  "abstract": "This disclosure relates to a finger assembly for a manipulating apparatus including a rigid body and a deformable membrane received within an aperture. The deformable membrane includes a gripping surface arranged to grip an object being manipulated and visual markers. The finger assembly includes a reflective surface received within the rigid body opposite the deformable membrane to reflect an image of the visual markers, and an optical sensor arranged to view the visual markers and the reflected image of the visual markers, providing a stereoscopic view of the visual markers.",
