1. A method for manipulation of a plurality of objects, comprising the steps of: providing a source of objects locomotion; applying the source of objects locomotion to create a pattern of potential energy wells; applying the pattern of potential energy wells to a plurality of moving objects, thereby trapping at least a portion of the plurality of moving objects in the pattern; and moving the pattern of potential energy wells to manipulate the plurality of moving objects, wherein the source of objects locomotion comprises a polymer walker having legs with an therebetween which respond to stimuli by changing the angle to move the legs for effecting motion of the objects.
