How can accidents be prevented when safety guards cannot be installed at retrieving areas?

Lack of accuracy and safety with general-purpose sensors

Automated storage is surrounded by safety guards to prevent accidents from occurring, that can be caused by people who enter the hazardous area unintentionally. However, since the safety guard is lower at the retrieval area of products, people might enter and they might touch the stacker lane. In order to prevent accidents, general-purpose sensors are installed to detect humans who are about to enter the hazardous zone, and to stop the equipment.

However, detection is not enough sometimes, when people are intentionally allowed to go in. Some applications use safety mat switches to detect human intrusion with weight, however, detection accuracy is not so high and switches may fail when strong pressure is applied, such as heavy objects, which leaves concerns about safety and convenience.
