A method for operating a robotic system including determining an initial pose of a target object based on imaging data, wherein the initial pose is for estimating a resting orientation of the target object in a pickup area; calculating a confidence measure associated with the initial pose, wherein the confidence measure is for representing a likelihood of the initial pose being correct; and calculating a motion plan according to the confidence measure, the motion plan for executing a task based on picking up the target object from a start location, transferring the target object to a task location, and scanning one or more object identifiers between the start location and the task location.
