Patent ID: 8561497

Claim:
A method of constructing a wrist assembly for a robotic arm, comprising: providing a first arm terminating in a first radius, and a second arm terminating in a second radius; providing a band having a first terminal portion with a first aperture defined therein, and a second terminal portion with a second aperture defined therein; extending the band around a portion of each of said first radius and said second radius; attaching the first terminal portion to at least one of said first arm and said first radius by way of a terminus, said terminus being equipped with a protrusion which extends through said first aperture such that said first terminal portion is rotatable about said protrusion, wherein the protrusion is adapted to rotatingly engage said first aperture, and wherein said terminus is further equipped with a first fastener suitable for attaching the terminus to a substrate; attaching the second terminal portion to at least one of said second arm and said second radius by way of a tension plate, said tension plate being equipped with a second fastener that extends through said second aperture such that said second terminal portion is rotatable about said second fastener; positioning the protrusion within the first aperture; and attaching the terminus to the substrate by way of the first fastener.
