Abstract

To achieve the force sensing at the sub-5 mm end effector of a continuum robot, optical fiber 'nerves' -incorporating the Fabry-Pérot (FP) cavity and step-etched fiber Bragg gratings (FBGs) was proposed to sense the multimodal forces (clamping force, 3-axis wrist force, and driving force) and shape awareness. The proposed laser-welded package solved the problem of clinical application adaptability, enabling the robot to withstand sterilization (15 cycles) and maintain an error of
