Abstract
Techniques described herein define a protection system for a multi-zone area where mobile drive units operate autonomously. For example, the protection system may receive sensor data in a particular detection space where the mobile drive units and potentially human operators enter and exit around a robotic arm. The sensor data may identify that an object has entered the detection space around the robotic arm. The sensor data may identify the likelihood of a mobile drive unit entering the area as compared to an operator entering the area. When the object is identified as an operator, any movement of the robotic arm may immediately stop. When the object is identified as the mobile drive unit, protection rules meant to protect the operator may be deactivated so that the mobile drive unit may receive inventory from the robotic arm.
