This paper discusses how the state-of-the-art techniques in cyber-physical systems facilitate building smart warehouses to achieve promising vision of industry 4.0. We focus on four significant issues when applying CPS warehouses. First, efficient data collection: limited communication bandwidth meets numerous devices, we need make more effort study wireless scheduling strategies. Second, accurate and robust localization: localization is basis for many fundamental operations warehouses, but still needs be improved from various aspects like accuracy robustness. Third, human activity recognition: recognition can applied human–computer interaction remote machine operations. Fourth, multi-robot collaboration: robots will take place humans accomplish most tasks particularly a harsh environment, fully-distributed robot collaborating algorithms should investigated. Finally, point out some challenging future CPS-based warehouse, which could open new research directions.
