Abstract:

A method and system for obtaining an identifier from an item is disclosed. The method includes autonomously operate a robotic structure to move an item along a predetermined path from a source location to a destination location, and autonomously operating the robotic structure to place the item at the destination location based at least in part on the plan. The item comprises one or more identifiers, and in response to a determination that at least one of the one or more identifiers was not obtained by one or more sensors, an active measure is performed to cause the one or more sensors to obtain the at least one identifier that was not obtained. The predetermined path corresponds to a path along which the item is moved from the source location to the destination location. The predetermined path is planned so that the item is moved within a threshold range of the one or more sensors while the item is moved along the predetermined path.

International Classification:

B25J 15/06

Abstract:

An end effector is disclosed. The end effector includes a first set of one or more suction cups of a first size having a first diameter, and a second set of one or more suction cups of a second size having a second diameter that is smaller than the first diameter. The end effector further includes a first actuation mechanism configured to apply suction to at least a subset of the first set of suction cups independently of actuation of the second set of suction cups and a second actuation mechanism configured to apply suction to at least a subset of the second set of suction cups independently of actuation of the first set of suction cups.

Abstract:

A robotic singulation system is disclosed. In various embodiments, sensor data image including data associated with an item present in a workspace in a workspace is received. The sensor data is used to determine and implement a plan to autonomously operate a robotic structure to move and place the item singly in a corresponding location in a singulation conveyance structure. The plan takes into consideration an attribute of the item determined based at least in part on the sensor data.
