“…After that, Tang et al proposed a fiber grating-based method for measuring the three-dimensional force at the end of a minimally invasive surgical soft-body robot in response to the need for threedimensional force measurement at the end of a minimally invasive surgical soft-body robot [8]. And Ren et al used FBGs with machine learning to improve roughness measurement [9].…”

To identify the object edges and corners, silicone rubber embedded with a fiber Bragg grating (FBG) sensor is used as the manipulator skin. The Bragg wavelength-shift of FBG appears under axial strain. The strain distribution in the skin is analyzed by the simulation of edge and corner contact. The contact situation is determined by the observation of the wavelength-shifts and power changes of the FBG. This method can help identify and distinguish object edges and corners. This technique can be applied for robot tactile sensing and show broad application prospects. It is beneficial to the advancement of bionics.
