Abstract:
A system for robotic manipulation of a plurality of objects, comprising:a container for receiving the objects therein; a liquid disposed in said container and another fluid disposed above said liquid, said liquid having a surface layer forming an interface with said other fluid in said container, the objects being disposed at said interface between said liquid layer and said other fluid; means for applying energy to said liquid to establish oscillatory motion thereof sufficient to form a plurality of repeating vertically directed standing waves of said liquid at said interface; and, signal means coupled to said energy application means for supplying said energy with predetermined waveforms to dynamically position said standing waves in a predetermined pattern, said predetermined pattern of said standing waves dynamically arranging the objects in a predetermined configuration on said surface layer of said liquid.
