Abstract
An uncomplicated, compact and environmentally-immune sensor for the degree f articulation of finger joints in a remote underwater vehicle uses a length of an optical fiber connected to each finger joint. As the joint is rotated, the bending of the optical fiber changes the attenuation of light through the fibers and a detector monitoring this change provides a signal that is correlated to the degree of articulation.
