Title: Sensing Surfaces with GelSight
Our world is full of surfaces, and their fine scale geometry is important to how they look and feel for both robots and humans. I’ll describe a novel tactile sensor called GelSight that produces skin that is as soft as human skin but which has resolution hundreds of times better. It is based on an elastomer with special optical properties viewed by an embedded camera. With Gelsight we can build soft robot fingertips that measure shape, texture, shear, and slip with unprecedented sensitivity. The same technology can also be used measure 3D geometry at microscopic scales. Most optical techniques struggle when trying to measure the fine 3D geometry of specular or transparent materials (like metal or glass), but GelSight handles all materials with equal ease, delivering a pure shape-based signal. The technology is simple, and may be useful in many fields, such as dermatology, dentistry, industrial inspection, forensics,
Professor Edward Adelson has authored numerous papers in the fields of human perception, computer vision, image processing, computer graphics, and computational photography. Recently he has been working on artificial touch sensing, with application to robotics and microscale 3D measurement. His honours include The Rank Prize in Opto-electronics, the Adolph Lomb Medal, two IEEE “test of time” awards in computer vision, and election to the NAS.
