with an industrial CCD camera. Then the embedded recovery algorithm is called, and the recovery steps are achieved. Finally, the pneumatic manipulators are driven by the pressurized air controllable via an electrical relay array, the Rubiks Cube is recovered step by step following the recovery sequences. The Rubiks Cube robots have been exhibited in several science museums in China, they are well welcomed by the audiences.
