Robotic grasping of items in inventory system

摘要

Robotic arms or manipulators can be utilized to grasp inventory items within an inventory system. Information about an item to be grasped can be detected and/or accessed from one or more databases to determine a grasping strategy for grasping the item with a robotic arm or manipulator. For example, one or more accessed databases can contain information about the item, characteristics of the item, and/or similar items, such as information indicating grasping strategies that have been successful or unsuccessful for such items in the past.

1. A method comprising, under the control of one or more computer systems configured with executable instructions:
determining an identity of an inventory item based at least in part on information received from at least one of a barcode scanner or an RFID reader; accessing, based on the determined identity of the inventory item, a record in an item database including a set of stored characteristics of the inventory item; receiving information from one or more sensors about a detected set of characteristics of the inventory item; accessing information from the item database about characteristics of a plurality of inventory items; determining one or more inventory items from the plurality of inventory items having characteristics in common with at least one of the set of stored characteristics from the record or the detected set of characteristics; accessing grasping strategies from an item grasping database for a robotic manipulator for each of the one or more inventory items of the plurality of inventory items; identifying, from the grasping strategies of each of the one or more inventory items, a grasping strategy for the inventory item using the robotic manipulator; and generating instructions for the robotic manipulator to grasp the inventory item utilizing the identified grasping strategy for the inventory item.
