Visual Servoed Robotic Mouse Oocyte Rotation
Both injection and biopsy of a mammalian cell require positioning and orientation of a biological cell in a three-dimensional space under a microscope. Manual cell manipulation and orientation is the most commonly used method that is based on a trial-and-error and direct cell poking approach. We present a system that is able to automatically rotate a mouse oocyte to a desired orientation based on pressure control and computer vision. Our methods improve existing techniques and provide a starting point for fast autofocusing and oocyte orientation prior to automatic ICSI or cell biopsy... Read more
