Abstract: Apparatus and process for the installation of collars and/or nuts on fasteners, particularly in the aerospace industry. The apparatus includes an industrial base robot supporting a mounting base carrying a gimbal and rotary drive for a lightweight sensing robot with a fastening/torque tool. The sensing robot operates to align and position a spin preventing projection such as a hex key in a fastener end and a rotatable socket to torque a nut or collar onto the fastener held against rotation. The related process is accomplished by sensors in conjunction with the sensing robot aligning the hex key with a recess in the fastener end, inserting the key into the fastener to hold it against rotation, and spinning a nut or collar onto the fastener. A wrenching component is sheared from the nut and removed after the nut or torque is applied.
