Force sensing apparatus and robot arm including the same
A multi-axis force sensing apparatus that is installed at an operational end of a surgery robot and is capable of measuring force acting upon the operational end and a robot arm including the force sensing apparatus includes a body that is elastically deformable and has a pipe form extending along an axial direction of the body, an optical fiber strain gauge attached to a surface of the body to measure a tension and compression of the body in at least three directions. The optical fiber strain gauge may include at least three fiber Bragg gratings (FBGs) that are attached to the surface of the body and extended in an axial direction of the body, a light source providing light to each of the FBGs, and a light detector detecting light reflected by the FBGs or light that has passed through the FBGs.
