A robot operable within a 3-D volume includes a gripper movable between an open position and a closed position to grasp any one of a plurality of objects, an articulatable portion coupled to the gripper and operable to move the gripper to a desired position within the 3-D volume, and an object detection system operable to capture information indicative of the shape of a first object of the plurality of objects positioned to be grasped by the gripper. A computer is coupled to the object detection system. The computer is operable to identify a plurality of possible grasp locations on the first object and to generate a numerical parameter indicative of the desirability of each grasp location, wherein the numerical parameter is at least partially defined by the next task to be performed by the robot.
