GelSight

High-resolution optical tactile sensors that give robots a sense of touch

GelSight makes camera-based optical tactile sensors that provide robots with high-resolution touch sensing, enabling precise manipulation of objects.

GelSight's tactile sensors work by capturing images of a gel-coated surface that deforms on contact, translating physical touch into rich spatial data about shape, texture, and force distribution at a resolution that conventional force sensors cannot achieve. This approach, originally developed at MIT, gives robotic grippers and hands the kind of detailed tactile feedback that humans rely on for dexterous manipulation tasks such as threading, assembly, and handling of fragile items. As humanoid robots push toward human-level manipulation capability, high-resolution touch sensing is increasingly recognised as a critical gap, and GelSight's technology is a leading commercial solution. The company works with robotics researchers and developers integrating tactile sensing into next-generation robotic hands and fingers.
