HMI-BASED PATTERN MODIFICATION FOR ROBOTIC PALLETIZING

A controller of a material handling system performs a method of creating a multidrop pattern of articles for robotic placement in layers on a pallet. A pattern is presented on a user interface of any currently positioned representations of articles on a pallet. A control affordance for inputing drag'n'drop and numeric inputs is presented on the user interface for robotic control operations to perform a multidrop of the more than one article in an end effector of a robotic arm for placement of the more than one article. User inputs are received that indicate placement position of a first subset of the more than one article. User inputs are received that indicate placement position of a second subset, which is mutually exclusive of the first subset, of the more than one article. The user inputs are converted into a place sequence of robotic control operations to perform a multidrop of the articles by the robotic arm.
