  • Publication number: 20240139941
    Abstract: According to one embodiment, a handling system includes: a holding unit configured to hold an object; a holding state sensor configured to detect a holding state; a detection unit configured to detect the object and a holding posture; and a control device configured to control an operation of the holding unit. The control device performs: generating a carrying operation plan for allowing the holding unit to carry the object; calculating a safety factor indicating stability of a state in which the holding unit holds the object on the basis of the holding state, the holding posture, and the carrying operation plan; determining whether the carrying operation plan is to be changed on the basis of the safety factor; and changing the carrying operation plan on the basis of the safety factor when it is determined that the carrying operation plan is to be changed.

  • Publication number: 20240139973
    Abstract: According to one embodiment, a hand includes a gripper, a driver, and a controller. The gripper is configured to grip an object. The driver drives the gripper. When a stability when gripping the object is estimated, the controller causes the driver to perform a first motion to increase the stability. The stability is estimated based on contact information of the gripper for the object, and characteristic information including at least one of a size or a weight of the object.

  • Patent number: 11850748
    Abstract: A picking robot of an embodiment includes an acquisition unit, first and second calculation units, a control unit, and a grip unit. The acquisition unit acquires first area information. The first calculation unit calculates first position/posture information indicating a position/posture of a target object from the first area information. The second calculation unit calculates second position/posture information differing from the first position/posture information. The control unit grips the target object, based on the first position/posture information, controls a first operation of moving the target object to a second area. When a first operation result is inadequate, the control unit controls a second operation of arranging the target object at a position indicated by the second position/posture information in a posture indicated by the second position/posture information. The grip unit grips the target object and moves the gripped target object, based on the control by the control unit.

  • Publication number: 20230126805
    Abstract: According to an embodiment, a picking system having a holder, a controller, and a sensor is provided. The holder holds the object. The controller controls a motion of the holder. The sensor acquires information of the object. A failure detector of the controller detects a failure in a generation of the holding operation plan or a failure in a holding operation on the object by the holder. A determiner of the controller performs a first retry determination of deciding an operation for a retry in a case in which the failure detector detects the failure in the generation of the holding operation plan, and performing a second retry determination of deciding an operation for a retry in a case in which the failure detector detects the failure in a pickup of the object by the holder, the second retry determination being different from the first retry determination.
