EndoTac: An Endoscopic Camera-Based Tactile Sensor with High Sensitivity for Minimally Invasive Surgery. [PDF]
Adv Sci (Weinh)EndoTac presents a trocar‐compatible endoscopic vision‐based tactile sensor that uses a convex mirror to enlarge side‐facing tactile coverage during minimally invasive vessel palpation. Distorted tactile images are unwarped and processed by a learning model to estimate vascular deformation, enabling sensitive, spatially distributed tactile perception ...
