摘要： A method for selecting a preferred robotic grasp of an object-of-interest using pairwise ranking includes: identifying a robotic candidate grasp usable to grasp the object-of-interest, the object-of-interest situated in an environment; receiving a grasp preference for a preferred candidate grasp of the object-of-interest; calculating a heuristic to describe a relationship of the candidate grasp to one or more of the object-of-interest and the environment; and using the heuristic and using the grasp preference, computing a pairwise ranking of two candidate grasps to determine an ordering of the at least two candidate grasps.
