  • Patent number: 12140774
    Abstract: An afocal sensor assembly detects a light beam with an aberrated wavefront. The afocal sensor assembly is configured to provide sorted four-dimensional (4D) light field information regarding the light beam, for example, via one or more plenoptic images. Based on the 4D light field information, a lossy reconstruction of an aberrated wavefront for one or more actuators of an adaptive optics (AO) device is performed. The AO device can be controlled based on the lossy reconstruction to correct the wavefront of the light beam. In some embodiments, the aberrated wavefront is due to passage of the light beam through atmospheric turbulence, and the lossy reconstruction and correction using the AO device is performed in less than 1.0 ms. The lossy reconstruction of the aberrated wavefront can have a phase accuracy in a range of ?/2 to ?/30.

  • Publication number: 20240286852
    Abstract: A robotic work cell uses an object separating mechanism to disperse bulk objects into a 2D arrangement on a horizontal surface and uses a vision system to generate pick-up (positional) data and rotational orientation data for each sequentially selected target object of the 2D arrangement. A pick-and-place robot mechanism uses the positional data to pick-up each target object and uses the rotational orientation data to reorientate the target object during transfer to a designated hand-off location. A carousel-type robotic end-tool disposed on a 4-axis object-processing robot mechanism rotates a gripper mechanism around a vertical axis to move the target object from the hand-off location to a designated processing location, where an associated processing device performs a desired process (e.g., label application) on the target object. In one embodiment the gripper mechanism is selectively rotatable around a horizontal axis to facilitate processing on opposing surfaces of the target object.

  • Publication number: 20240025647
    Abstract: An Inventory Management and Delivery System (IMDS system) manages product items within a climate-controlled enclosure (e.g., beverage case) in an automated manner using a product loading (ingestion) subsystem to convey product items into the enclosure's climate-controlled environment and utilizes two gantry robots and an articulated robot to perform all backstocking/storage and delivery/restocking operations. Product items are ingested on standardized crates to simplify backstocking/retrieval of various product types from an array of storage locations using the first (backstocking) gantry robot. During restocking operations, the required crates are retrieved from storage and individual items are extracted and by the articulated robot and transferred to the second (delivery) gantry robot. The second gantry robot utilizes a simplified channel-type delivery mechanism to deliver each product item to its associated display shelf location.

  • Patent number: 11642796
    Abstract: A human-like tactile perception apparatus for providing enhanced tactile information (feedback data) from an end-effector/gripper to the control circuit of an arm-type robotic system. The apparatus's base structure is attached to the gripper's finger and includes a flat/planar support plate that presses a pressure sensor array against a target object during operable interactions. The pressure sensor array generates pressure sensor data that indicates portions of the array contacted by surface features of the target object. A sensor data processing circuit generates tactile information in response to the pressure sensor data, and then transmits the tactile information to the robotic system's control circuit. An optional mezzanine connector extends through an opening in the support plate to pass pressure sensor data to the processing circuit. An encapsulating layer covers the pressure sensor array and transmits pressure waves generated by slipping objects to enhance the tactile information.

  • Patent number: 11542103
    Abstract: An automated food production work cell includes a robotic system that utilizes a food-grade robotic gripper to transfer individual food items. The robotic gripper is constructed using food-grade materials and includes finger structures that are linearly movably connected by linear bearings to parallel guide rods and are independently driven by a non-contact actuating system to grasp targeted food items disposed on a first work surface, to hold the targeted food items while the robotic system moves the gripper to a second work surface, and to release the targeted food items onto the second work surface. Encoding and external sensing systems facilitate fully automated food transfer processes. Optional sensor arrays are disposed on tip portions of the finger structures to provide feedback data (e.g., grasping force/pressure). Two or more pairs of independently controlled finger structures are provided to facilitate the transfer of multiple food items during each transfer process.

  • Patent number: 11433555
    Abstract: A robotic gripper (end effector) for an arm-type robotic system includes a hierarchical sensor architecture that utilizes a central data processing circuit to generate rich sensory tactile data in response to pressure, temperature, vibration and/or proximity sensor data generated by finger-mounted sensor groups in response to interactions between the robotic gripper and a target object during robotic system operations. The rich sensory tactile data is used to generate feedback signals that directly control finger actuators and/or tactile information that is supplied to the robotic system's control circuit. Sensor data processing circuits are configured to receive single-sensor data signals in parallel from the sensor groups, and to transmit corresponding finger-level sensor data signal on a serial bus/signal line to the central data processing circuit.
