Abstract: A method and system for obtaining an identifier from an item is disclosed. The method includes autonomously operating a robotic structure having a robotic arm to pick an item using an end effector of the robotic arm along a predetermined path from a source location to a destination location according to a plan. The picked item is moved according to the plan. An active measure is determined to be performed at least in part to obtain an identifier determined to be missing based on information received via the communication interface from one or more sensors. The robotic structure is autonomously operated to place the item at the destination location based at least in part on the plan.
