Remote center of motion (RCM) has become a rising research direction in the field robotics. It means that robot with rod-shaped end-effector operates through tiny hole on surface. Thereinto, key issue is deviation RCM point's position, apart from operating accuracy. In addition, considering an robotic system generally consists commercial and specialized end-effector, there exist some errors structural information related to attached end-effector. this article, remote cyclic scheme...

We experimentally demonstrated a method of generating continuously wavelength-switchable optical vortex beams (OVBs) in an all-fiber laser. A polarization-dependent microknot resonator (MKR) functions as comb filter and accounts for the narrow linewidth (0.018 nm) multiwavelength channels. The wavelength interval corresponds to free spectral range MKR. exploit fused SMF–FMF (single mode fiber–few fiber) coupler obtain broadband conversion successfully achieve switchable OVBs. As far we know,...
