Abstract
A square case containing ova and culture medium was vibrated with a voice coil motor to concentrate the ova at the center of the case. Only those ova which conform to the memorized shape are then selected with a picture processing device and are positioned one by one at the point of a holding pipette. A system with the functions mentioned was experimentally constructed. This system can automatically position any ovum in a certain position, thereby shortening the time of the process to search out an ovum and position it at the point of the holding pipette.
