A cyclic redundancy check (CRC) is an error-detecting code commonly used in data communication and storage devices to detect accidental changes to raw data. This paper provides an overview and principle of CRC. Emphasis is placed on the implementation of the CRC algorithm by method of hardware as well as software. It is proved that the implementation method present has high practical value.
In this paper, a novel kind of electromagnetic driving mechanism for the spherical robot with omni directional movement is proposed. The equations for turning radius of the spherical robot were deduced, utilizing the method of geometrical analysis for robot traveling at low speed, as well as employing the principle of force-equilibrium and torque-equilibrium, considering the gyroscope effect and the...
