  • Patent number: 11338451
    Abstract: Example systems and methods are described that are capable of gripping objects. In one implementation, a method involves identifying, by a processing system, an object to be gripped at a first location, commanding, by the processing system, a robotic actuator to move a gripper in a first direction so that the gripper makes contact with the object, wherein one or more teeth in a plurality of fingers associated with the gripper mechanically engage the object, and commanding, by the proceeding system, the robotic actuator to move the gripper in a second direction that is substantially opposite to the first direction, causing the gripper to grip the object.

  • Patent number: 11208289
    Abstract: A dish cart includes a top with a slot for receiving a lift arm that may be lifted up through the slot to raise or lower dishes. Lobe openings emanating from the slot receive lobes of a lift paddle secured to the lift arm. The cart may define a gap below the top for permitting insertion of the lift paddle and the lift arm. The cart may be adjusted to receive differently sized dishes by means of rails of different sizes or adjustable vanes. A dish drop station includes the lift arm and lift paddle and a lift mechanism for raising and lower the lift arm. The dish drop station may include a cart present sensor and include a lock for retaining the cart. The controller may be programmed to the lower the lift arm to an unlock position that disengages the cart lock.

  • Patent number: 11179852
    Abstract: An actuator and end effector are controlled according to images from cameras having a surface in their field of view. Vessels (cups, bowls, etc.) and other objects are identified in the images and their configuration is assigned to a finite set of categories by a classifier that does not output a 3D bounding box or determine a 6D pose. For objects assigned to a first subset of categories, grasping parameters for controlling the actuator and end effector are determined using only 2D bounding boxes, such as oriented 2D bounding boxes. For objects not assigned to the first subset, a righting operation may be performed using only 2D bounding boxes. Objects that are still not in the first set may then be grasped by estimating a 3D bounding box and 6D pose.

  • Patent number: 10952591
    Abstract: Example intelligent dishwashing systems and methods are described. In one implementation, a system includes an imaging system configured to capture at least one image of an article of dishware. A processing system analyzes the at least one image to determine a presence and a location of a stain on the article of dishware. Responsive to determining the presence of a stain, a cleaning system is configured to clean the location of the stain on the article of dishware.
