In order to implement automation for warehousing, research is carried out in all-purpose tray of stacker crane under automatic storage and retrieval. The project design and construction were done of the stacker in warehousing jobs crane, which was supported by the single-chip microcomputer (MCU) to complete routine jobs for warehousing purposes like walking, lifting, shelving, unshelving, storing and retrieving, and etc. Verified by testings, capability of the MCU to effectively control a stacker crane qualifies the equipment to exercise its automatic storage and retrieval function. This simply-equipped and easily maintained MCU control lays the foundation for further automatization researches in warehousing industry.
