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

Summary
The human history has witnessed three times industrial revolutions. Nowadays, we come to the fourth industrial revolution, i.e., Industry 4.0. Human Activity Recognition a) Popular Technologies for Industry 4.0 b) Research Topics for Smart Warehouse Application. We want to timely know their status and location context according to the data reported by the attached devices They are required to collaboratively accomplish some tasks that are repetitive and harmful to human beings. The four research topics are efficient communication scheduling, accurate and robust localization, human activity recognition, and multi-robot collaboration:. Efficient Communication Scheduling: In a CPS-based smart warehouse, there can be thousands of CPS devices, e.g., various sensors, RFID readers and tags, BLE beacons, and Wi-Fi APs. The CPS devices form a dense Local Area Network (LAN). We survey the underlying technologies to build a smart warehouse from the aspects of efficient communication scheduling, accurate and robust localization, multi-robot collaboration, and human activity recognition.
