Abstract: A method of grasping and/or placing multiple objects by a gripper of a mobile robot. The multi-grasp method includes determining one or more candidate groups of objects to grasp by the suction-based gripper of the mobile robot, each of the one or more candidate groups of objects including a plurality of objects, determining a grasp quality score for each of the one or more candidate groups of objects, and grasping, by the suction-based gripper of the mobile robot, all objects in a candidate group of objects based, at least in part, on the grasp quality score. The multi-place method includes determining an allowed width associated with the conveyor, selecting a multi-place technique based, at least in part, on the allowed width and a dimension of the multiple grasped objects, and controlling the mobile robot to place the multiple grasped objects on the conveyor based on the selected multi-place technique.

Abstract: Methods and apparatus for controlling a robotic gripper of a robotic device are provided. The method includes activating a plurality of vacuum assemblies of the robotic gripper to grasp one or more objects, disabling one or more of the plurality of vacuum assemblies having a seal quality with the one or more objects that is less than a first threshold, assigning a score to each of the one or more disabled vacuum assemblies, reactivating the one or more disabled vacuum assemblies in an order based, at least in part, on the assigned scores, and grasping the one or more objects with the robotic gripper when a grasp quality of the robotic gripper is higher than a second threshold.

Abstract: Methods and apparatus for assigning a quality metric to an object to be grasped by a mobile robot are provided. The method includes receiving at least one image including a set of objects, processing the at least one image using a trained machine learning model to assign a quality metric to a first object of the set of objects in the at least one image, and controlling the mobile robot to perform an action based, at least in part, on the quality metric assigned to the first object.

Abstract: Methods and apparatus for grasping an object by a suction-based gripper of a mobile robot are provided. The method comprises receiving, by a computing device, from a perception system of the mobile robot, perception information reflecting an object to be grasped by the suction-based gripper, determining, by the computing device, uncertainty information reflecting an unknown or uncertain extent and/or pose of the object, determining, by the computing device, a grasp strategy to grasp the object based, at least in part, on the uncertainty information, and controlling, by the computing device, the mobile robot to grasp the object using the grasp strategy.
